Human disturbance affects behavioural time allocation in a fiddler crab (Austruca annulipes) in Southern Thailand

Human disturbances affect the macroinvertebrate populations in coastal regions. They respond to disturbances by altering their density and behaviour. Therefore, many of them are used as bioindicator species of human disturbance. Here, we pioneer the use of fiddler crabs to examine whether they alter their behaviour under human disturbance. Male fiddler crabs possess one large claw used for courting (waving) and fighting, and one small feeding claw, whereas females have two feeding claws. They show several surface activities. This study investigates (1) the effects of human disturbance on density and sex-ratio, and (2) the effects of human disturbance, and sex on behavioural time allocations in Austruca annulipes. Their density, sex-ratio, and time allocations were investigated in human-disturbed area (DA) and nondisturbed area (NDA). They showed feeding, feeding and walking, walking, running, standing/vigilance, inside burrows, burrowing, grooming, fighting, and waving. The results showed that crab density was higher and the sex ratio was more male biased in NDA than in DA. Human disturbance and sex affected time allocations but their interaction had no effect. Crabs in DA spent more time running, standing, and inside burrows but less time walking, burrowing, fighting, and waving than crabs in NDA. Between sexes, males spent more time standing, burrowing, grooming, and fighting but less time feeding, and walking than females. This indicates that human disturbances force the crabs to spend more time on anti-predator and escape behavior (standing/vigilance, running, inside burrows) rather than courting (waving) and constructing burrows (mating/breeding sites), which are important for breeding.(AU)

Zoo visitors as a source of enrichment to reduce abnormal behavior in captive rhesus macaques (Macaca mulatta) in the Central Zoo, Kathmandu, Nepal

Overexpression of abnormal behavior among captive primates indicates poor management practices. The type, frequency, and contributing factors of abnormal behaviors vary highly across individual animals in captive settings. This study explored if sex, rearing history, the number of visitors, and type of visitor-monkey interactions affected the behaviors of captive rhesus macaques (Macaca mulatta) housed at the Central Zoo in Kathmandu, Nepal. Behavioral observations of six adult rhesus macaques (ages 4­12 years; two were rescued from the wild, and four were born in the zoo) were conducted using the focal animal sampling method. Observations were collected daily in two conditions (7:00­10:00 AM, without visitors present; and 10:00 AM­1:00 PM, with visitors present). During the visitor presence condition, instantaneous scan sampling also was implemented every 10 minutes to record the number of visitors and the type of visitor-monkey interaction. Resting, feeding and grooming were the most prevalent activities, and abnormal behavior ranked fifth throughout the observation period. Significant differences were observed in abnormal or stress-related behavior by sex and rearing history: females engaged in abnormal behavior more than the males, and rescued monkeys engaged in more abnormal behavior than the captive born. Abnormal behavior decreased, begging behavior increased as the number of zoo visitors and the extent of visitor-monkey interaction increased. We conclude that captive rhesus macaques respond to zoo visitors as a source of enrichment, and visitors' presence helps decrease abnormal or stress-related behavior levels.

Breeding behavioral activities of captive red pandas in Nepal

The red panda (Ailurus fulgens) population is decreasing, with less than 10,000 individuals in the wild because of habitat destruction, fragmentation, and illegal hunting. Captive breeding has become an increasingly crucial strategy for conserving endangered species, but efforts to generate self-sustaining populations have failed despite ample resources being allocated. Animals are often stressed in captivity, and it is necessary to examine reproductive behavior relating to the complexity of habitat requirements, dietary preferences, and, in particular, pregnant mothers and their sensitivity to disruptions. Using videography, we observed the reproductive behavior of two red pandas along with other behavioral activities in the Central Zoo, Kathmandu, Nepal. We collected behavioral data from December 2020 to June 2021 using scan and focal sampling. Reproductive behaviors (e.g., scent-marking, allogrooming, chasing, running, aggressiveness, mating, and feeding feces) were observed, along with behaviors like locomotion, climbing, standing, self-grooming, feeding, sleeping, self-play, and stretching. We observed 1­2% of reproductive behavior from total activity. Copulation was attempted on three occasions suggesting reproduction can be successful if animal husbandry is properly managed. We recommend zoo managers further refine strategies for captive breeding endangered species such as red pandas. Successful captive breeding benefits the zoo, and captive-born animals can mitigate extinction in the wild.

Behavior and nest architecture of the bee Caenohalictus alexandrei (Hymenoptera, Halictinae)

In Colombia, few studies have focused on nest architecture, behavior or sociality of wild bees. This study provides ba-sic information on the nests of Caenohalictus alexandrei and presents behavioral observations outside the nests, derived from direct field observation of 40 nests and 39 male sleeping cavities in two localities of the Savanna of Bogota, Colombia. We rec-ognized four different behavioral activities carried out by adult females: foraging, guarding, opening and closing of the en-trance of the nest, with foraging being the most frequent of them. The observed activities were carried out more frequently from 9:00 h to 13:00 h. Males were observed performing two behavioral activities in the sleeping cavities: staying at the cavity entrance and cavity departure. A third male activity, corporal grooming, was carried out outside the sleeping cavity. Our field observations indicate that more than one adult female was active simultaneously performing the different tasks within a sin-gle nest. The nests presented different levels of complexity in their architecture, depending on the age of the nest and num-ber of adult females in them. Descriptions of the nesting sites and behavioral activities as well as illustrations of the nest ar-chitecture are provided.(AU)

Stress in dogs during grooming in a pet shop

The objective was to study the stress level in dogs during grooming services in a pet shop. A total of 55 grooming services carried out in a pet shop in the city of Janaúba, MG, were evaluated and divided into four categories according to sex and body weight. The flowchart of the grooming process contained six steps that began with the transportation of dogs to the pet shop and finished with their return to the place of origin. Behavioral, physiological, and blood component evaluations were performed at different steps of the process. Changes in dog behavior and physiological parameters were observed primarily upon arrival at the pet shop and during drying. Employee characteristics also influenced dogs' behaviors. However, dogs were able to thermoregulate and maintain the homeostasis of leukocytes, glucose and cortisol in the blood.(AU)

Morte súbita pós-estresse não traumático em cão submetido a procedimento estético / No traumatic sudden death following stetic procedure in a dog / Muerte súbita por stress no traumático durante baño y corte en un perro

Ambientes destinados a procedimentos de banho e tosa expõem os animais a grande número de agentes estressores, como ruidos de secadores, alterações na temperatura e manipulação por desconhecidos, causando apreensão, ansiedade, medo e podendo levar ao óbito por traumas físicos em tentativas de fuga ou por colapso respiratório secundário a estresse agudo. Relata-se o caso de uma cadela da raça shih-tzu de 6 meses de idade, higida e sem sinais prévios de doença respiratória ou cardiovascular, que foi a óbito algumas horas após banho em per shop, com sintomas de estresse e insuficiência respiratória aguda e com alterações necroscópicas compatíveis com hemorragia e edema pulmonar, sem sinais de trauma craniano ou em outros órgãos. Ressalta-se a importância da minimização do estresse aos animais nos procedimentos de banho e tosa, a fim de evitar esses acidentes, bem como da presença do profissional responsável pelo estabelecimento, para que tomem medidas cabíveis e precoces para reverter esses quadros potencialmente fatais.(AU)

Environments for bathing and grooming procedures expose animals to a large number of stressors, such as dryer's noise, changes in temperature and manipulation by strange people, causing apprehension, anxiety and fear that can lead to death due to physical trauma in attempts to escape or due to respiratory collapse secondary to acute stress. We report the case of a 6-month-old female Shih-tzu, with no previous signs of respiratory or cardiovascular disease, who died a few hours after bathing in a pet shop, with symptoms of stress and acute respiratory failure and with necroscopic changes compatible with hemorrhage and pulmonar edema, without signs of cranial trauma or trauma in other organs.

Monitoring post-release behavioural activity of captive-bred urial (Ovis vignei punjabiensis) at Togh Managara Safari Park Khyber Pakhtunkhwa, Pakistan

Abstract The Punjab urial (Ovis vignei punjabiensis) is a globally threatened wild sheep species. In Pakistan the species is legally protected and bred in captivity to release into natural habitats to reinforce wild populations. Vigilance and feeding are critical to survival, though the degree to which captive-bred animals exhibit these behaviours post-release has rarely been investigated. We monitored the daily behaviours of five adult urial after release and classifying behaviours from 0600 hrs to 1800 hrs, replicating each one-hour period twice and recording four observations of each animal per hour. At the herd level, vigilance and feeding behaviours were exhibited equally. Males and females invested equal time in feeding, males were more vigilant (p = 0.001) and more aggressive (p = 0.010), and females were more restful (p = 0.019) or engaged in grooming (p = 0.044) or locomotion (p = 0.002). Females spent more time feeding than being vigilant (p = 0.002). Males maintained high levels of vigilance throughout the day. Patterns of resting 1300 hrs to 1500 hrs and feeding in early morning and late afternoon were common for both sexes. Behaviours classified as other were exhibited equally between sexes. Our results reveal positive indications of captive-bred urial balancing threat detection and energy acquisition post-release and exhibiting natural behaviours and activity patterns. We encourage assessment of survivorship to evaluate long-term effectiveness of captive breeding and release as a candidate restoration programme.

Resumo O Punjab urial (Ovis vignei punjabiensis) é uma espécie de ovelha selvagem ameaçada globalmente.

Ectoparasitoses de bovinos: biologia e epidemiologia como base para o controle / Bovine ectoparasites: biology and epidemiology as a basis for control

O principal carrapato para a pecuária mundial, Rhipicephalus microplus, é popularmente conhecido como "carrapato-do-boi" e tem preferência por parasitar animais taurinos, uma vez que os zebuínos apresentam uma resposta imunológica mais rápida e intensa quando são picados por esse ectoparasito. Além disso, a maior quantidade e espessura das papilas da língua, juntamente com a capacidade de autolimpeza ("self-grooming") do gado de origem indiana, facilita a remoção dos carrapatos. Por esses motivos, é mais comum ver animais taurinos apresentando elevadas infestações. Esse carrapato causa prejuízos econômicos da ordem de 3,24 bilhões de dólares anuais, que estão relacionados com as consequências do seu parasitismo, principalmente a redução da produção de leite e de ganho de peso dos animais. Além desses, também são observados danos ao couro (Figura 1), predisposição a miíases por Cochliomyia hominivorax, popularmente conhecida como "bicheira", e transmissão de agentes patogênicos do complexo da tristeza parasitária bovina, os protozoários Babesia bovis e Babesia bigemina e a riquétsia Anaplasma marginale.(AU)

First report of myiasis caused by Cochliomyia hominivorax in free-ranging giant otter (Pteronura brasiliensis) / Primeiro relato de miíase causada por Cochliomyia hominivorax em ariranha (Pteronura brasiliensis) de vida livre

Giant otters are territorial semi-aquatic mammals. It is common to find several individuals exhibiting wounds and scars due to intraspecific conflicts. Myiasis is a parasitic infestation on living tissues of vertebrates caused by dipterous larvae, that usually develops in freshly open wounds and can seriously threaten the host's health. Ectoparasites seem to be rare among giant otters and myiasis had not been recorded in this species until now. Here, is presented one record of myiasis in a free-ranging giant otter found dead in the Pantanal, Brazil. An ulcerative lesion was found in the frontoparietal region, from which 22 larvae were recovered and identified as Cochliomyia hominivorax. The low occurrence of ectoparasites in giant otters might reflect their semi-aquatic habits and their grooming behavior, which makes it difficult for parasites to remain on the skin. The injured otter probably got the larvae after an intraspecific fight. Agonistic encounters between groups of giant otters have been reported before and these fights can result in serious wounds or even death. It was hypothesized that the myiasis caused by C. hominivorax deteriorated the health of the infested giant otter, which prevented recovery and accelerated its death.(AU)

As ariranhas são mamíferos semiaquáticos habitantes do território brasileiro. É comum encontrar vários indivíduos apresentando feridas e cicatrizes devido a conflitos intraespecíficos. A miíase é uma infestação parasitária em tecidos vivos de vertebrados, causada por larvas de dípteros que, geralmente, se desenvolvem em feridas recém-abertas, podendo ameaçar seriamente a saúde do hospedeiro. Ectoparasitos parecem ser raros em ariranhas e, até o presente, não há relatos de miíase nesta espécie. Aqui, é apresentado um registro de miíase em uma ariranha de vida livre, encontrada morta no Pantanal, Brasil. Foi encontrada uma lesão ulcerativa na região frontoparietal, na qual foram recuperadas 22 larvas identificadas como Cochliomyia hominivorax. A baixa ocorrência de ectoparasitos em ariranhas pode refletir seus hábitos semiaquáticos e seu comportamento de limpeza, o que dificulta a permanência dos parasitos na pele. A ariranha ferida, provavelmente, se infestou com as larvas após uma briga intraespecífica. Encontros agonísticos entre grupos de ariranhas já foram relatados antes, e essas lutas podem resultar em ferimentos graves ou até mesmo em morte. Foi hipotetizado que a miíase causada por C. hominivorax deteriorou a saúde da ariranha infestada, o que impediu a recuperação e acelerou sua morte.(AU)

Maternal behavior in domestic dogs

For the past years, there is an increased interest for maternal behavior in human’s best friend – the dog. Indeed, studies show that the quality of mothering is not only important for the survival of the puppies during the first weeks of life, for the bonding process but recently it shows that it might have a long-lasting impact on the puppies’ future performance. However, how to define and measure maternal behavior? From the early studies to nowadays, the display of acts from the bitch right prior to parturition (preparation phase), and then continuously toward the puppies until weaning are the repertoire of actions that define maternal behavior. For the scientific community, maternal care is quantified as a principal component assessing attitudes that are easy to measure from the dam to the puppies such as: the time spent in contact, time and/or frequency of licking/grooming and time and position of nursing. Though, there is still a need to elucidate different aspects of maternal behavior in the dog, for example the effect of genetics, the impact of the emotional state of the bitch and the quality of maternal behavior, the role of hormones, the possibility to improve maternal behavior, there is some information to share. The idea is to give an overview of maternal behavior that permits veterinarians, breeders to identify and prevent problems to optimize the dog welfare.

Mapeamento do mercado pet e insumos veterinários na região do Cariri / Pet and input market mapping veterinary in the Cariri region

O presente trabalho teve por objetivo relatar a situação mercadológica da região do Cariri, enfatizando a importância da caracterização e da análise da estrutura dos estabelecimentos que englobam o agronegócio. A pesquisa foi realizada com a aplicação de dois questionários técnicos, com visitas em clínicas veterinárias, pet shops e casas agropecuárias, dos municípios cearenses de Barbalha, Juazeiro do Norte e Crato. Os resultados revelaram a diversidade de estabelecimentos comerciais com predominância nas casas agropecuárias(46,0%), pet shops (23,0%) e clínicas veterinárias (8%). Destaca-se, principalmente, a atuação do médico veterinário, com a realização de procedimentos cirúrgicos, vacinação, atendimento clínico e a campo. Além disso, aponta-se a prestação de serviços farmácia e hotel pet, comércio de animais, banho e tosa e fisioterápicos, disponibilizados em pet shops e clínicas veterinárias na cidade do Crato e Juazeiro do Norte. Com a realização da pesquisa, foi possível quantificar as espécies animais que abrangem o setor Pet Food na região. Ademais, os dados da pesquisa de campo mostraram que existe uma ampla comercialização de insumos para alimentação animal, disponibilizados, principalmente, nas casas agropecuárias. Com a análise dos dados coletados verifica-se a importância do agronegócio para o desenvolvimento sustentável da região do Cariri, possibilitando a geração de emprego e renda para o homem do campo e para os profissionais prestadores de serviços.

Agribusiness is a set of operations in the production chain, from agricultural work to commercialization, which has great importance to Brazil and other countries that have an economy based on agriculture and livestock. This study aimed to report the market situation in the Cariri Region, emphasizing the importance of characterizing and analyzing the structure of establishments that include agribusiness. The research was carried out with the application of two technical questionnaires on visits to veterinary clinics, pet shops and agricultural houses in the municipalities of Barbalha, Juazeiro do Norte and Crato. The results revealed the diversity of commercial establishments with predominance in agricultural houses (46.0%), pet shops (23.0%) and veterinary clinics (8%). The Veterinarian's performance was particularly noteworthy, with surgical procedures, vaccinations, clinical and field care. In addition, the provision of pharmacy and pet hotel services, animal trade, bathing and grooming and physiotherapy, available in pet shops and veterinary clinics in the city of Crato and Juazeiro do Norte. With this work, it was possible to quantify the animal species that comprise the Pet Food sector in the region. In addition, data from the field research showed that there is a wide commercialization of inputs for animal feed, available mainly in agricultural houses. With the analysis of the collected data, it is possible to verify the importance of agribusiness for the sustainable development of the Cariri Region, enabling the generation of employment and income for rural people and professional service providers.

Agribusiness is a set of operations in the production chain, from agricultural work to commercialization, which has great importance to Brazil and other countries that have an economy based on agriculture and livestock. This study aimed to report the market situation in the Cariri Region, emphasizing the importance of characterizing and analyzing the structure of establishments that include agribusiness. The research was carried out with the application of two technical questionnaires on visits to veterinary clinics, pet shops and agricultural houses in the municipalities of Barbalha, Juazeiro do Norte and Crato. The results revealed the diversity of commercial establishments with predominance in agricultural houses (46.0%), pet shops (23.0%) and veterinary clinics (8%). The Veterinarian's performance was particularly noteworthy, with surgical procedures, vaccinations, clinical and field care. In addition, the provision of pharmacy and pet hotel services, animal trade, bathing and grooming and physiotherapy, available in pet shops and veterinary clinics in the city of Crato and Juazeiro do Norte. With this work, it was possible to quantify the animal species that comprise the Pet Food sector in the region. In addition, data from the field research showed that there is a wide commercialization of inputs for animal feed, available mainly in agricultural houses. With the analysis of the collected data, it is possible to verify the importance of agribusiness for the sustainable development of the Cariri Region, enabling the generation of employment and income for rural people and professional service providers.(AU)

Pharmacological evaluation of the hydro-alcoholic extract of Campomanesia phaea fruits in rats / Avaliação farmacológica do extrato hidroalcoólico dos frutos da Campomanesia phaea em ratos

Campomanesia phaea (Myrtaceae), popularly known as cambuci, is one of several species of plants producing comestible fruits, largely used in human nutrition. Despite its consumption and economic potential, limited scientific research is available on the Campomanesia, especially those related to its therapeutic benefits. It is reported by traditional medicine the use of the plant in the treatment of different disorders, such as cardiovascular and nervous system disturbances. So, the aim of this study was to carry out the pharmacological evaluation of the hydro-alcoholic extract (HAE) of Campomanesia fruits in rats by screening consisting of tests: a) neuropharmacological observation, b) test on the cardiovascular system. The HAE, prepared from the extraction of fruits with water/ethanol, was concentrated and freeze-dried. Behavioral responses in rats were investigated in open field test and the cardiovascular actions were investigated by a register of indirect blood pressure and the register of spontaneous beating rate right atrium. The results revealed that HAE induced grooming, hypotension and bradycardia. So, this study identified an action on the central nervous system, represented by grooming, and a cardiovascular activity of Campomanesia. The hypotension, attributed in part to bradycardia, was not related to a cholinergic effect, discarding a possible cholinomimetic action of the plant that could justify both cardiovascular and central actions.(AU)

Campomanesia phaea (Myrtaceae), popularmente conhecida como cambuci, é uma das várias espécies de plantas que produzem frutos comestíveis amplamente utilizados na nutrição humana. Apesar de seu consumo e potencial econômico, há poucas pesquisas científicas sobre a Campomanesia, especialmente aquelas relacionadas aos seus benefícios terapêuticos. É relatado pela medicina tradicional o uso da planta no tratamento de diferentes distúrbios, tais como distúrbios do sistema nervoso e cardiovascular. Assim, o objetivo deste estudo foi realizar a avaliação farmacológica do extrato hidroalcoólico (EHA) dos frutos de Campomanesia phaea em ratos através de triagem composta pelos testes: a) observação neurofarmacológica, b) testes no sistema cardiovascular. O EHA, preparado a partir da extração de frutos com água/etanol, foi concentrado e liofilizado. As respostas comportamentais em ratos foram investigadas em teste de campo aberto e as ações cardiovasculares foram investigadas pelo registro da pressão arterial indireta e o registro da taxa de batimentos cardíacos espontâneos em preparações isoladas de átrio direito. Os resultados revelaram que EHA induziu grooming, hipotensão e bradicardia. Assim, este estudo identificou uma ação da Campomanesia sobre o sistema nervoso central, representada por grooming, e uma atividade cardiovascular. A hipotensão, atribuída em parte à bradicardia, não está relacionada a um efeito colinérgico, descartando uma possível ação colinomimética da planta que pudesse justificar tanto as ações cardiovasculares quanto as centrais.(AU)

Criteria for assessing peripheral nerve injury: behavioral and functional assessment in non-operated Wistar rats

Purpose To evaluate the normality pattern in functional tests of peripheral nerves. Methods Sixty female and sixty male Wistar rats were submitted to vibrissae movement and nictitating reflex for facial nerve; grooming test and grasping test for brachial plexus; and walking tracking test and horizontal ladder test for lumbar plexus. The tests were performed separately, with an interval of seven days between each. Results All animals showed the best score in vibrissae movement, nictitating reflex, grooming test, and horizontal ladder test. The best score was acquired for the first time in more than 90% of animals. The mean of strength on the grasping test was 133.46±12.08g for the right and 121.74±8.73g for the left anterior paw. There was a difference between the right and left sides. There was no difference between the groups according to sex. There is no statistical difference comparing all functional indexes between sex, independent of the side analyzed. The peroneal functional index showed higher levels than the sciatic and tibial functional index on both sides and sex. Conclusions The behavioral and functional assessment of peripheral nerve regeneration are low-cost, easy to perform, and reliable tests. However, they need to be performed by experienced researchers to avoid misinterpretation.(AU)

Animal performance and welfare of giant freshwater prawn (Macrobrachium rosenbergii) subjected to feed restriction

Behavior activities of giant freshwater prawn Macrobrachium rosenbergii juvenile, their performance, and acquired lesions when under temporary feed restrictions were analyzed. Five animals/experimental units (10 prawns/m2 ) were employed for treatments DFL ­ daily feed supply in the light phase; DFD ­ daily feed supply in the dark phase; AFL ­ alternating feed supply in the light phase; and AFD ­ alternating feed supply in the dark phase, for a 24-hour period, with four replications each. Prawns were fed a pellet diet, twice a day, with 10% of their biomass/day. Specimens were monitored during 60 consecutive days, with behavior recording daily and weighed every 10 days, with assessment of lesions and/or amputated limbs at the end of the experimental period. Types of behavior comprised exploring, grooming, inactivity, crawling, swimming, excavation, burrowing, agonism, and feed ingestion by scan sampling, with instantaneous registration every 60 s, in 15-min windows, before and after feed, in light and dark phases. Feed restricted in alternate days during light and dark phases did not interfere in growth or survival of the specimens, with increase in apparent feed intake and less feed conversion ratio and specific growth rate. Agonistic behavior was higher in specimens with feed restrictions, with an increase in the number of lesions and amputations. The above demonstrates welfare decrease in farmed M. rosenbergii and depreciation in the quality of the final product.(AU)

Activity budget and social behavior of urban capuchin monkeys, Sapajus sp. (Primates: Cebidae)

Constant changes in natural environments impose challenges to wild animal populations, especially those that depend on social life. We gathered data on the activity budget and social interactions of a capuchin monkey (Sapajus sp.) group of 17 individuals confined to an urban green area receiving human food supplementation. We observed the capuchins between 7:00 am and 5:00 pm, three days a month, between January 2012 and June 2013 (total of 530 hours of direct observations). We collected 15,208 behavioral records through instantaneous scan sampling and 2,538 events of social interaction in an adapted version of the “all occurrences” method. Activity budget of capuchins was dominated by traveling (42%) and foraging (38%), followed by feeding (10%), social interactions (5%), resting (4%), and others (2%). Except for feeding, the time spent on other activities varied across sex-age classes. Social interactions of capuchins were dominated by affiliative interactions (80%), mainly social play, followed by agonistic (11%) and cooperative (10%) interactions. Sexual interactions were rare (0.4%) and often involved juveniles (45% of the events). Juveniles performed most of the social interactions, followed by the alpha male, and were the main receptors of grooming, food sharing, and agonism. On the other hand, they were the main group involved in allocarrying of infants. Grooming between females and from them to alpha male was infrequent. However, grooming of the alpha male towards the adult females was frequent. We interpreted the deviations in the activity budget and social interactions of the urban capuchins as effects of human food supplementation and restriction on dispersal, illustrating the behavioral ability of capuchin monkeys to adjust their activity in human-altered environments.
