RESUMO

Termites are one of the key ecosystem engineers in tropical forests where they play a major role in decomposition rates, both above and belowground. The interest in termite ecology and biogeography has increased in the last few decades; however, the lack of comparable data has limited the wider impact of termite research. For Ecuador, termite studies are relatively rare and comparable data that are collected using standardized sampling methods are missing. In this study, we aim to 1) provide comparable data of termite species and feeding-group diversity from two primary forests in Ecuador and 2) explore the differences in termite species and feeding-group diversity between the two forest sites. Sampling took place in the national parks of Yasuní and Podocarpus where three belt transects (100 × 2 m) following Jones and Eggleton (2000) were conducted in each forest. We found that termite species richness was higher in Yasuní (56 species) than in Podocarpus (24 species) and that 57% of the sampled termite genera had never previously been recorded in Ecuador. The inter-site species dissimilarity was almost complete (Bray Curtis (±SD), 0.91 ±â€…0.01), which may have been linked to the difference in tree density and species richness in the two forests. Termite feeding-groups diversity was significantly higher in Yasuní than in Podocarpus with the exception of soil-feeding termites which may have been due to competition between humus- and soil-feeding species.

RESUMO

Wood-decaying fungi are important components of forest ecosystem, mainly growing on the dead wood and decomposing lignin, cellulose, and hemi-cellulose. Understanding the ecological distribution of wood-decaying fungi are necessary to reveal their ecological function. In this study, we investigated wood-decaying fungi at three sites with different altitudes in Laojunshan National Park. Fruit bodies of fungi were collected and identified based on morphological and molecular analy-sis. In total 68 species were recorded, belonging to 40 genera, 21 families and 8 orders. Polyporaceae, Fomitopsidaceae, and Hymenochaetaceae were dominant families. The floral composition showed a distinct north temperate character, which was the most important element among all the bio-geographical elements with the highest percentage of 38.2%. These wood-decaying fungi can be divided into two ecological types: saprophytic (63 species) and ectomycohizal (5 species). Among these saprophytic fungi, 51 species could cause white rot and 12 species cause brown rot. The amounts of fungal species in deciduous broad-leaf forest (DBF), coniferous broad-leaved mixed forest (CBMF) and dark coniferous forest (DCF) were 34, 26 and 22, respectively. Postia fragilis and Stereum hirsutum, distributed in all the three types of forests, were dominant species of Laojunshan National Park.

RESUMO

Improvement of the sound environment is essential for improving the overall quality of the urban environment and for reflecting the characteristics of a city. Unfortunately, some soundscapes in cities are gradually being destroyed by the rapid development. Therefore, it would appear that the preservation of soundscapes is as necessary and crucial as noise control in cities. In this paper two field studies were carried out at two stages to explore the types and characteristics of urban soundscapes that should be preserved, based on the example of Tianjin, China. At stage one, 2504 respondents participated in social surveys to recommend the soundscapes worthy of preservation in the city. At stage two, a group soundscape walk with twenty-three participants was carried out to explore the characteristics of soundscapes worthy of preservation suggested by the respondents at the first stage. The following results were obtained: (1) regarding the attitude towards the urgency of soundscape preservation, 79% of the respondents thought it was urgent or very urgent, with an average score of 4.04 (five-point numeric scale was used and five meant very urgent). (2) The majority of soundscapes worthy of preservation were located in urban parks and historic districts with respective proportions of 66% and 20%. The top three sound source categories of these soundscapes were social/communal sounds (talking, bells, laughter, and sounds from human activities), animal sounds (birdsong and sounds from non-domesticated animals) and water sounds. (3) Relaxation, vibrancy, representativeness, strength, and richness were principal characteristics of the soundscapes worthy of preservation. (4) Based on their characteristics, these soundscapes were classified into five clusters using hierarchical cluster analysis (HCA). They were clusters of relaxing nature soundscape, vibrant nature soundscape, vibrant human activity soundscape, culture-related soundscape and traditional soundscape. The dominant characteristic of each cluster was driven by its sound mark rather than the dominant sound.

RESUMO

Achieving biodiversity conservation objectives and targets requires environmental management agencies to undertake monitoring. Several management practices have been used but are they successful? Using SANParks as an example, we focus on three cases of national parks that use different techniques to implement environmental monitoring. We assessed a top-down, bottom-up and an integrated approach to setting targets using Table Mountain, Mokala and Bontebok National Parks respectively. Attainment of national and international objectives from State of Biodiversity assessment scores and achievement of objectives within individual Park Management Plans served as measurement criteria. We highlight several reasons for lack of achievement of objectives and targets for protected areas and illustrate that setting of objectives and monitoring must have complete full integration into park operations, both on staff and budget scales, rather than be seen as an external function from service divisions within parks or external service providers. An integrated approach to setting of objectives and targets of national and international importance is best achieved via the robust implementation of strategic adaptive management with interventions, measurement, reflection and adaptation integrated as learning by doing. Our results may not be unique but only a few organizations implement adaptive management in its full context.

RESUMO

Four typical park water bodies located in the main urban area of Shijiazhuang city were selected to study the relationships between water quality and the community structure and diversity of nirS denitrifying bacteria. The results showed that the nitrogen concentration ranged from 4.43 to 13.83 mg·L-1 in four park water bodies, which exhibited notable nitrogen pollution characteristics. Based on the characteristic index analysis of three-dimensional fluorescence spectra, the four park water bodies all exhibited strong autochthonous components and low humus characteristics. The results of Illumina high-throughput sequencing indicated that most of the nirS denitrifying bacteria showed significant differences in dominant genus. The unclassified_Bacteria (53.52%), Pseudomonas (60.48%), and Rhodobacter (46.94%) were the dominant bacteria in Yuxi park, Shuishang park, and Chang'an park, respectively. In comparison, unclassified_Bacteria (36.19%) and unclassified_Proteobacteria (23.44%) were the dominant bacteria in Shiji park. Redundancy analysis showed that denitrification bacteria in Yuxi park were mainly affected by nitrate, total nitrogen, and dissolved oxygen; denitrification bacteria in Shuishang park were greatly affected by total phosphorus; denitrification bacteria in Chang 'an park were mainly affected by ammonia and nitrous nitrogen; and denitrification in Shiji park were mainly affected by total phosphorus, nitrite, and ammonia. Overall, the water quality and the community structure of nirS denitrification bacteria exhibited significant differences in park water bodies. Further research could contribute to the understanding of water quality characteristics and the denitrifying community structure of urban water systems, and develop efficient denitrifying bacterial agents.

RESUMO

BACKGROUND: A rapidly growing body of research suggests that qualities of the built environment can promote active living among children and youth. Nevertheless, shortcomings in the current evidence for understanding which built environment characteristics provide opportunities for taking part in activities in childhood remain. This study aimed to examine whether population density, green spaces, and facilities/amenities are associated with participation in leisure-time physical activity (PA), organized activities, and social activities with friends and peers in Norwegian 8-year-olds. METHODS: Data from a sample of 23,043 children from the Norwegian Mother and Child Cohort Study (MoBa) were linked with geospatial data about the built environment. The questionnaire data reported by mothers provided information on the children's leisure activities. We computed exposure to neighborhood population density and access to green spaces and facilities/amenities within 800- and 5000-m radii of the participants' home addresses using geographic information systems. Associations were estimated using logistic regression models. RESULTS: We found beneficial associations between having a park within 800-m and more leisure-time PA during the summer. Furthermore, children living in neighborhoods with higher proportions of green space participated in more PA during the winter. More densely populated areas and access to facilities were associated with participation in organized and social activities. Specifically, we observed that more playgrounds/sport fields in the neighborhood were the strongest and most consistent correlate of activity participation in Norwegian 8-year-olds by being related to more socialization with friends and peers. CONCLUSION: This population-based study underscores the importance of access to a variety of venues and opportunities for different activities in the immediate neighborhood surroundings and in the greater community to support participation in physical activity and organized and social activities in childhood.

RESUMO

Specimens of a limnoterrestrial tardigrade collected from moss in New Hampshire, USA and Newfoundland, Canada were identified as belonging to the genus Milnesium. Morphometric data and genetic analysis of the COI gene demonstrated that animals collected from these sites represent the same species. Specimens most closely resemble Milnesium granulatum, a South American species that has been reported also from Great Smoky Mountains National Park (GSMNP), USA. New Hampshire and Newfoundland animals have the same adult claw configuration and cuticular granulation pattern as M. granulatum. Theira* (i.e., normalized to correct for allometric effects) pt values differ from GSMNP M. granulatum in having a more posterior stylet support insertion point. However, all their morphometric values overlap in range with GSMNP specimens. Unlike some other species in the genus, the claw configuration of New Hampshire Milnesium cf. granulatum shows no ontogenetic change in claw configuration. A short (269 bp on average) fragment of the internal transcribed spacer region 2 (ITS-2) was sequenced for 20 New Hampshire adults and from siblings hatched in the laboratory from 8 egg clutches. Genetic diversity among New Hampshire adults was 0.0-3.7%. Multiple haplotypes were found between siblings in a single clutch.

RESUMO

Caridina biyiga sp. nov. is described from Leichhardt Springs, Kakadu National Park, Northern Territory, Australia, based on morphological and molecular data. The new species is highly distinctive among its congeners in having the dactylus of pereiopod 5 similar to the dactyli of pereiopods 3-4 and lacking the comb-like row of spiniform setae typical of the genus. The branchial formula is also distinctive for the genus in lacking an arthrobranch at the base of pereiopod 1 and in having a vestigial epipod on maxilliped 1.                Despite the distinctive morphology of the new species, the molecular data did not provide strong support for the recognition of a new genus. Phylogenetic analyses of Australian Caridina using the mitochondrial 16S rDNA gene fragment placed the new species in a well-supported clade containing at least one typical species of Caridina. Within this clade, referred to as the 'thermophila' group, Kimura 2-parameter (K2P) genetic distances of 16S rDNA between the new species and sister taxa ranged from 5.1-6.0%. Analyses using the mitochondrial 3' COI gene fragment from species of the 'thermophila' group yielded K2P genetic distances between the new species and its sister taxa ranging from 10.4-15.1%.                A preliminary illustrated key to Northern Territory Caridina is provided. The conservation significance of Leichhardt Springs and its aquatic fauna are also briefly discussed.

RESUMO

In the 3-year study, heavy metals mobility factors for soils of public playgrounds within Owerri metropolis were correlated with soil particle size. Such studies could develop a body of knowledge that could enable detection and quantification of potential risk of metals to children from playground soil without actually involving children. Calculated values of mobility factors were subjected statistical treatment and to obtain descriptive statistics. Regression analysis of mobility factors and particle size were determined. Copper and zinc were most mobile elements, while cobalt was least mobile. Result showed that clay particle size had strong influence on mobility factors. The significance of this study is that recent estimation of mobility factors of metals are used to expand its possible understanding and application to fundamental and practical problems of ecotoxicology of metals which could reflect metals potentials to cause harm thereby permitting the evaluation of metals toxicity without direct involvement of children.

RESUMO

Previous studies on leaf-tailed geckos of the genus Uroplatus identified a lineage from the Ankarana karst massif in northern Madagascar as genetically highly divergent, but only fragmentary information was available on these geckos. Here, we provide an integrative analysis based on molecular and morphological data, including a newly collected specimen from this locality. Phylogenetic analysis placed the Ankarana lineage sister to U. ebenaui, but with a surprisingly high genetic divergence of over 19% uncorrected pairwise distance in the mitochondrial 16S rRNA gene. We formally describe the Ankarana lineage as Uroplatus fetsy sp. nov. and provide new information on the distribution and genetic differentiation of its sister species, Uroplatus ebenaui. Based on DNA sequences of newly examined samples this latter species is confirmed as widespread, ranging from low-elevation dry forests from Beanka in western Madagascar to Forêt d'Ambre and Analalava/Fanambana in northern Madagascar, and thus far has not been found in the Ankarana Massif, where U. fetsy occurs.

RESUMO

A list of 60 species of the Tettigoniidae (Orthoptera) recorded from Gorongosa National Park and provinces Sofala and Manica in central Mozambique is provided and their natural history is discussed. Of these, 58 species are illustrated and bioacoustic data are presented for 47 species. Two new genera and 9 new species are described: Gorongosa carri gen. et sp. n., Ovonotus abreuae gen. et sp. n., Afroagraecia muagurai sp. n., Enyaliopsis iaculator sp. n., Eurycorypha parkeri sp. n., Eurycorypha stalmansi sp. n., Eulioptera carolli sp. n., Eulioptera mutembai sp. n., and Parpyrrhicia guytonae sp. n. Four species of Ruspolia are recognized as potentially new and their bioacoustic data are presented. Pseudorhynchus pungens meridionalis Ragge, 1969 is synonymized with Pseudorhynchus pungens pungens (Schaum, 1853); Angustithorax spiniger Massa, 2015 is synonymized with Oxyecous magnus Ragge, 1956; and the synonymy of Lanista africana (Walker, 1870) with Lanista annulicornis (Walker, 1869) is reversed. Two species, G. carri and O. abreuae, appear to be endemic to Mt. Gorongosa and 24 species are recorded for the first time from Mozambique.

RESUMO

A new thelastomatid species, Desmicola lamdongensis sp. n. from the hindgut of Panesthiinae cockroaches collected in Bi Doup-Nui Ba National Park, Vietnam is described and illustrated. Males of the new species are characterized by seven to eight modified ventrally projected cuticular annuli on the posterior third of body and the straight spicule with a pointed distal tip; females are distinguished by the presence of tiny circular protrusions on the lip surface, three setiform sensilla as interlabial formations, horseshoe-shaped amphids and smooth oval egg-shells. D. lamdongensis sp. n. differs from the rest of Desmicola species in having males with ventrally projected cuticular annuli on the posterior body third vs. semispherical ventral cuticular protuberance. Similarly to females of other species of the genus, females of D. lamdongensis sp. n. possess a seminal receptacle only on the posterior branch of the reproductive system that allows them to produce a mixture of fertilized and non-fertilized eggs among their progeny. A key to species of Desmicola based on females is given. Posterovulva danieli Spiridonov Ivanova, 1998 is regarded as D. danieli n. comb. in accordance with the latest revision of the genus (Adamson Van Waerebeke 1992).

RESUMO

Heteragrion denisye sp. nov. (Zygoptera: Heteragrionidae) is described and diagnosed on specimens collected near a Vereda (i.e. palm swamp) area of the National Park of Serra da Canastra, Minas Gerais, Brazil (-20.2323, -46.6085, 1305 m, 25 x 2018, Vilela, Koroiva, Nobrega Lera leg.). This species is unique within the genus and it is easily distinguished from congeners due to its blue coloration pattern and cerci morphology, which is robust and presents a reduced apical portion, longer on most Heteragrion species.

RESUMO

Public parks are leisure environments widely used by both, adults and children, often accompained by their pets. Soil contamination of these environments by enteric viruses and intestinal parasites occurs through these animals feces. The aim of this work was to detect Carnivore protoparvovirus 1 (CPV-1) and different species of Mastadenovirus in soils samples from a park located in a medium-sized city in Brazil and evaluate the presence of helminth eggs and larvae in 18 points of a public park soil samples, as well as feces found on this site during six months. Parasitological analyzes were conducted through flotation and sedimentation techniques, and polymerase chain reaction (PCR) was used for viral detection. Of the 216 soil and 16 feces samples, 49% (106/216) and 12% (2/16) were positivefor nematodes larvae, respectively, through sedimentation techniques. Toxocara spp eggs were found in one soil sample and one feces sample, Trichuris spp eggs were found in only one feces sample and Hookworms eggs were found in four soil samples. After reconstruction work in the streets near the park, 30% (64/216) of the samples were positive for Human Mastadenovirus C (HAdV-C), 1.4% (3/216) for HAdV-E and 0.4% (1/216) for Canine Mastadenovirus A (CAdV-A). The parasitic forms found in this study have demonstrated that the contamination of the park's soil pose a threat to human and animal health. This was the first study to report the presence of HAdVs and CAdVs in soil samples.

RESUMO

RATIONALE: Recently, commercial indoor trampoline parks have been opened around the globe, and both the number of venues and the park users are increasing. Academic literatures have largely focused on home trampoline related injuries, and less is known about the injuries associated with trampoline parks due to the limited number of studies or cases reported. In this report, we present a complete spinal cord injury sustained at a commercial indoor trampoline park. PATIENT CONCERNS: A 26-year old male developed tetraplegia after plainly jumping on the trampolines and diving into one of the foam pits head first. DIAGNOSIS: C-spine CT revealed bilateral interfacetal dislocation on C6-7, and his C-spine MRI showed anterior translational injury at C6-7 with severe cord encroachment and complete discoligamentous complex disruption. He was diagnosed with complete spinal cord injury. INTERVENTIONS: The patient underwent 30 minutes each of physical therapy and occupational therapy twice a day for a total of 25 days of in-patient rehabilitation. Interventions included tilt table, passive range of motion exercises, functional electrical stimulation, sitting balance training, upper extremity strengthening exercise, and hand manipulation exercises. OUTCOME: Despite intensive rehabilitation and the patient's good spirit, there was no functional change in all physical examinations between evaluations at initial and at discharge. LESSONS: In conclusion, we aim to alert the risks associated with improper use of trampolines, promote safer entertainment environment, and aid in developing mandatory safety measures. We hope to alert the risks associated with improper use of trampolines, promote safer entertainment environment, and aid in developing mandatory safety measures.

RESUMO

Andaeschna is a small and poorly known genus of dragonflies that inhabits the Andes, from Venezuela to northwestern Argentina. Here we describe Andaeschna occidentalis sp. nov., first species of the genus recorded in the Western Andes, specifically from the Tatamá National Park in Colombia. Males of this species can be differentiated from the other four species in the genus by the unique shape of the distal segment of the vesica spermalis. Likewise, females can be distinguished by their smaller and broader cerci (slightly shorter than S9) and its subquadrate point. The discovery of this beautiful species expands the range of the genus, previously known only in the Eastern Andes.
