RESUMO

Mango anthracnose, caused by Colletotrichum spp., is the most significant disease of mango (Mangifera indica L.) in almost all production areas around the world. In Mexico, mango anthracnose has only been attributed to C. asianum and C. gloeosporioides. The aims of this study were to identify the Colletotrichum species associated with mango anthracnose symptoms in Mexico by phylogenetic inference using the ApMat marker, to determine the distribution of these species, and to test their pathogenicity and virulence on mango fruits. Surveys were carried out from 2010 to 2012 in 59 commercial orchards in the major mango growing states of Mexico, and a total of 118 isolates were obtained from leaves, twigs, and fruits with typical anthracnose symptoms. All isolates were tentatively identified in the C. gloeosporioides species complex based on morphological and cultural characteristics. The Bayesian inference phylogenetic tree generated with Apn2/MAT intergenic spacer sequences of 59 isolates (one per orchard) revealed that C. alienum, C. asianum, C. fructicola, C. siamense, and C. tropicale were associated with symptoms of mango anthracnose. In this study, C. alienum, C. fructicola, C. siamense, and C. tropicale are reported for the first time in association with mango tissues in Mexico. This study represents the first report of C. alienum causing mango anthracnose worldwide. The distribution of Colletotrichum species varied among the mango growing states from Mexico. Chiapas was the only state in which all five species were found. Pathogenicity tests on mango fruit cultivar Manila showed that all Colletotrichum species from this study could induce anthracnose lesions. However, differences in virulence were evident among species. C. siamense and C. asianum were the most virulent, whereas C. alienum and C. fructicola were considered the least virulent species.

RESUMO

A newly discovered nickel (Ni) hyperaccumulator plant, Breynia cernua (Phyllanthaceae) from the nickeliferous laterites of Acoje, Zambales, has elevated Ni concentrations. Its computed bioaccumulation factor is 1.7 and the translocation factor is 4.6. Leaf tissues which contain the highest Ni concentrations were analyzed using optical microscopy and Scanning Electron Microscopy with Energy-Dispersive X-ray (SEM/EDX). The results indicated that most of the Ni are stored in the epidermal cells of the leaves, followed by the mesophyll cells then the vascular bundles. The accumulation of Ni found in the subcellular locations, probably in the vacuoles, may prevent phytotoxicity that could affect the normal function of other cellular structures. A possible resistance mechanism through strain avoidance towards Ni accumulation makes B. cernua capable of tolerating elevated Ni concentrations in its tissues. The tolerance of B. cernua to Ni phytotoxicity suggests possible applications of this hyperaccumulator plant in phytoextraction technology.

RESUMO

'Managed retreat' is gaining considerable attention as part of megacities' climate change adaptation and resilience enhancement toolkits, and as a policy option for disaster risk reduction in coastal regions. The overarching objective of managed retreat is to reduce the exposure of people and assets to flooding, storm surges and sea level rise by retreating from these threats in a planned fashion. Managed retreat is one of four main options covered in the 'PARA' (protect/accommodate/retreat/avoid) framework explained in this paper, which can be used to enhance resilience in coastal megacities. In this paper, qualitative research methods were used to collect primary data on the feasibility of using managed retreat for two case study coastal megacities: Manila, Philippines, and Vancouver, Canada. Both case studies review the risk context of each city, local climate change adaptation/disaster risk reduction (CCA/DRR) policies linked to managed retreat, examples of managed retreat practice, and barriers to managed retreat identified through primary or secondary data analysis. Comparisons between the two cases are then carried out, and similarities and differences are highlighted. The paper concludes by suggesting possible means by which barriers to managed retreat might be overcome.

RESUMO

BACKGROUND: Previous literature suggests that higher ambient temperature may play a role in increasing the risk of suicide. However, no multi-country study has explored the shape of the association and the role of moderate and extreme heat across different locations. OBJECTIVES: We examined the short-term temperature-suicide relationship using daily time-series data collected for 341 locations in 12 countries for periods ranging from 4 to 40 y. METHODS: We conducted a two-stage meta-analysis. First, we performed location-specific time-stratified case-crossover analyses to examine the temperature-suicide association for each location. Then, we used a multivariate meta-regression to combine the location-specific lag-cumulative nonlinear associations across all locations and by country. RESULTS: A total of 1,320,148 suicides were included in this study. Higher ambient temperature was associated with an increased risk of suicide in general, and we observed a nonlinear association (inverted J-shaped curve) with the highest risk at 27°C. The relative risk (RR) for the highest risk was 1.33 (95% CI: 1.30, 1.36) compared with the risk at the first percentile. Country-specific results showed that the nonlinear associations were more obvious in northeast Asia (Japan, South Korea, and Taiwan). The temperature with the highest risk of suicide ranged from the 87th to 88th percentiles in the northeast Asian countries, whereas this value was the 99th percentile in Western countries (Canada, Spain, Switzerland, the UK, and the United States) and South Africa, where nearly linear associations were estimated. The country-specific RRs ranged from 1.31 (95% CI: 1.19, 1.44) in the United States to 1.65 (95% CI: 1.40, 1.93) in Taiwan, excluding countries where the results were substantially uncertain. DISCUSSION: Our findings showed that the risk of suicide increased with increasing ambient temperature in many countries, but to varying extents and not necessarily linearly. This temperature-suicide association should be interpreted cautiously, and further evidence of the relationship and modifying factors is needed. https://doi.org/10.1289/EHP4898.

RESUMO

Siargao Island is located on the southeastern part of the Philippines. We have very little knowledge on the Orthoptera from this island which is covered with forest over limestone, open vegetation, and mangrove, despite being designated as one of the terrestrial Key Biodiversity Areas (KBAs) in the Philippines. We conducted surveys in 2018 to search for orthopterans. In total, thirty-seven species from 34 genera were found. Seventeen species are recorded in Siargao Island for the first time, representing 45.9% of all collected species, thus, validating that orthopterans in the island are indeed overlooked. Out of the 37 species, 21 of these are endemic to the Philippines and 9 are endemic to Siargao Island, hence suggesting that species on the island can be biologically significant..                We also observed that a huge proportion of the species in Siargao Island are fully winged and capable of flight, but most species are small sized. We also provide taxonomic notes and illustrations, including descriptions of the male Segestidea punctipennis Bolívar, 1903 and female Eumecopoda reducta Hebard, 1922 for the first time. We inferred that species from Siargao Island are closely associated with Sundaland and for within Philippines, Mindanao and Luzon.

RESUMO

Siccia yvonneae Kühne, 2007 described as member of Lithosiini (Erebidae, Arctiinae) is transferred in the present paper to the genus Meganola Dyar, 1898 of Nolini (Nolidae, Nolinae): Meganola yvonneae (Kühne, 2007), comb. nov. Meganola yvonneae is compared to M. conspicua Dyar, 1898 type species of the genus, to M. albula ([Denis Schiffermüller], 1775) a widespread Palaearctic species and to Manoba lithosiformis László, Ronkay Ronkay, 2014 described from the Philippines as an example of a Nolinae reminding of the general habitus of Siccia from SE Asia. The adult and genitalia of the Lithosiini Siccia caffra Walker, 1854 are also figured for comparative purposes.

RESUMO

Sycoracinae is a subfamily of Psychodidae, currently with 45 extant species (Curler Jacobson 2012; Santos et al. 2013) classified in three genera: Sycorax Haliday in Curtis; Parasycorax Duckhouse and Aposycorax Duckhouse (Duckhouse 1972; Young 1979). Sycorax comprises a majority of this diversity with 40 extant species, 15 of which are recorded from the Neotropical region (Curler Jacobson 2012; Santos et al. 2013). Four fossil species of Sycorax have also been described (Curler Jacobson 2012), including one from middle Miocene Amazonian amber (Petrulevicius et al. 2011). In contrast, Parasycorax includes only four extant species; three from South America and one from the Philippines (Santos et al. 2009) and a fossil species from Cretaceous Burmese amber (Stebner et al. 2015). Here we describe a new species of Parasycorax and provide an updated key to males of all extant and fossil species of the genus. In addition, Sycorax bravoi Santos, Ferreira Falqueto and Sycorax espiritosantensis Santos Bravo are recorded for Santa Catarina State, southern Brazil.

RESUMO

The Agrilus vittatus species-group comprising fifteen species from the Oriental region is defined and revised. A key to species is provided and complemented with illustrations of habitus and genitalia. Five new species are described: Agrilus acacivorus sp. nov. (Myanmar); A. albizivorus sp. nov. (North India, Nepal); A. coco sp. nov. (Philippines); A. monadikos sp. nov. (Laos) and A. occultus sp. nov. (Laos, Thailand). Seven new junior subjective synonyms are proposed for following taxa: Agrilus babaulti Théry, 1930 (= bonadonai Descarpentries Villiers, 1963 syn.nov.); A. terraereginae Blackburn, 1892 (= deerratus Curletti, 2006 syn.nov.) and A. viridicupreus Saunders, 1866 (= cylindratus Kerremans, 1896 syn.nov., = albizziae Fisher, 1935 syn.nov., = javicola Fisher, 1935 syn.nov., = cariosulus Obenberger, 1935 syn.nov., = theodasae Baudon, 1968 syn.nov.).

RESUMO

A new species of Trimma, T. wangunui, is described from three localities in the western Pacific (Papua New Guinea, Timor-Leste and the Philippines). It belongs to a small group of species with scales in the predorsal midline, no scales on the cheek or the opercle, all pectoral fin rays unbranched, and a branched fifth pelvic fin ray. It differs from other species in this group in having an elongate second spine of the first dorsal fin which reaches to the bases of the 2nd-8th second dorsal-fin rays when adpressed, in having yellow bars on the head, and in the presence of vertically elongate yellow spots on a brown body when freshly collected.

RESUMO

Two new species of black flies, Simulium mainitense and S. tukurongense, are described from Palawan, the Philippines. Both species are placed in the Simulium nitidithorax subgroup of the Simulium tuberosum species-group of Simulium (Simulium). They are characterized by the female sensory vesicle of medium length, pupal thorax covered with round tubercles, and anterodorsal trichomes on the pupal thorax longer than frontal trichomes. This combination of characters separates these two new species from S. quasifrenum Delfinado, the only previously known member of the S. nitidithorax subgroup from Palawan, and nine other related species from Sabah, Sarawak, Peninsular Malaysia and India. Simulium mainitense sp. nov. is distinguished from S. tukurongense sp. nov. in the female by the somewhat larger body size, and greater length ratio of the labrum against the clypeus; and in the pupa by the much longer gill filaments.

RESUMO

The genus Theopea Baly, 1864 is redefined. Seventeen species from Sundaland and the Philippines are recognized and classified into four species groups (including seven new species): T. impressa (Fabricius, 1801), T. longicollis (Jacoby, 1896), T. louwerensi Jolivet, 1951, T. lunduensis Mohamedsaid, 1998, T. chungi sp. nov. in the T. impressa group; T. flavipalpis Laboissère, 1940, T. guoi sp. nov., T. lui sp. nov., T. sabahensis sp. nov. in the T. flavipalpis group; T. elegantula Baly, 1864, T. pulchella Baly, 1864, T. fairmairei Duvivier, 1885, T. kedenburgi Weise, 1922, T. houjayi sp. nov., T. tsoui sp. nov., T. yuae sp. nov. in the T. pulchella group; and T. costata (Allard, 1889) in the T. costata group. The following new synonyms are established: Theopea pulchella Baly, 1864 = T. nigricollis Jacoby, 1892 syn. nov.; Theopea impressa (Fabricius, 1801) = T. impressa flavicornis Laboissère, 1940 syn. nov. and T. impressa malaccana Laboissère, 1940 syn. nov.; T. lunduensis Mohamedsaid, 1998 = T. sepilokensis Mohamedsaid, 2000 syn. nov. Lectotypes are designated for Crioceris impressa Fabricius, 1801, Ozomena longicollis Jacoby, 1896, Theopea elegantula Baly, 1864, T. fairmairei Duvivier, 1885, T. nigricollis Jacoby, 1892, and T. pulchella Baly, 1864. Theopea obliterata Jacoby, 1884, T. variabilis (Jacoby, 1887), T. incostata (Allard, 1889), T. clypeata Jacoby, 1896, T. modiglianii Jacoby, 1896, T. dohrni (Jacoby, 1899), T. viridipennis (Jacoby, 1899), and T. weberi (Weise, 1913) are removed from Theopea and regarded as species incertae sedis.

RESUMO

A new species of the Marphysa sanguinea group, M. iloiloensis n. sp. (Annelida: Eunicida: Eunicidae), is described from the Marine Annelids Hatchery of the Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC- AQD), Iloilo Province, Philippines. It represents the first record of this group in the Philippines. The new species is most similar morphologically to M. hongkongensa Wang, Zhang Qiu, 2018, but can be distinguished from it by having fewer branchial filaments, a pair of faint eyes (absent in M. hongkongensa), and in slight differences in jaw morphology and chaetation. The embryos of the new species develop inside a jelly cocoon attached to the entrance of the adult burrow; this is the first time that egg-containing cocoons have been found in any species of the sanguinea-group. Phylogenetic analysis based on the mitochondrial gene cytochrome c oxidase subunit I (COI) revealed that Marphysa iloiloensis n. sp. is genetically distinct from all other analysed Marphysa species and forms a sister group to M. hongkongensa. A revised identification key to members of the sanguinea-group in Southeast Asia is provided.

RESUMO

The taxonomy of the Sundathelphusa philippina (von Martens, 1868) species group (Brachyura; Gecarcinucidae) from the Philippines is revised, and two new species are described. Sundathelphusa philippina sensu stricto is here restricted to the Bicol Peninsula of southern Luzon, and to the islands of Samar and Leyte. It is one of the largest freshwater crabs in the archipelago, reaching carapace widths of more than 53 mm. Sundathelphusa cebu sp. nov. from Cebu Island is superficially similar to S. philippina in morphology but can be separated by a suite of carapace characters. Sundathelphusa quirino sp. nov. from northern Luzon is the most distinct of the three taxa, with a distinctly more swollen carapace, relatively wider male pleon and a straighter male first gonopod. Sundathelphusa spelaeophila Stasolla, Abbarchi Innocenti, 2015, is also shown to be a junior synonym of S. philippina sensu stricto.

RESUMO

Pachyrhynchus phaleratus Waterhouse, 1841, an entimine weevil belonging to the tribe Pachyrhynchini Schoenherr, 1826, was originally described from "the Philippine Islands", based on material collected by Hugh Cuming (Waterhouse 1841). The precise type locality of this species is unknown, but Schultze (1923) recorded it from Catanduanes Island in the Bicol region of Luzon, Philippines.
