Data on the distribution and status of these species in the country is collated from museum specimens, published literature and reliable observations to provide a basis for future research. A hierarchical approach is taken towards types of record and maps are provided that distinguish these for all species. All three species remain common in the Chaco region west of the Paraguay River, and all are considered of Least Concern. However, this region is experiencing high levels of deforestation and data to assess the potential declines of the species is unavailable. The two species of procyonid are also widespread in the Oriental region, but the status of Conepatus chinga there is unclear. There are multiple reports from the Atlantic Forest region but documentation is limited to fecal molecular samples. Clarifying the distribution of that species in the Oriental region is a priority for research.","PeriodicalId":506977,"journal":{"name":"Natural History Sciences","volume":"304 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140719383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, in April and May of the years 2020-2023, a conspicuous contingent of Alosa fallax (Lacépède 1803) was reported. The frenetic behaviour of the individuals observed, some of which showed swollen bellies and considerable size, suggested that this watercourse may represent a potential new breeding station for this threatened migratory euryhaline fish species. The correct recognition of the sex of A. fallax in the field, problematic during the breeding season, is crucial for understanding its population structure as indicators of possible reproduction. To this end, statistical analysis (Mann-Whitney U-test) of 20 morphometric measurements made on individuals captured and subsequently released revealed significant differences between the sexes for seven morphometric characters, confirming a sex ratio compatible with reproduction. However, the presence of a transverse dam with no fish ladder and the dispersion of biocides from farmland in the final stretch may represent a serious threat to effective reproduction.","PeriodicalId":506977,"journal":{"name":"Natural History Sciences","volume":"591 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140718936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We describe for the first time the breeding biology and behaviour of the IUCN Near Threatened northern sooty woodpecker Mulleripicus funebris based on observations from a single active nest found in a standing dead Parkia timoriana tree at the Subic Watershed Forest Reserve, Zambales, Luzon, Philippines. The nest was observed from late February to May 2022 for a total of 63.7 hours. The cavity was 16.4 m from the ground and had opening dimensions (L x W) of 9.0 x 8.0 cm and a depth of 37.0 cm. Breeding of M. funebris lasted ≈76-83 days from nest excavation (≈27 days) to fledging. The brood size was two. Both parents were involved in nest building and chick-rearing activities. The male M. funebris contributed more hours during nest building and diurnal incubation whereas the female dominated feeding of nestlings and nest sanitation during the time of fledging. We recommend the retention of standing dead trees as nesting sites for woodpeckers and already existing holes for other cavity-nesting fauna.","PeriodicalId":506977,"journal":{"name":"Natural History Sciences","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140717920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
