Relatively little is known about cetaceans in São Tomé and Príncipe and in recent years, some episodes of cetacean bycatch and human consumption have been described. Aiming to provide insight into the reliance upon cetaceans as a source of meat, we present findings from complementary studies conducted in the islands of São Tomé and Príncipe from 2012 to 2021. Based on interviews with local residents, we assessed the prevalence of human consumption of cetaceans and identified potential sociodemographic drivers. This study provides the first comprehensive assessment of harvest (direct remove or incidental take) and consumption of cetaceans (mainly the family Delphinidae) in the country. These findings will be useful in the development of regional conservation measures and contribute to our understanding of anthropogenic activities affecting cetacean populations in the Gulf of Guinea.

The monk parakeet, Myiopsitta monachus, is a species of parrot that is native to South America. By 2016 it had become invasive in Mexico and its populations have since increased dramatically, particularly in urban areas. It is currently difficult to predict whether it will expand into non–urban areas of the country. The aim of this work was to assess the risk of invasion of this parakeet into the Natural Protected Areas (NPAs) of Mexico, where interaction with the native parrots is worrisome due to the aggressive nature of this parakeet. Using potential distribution models we evaluated this risk using MaxEnt. We performed a functional analysis of all native parrots of Mexico and M. monachus seeking possible competition or displacement of the species. According to the MaxEnt model, the Biosphere Reserve Tehuacán–Cuicatlán is the NPA with the highest risk of such invasion (~42 % of its area presents climatically suitable values ≥ 0.75). The functional trait assessment revealed that the barred parakeet, Bolborhynchus lineola, is the species most similar (97 %) to the invasive monk parakeet. It is naturally distributed in the Biosphere Reserve of Tehuacán–Cuicatlán and, from all functional traits considered, differs only in nesting type. This study shows the potential risk that the invasive monk parakeet represents in Mexican NPAs, and emphasizes the need for effective actions in order to avoid further potential invasions and expansions of the species occur across Mexico.

Research on urban biodiversity has primarily addressed the effects of urbanization and human activity synergistically as it has been virtually impossible to dissociate their impact on city wildlife. However, the anthropause resulting from COVID–19 lockdowns provided an unprecedented scenario to study the relative role of human activity on avian communities. Here we provide evidence of the relationships between human activity and bird species richness in urban areas of Colombia during its strict and subsequent relaxed lockdowns. Once the strict lockdown was lifted and human activity increased, avian species richness decreased by 32 % in 46 % of our sampling sites. Although the strict lockdown lasted only six weeks, local assemblages (mainly from low–intensity urbanization peri–urban sites) swiftly became more diverse. Our findings highlight the importance of taking human activity into account when planning cities, with important focus on greenspaces, if our aim is to conserve and enhance urban biodiversity. Such plans will require not only the cooperation of local governments but also greater awareness among the local population regarding the importance of creating livable, healthy, biodiverse, and resilient cities.

Population and community dynamics of butterflies are relatively well known in Europe thanks to citizen science and academic efforts to cover large spatio–temporal scales. However, there are still gaps of knowledge about which life–history traits have a large influence on the dynamics of particular species and the ecological factors that influence those traits. We conducted a capture–recapture demographic study on the comma butterfly Polygonia c–album in a high mountain deciduous forest. We estimated daily survival in breeding adults caught while foraging on thistles and we calculated the probability of dispersal between two close sites. Thistle growth was enhanced by nitrification in cattle grazing in the study area. Local survival was higher for males (0.920, 95 % CI: 0.851–0.959) than for females (0.869, 95 % CI: 0.799–0.917). Short–range dispersal mostly occurred in absence of wind. Light winds and high levels of solar radiation likely enhanced foraging activity. In contrast with findings in most butterfly demographic studies, recapture rates were significantly higher in females than in males, likely due to the latter moving each afternoon to establish territories along sunny forest edges away from the foraging habitat. Further demographic studies are needed to assess the effects of climate stochasticity and habitat transformation caused by changes in extensive cattle grazing on the population dynamics of the comma butterfly.

In this paper we explore the usefulness of MaxEnt to predict the most suitable areas for a wildlife species, the Iberian ibex (Capra pyrenaica). For two decades (1990–2010), the species was established in a small part of the National Park Sierra de Guadarrama (Spain) and there has been a process of expansion to other areas of this protected area since 2010. However, almost two decades have elapsed since the modeling methods (MaxEnt) were proposed and no studies have tested their effectiveness using real distribution data, i.e. data from past predictions, to see if they fit the current distribution. We generated a model with presence– only data from 2007 and verified accuracy from 2017 data concerning real presence. Our results show a relationship between models and the species' current presence. The generated model can be useful to define the preferred locations of the species. We detected several differences between males and females of the species. This work not only shows the importance of selecting climatic and ecological variables for the construction of models but also indicates that they must be adjusted, at least for some species, to each sex and period of the year.

Neocordulia is a Neotropical genus with 16 species distributed in the South and Central Americas. To date, only seven larvae of this genus have been described. Here we describe the final instar larva of Neocordulia volxemi (Selys, 1874), collected in the Environmental Protection Area of the Uberaba River Basin in the State of Minas Gerais, Brazil. The metallic–green adults were found flying in a forested area in a Conservation Unit, while the larvae were found in a waterfall and surrounding rocky walls. The Cerrado remnant area is currently threatened by degraded pastures and increasing areas of monoculture agriculture.

Animal behaviour is potentially a mechanism of individual diet specialization. To explore this possibility we assessed exploratory behaviour (EB) and foraging data for a population of blue tits Cyanistes caeruleus. Our results suggest that: 1) foraging differs between sexes; 2) the prey type selected by females depends on the provisioning rates of their mate, and adjustment of this prey-choice differs between EB phenotypes; and 3) foraging behaviour in males shows a trend towards linkage to their EB phenotype, with faster-exploring males obtaining marginally larger caterpillars but provisioning less frequently than slower-exploring males. Lastly, environmental variables contributed substantially to the diet composition of offspring. For this reason, we cannot suggest that EB dominates, but it may contribute to a diet specialization process in our study population.

As the transformation of natural habitats into urban environments increases, some species, such as hedgehogs, are able to adapt and thrive. Six hedgehogs, three males and three females, were tagged with radio–transmitters and tracked for three nights in the University of Alicante campus to study the effect of sex on their home range size, distance travelled per night, and nocturnal activity pattern. Time invested in several activities was also analyzed. Males showed larger home ranges than females (mean ± SD) (♂: 27.7 ha ± 19.2; ♀: 5.5 ha ± 3.4) and travelled longer distances per night (mean ♂: 1077 m ± 251.18; ♀: 504 m ± 156.37). The rhythm of nocturnal activity showed a bimodal pattern but differed between sexes. Males tended to be on the move significantly more often than females (♂: 38.7 %; ♀: 24.8 %) while females foraged more often than males (♂: 1.4 %; ♀: 9.2 %).

Brongersma’s toad Barbarophryne brongersmai is known in the southern Moroccan Atlantic coast, in the Anti–Atlas, in the arid plain of Marrakech, and in several localities in North–western Algeria. However, its distribution in Morocco is far from clear and its range is not well known. We report a new record of B. brongersmai in Morocco, in the region of the central High Atlas. The habitat type in this region is different from areas where the species has been observed previously. It consists of temporary ponds, located between rock outcrops and filled by stormy rains or snow during the winter. We recommend conducting surveys to collect additional information about this toad in other Moroccan regions, such as in the Middle Atlas where suitable conditions for this species may exist.

The diet of a potentially omnivorous coastal shark species, the bonnethead (Sphyrna tiburo), was examined in the western Atlantic along the coast of the southeastern United States. A total of 423 stomachs collected from Texas, Alabama, Florida and South Carolina were analyzed using standardized stomach content analysis methods. The diet was dominated by crabs, primarily portunids (Callinectes spp.), across the geographical range analyzed, though the relative importance of crabs varied between regions. Ontogenetic shifts in diet were not observed throughout the region studied. Female and male bonnetheads in South Carolina displayed different diets, particularly in the amount of portunid crabs consumed, with a higher proportion ingested by females. Bonnetheads consumed limited amounts of seagrasses in all regions except in South Carolina, where they occupy habitats without seagrasses in marsh dominated bays and estuaries. This finding indicates that, at least seasonally, seagrasses are not an essential part of the diet of this shark species and may only occur in stomachs as accidental ingestion.

The diet was dominated by crabs, primarily portunids (Callinectes spp.), across the geographical range analyzed, though the relative importance of crabs varied between regions. Ontogenetic shifts in diet were not observed throughout the region studied. Female and male bonnetheads in South Carolina displayed different diets, particularly in the amount of portunid crabs consumed, with a higher proportion ingested by females. Bonnetheads consumed limited amounts of seagrasses in all regions except in South Carolina, where they occupy habitats without seagrasses in marsh dominated bays and estuaries. This finding indicates that, at least seasonally, seagrasses are not an essential part of the diet of this shark species and may only occur in stomachs as accidental ingestion.","PeriodicalId":49107,"journal":{"name":"Animal Biodiversity and Conservation","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41846392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
