(Received 14 June 2019; accepted 23 September 2020) We examine notions of taxonomic 'impediment', 'gap', 'inflation' and 'anarchy', all which are increasingly prevalent in discussions the global biodiversity crisis. Following a critical analysis history those notions, we postulate that entire issue behind them resides deep philosophical deficiency general comprehension principles. In particular, there is profound "conceptual turbulence" knowledge flux between taxonomy conservation biology....
Is stability too revered in zoological nomenclature?Recently, the ICZN Commissioners (Ceríaco et al. 2023) issued a formal statement signalling their resistance to promoting replacement of specific epithets honouring historical figures who, for example, advocated racist and/or sexist views, or were otherwise associated with unethical behaviour.Before analysing logic position, we feel compelled comment on origin what believe be 'stability fixation' that forms backdrop most papers criticizing...
Glucocorticoids mediate physiological processes to obtain energy, presenting daily variation in basal levels that may be related behavioural activity pattern. Identification of plasticity the secretion these hormones is essential understand their effects on physiology and behaviour wild birds and, therefore, success natural or artificial environment. Serial endocrine evaluations are facilitated by implementing non-invasive methodologies minimize possible manipulation animal's variables....
Introduction: We analyzed the variation in age structure, sex ratio, proportion of reproductive individuals, and size at sexual maturity, litter a population sigmodont rodent Wiedomys pyrrhorhinos. compared observed distributions with monthly rainfall for same period, to identify period assess effects rains on structure during ensuing months. further our results patterns recovered from other documented outbreaks possible causes presumptive outbreak represented by this series. Methodology:...
Abstract To define the chances of a dispersed seed to produce new recruit, it is essential consider all stages dispersal process. Howler monkeys are recognized have positive impacts on forest regeneration, acting as primary dispersers. Furthermore, dung beetles attracted their feces protect seeds against predators, and provide better microenvironment for germination due removal fecal matter, burial, and/or by reducing spatial aggregation in clumps. Despite effects through defecation howler...
Abstract Habitat loss and fragmentation have been leading jaguars to constant conflicts with humans, as a result, jaguar populations declining over the last decades. Captive breeding is often tool for species conservation, it not different jaguars. However, success far from optimal due lack of basic knowledge about species’ reproductive biology. In present study, we assessed gonadal hormonal profiles natural oestral cycles puberty compared our data those other wild felids. We collected...
Abstract Rodents are notable for their unique life history traits that render a fast-breeding capacity. Their short generation times allow local adaptations to appear, and several studies have tried understand if—and how—geographical variables influence adaptation in traits. We compared demographic of the Neotropical cricetid Necromys lasiurus based on 7,400 museum specimens collected daily simultaneously over 5 years at sites Caatinga biogeographic domain subject heterogeneous geographic...
Abstract Disentangling the structure of plant–animal mutualisms shed light on how species are organized, and allow us to infer about resilience, specificity, ultimately consequences loss functions ecosystem. Here we gathered fruit–frugivore interactions for all major vertebrate taxa interacting with plants in two conservation states Brazilian Atlantic forest: a small patch continuous forest. Using network approach, identified individual roles played by vertebrates plants, as well most...
Hair is one widely used alternative matrix for endocrine studies. Not only can it maintain hormone content during storage long periods of time, but its collection also induces little to no stress. Noninvasive techniques have broadened the opportunities research, particularly regarding wild animals. Despite advantages, many sources variation may affect steroid concentration found in hair, such as body location harvested, fur color, reproductive status, and sex. Thus, domestic species, dog,...
Mammals are generally brown in colour, but recent publications showing that they may not be as uniform once assumed. Monotremes, marsupials, and a handful of eutherians reflect various colours when lit with UV light, mostly purple. Because these still scarce records, we aimed to explore reflectance among rodent genera, the most diverse mammalian group, group common records biofluorescence. Here report structures like nails quills reflected green, for it was faded. However, Hystrix,...
The Caatinga is an exclusively Brazilian biome, and the largest most biodiverse Seasonal Tropical Dry Forest in world. Despite that, mammalian fauna, especially small mammals, least studied of all biomes. In order to fill gaps provide detailed information on mammals (Didelphimorphia, Rodentia) we compiled reliable records focusing richness, composition some biometric data. These came from mammal collections, papers, theses, books, unpublished data, prioritizing with vouchers housed...
Abstract Background The advent of non‐invasive methods provides a powerful alternative to stress studies as the use stressful handling techniques is no longer needed. However, many factors influence hormone metabolism such sex, diet, and metabolic rate. Thus, validation should be species‐ matrix‐specific. Methods To assess response in brown howler monkeys Alouatta clamitans , we adopted an ACTH challenge test parallelism provide physiological laboratorial validation. Radioimmunoassay was...
The presence of humans frequently modifies the behavior animals, particularly their foraging patterns, compromising energetic demands. fiddler crab Leptuca leptodactyla inhabits mangroves with high degrees anthropogenic influence. Thus, we tested if populations living in highly anthropized respond differently from those more protected areas. We predict that individuals touristy areas will be tolerant to and resume activities sooner after disturbance. To do so, conducted an experiment...
