Proliferation of differentiated glial cells in the brain stem

open access: yesBrazilian Journal of Medical and Biological Research, 1998
Classical studies of macroglial proliferation in muride rodents have provided conflicting evidence concerning the proliferating capabilities of oligodendrocytes and microglia.

Designing for biodiversity data in place: Species, encounters, and interfaces

open access: yesPeople and Nature, EarlyView.
Abstract Species occurrence data, which records the presence of an organism at a point in space and time, is central to environmental science and its opening up to new forms of participation such as citizen science. Such data are increasingly aggregated and mobilised, reaching diverse audiences.

Eosinophilic Sialodochitis Identified in Duct Remnant After Submandibular Gland Resection

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Eosinophilic sialodochitis (ES) is an increasingly recognized cause of recurrent sialadenitis but likely remains underdiagnosed as it is commonly considered to be nonspecific chronic sialadenitis. ES is likely increasing in prevalence in association with the growing number of allergic diseases and should be considered in patients presenting ...

Anatomy of the heart and coronary blood supply of the white-eared opossum (Didelphis albiventris) [PDF]

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia
Although the white-eared opossum is frequently observed in both rural and urban environments, there is little anatomical knowledge about this marsupial species. To our knowledge, there are no descriptions of its heart anatomy. Thus, the aim of this study

Assessing physiological, behavioral and movement responses to Suprelorin implant delivery methods in free‐ranging eastern grey kangaroos Macropus giganteus

open access: yesWildlife Biology, EarlyView.
Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

Fecal Glucocorticoid and Androgen Metabolites in Eastern Grey Kangaroos (Macropus giganteus) Following Environmental Relocation

open access: yesZoo Biology, EarlyView.
Fecal glucocorticoid (GCM) and androgen metabolite (AM) concentrations were monitored for 3 months following the relocation of three eastern gray kangaroos (Macropus giganteus) between zoological facilities. Both metabolites showed high concentrations during the early postrelocation period, followed by a rapid decline and stabilization, suggesting ...

Coat colour in marsupials: genetic variants at the ASIP locus determine grey and black fur of the brushtail possum

open access: yesRoyal Society Open Science
The possession of fur or hair is a defining characteristic of mammals and can occur in a variety of colours and patterns. While genetic determinants of coat colour are well described in eutherian ‘placental’ mammals, the other major mammalian infraclass,

Weathering the storm: Most maternal and environmental drivers of individual reproductive success do not scale up to population recruitment in a large herbivore

open access: yesJournal of Animal Ecology, EarlyView.
Using 18 years of data on eastern grey kangaroos, we show that drivers of individual reproductive success often do not scale up to population recruitment. Birth asynchrony could buffer population recruitment against environmental variability, such that variables affecting individual reproduction have little impact at the population level.

Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals

open access: yesIntegrative Zoology, EarlyView.
We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying
