Opportunities for the conservation of migratory birds to benefit threatened resident vertebrates in the Neotropics. [PDF]

J Appl Ecol, 2022
Funding and effort for migratory bird conservation also has potential to benefit threatened resident vertebrates in the Neotropics. Our study highlights how novel, high‐resolution information on species distributions and risk of forest loss can be integrated to identify priority areas for the two groups at regional and landscape scales.

Establishment, Characterization, and Cryopreservation of Feather Follicle Fibroblast Lines From Hyacinth Macaw (Anodorhynchus hyacinthinus). [PDF]

Cell Biol Int
ABSTRACT Cryopreservation, biobanking, and in vitro propagation of cells from endangered species represent key strategies for advancing biodiversity conservation. The Hyacinth Macaw (Anodorhynchus hyacinthinus), a flagship avian species of the Brazilian Pantanal, is among the critically vulnerable taxa that stand to benefit significantly from such ...

Linking ecological niche models and common garden experiments to predict phenotypic differentiation in stressful environments: Assessing the adaptive value of marginal populations in an alpine plant. [PDF]

Glob Chang Biol, 2022
Environmental variation within a species’ range can create contrasting selective pressures, leading to divergent selection and novel adaptations. Here, we explored the use of ecological niche models (ENMs) linked with common garden experiments to predict and test for genetically determined phenotypic differentiation related to contrasting environmental

Habitat Changes at the Local Scale Have Major Impacts on Waterfowl Populations Across a Migratory Flyway. [PDF]

Glob Chang Biol
Migratory waterbirds are declining worldwide due to habitat loss, but not much is known about how the loss of specific wetlands can affect waterbird populations at the biogeographical scale. To investigate that, we used the Guadalquivir Marshes (SW Spain) as a case study and combined 38 years of waterfowl winter counts with environmental and remote ...

Morphological and ultrastructural characterization of neurospheres spontaneously generated in the culture from sheep ovarian cortical cells

The Anatomical Record, Volume 305, Issue 9, Page 2265-2280, September 2022., 2022
Abstract Neurospheres (NS) derived from adult stem cells of non‐neural tissues represent a promising source of neural stem cells (NSCs) and neural progenitor cells (NPCs) for autologous cell therapy. Knowing the fine structure of NS cells is essential for characterizing them during differentiation or oncogenic transformation.

Stable isotopes reveal seasonal dietary responses to agroforestry in a venomous mammal, the Hispaniolan solenodon (Solenodon paradoxus)

Ecology and Evolution, Volume 12, Issue 3, March 2022., 2022
The Hispaniolan Solenodon (Solenodon paradoxus) is a venomous mammal endemic to the Dominican Republic and Haiti. Stable isotope analysis of fecal samples, with a historical hair reference, show how solenodons may alter their resource use in response to agroforestry and associated land cover changes across seasons.
