Testicular Echobiometry and Sperm Characterization in Oncilla (Leopardus tigrinus) From the Caatinga Biome

Zoo Biology, EarlyView.
We describe testicular echobiometry and sperm characterization in oncilla (Leopardus tigrinus) from the Caatinga biome, Ceará, Brazil. ABSTRACT Among neotropical small felids, the Leopardus tigrinus is classified as vulnerable by the International Union for Conservation of Nature, but studies on reproductive morphology and physiology are scarce for ...

Banking Biodiversity: Ex Vivo Solutions for a Planet in Crisis

Zoo Biology, EarlyView.
Genetic diversity is being lost faster than it can be cataloged. Biobanking preserves cells, gametes, and DNA as recoverable material for future conservation use, and delivers most when collections are established proactively rather than deployed once populations are already critically depleted.
