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 ...

Ex Situ Conservation

2017
This chapter looks into ex situ conservation. It acknowledges that in situ conservation techniques might be needed if a successful ex situ conservation programme, which is termed reintroduction, is achieved. The chapter explores the subdivisions of ex situ conservation: intensive or general captive breeding programmes and gene banks.

Ex Situ Conservation

2019
This chapter focuses on ex situ (off-site) conservation, which is the protection and management of biodiversity in artificial, human-built environments. Indeed, ex situ conservation allows wild-caught individuals to be maintained under close human supervision in facilities like zoos, aquariums, botanical gardens, or arboretums.

The science and economics of ex situ plant conservation

Trends in Plant Science, 2009
Ex situ seed storage underpins global agriculture and food supplies and enables the conservation of thousands of wild species of plants within national and international facilities. As an insurance policy against extinction, ex situ seed conservation is estimated to cost as little as 1% of in situ conservation.

The Future of Ex Situ Conservation

2000
It is with great trepidation that we attempt in this final chapter to address what we believe may be the major issues that Ex Situ conservationists will be forced to confront and attempt to resolve in the next ten to fifty years, let alone the whole of the new millennium.

Ex Situ Conservation of Forage Legumes

2001
This chapter analyses progress and the current status of ex situ conservation of 739 species of 27 genera of forage legumes in relation to their natural distribution. Analysis is based on passport data of individual accessions. As such, the scope of the chapter is restricted to those collections for which the authors have been granted access to ...

Captive breeding and ex situ conservation

2013
Abstract Primates began the arduous journey out of their native countries and into captive collections in the late nineteenth century. However, their survival was severely limited by a lack of natural history knowledge and husbandry requirements. In the decades to follow, primate survivorship and propagation in zoos greatly increased. By
