Distribution and changes in the sbGnRH system in Rastrelliger brachysoma males during the breeding season

open access: yesScientia Marina, 2021
Rastrelliger brachysoma is a mariculture candidate species, but reproduction in captive fish has been problematic. This report examines the difference in the HPG axis, the neuroendocrine system and the development of reproductive tissues between captive ...

Scent detection dogs as a novel method for oestrus detection in an endangered species, the Tasmanian devil (Sarcophilus harrisii)

open access: yesFrontiers in Veterinary Science, 2023
Captive breeding is a critical tool for conservation of endangered species. Identifying the correct time to pair males and females can be a major challenge for captive breeding programmes, with current methods often being invasive or slow. Detection dogs

Unique multiple paternity in the endangered big‐headed turtle (Platysternon megacephalum) in an ex situ population in South China

open access: yesEcology and Evolution, 2019
Understanding the mating system and reproductive strategies of an endangered species is critical to the success of captive breeding. The big‐headed turtle (Platysternon megacephalum) is one of the most threatened turtle species in the world.

The importance of regulatory compliance in wildlife captive breeding: Case study from deer captive breeding in Indonesia

open access: yes, 2022
Indonesia has five deer species that the Indonesian government protects. Among these deer, Javan deer (Rusa timorensis) and sambar deer (Rusa unicolor) have received conservation attention through captive breeding.

Insights into the successful breeding of Hawksbill sea turtles (Eretmochelys imbricata) from a long-term captive breeding program

open access: yes, 2020
Sea turtle populations are declining and evidence-based methods for supporting their populations are required. Captive breeding and release programs can be effective, offering the opportunity to supplement nature populations; however, sea turtles require

Conservation of the endangered Arctic fox in Norway - are successful reintroductions enough? [PDF]

open access: yes, 2022
Translocation of captive-bred animals has become a widespread conservation practice to counteract species extinctions. We analyse and discuss the apparent success and shortcomings of Arctic fox (Vulpes lagopus) reintroductions in alpine tundra areas of ...

A General and Efficient Framework for the Rapid Design of Miniaturized, Wideband, and High‐Bit RIS

open access: yesAdvanced Electronic Materials, EarlyView.
A general and efficient framework is proposed for the rapid design of high‐performance reconfigurable intelligent surfaces (RISs). This framework integrates advanced antenna design techniques and incorporates various load types, quantities, and values to achieve the design of high‐performance RISs.

Plasma metabolites reflect seasonally changing metabolic processes in a long-distance migrant shorebird (Calidris canutus) [PDF]

open access: yes, 2002
Migrant birds have tightly scheduled annual cycles consisting of several distinct life cycle (sub-)stages such as reproduction, migration, moult and overwintering, each of which have specific metabolic requirements (e.g., fattening during migration ...
