Benchmarks defining high-quality sperm in the common marmoset (Callithrix jacchus).

Background: Common marmosets (Callithrix jacchus) are increasingly recognized as valuable nonhuman primates (NHPs) for biomedical research due to their small size and short reproductive cycle and lifespan relative to other NHP species. Maximizing the utility of captive research marmosets, including genetically manipulated animals, will require the use of assisted reproductive techniques (ART) including manipulation, storage, and sharing of marmoset sperm. Here, we identify characteristics of high-quality semen samples and validate a simple method for selecting high-quality sperm.

- Amyloidosis involves the aggregation of proteins into amyloid, leading to organ dysfunction, and has been studied in various animal species, but knowledge is limited compared to humans.
- Identifying the specific amyloid precursor proteins is crucial for diagnosing and understanding the disease's origins, with 42 proteins noted in humans and a few key ones in animals.
- Recent advancements in diagnostic techniques like immunohistochemistry and mass spectrometry have revealed new types of amyloidosis in animals, suggesting a genetic component and possible transmissibility in some cases.
Application of Reproductive Technologies to the Critically Endangered Baw Baw Frog, .

Reproductive technologies (RTs) can assist integrated conservation breeding programs to attain propagation targets and manage genetic diversity more effectively. While the application of RTs to enhance the conservation management of threatened amphibians has lagged behind that of other taxonomic groups, a recent surge in research is narrowing the divide. The present study reports on the first application of RTs (hormone-induced spawning, hormone-induced sperm-release, and sperm cryopreservation) to the critically endangered Baw Baw frog, .

Background: Agricultural and pastoral landscapes can provide important habitat for wildlife conservation, but sharing these landscapes with wildlife can create conflict that is costly and requires managing. Livestock predation is a good example of the challenges involving coexistence with wildlife across shared landscapes. Integrating new technology into agricultural practices could help minimize human-wildlife conflict.

Sound is a complex feature of all environments, but captive animals' soundscapes (acoustic scenes) have been studied far less than those of wild animals. Furthermore, research across farms, laboratories, pet shelters, and zoos tends to focus on just one aspect of environmental sound measurement: its pressure level or intensity (in decibels). We review the state of the art of captive animal acoustic research and contrast this to the wild, highlighting new opportunities for the former to learn from the latter.
