Body size is key to many life-history processes, including reproduction. Across species, climate change and other stressors have caused reductions in the body size to which animals can grow, called asymptotic size, with consequences for demography. A

Performance Comparison of Three Data-Poor Methods With Various Types of Data on Assessing Southern Atlantic Albacore Fishery

Autor: Baochao Liao, Youwei Xu, Mingshuai Sun, Kui Zhang, Qun Liu

Publikováno v: Frontiers in Marine Science, Vol 9 (2022)

In the world, more than 80% of the fisheries by numbers and about half of the catches have not been formally analyzed and evaluated due to limited data. It has led to the fast growth of data-poor evaluation methods. There have been various studies ca

The conservation status and population decline of the African penguin deconstructed in space and time

Autor: Richard B. Sherley, Robert J. M. Crawford, Andrew D. deBlocq, Bruce M. Dyer, Deon Geldenhuys, Christina Hagen, Jessica Kemper, Azwianewi B. Makhado, Lorien Pichegru, Desmond Tom, Leshia Upfold, Johan Visagie, Lauren J. Waller, Henning Winker

Publikováno v: Ecology and Evolution, Vol 10, Iss 15, Pp 8506-8516 (2020)

Abstract Understanding changes in abundance is crucial for conservation, but population growth rates often vary over space and time. We use 40 years of count data (1979–2019) and Bayesian state‐space models to assess the African penguin Spheniscu

Assessing extinction risk, conservation reliance, and down-listing potential for two endangered Hawaiian waterbirds

Autor: Charles B. van Rees, Chris S. Elphick, J. Michael Reed

Publikováno v: Avian Conservation and Ecology, Vol 17, Iss 1, p 29 (2022)

Conservation reliant species complicate the idealized view of endangered species recovery by depending on perpetual management to maintain viable populations, making the goal of de-listing via threat removal potentially unattainable. The Hawaiian Sti

Estimating IUCN Red List population reduction: JARA—A decision‐support tool applied to pelagic sharks

Autor: Richard B. Sherley, Henning Winker, Cassandra L. Rigby, Peter M. Kyne, Riley Pollom, Nathan Pacoureau, Katelyn Herman, John K. Carlson, Jamie S. Yin, Holly K. Kindsvater, Nicholas K. Dulvy

Publikováno v: Conservation Letters, Vol 13, Iss 2, Pp n/a-n/a (2020)

Abstract The International Union for Conservation of Nature's (IUCN) Red List is the global standard for quantifying extinction risk but assessing population reduction (criterion A) of wide‐ranging, long‐lived marine taxa remains difficult and co
