Hobbyist preferences for pet freshwater turtles
Conservation Biology, EarlyView.Abstract The burgeoning pet trade is a primary threat to wild freshwater turtles worldwide. Although the risks from commercial exploitation of turtles have been discussed widely, there is little empirical research on preferences for pet turtles from a hobbyists’ perspective.

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Study On Structure Mechanics Analysis Of High - rise Isolated Buildings In Moderate Earthquake Intensity And High Wind Pressure Area [PDF]
, 2017 隔震建筑经历了实际地震的考验，表现出了优良的减震性能；目前，人们对于高层隔震建筑的减震原理并未清晰，高层隔震建筑也存在结构倾覆稳定的问题，隔震技术并未广泛的应用于高层建筑中。高层隔震建筑在减震与抗风方面对隔震层刚度的要求存在矛盾之处，结构减震效应与风控的均衡，尤其是中烈度高风压地区，是个很有研究价值的课题。 本文对高层隔震建筑隔震层的设计展开了详细的介绍，输入三维地震波，验算了本文研究案例隔震层设计的可行性。从模态分析与反应谱分析的角度，研究了高层隔震建筑的减震原理；分析了高层隔震建筑在设防烈度为7度 ...

Informing spatial conservation prioritization with species’ traits
Conservation Biology, EarlyView.Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

Conservation Biology, EarlyView.Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Conservation Biology, EarlyView.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.
