压力对灰小鼠狐猴生存的影响

高水平的皮质醇和降低的生存率似乎具有关联。还发现，非常好的身体状况与每半年的生存增加有关，但在生殖季节却没有。寄生虫的变化不能预测生存。

这项研究表明，长期增加的糖皮质激素水平可能与存活率负相关。这些结果强调了考虑可能影响糖皮质激素水平的环境压力，从而影响生存。

Population decline is often hard to measure, and this study demonstrates how an individual health indicator, such as long-term stress levels, may provide an alternate and easier method for detecting issues at a population level, thereby predicting wild populations’ responses to environmental challenges.

狂热的捕蝇器

还发现，非洲春季移民的开始，越过撒哈拉沙漠的时机在晚期和早期弹簧之间保持一致。但是，繁殖地点的到来取决于每年中途停留点的春季物候。

This study progresses our understanding of how a species biological rhythms and their external environmental stimuli interact. This enables us to greater understand how climate change may impact on migratory animals.

A Citizen Science Approach to Investigating Road-kill Hotspots

Heiglet al。使用公民科学方法研究了三级道路上道路杀死的爬行动物和两栖动物的空间模式。开放访问遥感数据是通过使用公民科学应用程序获得的。

The authors monitored the reptile and amphibian road-kills along 97.5km of tertiary roads, stretching across interurban, municipal and agricultural roads as well as cycling paths. The data was collected in eastern Austria across two seasons.

72 reptile and 180 amphibian road-kills comprising eight species were recorded, mainly along agricultural roads. It was found that the highest concentrations of road-kills were located next to vineyards, suburban areas and arable land. Green toads, common toads and grass snakes were the most often found road-killed species.

发现在研究超过400公里的道路的情况下，专业研究人员的监视比监视公民科学方法更具成本效益。该信息可以帮助旨在减少道路杀伤和其他研究人员的当局以具有成本效益的方式实施对道路杀死热点的大规模监控。

哪些青蛙将在变化的热带森林中统治

Mareike Hirschfeld and Mark-Oliver Rödel investigated which traits make a species more tolerant to disturbances, thereby enabling their success and survival in altered tropical forests as well as pristine ones.

Through analyzing published data in 243 frog species, they identified which traits enabled these amphibians to cope most effectively to modifications of their natural environment.

那些最适合自然栖息地的人是：间接发展的物种具有广泛的海拔分布和范围较大的物种，这些物种与溪流和居住的叶子无关。

这项研究有助于通过确定可能在这些新环境中持续存在的特征来预测变化的热带森林中未来的青蛙群落。这些在青蛙中发现的特征也与在灭绝风险低的物种中发现的特征有关。

小龙虾破坏了猎物

The researchers found that increasing crayfish density decreased vegetation and animal prey density whilst also increasing the rate of growth of individual crayfish.

When the vegetation was replaced with an increased amount of artificial vegetation, the crayfish growth rate decreased and the survival of animal prey increased.

The experiments determine that the aquatic vegetation strengthens the bottom-up control of crayfish, but this effect is relaxed when the density of crayfish is increased.

这项研究有助于生态系统的恢复知识，因为耐受耐受销毁的淹没植物可能有助于重建其他水生植物，因此在小尺度上的无脊椎动物种群。
