概括

伦敦的西欧子数量在伦敦.

科学领域:

生态生态学生态生态学
保护生物学保护生物学
哺乳动物学哺乳动物学

背景情况:

在过去的50年里,西欧 (*Erinaceus europaeus*) 种群在英国和欧洲大幅减少.
曾经在伦敦皇家公园很常见,但现在只能在孤立的群体中发现,比如在摄政公园.

研究的目的:

从2014年到2023年,监测伦敦里根特公园的子数量和空间分布.
评估人口的生存能力,繁殖成功,生存率和死亡原因.
识别导致鱼数量减少的因素,并为保护战略提供信息.

主要方法:

每年两次使用火和热摄像头进行夜间调查 (春季和秋季).
捕捉刺,标记,检查,并释放.
对人口规模,空间分布,繁殖成功,生存率和死亡原因的分析.

主要成果:

摄政公园的刺种群在前六年平均为28只,从2020年大幅下降至2023年春季的最低6只.
捕食,主要是狐 (59%的死亡率),是导致死亡的首要原因,尤其是幼 (96%).
刺分布从广泛转移到集中在东北象限,与人口减少相吻合.

结论:

摄政公园的刺种群非常小,如果没有立即的保护干预,它们面临着高度的灭绝风险.
糟糕的繁殖成功,低的生存率和高的掠食水平威胁着这个孤立群体的长期生存能力.
迫切需要采取保护行动,以防止伦敦中部的灭绝.

Hedgehog Signaling Pathway

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.
