概括

鼻子和羽毛疾病病毒 (BFDV) 在澳大利亚危的红中被检测到,这是一个新的非psittacine宿主. 监测显示,野生猛禽的流行率为25%,其基因型与猎物物种相关.

科学领域:

鸟类病毒学鸟类病毒学
野生动物疾病生态学野生动物疾病生态学
保护生物学保护生物学

背景情况:

鼻子和羽毛疾病病毒 (BFDV) 是一种主要影响鸟的重要病原体.
最近的发现表明,BFDV正在扩大其宿主范围,包括非psittacine物种,包括掠食鸟.
红 (Erythrotriorchis radiatus),一个危的澳大利亚猛禽,以前没有对BFDV感染进行过调查.

研究的目的:

报告首次检测并确定澳大利亚危的红公种群中BFDV的流行率.
为了确定这种猛禽种群中传播的BFDV的潜在来源和基因型.
评估BFDV对红鱼健康的潜在影响,并为未来的保护策略提供信息.

主要方法:

对一只红鸟幼的尸检确定了最初的BFDV病例.
在澳大利亚北部对红进行了广泛的监测,以评估流行率.
基于PCR的方法用于BFDV检测,并对阳性样本进行基因定型.

主要成果:

在25% (7/28) 的采样红鱼中检测到BFDV,这标志着该物种首次报告.
检测到的BFDV基因型与在当地类猎物物种 (,,) 中发现的基因型一致.
观察到青少年红的流行率较高的趋势,尽管在统计学上并不显著.

结论:

BFDV是临灭绝的红的新发现病原体,对其保护有影响.
这种病毒很可能通过对受感染的鱼种类的掠食传播到红鱼身上.
进一步的研究至关重要,以了解BFDV对红鱼健康的影响,人口动态,并制定有效的管理计划.

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.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
