Allometric Scaling in Environmental DNA Concentration of Japanese Eel Anguilla japonica Confirmed Under Laboratory and Natural Conditions 日本鳗 (Anguilla japonica) 环境 DNA 浓度中的异速生长标度在实验室和自然条件下得到证实

open access: yesIntegrative Conservation, EarlyView.
We demonstrated that Anguilla japonica eDNA concentration was allometrically scaled with their body size in both the laboratory and riverine environments. Integrating body size allometry has the potential to improve population abundance estimates in the field, whereas further clarification is required for understanding eDNA production mechanisms ...

Novel Natural History Observations on the Reproductive Biology of King Cobra (Ophiophagus hannah) From Yunnan Province, China 云南省眼镜王蛇繁殖生物学的野外观察

open access: yesIntegrative Conservation, EarlyView.
Here we report three cases of nesting behavior in Yunnan Province, China. Our observations confirmed the presence of multi‐individual participation during the nest guarding, and this behavior was associated with an exceptionally high clutch size. ABSTRACT Although the King Cobra (Ophiophagus hannah) has received considerable conservation attention ...

IUCN Red List of Ecosystems

open access: yesS.A.P.I.EN.S, 2012
We begin by briefly examining the achievements of the IUCN Red List of Threatened Species, and offering it as the model and motivator for the creation of the IUCN Red List of Ecosystems (RLE). The history of the RLE concept within IUCN is briefly summarized, from the first attempt to formally establish an RLE in 1996 to the present.

Characterizing China's Illegal Trade in Avifauna on Social Media 中国社交媒体上非法鸟类贸易的特征分析

open access: yesIntegrative Conservation, EarlyView.
Worldwide, illegal wildlife trade is an increasing threat to species conservation. Here, we used the social media data to characterize China's illegal online trade in avifauna for conservation implications. Our results found that 178 avian species have been posted online for illegal trading. ABSTRACT The illegal wildlife trade poses a growing threat to

Comparing the IUCN’s EICAT and Red List to improve assessments of the impact of biological invasions

open access: yes, 2020
The IUCN recommends the use of two distinct schemes to assess the impacts of biological invasions on biodiversity at the species level. The IUCN Red List of Threatened Species (Red List) categorises native species based on their risk of extinction.
