Use of road infrastructure for movement by common terrestrial vertebrates 常见陆生脊椎动物移动过程中对道路基础设施的利用

open access: yesWildlife Letters, Volume 1, Issue 3, Page 97-106, September 2023., 2023
In this study, we aimed to determine whether common terrestrial vertebrates used drainage culverts to cross roads, relative to rates of surface crossings. We expected that culvert characteristics (e.g., length, height, width, and openness ratio) and/or environmental characteristics (e.g., vegetation density) would influence road crossing behavior.

Survey optimization for invasive Burmese pythons informed by camera traps 基于自动相机监测技术的入侵物种缅甸蟒的调查优化

open access: yesWildlife Letters, Volume 1, Issue 3, Page 143-148, September 2023., 2023
We evaluated the utility of camera traps to survey invasive Burmese pythons in the Florida Keys by deploying cameras pointed towards target areas of known radiotagged snakes under two trigger mechanisms—motion‐triggered or timelapse. We estimated detection probability and diel activity to optimize future surveys using timelapse camera traps and paired ...

A novel red‐edge spectral index for retrieving the leaf chlorophyll content

open access: yesMethods in Ecology and Evolution, Volume 13, Issue 12, Page 2771-2787, December 2022., 2022
Abstract The leaf chlorophyll content (Chlleaf) is a crucial vegetation parameter in carbon cycle modelling and agricultural monitoring at local, regional and global scales. The red‐edge spectral region is sensitive to variations in Chlleaf. An increasing number of sensors are capable of sampling red‐edge bands, providing opportunities to estimate ...

Functional diversity loss and change in nocturnal behavior of mammals under anthropogenic disturbance

open access: yesConservation Biology, Volume 36, Issue 3, June 2022., 2022
Abstract In the Anthropocene, understanding the impacts of anthropogenic influence on biodiversity and behavior of vulnerable wildlife communities is increasingly relevant to effective conservation. However, comparative studies aimed at disentangling the concurrent effect of different types of human disturbance on multifaceted biodiversity and on ...

A strategy for the next decade to address data deficiency in neglected biodiversity

open access: yesConservation Biology, Volume 35, Issue 2, Page 502-509, April 2021., 2021
Abstract Measuring progress toward international biodiversity targets requires robust information on the conservation status of species, which the International Union for Conservation of Nature (IUCN) Red List of Threatened Species provides. However, data and capacity are lacking for most hyperdiverse groups, such as invertebrates, plants, and fungi ...

Fauna and distribution of Testacea (Protozoa) from Arctic, Antarctic and Tibet [PDF]

open access: yes, 2010
野生动物多样性是生物多样性监测与保护管理评价的关键指标,因此对野生动物进行长期监测是中国森林生物多样性监测网络(CForBio)等大尺度生物多样性监测研究计划的一个重要组成部分.2011年以来,CForBio网络陆续在多个森林动态监测样地开展以红外相机来监测野生动物多样性.随着我国野生动物红外相机监测网络的初步形成,亟待建立和执行基于红外相机技术的统一监测规范.基于3年来在我国森林动态监测样地红外相机监测的进展情况,以及热带生态评价与监测网络针对陆生脊椎动物(兽类和鸟类)所提出的红外相机监测规范 ...
