Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Diversity of Waterbirds in the Sebuku Strait Kotabaru, South Kalimantan [PDF]

, 2015
This research is to determine the diversity of waterbirds in the Sebuku Strait (Pulau Laut Timur and Pulau Sebuku), Kotabaru, South Kalimantan. Communities of waterbirds identified in the mangrove forest (HM); rice paddies and ponds (Sw-Ta); wetlands and

A “demand and supply” approach to monitoring habitat and population changes of migratory birds

Frontiers in Ecology and the Environment, EarlyView.
Habitat loss and degradation threaten thousands of migratory bird species worldwide. Yet, because the distributions of migratory birds change throughout the year, quantifying the impacts of threats and identifying key sites for conservation attention have proved challenging.

Birds and Climate Change: Ecological Disruption in Motion [PDF]

, 2009
Analysis of four decades of Christmas Bird Count observations reveal that birds seen in North America during the first weeks of winter have moved dramatically northward -- toward colder latitudes -- over the past four decades.

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, EarlyView.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Extended Strahler Ordering to Distinguish Mapped River Channels From Overland Flow Pathways and Consistently Compare Digital Networks

River Research and Applications, EarlyView.
ABSTRACT Digital networks are virtual representations of freshwater systems that provide important inputs to, and mapping of, river classifications, simulation models, and quantitative data analyses for policy, planning, and management. Strahler order has often been used to characterize network configuration and as a proxy indicator of river channel ...

Shallow sub-lakes are essential for sustaining the successful wintering of waterbirds in Poyang Lake, China

Avian Research
For migratory waterbirds, the quality of wintering habitat is related to spring migration and successful breeding in the next year. The availability of food resources in the habitat is critical and varies within water levels.

Population trends, threats, and conservation recommendations for waterbirds in China

Avian Research, 2018
Background China is one of the countries with abundant waterbird diversity. Over the past decades, China’s waterbirds have suffered increasing threats from direct and indirect human activities.

Using time‐series remote sensing to identify and track individual bird nests at large scales

Remote Sensing in Ecology and Conservation, EarlyView.
Time‐series airborne imagery can potentially track individuals over time to collect information beyond one‐off counts. Using weekly UAS‐based imagery of wading bird colonies, we develop an automated approach to identifying nests. Our algorithmic approach detected 68–74% of known nests and exhibited similar performance to human review of imagery ...

Deteriorating habitat suitability and connectivity of waterbirds in the Bohai Sea Rim: Consequences of land use transformation

Global Ecology and Conservation
Wetlands in the Bohai Sea Rim play an indispensable role in maintaining the stability of waterbird populations on the East Asian-Australian flyway. However, motivated by economic development and urban expansion, coastal wetlands in this region have been ...
