Near-term ecological forecasting for dynamic aeroconservation of migratory birds. [PDF]

open access: yesConserv Biol, 2021
Abstract Near‐term ecological forecasting has the potential to mitigate negative impacts of human modifications on wildlife by directing efficient action through relevant and timely predictions. We used the U.S. avian migration system to highlight ecological forecasting applications for aeroconservation.

Connectivity between countries established by landbirds and raptors migrating along the African-Eurasian flyway. [PDF]

open access: yesConserv Biol, 2023
Abstract The conservation of long‐distance migratory birds requires coordination between the multiple countries connected by the movements of these species. The recent expansion of tracking studies is shedding new light on these movements, but much of this information is fragmented and inaccessible to conservation practitioners and policy makers.

On the normative roles of biodiversity and naturalness in conservation. [PDF]

open access: yesConserv Biol
Abstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States. [PDF]

open access: yesConserv Biol
Abstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

畲族迁徙“外因说”质疑 [PDF]

open access: closed, 1999
文章针对目前学术界所主张的畲族迁徒原因“外因说”提出质疑,指出历史上畲族不断迁徙的原因是极其复杂的,若将畲族迁徙的主要动力归结为外因,则很难对畲族为何形成特殊的移动规律、移动方向以及为何在明清封建压迫更加强化之时反而转向定居等问题作出圆满的解释。文章还指出 ...

Predictions of southern migration timing in coastal sharks under future ocean warming. [PDF]

open access: yesConserv Biol
Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

An emerging coastal wetland management dilemma between mangrove expansion and shorebird conservation. [PDF]

open access: yesConserv Biol, 2022
Abstract Coastal wetlands around the world have been degraded by human activities. Global declines in the extent of important coastal wetlands, including mangroves, salt marshes, and tidal flats, necessitate mitigation and restoration efforts. However, some well‐meaning management actions, particularly mangrove afforestation, can inadvertently cause ...
