Wild Cicer species exhibit superior leaf photosynthetic phosphorus‐ and water‐use efficiencies compared with cultivated chickpea under low‐phosphorus conditions

open access: yesNew Phytologist, Volume 247, Issue 1, Page 144-159, July 2025.
Summary Domesticated chickpea cultivars exhibit limited genetic diversity. This study evaluated the effects of chickpea domestication on phosphorus (P)‐use efficiency (PUE) under low‐P conditions, using a diverse Cicer collection, including wild species. Two wild Cicer species – 54 C. reticulatum accessions and 15 C. echinospermum accessions, and seven

Forest citizens and people‐centered conservation in the Brazilian Amazon

open access: yesConservation Biology, Volume 39, Issue 3, June 2025.
Abstract Demands for territorial recognition are foundational to the claiming of rights by forest‐proximate people who attempt to conserve their forests. The rights of these often‐marginalized populations have been largely overlooked by conservationists, yet they are central to achieving people‐centered conservation. We further developed the concept of

基于多源异构时空数据融合的交通流量预测模型

open access: yes大数据, 2023
交通流量预测问题具有多源异构性,未来时刻的流量不仅与之前时刻的流量相关,同时也受城市区域间关系、天气情况、兴趣点(point of interest,POI)等异构时空数据的影响。针对此问题,提出一种基于多源异构时空数据融合的交通流量预测模型MHF-STNet。首先使用聚类方法获得城市区域不同的流量模式,并使用拼接、权重相加、注意力机制等多种方式融合交通流量、城市区域间的位置关系、天气、POI、工作日、假期多个模态的时空数据,使用深度学习方法对异构数据统一建模,预测未来时刻的交通流量。在北京出租车 ...

Interdependencies between Indigenous peoples, local communities, and freshwater systems in a changing Amazon

open access: yesConservation Biology, Volume 39, Issue 3, June 2025.
Abstract Globally, Indigenous peoples and local communities (IPs and LCs) are fighting for the recognition of their knowledge and decision‐making authority in freshwater conservation. In the Amazon, decision‐making around freshwater management and conservation has often overlooked Indigenous and local knowledge (ILK) and the connections between ...
