People and Nature, Volume 5, Issue 6, Page 2158-2177, December 2023., 2023 Abstract Global change is increasing the frequency and severity of human‐wildlife interactions by pushing people and wildlife into increasingly resource‐limited shared spaces. To understand the dynamics of human‐wildlife interactions and what may constitute human‐wildlife coexistence in the Anthropocene, there is a critical need to explore the spatial,

Journal of Ecology, Volume 111, Issue 12, Page 2733-2749, December 2023., 2023 Our results indicate that defoliation and fertilisation, two common grassland perturbations, have contrasting impacts on root traits of grassland plant species, with direct and indirect short‐term consequences for a wide range of soil abiotic and biotic properties that underpin ecosystem functioning.

Evaluating the potential of biodiversity offsets to achieve net gain
Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract Evaluating the outcomes and tracking the trajectory of biodiversity offsets is essential to demonstrating their effectiveness as a mechanism to conciliate development and conservation. We reviewed the literature to determine the principles that should underpin biodiversity offset planning and the criteria for offset evaluation at the project ...

Mycorrhiza‐induced alterations in the spatial structure of stands in a subtropical forest
Functional Ecology, Volume 40, Issue 3, Page 668-678, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Spatial aggregation patterns represent snapshots of ecological processes that occurred over an extensive period. Such processes can shape both the conspecific and the heterospecific spatial structure of plants across woody habitats.

, 1979 星系螺旋结构的密度波理论受到人们广泛的重视。考虑到波的有限群速度,以及星系激波的耗散,需要解决密度波的长期维持。不少工作采用线性密度波的不稳定模式来补偿波能的耗散,线性波还存在共转奇异性,有必要分析密度波的非线性增长。另一方面,数值试验都发现,在适当物理条件下的螺旋密度波是不稳定的 ...
