The oxygen uptake capacity of freshwater fish evolves to favour hypoxia tolerance in lentic species but locomotion capacity in lotic species

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Oxygen supply capacity (α) is a physiological trait hypothesized to shape the metabolic niche and biogeography of aquatic breathers, yet how natural selection targets α remains unclear.

Elevated nitrogen deposition protects an invasive plant from herbivory through altering leaf volatile‐mediated tritrophic interactions

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Atmospheric nitrogen deposition disrupts plant–herbivore interactions, but its impact on leaf volatile organic compounds (VOCs)‐mediated multi‐trophic herbivore resistance remains unclear within the context of plant invasion. In this study, we initially investigated the

Plant invasion in mountain ecosystems reduces soil micro‐food web complexity at higher elevations

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Anthropogenic activities have accelerated plant invasions in mountain ecosystems, impacting the structure and functions of native plant communities. Changes in above‐ground vegetation can drive shifts in below‐ground biota, yet the effects of plant invasions on soil ...

Herbivory enhances cadmium foraging in the invasive hyperaccumulating plant Phytolacca americana

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Biological invasions and heavy metal pollution are two pervasive environmental challenges threatening global ecosystems. While the elemental defence hypothesis posits that certain plants accumulate heavy metals to deter herbivores, it remains unclear whether invasive ...

Saline versus alkaline stresses in paddy soils drive divergent microbial nutrient limitations despite shared carbon constraints

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil salinization and alkalization often suppress microbial functional activity, triggering negative feedback loops in microbial metabolism, degrading nutrients and agricultural productivity.

Sixteen Years Later: Revisiting Cultural Complexes and the Roots of Archetypal Thematic Analysis (ATA)1

open access: yesJournal of Analytical Psychology, EarlyView.
Abstract Written as a letter to my 28‐year‐old self, this paper explores the development of my engagement with cultural complexes. On August 18, 2009, I finished a chapter applying cultural complexes to a history of China, complete with elaborate charts that seemed to confirm a process by which cultural complexes are formed, and how China’s then recent

Emerging applications of large language models in ecology and conservation science

open access: yesConservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Twelve principles for successful governance of community‐based coastal marine restoration

open access: yesConservation Biology, EarlyView.
Abstract Global agreements, such as the Global Biodiversity Framework, call for urgent, large‐scale action to halt biodiversity loss through a whole‐of‐society approach. Community‐based restoration can play a crucial role in achieving this goal, yet there remains limited understanding of what makes these projects effective and sustainable.
