Asymmetric species turnover underpins the latitudinal diversity gradient in the Western Ghats biodiversity hotspot of India

open access: yesEcography, EarlyView.
Latitudinal diversity gradients (LDGs), namely an increase in species richness from higher to lower latitudes, are one of ecology's best documented patterns, yet how the fundamental components of compositional mismatches (i.e. species gains and losses along a gradient) explain these patterns remains poorly understood.

Rising, falling, stalling: complex biodiversity trajectories in English rivers

open access: yesEcography, EarlyView.
Freshwater ecosystems face intense anthropogenic pressures. Yet in parts of Europe, including the UK, studies have documented widespread increases in macroinvertebrate diversity following investments to improve water quality. More recent analyses, however, suggest that these gains have slowed, plateaued, or even reversed. Despite increasing recognition

Thermal niche breadth shapes regional elevational range sizes of tropical‐like mountain stream insects: evidence for Janzen's tropical mountain passes hypothesis

open access: yesEcography, EarlyView.
The core of Janzen's tropical mountain passes hypothesis is that relatively stable annual temperature variation limits species' thermal tolerances breadth, which, in combination with steep elevational temperature gradients, constrains the elevational distributions of these species. In addition to thermal niche breadth, elevational ranges were shaped by

Modeling climate adaptive habitat connectivity for conservation planning in Colombia

open access: yesEcography, EarlyView.
To remain effective under global change, conservation decisions must anticipate shifting climates, species responses to climate change and the dispersal pathways needed to track suitable climate. Yet most assessments of ecological connectivity do not consider how the landscape will change, or, if they do, they only consider a single future time point ...

Nested Carbon Governance in Southeast Asia: Towards Just Nature‐Based Solutions?

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Nature‐based solutions (NbS) have gained prominence as an integrated approach to addressing climate change and biodiversity loss while supporting sustainable development. Yet, their implementation across Southeast Asia remains fragmented and often contested.

Environmental Statecraft, Fragmented Authoritarianism, and Technocratic Governance: The Structure and Agency of China's Local Environmental Politics

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Local environmental politics in China is often said to be dominated by state‐controlled modes of multi‐level governance. However, top‐down governance is embedded within and transformed by local politics, adding complexity to governance practices and environmental outcomes.

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...
