Mapping the density of giant trees in the Amazon

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Networking strategies for coordinating interdependent policy issues: A motif approach

Policy Studies Journal, Volume 53, Issue 4, Page 925-943, November 2025.
Abstract Complex societal challenges, such as climate change and environmental degradation, are encumbered by numerous interdependences across different policy issues. Coordination of interdependent policy issues is thus critical. However, coordination challenges persist, partly because coordinating interdependent policy issues among actors often ...

Knowledge from non‐English‐language studies broadens contributions to conservation policy and helps to tackle bias in biodiversity data

Journal of Applied Ecology, Volume 62, Issue 9, Page 2148-2162, September 2025.
Collecting data from local sources markedly further strengthens global biodiversity databases by adding species not previously included in international datasets. Furthermore, the addition of these data helps to understand spatial and temporal biases that potentially influence abundance trends at both national and global levels.

Incorporating cyclone risk in the design of marine protected and conserved areas as an ecosystem‐based adaptation approach

Conservation Biology, Volume 39, Issue 4, August 2025.
Abstract Marine protected and conserved areas (MPCAs) are promoted as an ecosystem‐based adaptation (EbA) approach to increase community and ecosystem resilience to climate change. However, traditional approaches to MPCA design typically do not consider climate risk or habitat condition under a climate threat.

Do Formal Stance Strategies Reveal Disciplinary Variation in Professional Scientific Writing?

International Journal of Applied Linguistics, Volume 35, Issue 3, Page 1242-1261, August 2025.
ABSTRACT Stance in academic discourse has been extensively studied, with numerous investigations indicating that its expression varies across disciplines, depending on the authors’ intention to either enhance or diminish their voice or presence (e.g., It seems fairly certain vs. This is based on the belief that…).
