Decision analysis rooted in Indigenous and Western scientific knowledge identifies cost‐effective strategies for managing hyperabundant deer to restore keystone places

open access: yesPeople and Nature, Volume 8, Issue 1, Page 4-20, January 2026.
Abstract The hyperabundance of herbivores—a result of altered human relationality with the land and the extirpation of predators—is leading to large‐scale degradation of keystone ecosystems across the globe. Designing and implementing socially acceptable and cost‐effective strategies that meaningfully reduce herbivore populations while allowing for the

Allozyme diversity in endemic flowering plant species of the Juan Fernandez Archipelago, Chile: ecological and historical factors with implications for conservation.

open access: yesAmerican-Eurasian journal of botany, 2001
The level and apportionment of allozyme diversity were determined for 29 endemic (and 1 native) species from the Juan Fernández Islands, Chile. Mean diversities at the species level (H(es) = 0.065) are low but comparable to those measured for other ...

Do Island Spiders Descend From Trees? – A Tale of Island Colonisation and Niche Expansion

open access: yesJournal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim Oceanic islands are known for being home to drastically different communities compared to the mainland, as their isolation and limited area significantly favour clades able to travel long distances over water. On spiders, this happens mainly, although not exclusively, through ballooning whose propensity is unevenly distributed across ...

Water availability and evolutionary similarity shape the global distribution of ferns with chlorophyllous spores

open access: yesEcography, Volume 2025, Issue 11, November 2025.
About 14% of all fern species have chlorophyllous spores, which lack dormancy, have thin walls, and have a shorter viability (only a few days in some species). These spores should have limited dispersal distances and be more susceptible to harsher climatic conditions, raising questions about the evolutionary and ecological significance of this trait ...

The far side of capitalism: Institutions and trade financing in Manila during the long eighteenth century

open access: yesThe Economic History Review, Volume 78, Issue 4, Page 1068-1087, November 2025.
Abstract Sustained long‐distance trade in the early modern era necessitated institutional mechanisms capable of solving three interrelated challenges: the need to mobilize an unprecedented volume of capital and to lock it in for long periods of time, ways of mitigating the principal–agent problem across continents, and methods to internalize and ...

Synthesizing Archetypes of Social‐Ecological Systems: Identifying Common Building Blocks

open access: yesEnvironmental Policy and Governance, Volume 35, Issue 5, Page 882-897, October 2025.
ABSTRACT A growing number of studies apply the social‐ecological systems (SES) framework with its standardized set of variables to examine place‐based environmental governance. Yet, due to the wide diversity of social‐ecological systems, a general theory about how variables interact—and systems can be governed—lacks empirical support. Despite many case
