The Evolution of Male Weapons Is Associated with the Type of Breeding Site in a Clade of Neotropical Frogs

open access: yesIntegrative Zoology, EarlyView.
Male weaponry evolution is often linked to male–male competition, but its relationship with breeding site type remains unclear. Using Leptodactylinae frogs, we found a macroevolutionary correlation between breeding site type and weapon evolution. Also, gains and losses of weapons occurred more frequently in exposed‐breeding sites, an unexpected finding.

Norwegian Blues? Rethinking the Idea of Middle Powers in an Era of Fuzzy Bifurcation

open access: yesGlobal Policy, EarlyView.
ABSTRACT Unsuccessful efforts to update the middle power concept for the contemporary international system have prompted calls for the concept to be “historicized”—to be retired from common use and treated as a purely historical term. The problem with this proposal is that “middle power” has become increasingly popular in the 2020s in analysis ...

The Mobility Politics of Hong Kong's High‐Speed Rail

open access: yesAsia Pacific Viewpoint, EarlyView.
ABSTRACT Human geography scholarship has revealed how powerful and marginalised actors alike may use (im)mobility to exert authority, and it has recognised the ability of infrastructure to either consolidate or undermine state power. This paper uses new evidence to demonstrate how Hong Kong's express rail link (XRL) to Mainland China was implicated in ...

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Long‐Term Changes in Dominant Fisheries Species and Their Relationship With Surface Oceanic Conditions in the Waters Around the Korean Peninsula From 1980 to 2019

open access: yesFisheries Oceanography, Volume 35, Issue 2, Page 267-284, March 2026.
ABSTRACT The waters surrounding Korea are an economically–ecologically important region due to their high fishery productivity and role as seasonal migratory routes for the spawning and growth of commercially valuable species. We evaluated temporal changes in dominant fisheries species in encompassing large marine ecosystem (LME) areas 47, 48, and 50 ...
