The diel niche of brown bears: constraints on adaptive capacity in human‐modified landscapes

Ecography, Volume 2025, Issue 10, October 2025.
Diel activity rhythms, representing the behavioral pattern of the sleep–wake cycle, may be adjusted by wildlife in response to changes in environmental conditions. An increase in nocturnality is typically recognized as an adaptive strategy to segregate from humans and mitigate heat stress. Numerous studies have investigated spatial patterns and habitat

Recent and Rapid Assembly of an Island Species–Area Relationship Threatened by Human Disturbance

Ecology Letters, Volume 28, Issue 10, October 2025.
The island species–area relationship (ISAR), traditionally studied in millions of years old oceanic archipelagos, remains poorly understood in much younger insular systems. Using fish communities from 79 postglacial peri‐Alpine lakes, we show that classical ISAR patterns can emerge rapidly, contrary to expectations given their young age (< 15,000 years)

Identity and Distribution of Triglops metopias (Teleostei, Cottidae) in the Northwestern Pacific

Journal of Marine Science and Engineering
The Alaskan (highbrow) sculpin, Triglops metopias, is a rare and poorly known species with a restricted distribution in the North Pacific. This species has been previously recorded only from off the Aleutian Islands and the Gulf of Alaska, while previous

Resurveyed Island Vegetation Reveals That Species Colonisation and Extinction Probabilities Are Linked to Traits

Ecology Letters, Volume 28, Issue 10, October 2025.
We show that species richness and community trait composition on 132 Australian islands remained stable over six decades, despite high species turnover. Colonisation and extinction probabilities were linked to functional traits, challenging the neutrality assumption of classic island biogeography theory.

Global Coastal Biogeographic Boundaries: Unveiling the Nature of Processes Shaping the Distribution of Marine Biodiversity

Diversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Identify biogeographic boundaries that delineate the distribution of species assemblages along global non‐insular coastlines, characterise the potential barriers responsible for biogeographic boundaries and realign coastal biogeographic provinces. Location Global. Time Period Not applied. Major Taxa Studied Animalia.

Inventory of color polymorphism in populations of Dendrobates galactonotus (Anura: Dendrobatidae), a poison frog endemic to Brazil [PDF]

Phyllomedusa: Journal of Herpetology, 2012
We studied the various color morphs of Dendrobates galactonotus that occur in its range between the Amazon and Tapajós rivers, in the Brazilian states of Pará, Maranhão, northern Mato Grosso, and northern Tocantins. Dorsal coloration ranges from black to
