Microhabitat selectivity shapes the seascapeecology of a carnivorous macroalgae-associatedtropical fish

open access: yes, 2018
Habitat quantity and quality can be key drivers for the distribution and abundance of animals in heterogeneous landscapes. Macroalgal meadows are often a prominent component of tropical marine ecosystems, yet we have little understanding of how dynamic ...

A trophic model of the coastal fisheries ecosystem off the west coast of Sabah and Sarawak, Malaysia [PDF]

open access: yes
A mass-balance steady-state trophic model of the coastal fisheries ecosystem off the West Coasts of Sabah and Sarawak, Malaysia (10 - 60 m depth) was constructed using the Ecopath software. The ecosystem models were partitioned into 29 ecological/trophic

Metal accumulation in fish from different zones of a large, shallow freshwater lake

open access: yes, 2012
Metal (Cd, Pb, Cr, Ni, Mn, Cu, and Zn) concentrations in different fish species sampled from two distinct (phytoplankton- and macrophyte-dominated) lake zones of a large, shallow freshwater lake, Taihu Lake, were investigated.

The spread of non‐native species

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Benthic Microalgae Respond More Strongly to Warming and Salinity Than Zooplankton

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
The effects of multiple simultaneous stressors on different trophic levels are poorly known. Warming changed the composition of both benthic diatom and zooplankton communities, but the interaction of warming and decreasing salinity affected only benthic diatoms. ABSTRACT The effects of elevated temperature are pronounced in high latitudes where warming

Bird Diversity and Habitat Associations in the Tara Gedam Monastery Church Forest: A Seasonally Informed Study in Northwestern Ethiopia

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
This study explores how habitat structure and seasonal variation shape bird diversity in the Tara Gedam Monastery church forest of Ethiopia. Across wet and dry seasons, 94 species were recorded, with abundance higher in the wet season but diversity remaining stable, underscoring the forest's role as a perennial refuge.
