Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

open access: yesArchaeology in Oceania, Volume 61, Issue 1, Page 177-198, April 2026.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.

Diversity of immunoglobulin light chain genes in non-teleost ray-finned fish uncovers IgL subdivision into five ancient isotypes [PDF]

open access: yes, 2018
The aim of this study was to fill important gaps in the evolutionary history of immunoglobulins by examining the structure and diversity of IgL genes in non-teleost ray-finned fish.

Unicorn leatherjacket filefish, Aluterus monoceros (Actinopterygii: Tetraodontiformes: Monacanthidae): first record off the Tunisian coast and confirmed occurrence in the Mediterranean Sea [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2011
Investigations conducted off the northern Tunisian coast (central Mediterranean) allowed the authors to collect a male of the unicorn leatherjacket filefish, Aluterus monoceros (L.).

Geographic Patterns of Intra‐ and Interspecific Diversity of Riverine Fish Species in the Italian Northern Apennines and Ligurian Alps

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We investigated the suitability of environmental DNA (eDNA) metabarcoding to identify inter‐ and intraspecific diversity patterns of riverine fish populations across the Adriatic and Ligurian drainage basins in Northern Italy. Our results revealed genetic as well as community differentiations, with the Adriatic side displaying higher taxon richness ...

SPECIATION IN NORTH AMERICAN BLACK BASSES, MICROPTERUS (ACTINOPTERYGII: CENTRARCHIDAE) [PDF]

open access: yesEvolution, 2003
The Pleistocene Epoch has been frequently cited as a period of intense speciation for a significant portion of temperate continental biotas. To critically assess the role of Pleistocene glaciations on the evolution of the freshwater fish clade Micropterus, we use a phylogenetic analysis of complete gene sequences from two mitochondrial genes ...

The lower actinopterygian fauna from the Lower Carboniferous Albert shale formation of New Brunswick, Canada – a review of previously described taxa and a description of a new genus and species [PDF]

open access: yes, 2017
The Lower Carboniferous Albert shale formation of New Brunswick, Canada, is well-known for the preservation of countless articulated lower actinopterygian palaeoniscoid fishes. This site is at the boundary between the Devonian and the Lower Carboniferous,

Recovering Historical eDNA From Museum‐Preserved Filter Feeders via Non‐Destructive Metabarcoding

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Recent technical advances have significantly enhanced the value of museum specimens for molecular research, with metagenomic and metabarcoding approaches expanding further the utility of museum collections. However, given the finite number of specimens, there is a critical need to move past destructive DNA extraction approaches and to explore ...

Growth, age and size of the Jurassic pachycormid Leedsichthys problematicus (Osteichthyes: Actinopterygii) [PDF]

open access: yes, 2013
The Jurassic pachycormid osteichthyan Leedsichthys problematicus is renowned for having been able to achieve prodigious size for a bony fish. Building on work of MARTILL (1986a), a thorough examination of all known material was conducted in order to ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Genetic Diversity Impacts Climate‐Induced Species Range Shifts

open access: yesEcology Letters, Volume 29, Issue 4, April 2026.
Genetic diversity may buffer species against climate‐driven range contractions and facilitate expansions, but its role at a global scale remains unclear. Using 4673 range shift estimates for 1888 species, we show that higher genetic diversity reduces trailing edge contractions under rapid warming and accelerates leading edge expansions under moderate ...
