Identifying personality traits and behavioural syndromes in a threatened freshwater fish (Nannoperca vittata) through comparative analysis with a model species (Poecilia reticulata): Implications for conservation

open access: yesEcology of Freshwater Fish, Volume 34, Issue 1, January 2025.
Abstract Animal personalities are differences in behaviour among individuals of the same species that are consistent over time and contexts. The integration of animal personality into conservation actions is hampered by limited understanding of personality traits in non‐model organisms.

Assessing the net effect of anthropogenic disturbance on aquatic communities in wetlands: community structure relative to distance from canals [PDF]

open access: yes, 2006
Anthropogenic alterations of natural hydrology are common in wetlands and often increase water permanence, converting ephemeral habitats into permanent ones.

Evaluation of Chlorpyriphos as an Organophosphate Pesticide on Hematology, Blood Biochemistry, Antioxidant Capacity, Oxidative Stress, and Histopathological Changes in Juvenile Silver Barb (Barbonymus gonionotus)

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
The freshwater fish population in Bangladesh is adversely affected by the use of pesticides in agriculture. Furthermore, pesticide consumption is increasing daily due to the introduction of high‐yielding crop varieties. This study aimed to examine the impact of the organophosphate pesticide chlorpyriphos on various pathological alterations and acute ...

Checklist of the Freshwater Fishes of Argentina (CLOFFAR) [PDF]

open access: yes, 2015
The purpose of this paper is to present an updated list of freshwater fishes found in Argentina based on the available literature. Since the last list was published in 2003, most systematical and distributional changes were presented on www.pecescriollos.

Interactions Between Non‐Native Western Mosquitofish and Native Bluegill Sunfish: Mesocosm Experiments

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
Native Bluegill Sunfish had important competitive impacts on invasive Western Mosquitofish and also had intraguild predation effects that prevented successful recruitment of Western Mosquitofish. In contrast, Bluegill Sunfish were affected by intraspecific effects more than by interspecific effects from Western Mosquitofish.

Accelerating imaging research at large‐scale scientific facilities through scientific computing

open access: yesJournal of Synchrotron Radiation, Volume 31, Issue 5, Page 1317-1326, September 2024.
Scientific computing augmentation paving the way for the advent of next‐generation synchrotron imaging research is discussed.To date, computed tomography experiments, carried‐out at synchrotron radiation facilities worldwide, pose a tremendous challenge in terms of the breadth and complexity of the experimental datasets produced. Furthermore, near real‐

Fish assemblages found in tidal-creek and seagrass habitats in the Suwannee River estuary [PDF]

open access: yes, 2006
Fish assemblages were investigated in tidal-creek and seagrass habitats in the Suwannee River estuary, Florida. A total of 91,571 fish representing 43 families were collected in monthly seine samples from January 1997 to December 1999.

Evolutionary diversity and turn-over of sex determination in teleost fishes. [PDF]

open access: yes, 2009

Electrophoretic Demonstration of the Hybrid Origin of the Gynogenetic Teleost Poecilia formosa

open access: yesThe American Naturalist, 1968
Electrophoretic serum protein analysis reveals that the gynogenetic species Poecilia formosa possesses two albumin bands that are identical with those of laboratory-produced hybrids of its two sympatric species, P. latipinna and P. mexicana. The presumed parental species possess single albumins that are different in electrophoretic mobility.
