The Motion Picture: Leveraging Movement to Enhance AI Object Detection in Ecology

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
As AI methods become increasingly popular to automatically analyse ecology data, we investigate using movement information as a means to improve traditional object detection approaches (which are limited to static image information only) on over 35,000 annotated images from 1480 terrestrial, marine and freshwater locations, the most extensive ...

Fish Diversity and Environmental Relationships in the Jinsha River During the Initial Phases of the 10‐Year Fishing Ban: A Metabarcoding Approach

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
Using eDNA metabarcoding, we identified 61 fish species in the Jinsha river during the early stage of the Yangtze river fishing ban. Fish diversity showed seasonal and regional variation, with Cypriniformes as the dominant group. Key environmental factors like temperature and dissolved oxygen were closely linked to diversity patterns.

An analysis of Nigerian freshwater fishes: those under threat and conservation options [PDF]

open access: yes, 2005
The study assessed qualitatively the threat status of all nigerian freshwater fishes using such criteria as rarity, size at maturity, mode of reproduction, human population density, habitat degradation, pollution and range of each species among others ...

Effects of different pond culture conditions on the growth performance, survival rate, and biochemical composition of Acanthopagrus schlegeli and Apostichopus japonicus

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 4, August 2025.
Abstract In the pond culture production process, culture patterns and conditions have important impacts on the feeding, growth, metabolism, behavior, physiology, biochemistry, and immune responses of aquatic animals. These interact with the ecological environment to jointly determine the production outcome of pond culture.

The Mitochondrial Genome of the Imperiled Goliath Grouper Epinephelus itajara: Selective Pressures in Protein Coding Genes, Secondary Structure of tRNA Genes, and Phylogenetic Placement

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
This study presents the complete mitochondrial genome of the critically endangered Goliath Grouper (Epinephelus itajara), totaling 16,561 bp and comprising 13 protein‐coding genes, 22 tRNAs, and two rRNAs. Genomic analysis revealed conserved gene order, A + T‐rich codon usage, and purifying selection across all protein‐coding genes, providing valuable ...

Genetic barcoding and preliminary phylogenetic analysis of Serranidae species from Maltese coastal waters, with a perspective on their Mediterranean phylogeography [PDF]

open access: yes, 2016
Ten species of the Serranidae Family sampled from the Mediterranean, including two non- native species, were identified using molecular genetic tools. Two mitochondrial genes, cytochrome c oxidase subunit I (COI) and Cytochrome b (Cyt b) genes were ...

Larval development of the Mexican Snook, Centropomus poeyi (Teleostei: Centropomidae)

open access: yesNeotropical Ichthyology, 2018
We document for the first time the early ontogeny of Centropomus poeyi based on captive raised material representing 0-19 days posthatch (dph). The achievement of early developmental landmarks (i.e., yolk-sac depletion, flexion, development of fins) and ...

Monthly eDNA Metabarcoding Data From the Coastal North Sea Area Align With Fish Species‐Specific Life Cycle Events

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
In this study, we investigated the temporal and spatial patterns of fish communities within the 12 nautical miles limit of the Belgian part of the North Sea (BPNS) using eDNA 12S metabarcoding. Our findings revealed that while there are no temporal changes at the community level, species‐specific eDNA signals align with the species known biology in the

Impoundment Effects on Water Quality as Reflected in Parasitism of Reservoir Basses [PDF]

open access: yes, 1971
Our aquatic environments are rapidly becoming useless as natural resources through pollution from various sources. It is therefore necessary for us to further understand the various means which relate to this process.
