Effects of live-bait shrimp trawling on seagrass beds and fish bycatch in Tampa Bay, Florida [PDF]

, 1999
The use of live shrimp for bait in recreational fishing has resulted in a controversial fishery for shrimp in Florida. In this fishery, night collections are conducted over seagrass beds with roller beam trawls to capture live shrimp, primarily ...

Strategies, costs and counter‐strategies to sexual coercion

Biological Reviews, Volume 100, Issue 4, Page 1557-1577, August 2025.
ABSTRACT Sexual conflict, the conflict between the evolutionary interests of females and males over mating, occasionally results in the evolution of traits favourable for one sex and adverse for the other. In this context, males can use sexual coercion to increase their mating success, at the expense of their female targets' mate choice.

Consumption to biomass (Q/B) ratio and estimates of Q/B-predictor parameters for Caribbean fishes [PDF]

, 2002
Estimates of the Q/B ratio and parameters of equations to 'predict' Q/B values for 116 fish stocks in the Gulf of Salamanca, Colombia are presented. A compilation of these estimates available for Caribbean Sea fishes (264 stocks) is also provided for ...

Length–Dry Mass Relationships of Aquatic Insects: Geographic and Taxonomic Variation in a Digital Database

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Aquatic insects are an abundant, yet declining, taxonomically heterogeneous group with special importance in both aquatic and terrestrial ecosystems. Accurate estimations of insect biomass during their aquatic life stages are essential to advance our fundamental knowledge about insects, their roles in ecosystems, and their vulnerability to ...

Spatiotemporal assessment of benthic macroinvertebrate communities in the Bermejo River Basin in the Ecuadorian Amazonia

Limnology and Oceanography Letters, Volume 10, Issue 3, Page 371-380, June 2025.
Abstract The Cofán communities rely on the Cofán Bermejo Ecological Reserve for their survival and cultural practices. Due to the rugged and inaccessible topography of the reserve in the Northern Ecuadorian Amazon region, limited biomonitoring and ecological characterization studies of the ecosystem health have been conducted.

Why the Long “Horns”? Fine‐Scale Morphology Suggests Tactile Demands Contributed to the Exaggeration of Male Longhorned Beetle Antennae (Coleoptera: Cerambycidae)

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Exceptionally elongated antennae are common in male longhorned beetles (Coleoptera: Cerambycidae), but their function and evolution are poorly understood. Through scanning electron microscopy and antennal morphometrics of multiple Anoplistes species (Cerambycidae), our study revealed that elongate antennae are more likely adaptive for close‐range ...

Embryonic Development of Appasus japonicus Vuillefroy, With Special Reference to Mouthparts Formation (Insecta: Heteroptera, Belostomatidae)

Journal of Morphology, Volume 286, Issue 5, May 2025.
In this study, we provide a detailed description of the embryonic development of Appasus japonicus, focusing on the formation of its specialized mouthparts. We identify homologies between the maxillary plate and maxillary palp and most parts of the stylet‐like mandibles and maxillae are housed within the labial palp.

Structural and Numerical Chromosome Diversification in Marine Perciformes (Priacanthidae and Gerreidae)

CYTOLOGIA, 2006
The Perciformes are characterized by a remarkable chromosomal homogeneity, with a small percentage of its representatives bearing diploid numbers higher or lower than their putative basal number (2n=48). Due to the wide diversity of this group, several families from this order lack cytogenetic reports, such as Gerreidae and Priacanthidae.

Assessing Fish Community Structure and Diversity Across Environmental Gradients in a Tropical Bay

Marine Ecology, Volume 46, Issue 2, March 2025.
ABSTRACT Understanding the relationship between species distribution and the environment across spatial gradients is crucial for biodiversity evaluation. We surveyed fish populations in a tropical bay, covering a spatial gradient from the outer zone with favorable marine conditions to the inner zone affected by human activities.
