Testing the Optimal Foraging Theory in a Generalist Feeder: The Case of Reintroduced European Pond Turtles and Its Impact on Macroinvertebrates Communities

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
In this study we investigated the macroinvertebrate (MI) communities in two newly created, man‐made ponds concurrently with the diet of captive‐bred European pond turtles that were translocated there. We aimed at assessing whether turtles were operating as generalist feeders, and if successive reintroductions of turtles would affect the overall MI ...

Strategies, costs and counter‐strategies to sexual coercion

open access: yesBiological 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.

Age and growth of larval Pacific flagfin mojarra (Eucinostomus currani) in coastal Ecuador based on otolith analysis

open access: yesCiencias Marinas
The flagfin mojarra (Eucinostomus currani) is an important subsistence fishery resource in local Ecuadorian markets; however, very little is known about the early life history and reproductive biology of this species. In 2016 and 2017, E.

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

open access: yesFreshwater 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 ...

Demersal fish community on the inner shelf of Ubatuba, southeastern Brazil

open access: yesBrazilian Journal of Oceanography, 1998
Fluctuations in the distribution and abundance of demersal fishes collected by otter trawl on the continental shelf of Ubatuba were examined over a two-year sampling period, in an area up to 50 m depth. A total of 111 species were collected. Seasonal and

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

open access: yesLimnology 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)

open access: yesEcology 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)

open access: yesJournal 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.
