SPECIATION IN THE FISHES OF THE GENUS MENIDIA [PDF]

Evolution, 1948
The genus Menidia, which includes the commoni silversides of the Atlantic and Gulf coasts of the United States, presents several aspects of interest for an evolutionary study. Members of this genus have repeatedly entered fresh water from the sea:-two full species, MU. audens and M.

Sex Ratio Selection and the Evolution of Environmental Sex Determination in Laboratory Populations of Menidia menidia [PDF]

Evolution, 1992
What happens when a population with environmental sex determination (ESD) experiences a change to an extreme environment that causes a highly unbalanced sex ratio? Theory predicts that frequency-dependent selection would increase the proportion of the minority sex and decrease the level of ESD in subsequent generations.

Adaptation to warm environments with a fast pace of life in a marine predatory snail

Ecological Monographs, Volume 96, Issue 2, May 2026.
Abstract Understanding how latitudinal temperature variation shapes local adaptation of life‐history strategies is crucial for predicting future responses to warming. Contrasting predictive frameworks explain how growth and other life‐history traits may respond to differing selective pressures across latitude. However, these frameworks have rarely been

COMPARATIVE GEOGRAPHIC VARIATION IN MENIDIA [PDF]

Evolution, 1974
Increasing evidence indicates an important influence of the physical environment on allozyme variation (Johnson et al., 1969; Koehn, 1969; Johnson, 1971; Koehn and Mitton, 1972; Kojima et al., 1972; Merritt, 1972; Koehn et al., 1973). One possible test of the importance of the external environment is a comparison of patterns of geographic variation in ...

Artificial oyster reefs can facilitate the recovery of lost ecosystem function in fragmented seagrass habitat

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Seagrasses suffer population decline when environmental stress exceeds physiological tolerance. In such instances, seagrass restoration can be successful if stressors are alleviated; however, many stressors cannot be addressed at a local scale. As such, seagrass restoration efforts often fail. In this study, we tested whether artificial oyster

Using deep learning to assess the toxicological effects of sublethal exposure of a novel green pesticide in a stored‐product beetle

Pest Management Science, Volume 82, Issue 5, Page 4319-4331, May 2026.
This study employs an AI‐driven multidisciplinary approach to increase our understanding of the toxicological effects of sublethal concentrations of carlina oxide on Prostephanus truncatus. Sublethal exposure to the carlina oxide induced changes in motor patterns and thigmotaxis, highlighting its potential role in integrated pest management strategies.

eDNA Metabarcoding Analysis of Bony Fish Identification in Coastal Water of Gulf of Maine Using Nested Polymerase Chain Reaction of 12S rRNA Universal Primers

Environmental DNA
Ecosystems in coastal waters of Gulf of Maine (GOM) are undergoing environmental challenges in response to climate change and anthropogenic stressors. eDNA metabarcoding, a powerful tool for assessing the fish community structure, was used to identify ...

The Abrupt and Persistent Decline in Recruitment Success in Northeast Arctic Cod: A Review of Probable Causes

Fish and Fisheries, Volume 27, Issue 3, Page 643-659, May 2026.
ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...
