Evidence of Genetic Continuity in the Shortfin Mako Shark (Isurus oxyrinchus) Between the Eastern Atlantic and Mediterranean Sea

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Genomic analyses of shortfin mako sharks from the Eastern Atlantic and Mediterranean Sea reveal a single genetically mixed population, indicating high connectivity across basins. Demographic reconstruction suggests historical stability, though recent declines may be beyond the resolution of our markers. These results underscore the need for coordinated

First Record of a Presumed Risso's Dolphin Calf Associated With a Bottlenose Dolphin in the Mediterranean Sea

Ecology and Evolution, Volume 16, Issue 4, April 2026.
During a survey in June 2025, researchers recorded a presumed Risso's dolphin calf swimming in echelon position within a bottlenose dolphin group off the Catalan coast (north‐eastern Iberian Peninsula). Two possible interpretations are discussed: (1) it may represent the first hybrid calf reported in the Mediterranean, or (2) it may be the first ...

Moth Communities Are More Diverse in the Understory Than in the Canopy of a Tropical Lowland Rainforest in NW Ecuador

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We investigate the stratification of five clades of Lepidoptera: Erebidae‐Arctiinae, Geometridae, Hedylidae, Saturniidae, and Sphingidae in a tropical rain forest of the Chocó region in NW Ecuador. Average species richness was higher in the understory, median sample sizes were similar between strata and we found more species in regenerating forests ...

Evaluation of the Population Genetic Structure of Anadara tuberculosa (Mollusca, Bivalvia) in the Panamanian Pacific

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Our study analyzed the population genetics of Anadara tuberculosa (concha negra) in five Panamanian Pacific mangrove areas using the mitochondrial COI gene. We found high haplotypic diversity and low nucleotide diversity, a pattern that suggests a recent demographic expansion, which was supported by our neutrality tests and a star‐shaped haplotype ...

Tell Me How Much DNA You Have and I'll Tell You What Your Sex Is: Sex Determination by Flow Cytometry of Spiderlings of Allocosa marindia

Ecology and Evolution, Volume 16, Issue 4, April 2026.
The manuscript addresses the sex determination of spiderlings of the wolf spider Allocosa marindia using flow cytometry. Spiders are born with a defined sex, but it is not possible to determine their sex phenotypically until the adult or near‐adult stage. Sex identification at early stages of development is of great interest for studies in evolutionary
