Spatial Complexity and Rare‐Taxon Turnover Structures Benthic Coral Reef eDNA Communities
Molecular Ecology, Volume 35, Issue 14, July 2026.ABSTRACT Environmental DNA (eDNA) metabarcoding has transformed spatial biodiversity assessments, although its capacity to distinguish persistent from dynamic elements of ecological communities through time remains largely unknown. We asked to what degree eDNA signals on coral reefs are temporally consistent representations of community composition or ...

Target Detection Is Enhanced by Polarization Vision in a Fiddler Crab [PDF]
Current Biology, 2015 We are constantly surprised by the ability of relatively simple animals to perform precise visually guided movements within complex visual scenes, often using eyes with limited resolution. Exceptional examples include the capture of airborne prey by dragonflies, the learning flights of bees and wasps, and the tracking of conspecifics by crabs on ...

Ecology and Evolution, Volume 16, Issue 6, June 2026.Does dispersal differ between the sexes? Our findings underscore the power of genomic markers to study sex‐biased dispersal, elucidate sex determination systems, and facilitate sex assignment, with important implications for species conservation and management. ABSTRACT Does dispersal differ between the sexes?

Fiddler crabs from highly disturbed beaches are more sensitive to human presence [PDF]
Anais da Academia Brasileira de CiênciasThe presence of humans frequently modifies the behavior of animals, particularly their foraging patterns, compromising energetic demands. The fiddler crab Leptuca leptodactyla inhabits mangroves with high degrees of anthropogenic influence.

Flood facilitates cross‐ecosystem trophic subsidies to marine animals
Limnology and Oceanography, Volume 71, Issue 6, June 2026.Abstract Trophic subsidies are resources that cross ecosystem boundaries, influencing the structure and function of recipient food webs. Widespread regulation of rivers for human consumptive use has profoundly altered natural flow regimes, decoupling donor‐recipient dynamics between freshwater and marine ecosystems. We explored trophic subsidies to the

Evaluating the potential impact of bird predation on the SW Atlantic fiddler crab Leptuca uruguayensis [PDF]
, 2019 The southernmost permanent population of the fiddler crab Leptuca uruguayensis occurs along the Samborombón Bay (36°22′S, 56°45′W, Argentina), an important feeding site for many bird species, including ruddy turnstones (Arenaria interpres), whimbrels ...
