Neoichnology and sediment distribution in tidal flats of the mud‐dominated mesotidal Mira River estuary (Portugal)

Sedimentology, EarlyView.
ABSTRACT Invertebrate burrow morphologies and distributions are presented for the tidal flats of the middle and lower reaches of the tide‐influenced (mesotidal), mud‐dominated Mira River estuary (SW Portugal) as an analogue for interpreting the ichnology of palaeoestuarine successions.

Population structure and reproductive biology of Uca rapax (Decapoda: Ocypodidae) in a tropical coastal lagoon, southeast Brazil

Zoologia (Curitiba), 2009
A population of the fiddler crab Uca rapax (Smith, 1870) found in Itaipu Lagoon, southeast Brazil, was sampled monthly from July 2006 to June 2007 in order to study population and reproductive features.

Fiddler Crabs: Ecosystems-Organisms-Molecules [PDF]

American Zoologist, 1984
Organisms live in a complex environ? ment which consists of numerous abiotic and biotic factors. To survive and flourish, organisms must be functionally adapted to respond to any of these factors acting inde? pendently or in combination with one or more other factors. Simplistically, this rela?

Surface morphology and distribution of oropharyngeal taste papillae in sharks and rays (Elasmobranchii, Chondrichthyes): Implications for gustatory sensitivity

Journal of Anatomy, Volume 247, Issue 5, Page 924-952, November 2025.
This study investigates the morphology, abundance, and distribution of taste papillae in the oropharyngeal cavity of a range of elasmobranchs using SEM, histology, and topographic analyses. The interspecific importance of gustation is reflected in quantitative differences in the size, density, and distribution of taste papillae, which have implications

Why do fiddler crabs build chimneys? [PDF]

Biology Letters, 2008
Chimneys are mud mounds built by fiddler crabs that encircle the entrance to their burrow. Their function in many species is unknown. In Uca capricornis , crabs of both sexes and all sizes build chimneys, but females do so disproportionately more often.

Does a lack of juveniles indicate a threat? Understanding body size distributions in a group of long‐lived vertebrates

Journal of Animal Ecology, Volume 94, Issue 10, Page 1962-1982, October 2025.
We used a large dataset to examine turtle size distributions and found that for most species in most areas, distributions are typically skewed towards large adults, with few juveniles present. Therefore, a lack of juveniles does not inherently indicate a declining population, and researchers should be cautious not to over‐interpret adult‐dominated ...

In Vivo Wound Healing and Immune Response Studies of Chitosan Cryogels With Invertebrate Model Organism Galleria mellonella

Biopolymers, Volume 116, Issue 5, September 2025.
– Comparison of chitosan cryogels: single networks versus full‐IPN structure. – Cryogels displaying high swelling degrees more than 2800%, assigned to the interconnected macroporous structure like sponges. – Cryogels with increased mechanical strength, more homogeneous and smaller pores in vivo wound healing and immune response studies of chitosan ...

New record and range extension of the fiddler crab Uca princeps (Smith, 1870) (Brachyura, Ocypodidae) from California, USA

Journal of Crustacean Biology, 2018
The fiddler crab Uca princeps (Smith, 1870) has previously been recorded along the Pacific coast of the Americas from Peru to Mexico. Here we extend its range into the United States, based on photographs posted on the iNaturalist website.
