Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

The use of pelvic fins for benthic locomotion during foraging behavior in Potamotrygon motoro (Chondrichthyes: Potamotrygonidae)

open access: yesZoologia (Curitiba), 2015
Synchronized bipedal movements of the pelvic fins provide propulsion (punting) during displacement on the substrate in batoids with benthic locomotion. In skates (Rajidae) this mechanism is mainly generated by the crural cartilages.

Closing the Gaps: Integrating Biological, Ecological and Taxonomic Data to Support the Identification and Conservation of the Atlantic Pygmy Devil Ray (Mobula hypostoma)

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT The Atlantic pygmy devil ray (Mobula hypostoma) is an endangered mobulid species whose conservation is hindered by taxonomic confusion and significant gaps in ecological and life history knowledge. Here, we present an integrative study that clarifies the species' taxonomic status, updates its distribution and synthesizes new and existing data ...

Modifying Surber sampling technique increases capture of freshwater crabs in African upland streams [PDF]

open access: yes, 2012
We compared 2 methods for sampling the freshwater crab Potamonautes odhneri (Colosi) in Kenyan streams: standard Surber sampling, in which a sample is taken over a period of several minutes; and rapid Surber sampling, in which the process is reduced to ...

Through the Prism of eDNA: Exploring Cryptic Freshwater Bivalves Diversity in a Mega‐Diverse Tropical Environment

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Extensive eDNA sampling in remote tropical rivers revealed six new species, two of which were later confirmed through traditional surveys and formally described. eDNA also captured basin‐scale haplotype diversity, showing that pristine upstream areas harbor both more species and higher genetic diversity than sites affected by human activities ...

Biological characterization of a mid‐water salinity maximum intrusion over the Northeast US Shelf

open access: yesLimnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Salinity maximum intrusions, subsurface layers of anomalously salty and warm continental slope water moving onto the continental shelf along the thermocline, are recurring features over the Northeast US Shelf and represent an important cross‐shelf exchange mechanism.

Brain Morphology and Quantitative Assessment of Sensory Brain Areas in Southern Bluefin Tuna, Thunnus maccoyii (Scombridae, Teleostei)

open access: yesJournal of Comparative Neurology, Volume 534, Issue 4, April 2026.
The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...
