Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Shallow-Water Coral Communities Support the Separation of Marine Ecoregions on the West-Central Florida Gulf Coast

open access: yesFrontiers in Ecology and Evolution, 2020
Florida’s west coast is a 170,000 km2 bedrock shelf (west Florida shelf, WFS) comprised of north-south discontinuous carbonate outcroppings extending more than 200 km from the intertidal zone to a depth of 200 m.

The impacts of physical processes on oxygen variations in the North Sea-Baltic Sea transition zone [PDF]

open access: yesOcean Science, 2012
The bottom water of the North Sea–Baltic Sea transition zone suffers from seasonal hypoxia, usually during late summer and autumn. These hypoxic events are critical for the benthic ecosystems and the concentration of dissolved oxygen is an important ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Phytobenthic communities of the Barents Sea Arctic zone and climate change

open access: yesVestnik MGTU, 2018
The study of species structure of benthic seaweeds populations in plant communities of the coastal Arctic zone of Arctic archipelagoes of the Barents Sea on the basis of expeditionary works' materials has been carried out.

Bioregionalization in a data-poor situation: Mapping of Uruguayan marine benthic regions

open access: yesFrontiers in Marine Science, 2023
IntroductionThe Uruguayan Exclusive Economic Zone (U-EEZ) is still lacking a technically sound and institutionally agreed system for classifying marine benthic ecosystems. This fact, added to the growing anthropic pressure marine ecosystems face in the U-

Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.

Effects of waste waters on benthic macrofauna of sandy beaches in Todos Santos Bay

open access: yesCiencias Marinas, 1992
The seasonal study of the benthic macrofauna in Todos Santos Bay shows the effects of waste waters on the benthic communities of the intertidal zone. The analysis of the data separates the fauna into two main associations: one made up of the populations

Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?

open access: yesThe Depositional Record, EarlyView.
This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

ROV’s Video Recordings as a Tool to Estimate Variation in Megabenthic Epifauna Diversity and Community Composition in the Guaymas Basin

open access: yesFrontiers in Marine Science, 2020
Patterns in benthic megafauna diversity in littoral and intertidal zones in the Gulf of California have been associated with both habitat heterogeneity and substrate type.
