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

Biological Reviews, EarlyView.
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 ...

An ecological and methodological assessment of benthic gross primary production in northern lakes

Ecosphere, 2022
Benthic gross primary production (GPP) is often the most important part of aquatic food webs in northern lakes, which are gradually warming and receiving increased terrestrial colored dissolved organic carbon loadings due to global change.

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Transport of benthic diatoms across the continental shelf off southern Baja California Peninsula

Ciencias Marinas, 2004
Material collected with a time-series sediment trap moored in San Lázaro Basin, near the NE Pacific upwelling zone off Bahía Magdalena, Baja California Sur (Mexico), from August to November 1996 and December 1997 to June 1998, revealed temporal changes ...

Toxic Metals in Dried Marine Fish and Implications for Human Health in Bangladesh and Exporting Countries

Food Safety and Health, EarlyView.
This study assessed toxic metals in five dried marine fish species from Bangladesh. Although most metals were within safe limits, chromium (Cr) consistently exceeded FAO/WHO standards, especially at Kuakata Beach. The findings highlight localized contamination hotspots and species‐specific bioaccumulation, while risk assessment supports the safety and ...

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Benthic Species Distribution Linked to Morphological Features of a Barred Coast

Journal of Marine Science and Engineering, 2019
The composition of benthic species communities in the nearshore zone is closely related to the hydrodynamic and morphodynamic conditions. Sustainable management of the coastal ecosystem requires knowledge about the natural dynamics as well as human ...

Shift in polar benthic community structure in a fast retreating glacial area of Marian Cove, West Antarctica

Scientific Reports, 2021
Glacier retreat is a major long-standing global issue; however, the ecological impacts of such retreats on marine organisms remain unanswered. Here, we examined changes to the polar benthic community structure of “diatoms” under current global warming in

An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

Limnology and Oceanography: Methods, EarlyView.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Foraminifera from the Campanian–Maastrichtian of the Miriri Sub-Basin, Paraíba Basin, Brazil: implications for biostratigraphy and paleoenvironmental reconstruction [PDF]

Anais da Academia Brasileira de Ciências
This study investigates the core RT-01-PB from the Miriri Sub-Basin, Paraíba Basin, analyzing planktic and benthic foraminifera from the upper Campanian to lower Maastrichtian. The strata belong to the Itamaracá and Gramame formations. Lithostratigraphic,
