Turning Bonding Into Function: The Emerging Role of the Bioactive Selenium─Metal Motif in Toxicology and Medicinal Chemistry

open access: yesChemistry – A European Journal, EarlyView.
Balancing Act: Se─M bond serving as the fulcrum of the balance scale to compare the different weight of toxicity and therapeutic effects in biological environment. ABSTRACT The synthesis and characterization of organo‐selenium compounds have attracted considerable interest for decades, driven by the search for efficient catalysts and bioinspired ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

MIT/TFE family transcription factors, Mitf and Tfec, redundantly promote pigment cell differentiation and retinal epithelium pigmentation in teleosts

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Transcription factors of the MIT/TFE family—mitfa, mitfb, and tfec—play essential roles in specifying pigment cells derived from neural crest cells in vertebrates. In teleosts, which possess multiple pigment cell types, these factors exhibit partially redundant but largely distinct functions across different pigment lineages.

A Methodological Study of 1D CNN Classification of Marine Mammal Vocalizations with Variable Signal Durations

open access: yesJournal of Marine Science and Engineering
Marine mammal sound classification plays an important role in understanding species behavior, communication, and ecology. Automated classification methods have received increasing attention due to their ability to efficiently process and analyze large ...

Latitudinal effect on the structure of snake–prey interaction networks is mediated by snake species richness

open access: yesEcography, EarlyView.
Despite the growing number of studies on trophic networks in recent decades, there are still important gaps in our understanding of how these networks are structured across broad environmental gradients. These gaps are even greater in some groups of terrestrial vertebrates, such as snakes, requiring a cohesive synthesis of their broader trophic ...

Exploring indirect effects of a classic trophic cascade between urchins and kelp on zooplankton and whales

open access: yesScientific Reports
Kelp forest trophic cascades have been extensively researched, yet indirect effects to the zooplankton prey base and gray whales have not been explored. We investigate the correlative patterns of a trophic cascade between bull kelp and purple sea urchins

Responses of Antarctic seabird populations to past climate change

open access: yesEcography, EarlyView.
Higher‐order predators such as Antarctic seabirds serve as ecological indicators of environmental change and provide a crucial trophic link between marine and terrestrial ecosystems. Despite their prevalence and significance in the Antarctic ecosystem, there is a lack of understanding of the impacts of major regime shifts in paleoclimate on flighted ...

Asymmetric species turnover underpins the latitudinal diversity gradient in the Western Ghats biodiversity hotspot of India

open access: yesEcography, EarlyView.
Latitudinal diversity gradients (LDGs), namely an increase in species richness from higher to lower latitudes, are one of ecology's best documented patterns, yet how the fundamental components of compositional mismatches (i.e. species gains and losses along a gradient) explain these patterns remains poorly understood.
