Effects of Dietary Mannan Oligosaccharides on Growth, Disease Resistance, and Gut Microbiota in Zebrafish

open access: yesAnimal Research and One Health, EarlyView.
Supplementation with mannan oligosaccharides (MOS) enhances growth, disease resistance, antioxidant capacity, and gut microbiota diversity while suppressing inflammation, apoptosis, and strengthening intestinal barrier integrity in zebrafish challenged with LPS or DSS.

Pathophysiological Mechanisms of Emaciation Syndrome in Plectropomus leopardus: Insights From Histology and Transcriptomics

open access: yesAnimal Research and One Health, EarlyView.
Integrated phenotypic, histological, transcriptomic, and validation analyses reveal that emaciation syndrome in Plectropomus leopardus is associated with intestinal structural damage, hepatic metabolic remodeling, and muscle protein degradation, highlighting coordinated multi‐tissue alterations underlying disease progression.

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Morphology of the first larval stage of Macrobrachium brasiliense (Heller, 1868) (Caridea: Palaemonidae)

open access: yesNauplius
In this paper, we describe and illustrate the morphology of the first larval stage of the prawn Macrobrachium brasiliense. Two ovigerous females were obtained in a stream environment, which belongs to Paraná River Basin, Southeastern of Brazil, and were ...

The Megalopa Stage in Grapsidae Crabs (Decapoda, Brachyura), a First Complete Overview Based on New Data from Plankton-Collected Megalopae Identified by DNA Barcodes

open access: yesTaxonomy
The family Grapsidae is composed of 39 species belonging to seven genera. Currently, larval data are known for 24 out of the 39 species, but the megalopa stage remains unknown for the genera Goniopsis, Grapsus, Leptograpsus, and Planes, although ...

Land birds on atolls: diversity, origin, and function

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Hyperactive KIF5A in Neurodegeneration

open access: yesCytoskeleton, EarlyView.
ABSTRACT The highly polarised morphology of neurons and the sheer length of their axons make transport of cargoes throughout the cell a formidable task. Decades of evidence obtained from genetic studies on patients and animal models highlight deficits in axonal transport as a recurrent cause, or early contributing factor, in a plethora of ...

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.

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common
