Estimating the proportion of a beluga population using specific areas from connectivity patterns and abundance indices

Ecosphere, 2021
An understanding of habitat use and connectivity is key to preserving wildlife habitat integrity. In this study, we present an innovative approach to habitat connectivity and quantitative assessment of their use that is applicable to any terrestrial or ...

Two Routes to Land: Genomic Underpinnings of Parallel Aerial Egg Deposition in Aquatic Old‐World Pila and New‐World Pomacea (Ampullariidae)

Advanced Science, EarlyView.
Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Performance and retention of lightweight satellite radio tags applied to the ears of polar bears (Ursus maritimus)

Animal Biotelemetry, 2017
Background Satellite telemetry studies provide information that is critical to the conservation and management of species affected by ecological change. Here we report on the performance and retention of two types (SPOT-227 and SPOT-305A) of ear-mounted ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Trans-Atlantic movements of Atlantic white-sided dolphins, Leucopleurus acutus

Frontiers in Marine Science
Atlantic white-sided dolphins are wide-ranging and abundant cetaceans of the North Atlantic, yet their movements remain poorly understood. Using satellite telemetry, we tracked 23 dolphins tagged in the Faroe Islands to investigate their movement ...

An Overview of Marine Mammals in Eastern Indonesia 2016: Implications for Marine Mammals Research and Conservation

E3S Web of Conferences, 2018
Eastern Indonesia is known as the center of marine biodiversity of the world as well as habitat and marine mammal migration path. Not all marine mammal events in eastern Indonesia are well documented.

A Modular PLUG‐IN Photosynthetic Chassis With Tunable Thermal Control for Mammalian Systems

Advanced Science, EarlyView.
This work establishes a “plug‐in” chassis compatible with mammalian systems that synchronizes growth, production, and cell‐wall re‐configuration, providing a versatile platform for photosynthetic bioproduction and microalgal synthetic biology. ABSTRACT Microalgae are promising photosynthetic platforms for high‐value compounds, yet their industrial use ...

Brain transcriptomes of harbor seals demonstrate gene expression patterns of animals undergoing a metabolic disease and a viral infection [PDF]

PeerJ, 2016
Diseases of marine mammals can be difficult to diagnose because of their life history and protected status. Stranded marine mammals have been a particularly useful resource to discover and comprehend the diseases that plague these top predators ...

Integrative Omics Analysis Reveals the Regulation of Hypoxia Tolerance in Large Yellow Croaker (Larimichthys crocea) via the Lipoic Acid Synthase (lias) Gene

Advanced Science, EarlyView.
Lipoic acid synthase (lias) can regulate α‐KG levels through lipoylation, thereby negatively regulating HIF‐1α protein levels via PHD under hypoixa. The Hap2 allele of lias exhibits lower expression levels than Hap1, leading to the accumulation of more HIF‐1α protein and thereby enhancing hypoxia tolerance. ABSTRACT Hypoxia stress seriously affects the
