Bacteriophages, or phages, are viruses that infect and replicate within bacterial hosts, playing a significant role in regulating microbial populations and ecosystem dynamics. However, phages from extreme environments such as polar regions remain relatively understudied due to challenges like restricted ecosystem access and low biomass. Understanding the diversity, structure, and functions of [...]

Geographic, seasonal and ontogenetic variations of δ15N and δ13C of Japanese sardine explained by baseline variations and diverse fish movements

Tatsuya Sakamoto, Taketoshi Kodama, Sachiko Horii, et al.

Published: 2023-04-05
Subjects: Life Sciences, Marine Biology

Understanding and predicting variability in the stable isotope ratios of nitrogen and carbon (δ15N and δ13C, respectively) of small pelagic fish is crucial to enable isotopic studies of a variety of marine predators that feed on them. However, because the isotope ratios reflect plastic feeding habits and fish migration in addition to baseline variation, their predictions require a mechanistic [...]

What acoustic telemetry can and can’t tell us about fish biology

Acoustic telemetry (AT) has become ubiquitous in aquatic monitoring and fish biology, conservation and management. Since the early use of active ultrasonic tracking that required researchers to follow at a distance their species of interest, the field has diversified considerably with exciting advances in both hydrophone and transmitter technology. Once a highly specialised methodology however, [...]

The impact of rising temperatures on the prevalence of coral diseases and its predictability: a global meta-analysis

Samantha Burke, Patrice Pottier, Malgorzata Lagisz, et al.

Subjects: Ecology and Evolutionary Biology, Immunology and Infectious Disease, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology, Statistical Models

Coral reefs are under threat from disease as climate change alters environmental conditions. Rising temperatures exacerbate coral disease, but this relationship is likely complex as other factors also influence coral disease prevalence. To better understand this relationship, we meta-analytically examined 108 studies for changes in global coral disease over time alongside temperature, expressed [...]

Record of Halmahera Walking (Hemiscyllium halmahera) Shark in South Morotai

Published: 2022-05-11
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology

The impacts of global change — from shifts in climate to overfishing to land use change — can depend heavily on local abiotic context. Building an understanding of how to downscale global change scenarios to local impacts is often difficult, however, and requires historical data across large gradients of variability. Such data are often not available — particularly in peer reviewed or gray [...]

Extreme heatwave drives topography-dependent patterns of mortality in a bed-forming intertidal barnacle, with implications for associated community structure

Amelia Hesketh, Christopher Harley

Subjects: Animal Sciences, Life Sciences, Marine Biology

Heatwave frequency and intensity will increase as climate change progresses. Intertidal sessile invertebrates, which often form thermally benign microhabitats for associated species, are vulnerable to thermal stress because they have minimal ability to behaviourally thermoregulate. Understanding what factors influence the mortality of biogenic species and how heatwaves might impact their ability [...]
