Extensive Field Observations Throw Light on the Evolution of Mimicry in Camponotus lateralis (Hymenoptera: Formicidae)

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Camponotus lateralis (C, D) mimics regional color morphs of Crematogaster (A, B). Field trips brought insights into ecology, trail sharing, sexual reproduction, colony foundation, nest defense, and predation pressure of this mimetic ant. We found that the mimicry is Batesian and suggest several preadaptations for its evolution.

Ice Shelf Water‐Influenced Fast Ice and Sub‐Ice Platelet Layer Near the Campbell Ice Tongue, Terra Nova Bay

Journal of Geophysical Research: Oceans, Volume 130, Issue 11, November 2025.
Abstract Here, we present the first dedicated in situ measurements of the thickness distributions of fast ice and the sub‐ice platelet layer, formed by supercooled Ice Shelf Water in north Terra Nova Bay, Antarctica. With the objective of inferring source regions and circulation of Ice Shelf Water, we measured fast ice and sub‐ice platelet layer ...

Complete mitochondrial genome of the common silverfish Lepisma saccharina (Insecta: Zygentoma: Lepismatidae)

Mitochondrial DNA. Part B. Resources, 2020
The common silverfish, Lepisma saccharina, is a well-known stored-product insect worldwide, which were obtained from China. The complete mitochondrial genome (GenBank: MT108230) consists of a circular DNA molecule of 15,244 bp with A/T bias of 66.46% AT ...

Sex Differentiation and Long‐Distance Gene Flow in the Elusive Antarctic Fish Aethotaxis mitopteryx

Ecology and Evolution, Volume 15, Issue 8, August 2025.
This genetic study of a rare Antarctic fish, the longfin icedevil (Aethotaxis mitopteryx) investigates population connectivity across the Weddel Sea, revealing little to no differentiation even over vast geographic distances. Unexpectedly, the strongest genetic differentiation is instead observed between male and female fishes, which suggests a ...

Climate Change Impacts on Antarctic Fish Diversity: A Circumpolar Perspective From eDNA Metabarcoding Assessment

Diversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim Recent climate‐driven changes in the Antarctic marine environment, marked by regional differences between West and East Antarctica, may alter ecosystem dynamics. As key components of the food web, fish might reflect these changes. This study examines fish biodiversity patterns across four typical Antarctic seas by integrating eDNA analysis

Population Structure and Life History Connectivity of Antarctic Silverfish (Pleuragramma antarctica) in the Southern Ocean Ecosystem

, 2017
Antarctic silverfish (Pleuragramma antarctica) are the most important pelagic forage fish on the Antarctic continental shelf. They have an exclusively pelagic life history, including cryopelagic eggs and early larvae.

The ecological importance of Antarctic Silverfish [PDF]

, 2016
The Antarctic marine ecosystem is very unique. It supports a fast range of species ranging from phytoplankton to blue whales. Many of these species are endemic, including the Antarctic silverfish Pleuragramma antarcticum which is abundant throughout ...

Understanding early ontogeny and whisker growth dynamics of Weddell seal (Leptonychotes weddellii) pups through stable isotope analysis

Marine Mammal Science, Volume 41, Issue 3, July 2025.
Abstract Stable isotope analysis of animal tissues is a valuable tool for understanding foraging ecology, habitat use, and developmental changes throughout an animal's life. Stable isotope values of whisker segments offer long‐term data on mammalian foraging, as whisker growth incorporates isotopic signals from the diet and reflects dietary shifts ...

Exploring Ant‐Mollusk Interactions: Insights From Southern Spain

Ecology and Evolution, Volume 15, Issue 5, May 2025.
This study reports new data about ant‐mollusk interactions from accidental field observations, a quantitative analysis of the snail shells found in 16 Messor ant nest cleanings, and a qualitative analysis of 51 additional nests of different species. ABSTRACT Ants occupy a great variety of habitats, perform essential ecological roles, and interact with ...

Acoustic deployments reveal Antarctic silverfish under ice in the Ross Sea

, 2018
Antarctic silverfish (Pleuragramma antarctica Boulengcr) are a keystone species in the Ross Sea. Silverfish eggs and larvae are abundant during spring amongst the sub-surface platelet ice in Terra Nova Bay.
