Host Co‐Occurrence and Population Size Explain Genetic Differentiation and Diversity in Seal Lice

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT We studied the drivers of population‐genetic structuring and genetic diversity in specialist parasites based on whole‐genome resequencing data from 82 Echinophthirius horridus seal louse individuals sampled from 12 ecologically and behaviourally different phocine seal species, subspecies and populations across the Holarctic.

Performance Advantages of Labyrinth Weir

International Journal of Innovative Technology and Exploring Engineering, 2019
Weir is a very common structure across water courses to control flow and to release surplus water from water bodies. Simple straight weirs are less efficient compared to labyrinth weir where the weir length is increased by folds. In this research, experiments were conducted in the laboratory to find the increase in discharge due to labyrinth or ...

Plant Cognition—A Methodological Primer: Theories, Methods and Challenges

Philosophy Compass, Volume 20, Issue 12, December 2025.
ABSTRACT Part I: What counts as cognition, and how can it be studied in organisms without nervous systems? The emerging field of plant cognition confronts these questions by integrating philosophy, plant science and comparative psychology. This article provides a methodological primer on the field.

Into the Deep: Origins and Evolution of Northeastern Pacific Ocean Tuna (Thunnus spp.) Fisheries

Fish and Fisheries, Volume 26, Issue 6, Page 1164-1179, November 2025.
ABSTRACT People have had a profound influence on Earth's biodiversity for millennia, culminating in Anthropocene environmental degradation and the modern biodiversity crisis. While the scale and extent of people's long‐term influence on Earth's biodiversity in terrestrial and nearshore marine ecosystems are relatively well studied, there are ...

Comparison of Hydraulic Efficiency of Arched Non-linear Weirs in Plan Using GEP and SVM Neural Networks [PDF]

علوم آب و خاک, 2023
Non-linear weirs meanwhile economic advantages, have more passing flow capacity than linear weirs. These weirs have higher discharge efficiency with less free height upstream compared to linear weirs by increasing the length of the crown at a certain ...

Repeatable Genomic Outcomes Along the Speciation Continuum: Insights From Pine Hybrid Zones (Genus Pinus)

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Hybridization is a widespread evolutionary process and a key source of evolutionary novelty. Despite intensive study, the extent to which hybridization is deterministic and repeatable, particularly in recurrent contact events involving the same species under varying ecological conditions, remains unclear. Here, we investigated three replicated

Tracking Long‐Term Trends in Sockeye Salmon (Oncorhynchus nerka) Population Dynamics Using Sterol and Stanol Biomarkers in Lake Sediments

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.
Abstract We analyzed biomarkers, including sterols, stanols, and δ15N, in sediment cores from lakes with well‐documented sockeye salmon return histories. Our goal was to improve estimates of past changes in salmon escapement, that is, the population that return to their freshwater nursery lakes, inferred using sediment biogeochemical markers ...

Age‐Dependent Effects of Loss of Contactin‐Associated Protein‐Like 2, an Autism‐Associated Gene, on the Acquisition and Recall of Fear Memory

Autism Research, Volume 18, Issue 5, Page 1011-1023, May 2025.
ABSTRACT The contactin‐associated protein‐like 2 (Cntnap2) gene is relevant to autism spectrum disorder (ASD), which is associated with age‐specific structural alterations in limbic brain regions. The Cntnap2 gene encodes for the contactin‐associated protein‐like 2 (CASPR2) protein, and CASPR2 protein levels are high in the amygdala, a limbic region ...

An Experimental Study of the Discharge of the Length Increase Effect on the Composite Trapezoidal Labyrinth Spillway

علوم آب و خاک, 2019
Labyrinth weirs are the economic structures to increase the weir output efficiency in limited widths, which can be seen in the plane f trapezoidal and triangular forms.

MISFITS, POWER, AND HISTORY: RETHINKING ABILITY THROUGH AN ANIMAL LENS

History and Theory, Volume 64, Issue 1, Page 75-95, March 2025.
ABSTRACT In this article, we construct a critical history of “ability” by focusing on the specific case study of dark‐dwelling animals and the ways in which they have been understood over the course of modernity. Such creatures were frequently the subjects of assumptions and judgments about what they could and could not do.
