Host Co-Occurrence and Population Size Explain Genetic Differentiation and Diversity in Seal Lice. [PDF]
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.

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

The Lake Clear (41SM243) Site and Crotalus horridus atricaudatus [PDF]
I fell heir to a collection of prehistoric Caddo sherds from my late Uncle Sam Whiteside and a location on a 7.5’ topographic map labeled Lake Clear. Sam Whiteside during the period from the mid-1950s to the late 1960s was very active in the East Texas ...

One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

Read the free Plain Language Summary for this article on the Journal blog. Abstract The highly threatened African cycad genus Encephalartos faces severe threats such as habitat loss and poaching. In addition, the lack of sexual recruitment due to the absence of pollinators (pollinator collapse) has emerged as another major threat.

The predatory behavior of ants: an impressive panoply of morphological adaptations
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...
