Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

Integrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...

Animal‐Mediated Dispersal and Clonal Growth Drive Prunus cerasus Invasion in Andean Temperate Forest

Integrative Zoology, EarlyView.
Prunus cerasus reproduces by clonality and by seed dispersal and germination. P. cerasus is invading Patagonian protected areas. The relative relevance of germination and clonal reproduction changes along the time of P. cerasus arrival at a site. Seed dispersal by foxes is primarily responsible for the spread of P. cerasus to new areas.

Conserving Rodent Pests in Transition Toward Endangered Status

Integrative Zoology, EarlyView.
Rodent control invariably takes place in the context of ecosystems heavily modified by agriculture. Together, they are potent drivers of rodent decline and endangerment. Nineteen percent of 2349 rodent species evaluated in the IUCN Red List of threatened species are of some conservation concern.

Land, Gendered Labor, and Empire‐Making in Central Sudan

American Anthropologist, EarlyView.
ABSTRACT This article offers an analysis of Gulf‐Arab and more specifically Emirati empire‐making in central Sudan, by focusing ethnographic attention on an Emirati‐owned farm in the Gezira region as a key site of capitalist extraction and imperial ambition.

Island invertebrate responses to single‐ and multi‐species invasive rodent eradications

Conservation Science and Practice, EarlyView.
Eradications of rodents on islands are a powerful tool for conservation, but rarely are the responses of invertebrates quantified post‐eradication, despite being the preferred prey of mice. Here we analyzed pre‐ and post‐eradication invertebrate survey results for two sub‐Antarctic islands where mice had recently been eradicated; Antipodes Island where

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Mesophotic octocoral larval settlement preferences and behaviors

Restoration Ecology, EarlyView.
Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...
