Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

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)

open access: yesIntegrative 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 ...

Effects of blockage and relative coarseness on clear water bridge pier scour

open access: yes, 2014
Clear water pier scour experiments were conducted in the laboratory to analyze the effects that blockage ratio and relative coarseness have on bridge pier scour depth.

Spatial Patterns of Avian Stable Isotopes Reveal Ecological Impacts of Climate and Land‐Use Change

open access: yesIntegrative Zoology, EarlyView.
Increased feather δ15N values with pasture coverage reveal an elevated baseline δ15N in grazing landscapes, while broader isotopic niches in farmland habitats reflect agricultural expansion's significant influence on resource use patterns of the avian community.

Burrow Persistence and Spatial Distribution of Federally and State‐Protected Gopher Tortoise (Gopherus polyphemus) Populations in Southwest Alabama

open access: yesAnimal Conservation, EarlyView.
The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...
