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

Animal 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 ...

Recent progress in genetic transformation of four Pinus spp.

, 2007
Advances in conifer tissue culture and genetic transformation offer new opportunities in the field of genetic engineering. Genetic transformation is an important tool for breeders because it allows them to introduce valuable genes that might otherwise be difficult to integrate into elite genotypes.

Polyethylene tarping elevates temperature and reduces emergence of Phloeosinus punctatus LeConte (Coleoptera: Curculionidae) from giant sequoia debris piles

Agricultural and Forest Entomology, EarlyView.
Phloeosinus bark beetles may build up large populations in branch debris piles and stress giant sequoia trees. Covering debris piles with polyethylene sheeting increased the mean ambient temperature in piles and reduced beetle emergence. This was mediated by canopy structure, where ambient temperatures were further elevated under open canopies.

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty

Conservation Biology, EarlyView.
Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...

Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer

Ethology, EarlyView.
Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat‐driven risk perception and reliance on spatial avoidance over increased alertness.

First Report of <i>Ophiostoma clavatum</i> and <i>Fusarium verticillioides</i> Associated With <i>Ips acuminatus</i>-Infested Scots Pine in Western Ukraine. [PDF]

Plant Environ Interact
This study provides the first record of Ophiostoma clavatum associated with Ips acuminatus in Ukraine, and the first evidence of Fusarium verticillioides coexisting with ophiostomatoid fungi in infested Scots pines. This fungal association may contribute to the decline of Scots pine stands.

Bee community and trait‐based responses to fire in a Mediterranean landscape

Insect Conservation and Diversity, EarlyView.
Fire drives a short‐term increase in bee abundance and diversity, despite its strong negative impact on floral resources. Acting as an environmental filter, fire shapes bee communities as increased post‐fire fine‐scale heterogeneity favors bees with specific functional traits such as ground‐nesting and generalist species.
