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 ...

Boreas, EarlyView.Palaeoenvironmental records along the eastern coast of Thailand remain sparse, with only a few studies attempting to reconstruct past climatic and environmental conditions. However, additional palaeoenvironmental, palaeoclimatic and sea‐level records are needed to improve our understanding of coastal evolution and local environmental changes.

Conservation Science and Practice, EarlyView.Yellow crazy ants (Anoplolepis gracilipes; YCA) are widespread invaders of islands across the Pacific and Indian Oceans. We investigated the ecological preferences and impacts of this species on a Polynesian atoll. We show that even at low abundances, this species can have important impacts on the fauna, including seabirds, and require management ...

Gravel galore: Impacts of clear-cut logging on salmon and their habitats [PDF]
, 2002 Timber harvest may have both direct and indirect effects on salmon, and with a few exceptions those effects result in lowered survival of salmon in their stream habitats compared with unlogged forest (Hicks et al. 1991b).

Integrating ecological feedbacks across scales and levels of organization
Ecography, EarlyView.In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.
