Bayesian change point analysis of abundance trends for pelagic fishes in the upper San Francisco Estuary.
TLDR
Examination of trends in abundance of four pelagic fish species in the upper San Francisco Estuary over 40 years using Bayesian change point models found no selected covariates could explain statistically the post-2000 change points for any species. Expand
Collapse of an avifauna: climate change appears to exacerbate habitat loss and degradation
Aim  We characterized changes in reporting rates and abundances of bird species over a period of severe rainfall deficiency and increasing average temperatures. We also measured flowering inExpand
Anthropogenic disturbance in tropical forests can double biodiversity loss from deforestation
Concerted political attention has focused on reducing deforestation, and this remains the cornerstone of most biodiversity conservation strategies. However, maintaining forest cover may not reduceExpand
AN INTEGRATIVE APPROACH TOWARDS UNDERSTANDING ECOLOGICAL RESPONSES TO DAM REMOVAL: THE MANATAWNY CREEK STUDY
ABSTRACT: Dam removal has been proposed as an effective method of river restoration, but few integrative studies have examined ecological responses to the removal of dams. In 1999, we initiated anExpand
Effects of removal of a small dam on downstream macroinvertebrate and algal assemblages in a Pennsylvania stream
TLDR
The results and other studies of dam removal suggest that downstream sedimentation following dam removal can reduce densities of macroinvertebrates and benthic algae and may reduce benthi diversity, but for small dams such impacts may be relatively minor and will usually be temporary. Expand
How pervasive is biotic homogenization in human-modified tropical forest landscapes?
TLDR
Concerns that β-diversity has been underestimated as a driver of biodiversity change are supported and underscore the importance of maintaining a distributed network of reserves, including remaining areas of undisturbed primary forest, but also disturbed and regenerating forests, to conserve regional biota.

Time lags in provision of habitat resources through revegetation
Broadscale land use changes are occurring rapidly in rural landscapes worldwide, within which revegetation with native plant species to increase the area of suitable habitat is a key activity.Expand
Analysis of pelagic species decline in the upper San Francisco Estuary using multivariate autoregressive modeling (MAR).
TLDR
The results were relatively robust with respect to the form of stock-recruitment model used and to inclusion of subsidiary covariates but may be enhanced by using detailed state-space models that describe more fully the life-history dynamics of the declining species. Expand
Avifaunal disarray due to a single despotic species
TLDR
The evidence for widespread assemblage-level phase shifts across eastern Australia is reviewed, triggered partly by anthropogenic habitat alteration and mediated by a native, despotic bird: the noisy miner Manorina melanocephala. Expand
Forest structure, habitat and carbon benefits from thinning floodplain forests: Managing early stand density makes a difference
Abstract Forest ecosystems are increasingly expected to produce multiple goods and services, such as timber, biodiversity, water flows, and sequestered carbon. While many of these are not mutuallyExpand
