The use of nectar feeders has grown a lot as a result of people wanting to attract hummingbirds to their gardens. This has caused an increment in the density and diversity of these birds in urban and suburban habitats. The feeders not only repre[...]

Extinctions are often the result of multiple factors that are difficult to disentangle and so methods for identifying simple and combined types of extinctions are valuable for both basic and applied ecology. We applied a modification of variance[...]

Ground-nesting birds have declined world-wide, probably partly due to high nest predation. A non-lethal method for decreasing predation uses protective cages at nests. Tests have mainly looked at the effect of such nest exclosures on hatching su[...]

Agri-environment schemes (AES) are a key tool in attempts to reverse long-term declines in farmland biodiversity within the European Union (EU). Approximately 20% of EU farmland is under AES agreement, at a cost of over E24 billion between 1994 [...]

Agricultural landscapes are the dominating landscape types in many parts of the world. Land-use intensification and spatial homogeneity are major threats to biodiversity in these landscapes. Thus cost-effective strategies for species conservatio[...]

General guidelines available to revegetation. planners focus on the spatial context and dimensions of the revegetated site. However, site-specific habitat factors can have over-arching importance for habitat value, especially where interactions [...]

We studied the interaction between seabirds and warp cables in the high-seas Argentine hake Merluccius hubbsi trawl fishery operating in Golfo San Jorge, Argentina, and tested the efficacy of a simple mitigation measure designed to reduce mortal[...]

It has been argued that the wide-scale provision of artificial surface water in semi-arid savannas may result in homogenisation of foraging regimes, compromising biodiversity and ecosystem resilience. This is the first landscape-scale study inve[...]

The grasslands and heathlands of Martha's Vineyard Island, Massachusetts provide habitat for unusual, rare, and endangered species. Currently, these globally rare ecosystems exist as fragments on the southern coast of the island within a matrix [...]

Coral reefs are popular with ecotourists, but the impact of divers on reefs is cause for concern. In this study, we assessed the damage to corals caused by divers seeking cryptic but charismatic fish such as seahorses (family Syngnathidae) and f[...]

I apply a comparative, functional group approach to coastal sandplain grassland taxa in order to examine whether rare plant species share certain aspects of rarity and life history characters that are distinct from their more common, co-occurrin[...]

Changes to land use and disturbance frequency threaten disturbance-dependent Lepidoptera within sandplain habitats of the northeastern United States. The frosted elfin (Callophrys irus) is a rare and declining monophagous butterfly that is found[...]

The factors that influence the invasion of natural habitats by normative plants remain poorly understood. We investigated abiotic, biotic, and human influences on the distribution and abundance of normative species in coastal upland habitats of [...]

Both disturbance history and previous land use influence present-day vegetation and soils. These influences can have important implications for conservation of plant communities if former disturbance and land use change species abundances, incre[...]

Rare plants in coastal New England sandplains are often restricted to anthropogenically disturbed sites including plowed and mowed firelanes at the Manuel F. Correllus State Forest on Martha's Vineyard. Little is known about pre-colonial rare pl[...]
