Pollination and other ecosystem services produced by mobile organisms: a conceptual framework for the effects of land-use change.
Many ecosystem services are delivered by organisms that depend on habitats that are segregated spatially or temporally from the location where services are provided. Management of mobile organismsExpand

A meta-analysis of bees' responses to anthropogenic disturbance.
Pollinators may be declining globally, a matter of concern because animal pollination is required by most of the world's plant species, including many crop plants. Human land use and the loss ofExpand

Are urban parks refuges for bumble bees Bombus spp. (Hymenoptera: Apidae)?
Declines in bee populations have been documented in several parts of the world. Bees are dependent upon flowering plants for resources, and flowering plants often depend upon bees for pollinationExpand

Patch and landscape factors shape community assemblage of bumble bees, Bombus spp. (Hymenoptera: Apidae), in montane meadows
Abstract Understanding the scale at which habitat influences species richness in terrestrial ecosystems is central to both ecology and conservation biology [Wettstein, W., Schmid, B., 1999.Expand

Avian body size changes and climate change: warming or increasing variability?
There has been a growing interest in whether established ecogeographical patterns, such as Bergmann’s rule, explain changes in animal morphology related to climate change. Bergmann’s rule has oftenExpand

The role of geography and ecology in shaping the phylogeography of the speckled hummingbird (Adelomyia melanogenys) in Ecuador.
The Andes of South America contain one of the richest avifaunas in the world, but little is known about how this diversity arises and is maintained. Variation in mitochondrial DNA and morphologyExpand

Detecting insect pollinator declines on regional and global scales.
Recently there has been considerable concern about declines in bee communities in agricultural and natural habitats. The value of pollination to agriculture, provided primarily by bees, is >$200Expand

The influence of urban park characteristics on ant (Hymenoptera, Formicidae) communities
As rapid urbanization continues, existing natural areas within urban zones will play a critical role in safeguarding remaining biodiversity. Ants are an integral part of almost every terrestrialExpand

Mining photo-sharing websites to study ecological phenomena
We show that by analyzing the tags and image features of geo-tagged, time-stamped photos we can measure and quantify the occurrence of ecological phenomena including ground snow cover, snow fall and vegetation density. Expand
