Concerns have been raised that invertebrate pollinators of crops and wild plants are in
decline as a result of modern agricultural practices, habitat degradation, and introduced …

Pollinators provide essential ecosystem services, and declines in some pollinator
communities around the world have been reported. Understanding the fundamental …

Urbanization within the Tucson Basin of Arizona during the past 50+ years has fragmented
the original desert scrub into patches of different sizes and ages. These remnant patches …

Widespread evidence of pollinator declines has led to policies supporting habitat restoration
including in agricultural landscapes. Yet, little is yet known about the effectiveness of these …

Although specialization in species interactions has usually been equated to reciprocal
specialization, asymmetric specialization (ie, a specialist interacting with a generalist) is also …

With the growing interest in pollinator conservation, a need has emerged for a simple,
unbiased method to reliably sample local bee faunas. One method, pan-trap**, has …

Few studies directly address the consequences of habitat fragmentation for communities of
pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes) …

Changes in flower-visiting insect populations or communities that result from human impacts
can be documented by measuring spatial or temporal trends, or by comparing abundance or …

We compared the species richness and abundance of pollinator (Hymenoptera: Apoidea)
communities in two seasons (September 1998 and April 1999) among four types of urban …

To slow the rate of global species loss, it is imperative to understand how to restore and
maintain native biodiversity in agricultural landscapes. Currently, agriculture is associated …
