What Are the Phylogenetic Limits to Pollinator Diversity?
ABSTRACT Although huge progress has been made over the past 200 years in identifying the diversity of pollinators of angiosperms and other plants, new discoveries continue to be made each year, especially in tropical areas and in the fossil record. In this perspective article I address the following questions: Just how diverse are the pollinators and ...

Potential expanded pollinator distributions in North America under future climate
Most pollinator species, including monarch butterflies, may gain potential climate space in the future. Shifting to new locations is an additional challenge of climate change. Management, restoration and citizen participation to provide resources and reduce stressors are ecological solutions.

Colletidae nesting biology (Hymenoptera: Apoidea) [PDF]
Colletidae are unique among bees for certain aspects of their nesting biology. In this review, attributes of colletid nesting are evaluated and discussed in light of a novel phylogenetic hypothesis for the family. Some predictions made about evolution of certain traits, such as the cocoon-spinning behavior of Diphaglossinae, are confronted with ...
