Forecasting Climate Impacts on Wildlife of the Arid Southwest at Regional and Local Scales Using Downscaled Climate Models

Climate change has emerged as a key environmental concern of the 21st century and a major challenge for land and wildlife managers. Although scientists have made tremendous progress in predicting the impact of climate change on a regional and global scale, drilling down such projections to a locally applicable form has been difficult. A major project of the US Geological Survey's (USGS)...

Cordilleran Flycatcher banding, nestling, and fledgling data from southwestern Colorado, 2009-2018 Cordilleran Flycatcher banding, nestling, and fledgling data from southwestern Colorado, 2009-2018

These tabular data were compiled to assess full annual cycle breeding of the Empidonax occidentalis (Cordilleran Flycatcher). Objectives of our study was to assess facets of the full annual cycle of the Cordilleran Flycatcher. These data represent over nine field seasons of work on the Dolores River in southwestern Colorado with field work conducted from 2009-2018. These data were...

Utilizing artificial nesting platforms as a management tool: Enhancing breeding productivity of Western Flycatchers (Empidonax difficilis occidentalis) in southwestern Colorado and southern Arizona, USA Utilizing artificial nesting platforms as a management tool: Enhancing breeding productivity of Western Flycatchers (Empidonax difficilis occidentalis) in southwestern Colorado and southern Arizona, USA

Artificial nesting substrates have been added around the world for many cavity-nesting bird species, but this has not been undertaken as extensively for crevice-nesting birds. The Western Cordilleran Flycatcher (Empidonax difficilis occidentalis) is a migratory, crevice-nesting flycatcher that is nest-site limited, breeding in higher elevation riparian habitats throughout intermountain...

The importance of Sky Islands in the annual cycle of the Western (Cordilleran) Flycatcher Empidonax occidentalis The importance of Sky Islands in the annual cycle of the Western (Cordilleran) Flycatcher Empidonax occidentalis

For more than a century and a half the Madrean sky islands, a group of 55 mountain ranges that occur from the middle of Arizona to the southern end of Sonora Mexico and rise from the desert floor to 3,000-10,000 feet elevation, have been a Mecca for ornithologists and natural historians. The ornithological literature of the late 19th early 20th centuries is filled with the wonderfully...

Bridging the research-implementation gap in avian conservation with translational ecology Bridging the research-implementation gap in avian conservation with translational ecology

The recognized gap between research and implementation in avian conservation can be overcome with translational ecology, an intentional approach in which science producers and users from multiple disciplines work collaboratively to co-develop and deliver ecological research that addresses management and conservation issues. Avian conservation naturally lends itself to translational...

A tribute to Edward Perry Glenn (1947–2017), who created a legacy of environmental assessment and applications within hydrological processes A tribute to Edward Perry Glenn (1947–2017), who created a legacy of environmental assessment and applications within hydrological processes

This issue of Hydrological Processes is dedicated to Dr. Edward P. Glenn, a frequent contributor to the journal, who suddenly passed away in late 2017. The articles within this volume are by a number of his former co-authors and others who have been greatly influenced by his professional work on hydrological processes.

The transformation of dryland rivers: The future of introduced tamarisk in the U.S. The transformation of dryland rivers: The future of introduced tamarisk in the U.S.

Tamarix spp. (tamarisk or saltcedar), a shrub-like tree, was intentionally introduced to the U.S. from Asia in the mid-1800s. Tamarisk thrives in today’s human-altered streamside (riparian) habitats and can be found along wetlands, rivers, lakes, and streams across the western U.S. In 2001, a biological control agent, Diorhabda spp. (tamarisk leaf beetle), was released in six states, and...
