View article: Non‐Native Bird Populations Respond Differently to Their Environment and Exhibit Shifts in Ecological Niche Limits Across Continents
Non‐Native Bird Populations Respond Differently to Their Environment and Exhibit Shifts in Ecological Niche Limits Across Continents Open
Aim The degree to which species' niches remain stable over space and time–the niche conservatism hypothesis–is critical for predicting species' responses to environmental change. Tests of this hypothesis typically focus on changes in niche…

Forward steps, lingering gaps: gender representation among distinguished speakers at professional conferences Open
Plenary speakers serve as role models for early-career scholars, and these talks advance the speakers’ careers while celebrating the important scientific contributions of women. Professional conferences are an ideal venue for assessing pro…

Considering Multiecosystem Trade‐Offs Is Critical When Leveraging Systematic Conservation Planning for Restoration Open
Conservationists are increasingly leveraging systematic conservation planning (SCP) to inform restoration actions that enhance biodiversity. However, restoration frequently drives ecological transformations at local scales, potentially res…

Agricultural mosaics offer nesting habitat to dabbling ducks in the arid Intermountain West of the United States Open
The debate over the best agricultural practices for biological conservation often focuses on the degree to which agricultural lands should be interspersed with desirable habitat versus protecting lands entirely from production. It is impor…

Sexual harassment disproportionately affects ecology and evolution graduate students with multiple marginalized identities in the United States Open
Sexual harassment within academic institutions has profound impacts that may lead to the attrition of groups historically excluded from the biological sciences and related disciplines. To understand sexual harassment's effects on vulnerabl…

Land cover differentially affects abundance of common and rare birds Open
While rare species are vulnerable to global change, large declines in common species (i.e., those with large population sizes, large geographic distributions, and/or that are habitat generalists) also are of conservation concern. Understan…

Conservation Design and Stewardship Guidelines for Local Land-Use Regulations Open
Our goal is to support and encourage land-use planners, decision makers and conservation scientists and practitioners to participate in local land-use policy by providing them with guidelines that translate their scientific knowledge into …

Synergies and Trade-Offs in Reducing Impacts of Unconventional Oil and Gas Development on Wildlife and Human Health Open
With growing evidence of widespread health and environmental impacts from oil and gas activity, localities and states are beginning to develop protective measures. Interdisciplinary approaches that integrate across human, wildlife, domesti…

A Mechanistic Framework for Understanding the Effects of Climate Change on the Link Between Flowering and Fruiting Phenology Open
Phenological shifts are a widely studied consequence of climate change. Little is known, however, about certain critical phenological events, nor about mechanistic links between shifts in different life-history stages of the same organism.…
View article: Strengths and shortcomings of habitat exchange programs for species conservation
Strengths and shortcomings of habitat exchange programs for species conservation Open
Habitat exchange programs, a form of biodiversity offsetting, aim to compensate for negative impacts in one area by conservation in another. A newer subset of habitat exchange programs includes programs that have three distinct characteris…

Juggling parenthood and ornithology: A full lifecycle approach to supporting mothers through the American Ornithological Society Open
The understanding that motherhood impacts career paths is so pervasive among early-career scientists that some feel they must choose parenthood or a career. The penalties associated with motherhood can contribute to the “leaky pipeline,” w…
View article: Tradeoffs of using place‐based community science for urban biodiversity monitoring
Tradeoffs of using place‐based community science for urban biodiversity monitoring Open
Community science, the enlisting of volunteers to collect biodiversity data, is now common and widespread. In theory, the benefits of this model are complementary: community science programs produce useful datasets while engaging the publi…
View article: The total dispersal kernel: a review and future directions
The total dispersal kernel: a review and future directions Open
The distribution and abundance of plants across the world depends in part on their ability to move, which is commonly characterized by a dispersal kernel. For seeds, the total dispersal kernel (TDK) describes the combined influence of all …
View article: Advancing an interdisciplinary framework to study seed dispersal ecology
Advancing an interdisciplinary framework to study seed dispersal ecology Open
Although dispersal is generally viewed as a crucial determinant for the fitness of any organism, our understanding of its role in the persistence and spread of plant populations remains incomplete. Generalizing and predicting dispersal pro…
View article: Employing plant functional groups to advance seed dispersal ecology and conservation
Employing plant functional groups to advance seed dispersal ecology and conservation Open
Seed dispersal enables plants to reach hospitable germination sites and escape natural enemies. Understanding when and how much seed dispersal matters to plant fitness is critical for understanding plant population and community dynamics. …

Ecological and social consequences of bison reintroduction in Colorado Open
Bison were instrumental in shaping North America's Great Plains. Interest in restoring this iconic species and their ecological role in grassland ecosystems is rapidly gaining momentum. To evaluate the potential for bison to enhance habita…

An introduced plant affects aquatic-derived carbon in the diets of riparian birds Open
Non-native plants can impact riparian ecosystem function through diverse terrestrial and aquatic pathways, with cascading effects on food webs. Invasion-mediated vegetation changes can depress terrestrial arthropod communities and alter ar…
