Future-oriented coastal protection: The utility of living shorelines under changing climatic conditions Open
An accumulation of novel nature-based shoreline management techniques have developed over the past two decades out of the continued need to protect waterfront land combined with an awareness of the relationship between healthy coastal ecos…
Active facilitation of helper dispersal by parents and siblings in the cooperatively breeding acorn woodpecker Open
Offspring that delay dispersal in cooperatively breeding species have been hypothesized to gain direct fitness benefits via parental facilitation—being passively tolerated on their natal territory by their parents—thereby enjoying enhanced…

Density-dependent network structuring within and across wild animal systems Open
High population density should drive individuals to more frequently share space and interact, producing better-connected spatial and social networks [1-4]. Although this theory is fundamental to our understanding of disease dynamics [2,5-8…

Variation in establishment success for American mistletoe [<i>Phoradendron leucarpum</i> (Raf.) Reveal & M.C. Johnst. (Viscaceae)] appears most likely to predict its distribution in Virginia and North Carolina, United States Open
Dispersal limitation and variation in habitat suitability may determine an association of American mistletoe [ Phoradendron leucarpum (Raf.) Reveal & M.C. Johnst. (Viscaceae)] with forested wetlands in Virginia and North Carolina, United S…
Lifetime inclusive fitness effects of cooperative polygamy in the acorn woodpecker Open
Although over 50 y have passed since W. D. Hamilton articulated kin selection and inclusive fitness as evolutionary explanations for altruistic behavior, quantifying inclusive fitness continues to be challenging. Here, using 30 y of data a…
Constructing social networks from automated telemetry data: A worked example using within‐ and across‐group associations in cooperatively breeding birds Open
Advances in data‐logging technologies have provided a way to monitor the movement of individual animals at unprecedented spatial and temporal scales. When used in conjunction with social network analyses, these data can provide deep insigh…
Lifetime reproductive benefits of cooperative polygamy vary for males and females in the acorn woodpecker ( <i>Melanerpes formicivorus</i> ) Open
Cooperative breeding strategies lead to short-term direct fitness losses when individuals forfeit or share reproduction. The direct fitness benefits of cooperative strategies are often delayed and difficult to quantify, requiring data on l…
ACWO_supplmentary_data from Lifetime reproductive benefits of cooperative polygamy vary for males and females in the acorn woodpecker (<i>Melanerpes formicivorus</i>) Open
Raw data for individuals from our long-term data. Has details for all variables used in our analyses.
Are you my baby? Testing whether paternity affects behavior of cobreeder male acorn woodpeckers Open
Natural selection is expected to favor males that invest more in offspring they sire. We investigated the relationship between paternity and male behavior in the acorn woodpecker (Melanerpes formicivorus), a cooperative breeder that lives …
Workflow for constructing social networks from automated telemetry systems Open
1. Advances in datalogging technologies have provided a way to monitor the movement of individual animals at unprecedented spatial and temporal scales, both large and small. When used in conjunction with social network analyses, these data…

Correlates of bird collisions with buildings across three North American countries Open
Collisions with buildings cause up to 1 billion bird fatalities annually in the United States and Canada. However, efforts to reduce collisions would benefit from studies conducted at large spatial scales across multiple study sites with s…
Acorn woodpeckers vocally discriminate current and former group members from nongroup members Open
In species with long-term social relationships, the ability to recognize individuals after extended separation and the ability to discriminate between former social affiliates that have died and those that have left the group but may retur…
Role of Avian Hosts in Spread and Maintenance of Borrelia Spp. and Rickettsia Spp. in Ixodes Spp. Collected off Birds in Southeastern Virginia Open
The role that birds play in the maintenance and the movement of ticks and tick-borne pathogens is an important area of research. The home ranges of resident bird species, and the migratory nature of others, can influence vector-borne disea…
Artificial Perches as a Technique for Enhancing Tropical Forest Restoration: A Case Study From the Dominican Republic Open
Recovering secondary forests on degraded agricultural lands represents a promising opportunity to offset global carbon emissions as well as increasing local biodiversity and ecosystem services. In the insular tropical forests of the Caribb…
Wandering Woodpeckers: Foray Behavior in a Social Bird Open
Nonbreeding helpers in several cooperative breeders birds make cryptic extraterritorial movements to discover dispersal opportunities before leaving their natal territories. Studying the ecology of these secretive forays has been a long-ti…
Does Helping-at-the-Nest Help? The Case of the Acorn Woodpecker Open
Cooperative breeding groups often involve "helpers-at-the-nest"; indeed, such behavior typically defines this intriguing breeding system. In few cases, however, has it been demonstrated that feeding nestlings by helpers, rather than some o…
Urbanization and tick parasitism in birds of coastal southeastern Virginia Open
One of North America's major avian migratory pathways occurs along a large anthropogenically modified coastal region of southeastern Virginia, USA. Because hundreds of avian species migrate along the east coast of North America, understand…

Wild acorn woodpeckers recognize associations between individuals in other groups Open
According to the social intelligence hypothesis, understanding the cognitive demands of the social environment is key to understanding the evolution of intelligence. Many important socio-cognitive abilities, however, have primarily been st…
Artificial light at night confounds broad‐scale habitat use by migrating birds Open
With many of the world's migratory bird populations in alarming decline, broad‐scale assessments of responses to migratory hazards may prove crucial to successful conservation efforts. Most birds migrate at night through increasingly light…
