Annual variation in long-distance dispersal driven by breeding and non-breeding season climatic conditions in a migratory bird

Rushing, Clark S.; Dudash, Michele R.; Studds, Colin E.; Marra, Peter P. (2015)

Long-distance dispersal is a fundamental process in ecology and evolution but the factors that influence these movements remain poorly understood in most species. We used stable hydrogen isotopes to quantify the rate and ...

Call for a Paradigm Shift in the Genetic Management of Fragmented Populations

Ralls, Katherine; Ballou, Jonathan D.; Dudash, Michele R.; Eldridge, Mark D. B.; Fenster, Charles B.; Lacy, Robert C.; Sunnucks, Paul; Frankham, Richard (2018)

Thousands of small populations are at increased risk of extinction because genetics and evolutionary biology are not well-integrated into conservation planning-a major lost opportunity for effective actions. We propose ...

Characterization of the mating system of a native perennial tetraploid herb, Silene stellata

Zhou, Juannan; Zimmer, Elizabeth A.; Fenster, Charles B.; Dudash, Michele R. (2018)

Premise of the Study Nursery pollination systems can range from obligate to facultative. In a system where generalists provide substantial pollination service, an important question is whether the cost of seed predation ...

Comparison of population genetic structures of the plant Silene stellata and its obligate pollinating seed predator moth Hadena ectypa

Zhou, Juannan; Dudash, Michele R.; Zimmer, Elizabeth A.; Fenster, Charles B. (2018)

Development of Highly Variable Microsatellite Markers for the Tetraploid Silene stellata (Caryophyllaceae)

Zhou, Juannan; Dudash, Michele R.; Fenster, Charles B.; Zimmer, Elizabeth Anne (2016)

Premise of the study: We designed and tested microsatellite markers for the North American native species Silene stellata (Caryophyllaceae) to investigate its population genetic structure and identify selection on floral ...

Food limitation modulates the endogenous control of spring migratory behavior in a captive long-distance migratory bird population

Stanley, Calandra Q.; Hallager, Sara H.; Dudash, Michele R.; Marra, Peter P. (2022)

Genetic diversity and population structure among native, naturalized, and invasive populations of the common yellow monkeyflower, Mimulus guttatus (Phrymaceae)

Zimmer, Elizabeth A.; Berg, Jason A.; Dudash, Michele R. (2023)

An ongoing controversy in invasion biology is the prevalence of colonizing plant populations that are able to establish and spread, while maintaining limited amounts of genetic variation. Invasive populations can be ...

Genetic Management of Fragmented Animal and Plant Populations

Frankham, Richard; Ballou, Jonathan D.; Ralls, Katherine; Eldridge, Mark D. B.; Dudash, Michele R.; Fenster, Charles B.; Lacy, Robert C.; Sunnucks, Paul (2017)

Habitat features and long-distance dispersal modify the use of social information by a long-distance migratory bird

Rushing, Clark S.; Dudash, Michele R.; Marra, Peter P. (2015)

1.The processes by which individuals select breeding sites have important consequences for individual fitness as well as population- and community-dynamics. Although there is increasing evidence that many animal species ...

Implications of different species concepts for conserving biodiversity

Frankham, Richard; Ballou, Jonathan D.; Dudash, Michele R.; Eldridge, Mark D. B.; Fenster, Charles B.; Lacy, Robert C.; Mendelson, Joseph R., III; Porton, Ingrid J.; Ralls, Katherine; Ryder, Oliver A. (2012)

The ~26 definitions of species often yield different numbers of species and disparate groupings, with financial, legal, biological and conservation implications. Using conservation genetic considerations, we demonstrate ...

A Practical Guide for Genetic Management of Fragmented Animal and Plant Populations

Frankham, Richard; Ballou, Jonathan D.; Ralls, Katherine; Eldridge, Mark; Dudash, Michele R.; Fenster, Charles B.; Lacy, Robert C.; Sunnucks, Paul (2019)

The biological diversity of the planet is being rapidly depleted due to the direct and indirect consequences of human activity. As the size of wild animal and plant populations decreases and fragmentation increases, ...

Predicting the Probability of Outbreeding Depression

Frankham, Richard; Ballou, Jonathan D.; Eldridge, Mark D. B.; Lacy, Robert C.; Ralls, Katherine; Dudash, Michele R.; Fenster, Charles B. (2011)

Fragmentation of animal and plant populations typically leads to genetic erosion and increased probability of extirpation. Although these effects can usually be reversed by re-establishing gene flow between population ...

Seasonal variation in habitat selection for a Neotropical migratory songbird using high-resolution GPS tracking

Stanley, Calandra Q.; Dudash, Michele R.; Ryder, Thomas B.; Shriver, W. Gregory; Serno, Kimberly; Adalsteinsson, Solny; Marra, Peter P. (2021)

Deciphering how environmental heterogeneity affects population dynamics in migratory species is complicated by the redistribution of individuals in time and space across the annual cycle. Approaches that tackle this problem ...

Species concepts for conservation - Reply to Russello and Amato

Frankham, Richard; Lacy, Robert C.; Ballou, Jonathan D.; Dudash, Michele R.; Eldridge, Mark D. B.; Fenster, Charles B.; Mendelson, Joseph R., III; Porton, Ingrid J.; Ralls, Katherine; Ryder, Oliver A. (2014)

Variable and sexually conflicting selection on Silene stellata floral traits by a putative moth pollinator selective agent

Zhou, Juannan; Reynolds, Richard J.; Zimmer, Elizabeth A.; Dudash, Michele R.; Fenster, Charles B. (2020)

Conflicting selection is an important evolutionary mechanism since it impedes directional evolution and helps to maintain phenotypic variation. It can arise when mutualistic and antagonistic selective agents exert opposing ...

Variable tropical moisture and food availability underlie mixed winter space-use strategies in a migratory songbird

Stanley, Calandra Q.; Dudash, Michele R.; Ryder, Thomas B.; Shriver, W. Gregory; Marra, Peter P. (2021)

Identifying environmental correlates driving space-use strategies can be critical for predicting population dynamics; however, such information can be difficult to attain for small mobile species such as migratory songbirds. ...

Winter habitat quality but not long-distance dispersal influences apparent reproductive success in a migratory bird

Rushing, Clark S.; Marra, Peter P.; Dudash, Michele R. (2016)

Long-distance breeding and natal dispersal play central roles in many ecological and evolutionary processes, including gene flow, population dynamics, range expansion, and individual responses to fluctuating biotic and ...
