Plants trap pollen to feed predatory arthropods as an indirect resistance against herbivory Plants trap pollen to feed predatory arthropods as an indirect resistance against herbivory
Plants commonly employ indirect resistance to reduce herbivory by provisioning predatory arthropod populations with additional resources. Numerous predatory arthropods consume pollen that is entrapped on dense, wooly trichomes of plants. Over two seasons, we supplemented pollen on the wooly leaves of turkey mullein, Croton setiger, in natural populations to determine if pollen entrapped...

Species-specific responses to wetland mitigation among amphibians in the Greater Yellowstone Ecosystem Species-specific responses to wetland mitigation among amphibians in the Greater Yellowstone Ecosystem
Habitat loss and degradation are leading causes of biodiversity declines, therefore assessing the capacity of created mitigation wetlands to replace habitat for wildlife has become a management priority. We used single season occupancy models to compare the occurrence of larvae of four species of pond‐breeding amphibians in wetlands created for mitigation, wetlands impacted by road...

Carbon chemistry of intact versus chronically drained peatlands in the southeastern USA Carbon chemistry of intact versus chronically drained peatlands in the southeastern USA
The Great Dismal Swamp (GDS) is a large temperate swamp in Virginia/North Carolina with peat soils historically resistant to microbial decomposition. However, this peatland has been subject to ~200 years of disturbance during which extensive drainage, fire suppression, and wide-spread logging have increased decomposition and dramatically decreased the distribution of Atlantic white cedar...

Predicting persistence of Rio Grande Cutthroat Trout populations in an uncertain future Predicting persistence of Rio Grande Cutthroat Trout populations in an uncertain future
The Rio Grande Cutthroat Trout Oncorhynchus clarkii virginalis (RGCT ) occupies just 12% of its ancestral range. As the southernmost subspecies of Cutthroat Trout, we expect a warming climate to bring additional stressors to RGCT populations, such as increased stream temperatures, reduced streamflows, and increased incidence of wildfire. We developed a Bayesian network (BN ) model using...

Interactions between resident risk perceptions and wildfire risk mitigation: Evidence from simultaneous equations modeling Interactions between resident risk perceptions and wildfire risk mitigation: Evidence from simultaneous equations modeling
Fire science emphasizes that mitigation actions on residential property, including structural hardening and maintaining defensible space, can reduce the risk of wildfire at a home. Accordingly, a rich body of social science literature investigates the determinants of wildfire risk mitigation behaviors of residents living in fire-prone areas. Here, we investigate relationships among...

Using scenarios to evaluate vulnerability of grassland communities to climate change in the Southern Great Plains of the United States Using scenarios to evaluate vulnerability of grassland communities to climate change in the Southern Great Plains of the United States
Scenario planning is a useful tool for identifying key vulnerabilities of ecological systems to changing climates, informed by the potential outcomes for a set of divergent, plausible, and relevant climate scenarios. We evaluated potential vulnerabilities of grassland communities to changing climate in the Southern Great Plains (SGP) and the Landscape Conservation Design pilot area (LCD)...

Genetic mark‐recapture analysis of winter faecal pellets allows estimation of population size in Sage Grouse Centrocercus urophasianus Genetic mark‐recapture analysis of winter faecal pellets allows estimation of population size in Sage Grouse Centrocercus urophasianus
The Sage Grouse Centrocercus urophasianus is a species of conservation concern throughout its range in western North America. Since the 1950s, the high count of males at leks has been used as an index for monitoring populations. However, the relationship between this lek‐count index and population size is unclear, and its reliability for assessing population trends has been questioned...

Genomic identity of white oak species in an eastern North American syngameon Genomic identity of white oak species in an eastern North American syngameon
The eastern North American white oaks, a complex of approximately 16 potentially interbreeding species, have become a classic model for studying the genetic nature of species in a syngameon. Genetic work over the past two decades has demonstrated the reality of oak species, but gene flow between sympatric oaks raises the question of whether there are conserved regions of the genome that...

From Manitoba to Texas: A study of the population genetic structure of bur oak (Quercus macrocarpa) From Manitoba to Texas: A study of the population genetic structure of bur oak (Quercus macrocarpa)
In the taxonomic world, the oaks are known as a rambunctious group, notorious for hybridizing. In this report, we present preliminary information to address the question of how much hybridization is occurring between bur oak and white oaks with which it is sympatric, through rangewide sampling of bur oak and five co-occurring species: white oak (Q. alba L.), swamp white oak (Q. bicolor...

Insect herbivores on urban native oak trees Insect herbivores on urban native oak trees
Oak trees host an amazing diversity of insects, many of which specialize on Quercus species. Oak species and genotypes are commonly planted far from where an acorn was produced. Urban plantings, restoration sites, and plantings anticipating climate change each cause this to happen. What evidence exists that provenance of oak plantings affects herbivores such as galls and leaf miners? And...

Responding to risky neighbors: Testing for spatial spillover effects for defensible space in a fire-prone WUI community Responding to risky neighbors: Testing for spatial spillover effects for defensible space in a fire-prone WUI community
Often, factors that determine the risk of an environmental hazard occur at landscape scales, and risk mitigation requires action by multiple private property owners. How property owners respond to risk mitigation on neighboring lands depends on whether mitigation actions are strategic complements or strategic substitutes. We test for these neighbor interactions with a case study on...
