Herbivore cues and plant damage-associated compounds jointly alter seed germination and seedling herbivory Open
While plant defense against herbivory is primarily thought to occur following attack, there is also evidence that plants can detect and respond to pre-attack cues. These cues include chemicals released from damaged conspecifics and kairomo…

Urbanization, Not Invasive Shrubs, Alters Tree Seed Fate by Modifying Rodent Activity Open
Changes in the global environment are widespread and may have unappreciated effects on the activity of animals and the strength of animal‐mediated interactions. For example, urbanization and the spread of invasive species are aspects of gl…

The influence of human presence and footprint on animal space use in US national parks Open
Given the importance of protected areas for biodiversity, the growth of visitation to many areas has raised concerns about the effects of humans on wildlife. In 2020, the COVID-19 pandemic led to temporary closure of national parks in the …

Deer Vigilance and Movement Behavior Are Affected by Edge Density and Connectivity Open
Animal behavior is an important component of individual, population, and community responses to anthropogenic habitat alteration. For example, antipredator behavior (e.g., vigilance) and animal movement behavior may both be important behav…

Promoting acorn survival using capsaicin seed coatings is strengthened by the removal of invasive shrubs Open
Promoting regeneration of native trees, like Quercus spp., is a priority for land managers given the ecological and economic importance of oak woodlands. Although direct seeding may promote recruitment of Quercus spp., the effectiveness of…

Congeneric Rodents Differ in Immune Gene Expression: Implications for Host Competence for Tick‐Borne Pathogens Open
Mice in the genus Peromyscus are abundant and geographically widespread in North America, serving as reservoirs for zoonotic pathogens, including Borrelia burgdorferi ( B. burgdorferi ), the causative agent of Lyme disease, transmitted by …

Freeze–thaw events differently affect survival of seeds of two native and two invasive woody species Open
Current and projected changes in climatic conditions (e.g., increased freeze–thaw events) may have detrimental effects on the survival of seeds that are essential for plant regeneration in forest ecosystems. We conducted a factorial experi…

Individual variation underlies large‐scale patterns: Host conditions and behavior affect parasitism Open
Identifying the factors that affect host–parasite interactions is essential for understanding the ecology and dynamics of vector‐borne diseases and may be an important component of predicting human disease risk. Characteristics of hosts th…

Invasive shrubs amplify seasonal granivory, revealing optimal windows for seed survival following invasive shrub removal Open
Invasive shrubs dramatically reduce the biodiversity of native plants, making invaded areas important targets of conservation and restoration. Adding seeds of native plant species, in addition to the removal of invasive plants, is a potent…
View article: Herbivore kairomones affect germination speed, seedling growth, and herbivory
Herbivore kairomones affect germination speed, seedling growth, and herbivory Open
Seeds and seedlings are particularly vulnerable to herbivory. Unlike mature plants, which can wait until herbivory is experienced to induce defense, seeds and seedlings face mortality if they wait. Slug mucus functions as a kairomone, a no…

Climate drives geographic variation in individual<i>Peromyscus leucopus</i>immunity against zoonotic disease Open
Geographic variation in host immunity could have major influences on disease dynamics, including zoonotic forms that affect humans. Such variation in immunity could be driven by variation in climate, either directly or, more likely, indire…

Invasive shrubs differentially alter autumnal activity for three common small‐mammal species Open
Seasonal variation in animal activity influences fitness and the intensity of ecological interactions (e.g., competition, predation), yet aspects of global change in the Anthropocene may catalyze shifts in seasonal activity. Invasive plant…

Seeds and seedlings are particularly vulnerable to herbivory. Unlike mature plants, which can wait until herbivory is detected to induce defense, seeds and seedlings face mortality if they wait. Slug mucus functions as a kairomone, a non-a…
View article: White-tailed deer responses to acoustic predator cues are contingent upon past land use and contemporary fire regime
White-tailed deer responses to acoustic predator cues are contingent upon past land use and contemporary fire regime Open
Prey can assess the immediate risk of predation by detecting cues of predator presence, and it is expected that prey should invest in costly antipredator behaviors when a cue of predator presence is detected. Features of the habitat in whi…

Long-term, large-scale experiment reveals the effects of seed limitation, climate, and anthropogenic disturbance on restoration of plant communities in a biodiversity hotspot Open
Ecological restoration is essential for maintaining biodiversity in the face of dynamic, global changes in climate, human land use, and disturbance regimes. Effective restoration requires understanding bottlenecks in plant community recove…

Sandy seeds: Armour or invisibility cloak? Mucilage‐bound sand physically protects seeds from rodents and invertebrates Open
Seeds represent a stage of a plant's life cycle that is extremely vulnerable to predation, which unlike most vegetative herbivory, is fatal to the individual. As such, understanding the distribution and abundance of plants may rely on unde…

Exome sequencing of deer mice on two California Channel Islands identifies potential adaptation to strongly contrasting ecological conditions Open
Understanding the forces that drive genotypic and phenotypic change in wild populations is a central goal of evolutionary biology. We examined exome variation in populations of deer mice from two of the California Channel Islands: Peromysc…

The dominant role of animal social status in vertebrate seed dispersal Open
Seed dispersal directly affects plant establishment, gene flow, and fitness. As a result, understanding patterns in seed dispersal is fundamental to understanding plant ecology and evolution, as well as addressing challenges of extinction …

Litter removal reduces seed predation in restored prairies during times when seed predation would otherwise be high Open
Understanding patterns of seed predation in tallgrass prairie restorations is vital because seed additions are often used by managers to increase diversity and promote native species. However, the success of seed additions depends on the e…

Large ecosystem-scale effects of restoration fail to mitigate impacts of land-use legacies in longleaf pine savannas Open
Significance The restoration of degraded ecosystems is a global priority, yet successful restoration is challenged by the lingering degrading impacts of human land-use activities, like agriculture. Using a large-scale experiment within the…
