Ecology and Evolution, Volume 15, Issue 10, October 2025.Blacklegged ticks (Ixodes scapularis), vectors of Lyme disease, have expanded across the Midwestern USA since the 1970s, with at least three genetically structured populations. Fine‐scale genomic and landscape analyses reveal distinct gene flow corridors and barriers, highlighting how environmental connectivity shapes tick range expansion and informing

Indirect effects between deer, mice, and the gypsy moth in a forest community [PDF]
, 2014 White-tailed deer are ecosystem engineers that dramatically alter forest understory vegetation. Consequently, deer can impact many species in a forest through both direct and indirect effects. One species that deer may indirectly affect is the gypsy moth,

International Biological Flora: Tsuga canadensis*
Journal of Ecology, Volume 113, Issue 10, Page 3037-3080, October 2025.Eastern Hemlock is a long‐lived forest tree of eastern North America known for its deep shade and home given to many organisms. Despite surviving large‐scale clearing for agriculture when Europeans arrived, it returned to dominate when the land was abandoned in the mid 1800s.

Quantifying a Dynamic Risk Landscape: Heterogeneous Predator Activity and Implications for Prey Persistence [PDF]
, 2009 Spatial heterogeneity in predation risk can ameliorate impacts on prey populations, particularly for prey of generalists. Spatially heterogeneous risk implies the existence of refugia, and the spatial scale of those refugia and their persistence over ...

Age and Huddling as Determinants of Metabolic Rate in Grasshopper Mice (Onychomys leucogaster) [PDF]
, 1979 The metabolic rates of grasshopper mice (Onychomys leucogaster) were determined every third day from birth to adulthood. Metabolic rates were quantitated by measuring oxygen consumption in an open circuit system.
