Abstract Objective Populations of Lake Whitefish Coregonus clupeaformis have supported commercial fisheries in the Laurentian Great Lakes for centuries, and while recent basinwide trends are down, population resident to waters Green Bay has experienced an increasing trend since at least early 2000s, partly attributable reestablished river-spawning populations productivity. The result is amplified harvest parts lower bay interest quotas. central goal this study was provide managers with a...
Despite obvious impacts of nonnative species in many ecosystems, the long-term outcome competition between native and exotic often remains unclear. Demographic models can resolve provide insight into conditions favoring exclusion vs. coexistence. California grasslands are one most heavily invaded ecosystems North America. Although perennial bunchgrasses thought to be restricted a fraction their original abundance, eventual with invasive European annual grasses at local scale (competitive...
Isolated trees in savannas worldwide are known to modify their local environment and interact directly with neighboring plants. Less is about how related tree species differ impacts on surrounding communities, the effects of vary between years, composition might change following loss tree. To address these knowledge gaps, we explored questions: How do savanna influence herbaceous plants? Is consistent across different years? does this death tree? We surveyed environmental attributes living...
Abstract In many regions, the climate is changing faster during winter than other seasons, and a loss of snow cover combined with increased temperature variability can expose overwintering organisms to harmful conditions. Understanding how species respond these changes critical developmental times, such as seed germination, helps us assess ecological implications change. To address this concern, we measured breaking dormancy cold tolerance temperate grassland in lab field. lab, ran...
Abstract Scattered trees in grass‐dominated ecosystems often act as islands of fertility with important influences on community structure. Despite the potential for these to be useful restoring degraded rangelands, they can also serve sites establishment fast growing non‐native species. In California oak savannas, native perennial grasses are rare beneath isolated oaks and annual dominate. To understand mechanisms generating this pattern, restoration under oaks, we asked: what effects tree...
To better understand agricultural nutrient losses, we evaluated relationships between management (e.g., manure and tillage), soil health measurements, resulting edge-of-field (EOF) surface water quality. This work was conducted before or early into conservation implementation at 14 Great Lakes Restoration Initiative EOF sites spanning Wisconsin, Michigan, Indiana, Ohio, New York. Analyses of site characteristics (hydroclimate, management, catchment properties) along with 3 yr measurements...
