Beetles were captured using speed nets, marked with tungsten needle dot codes on elytra, and released for recapture monitoring to estimate population sizes and dispersal patterns. Elytral condition wa...
Meta-analytical approach to synthesize population-level climate sensitivities across multiple species using structured population models and standardized effect sizes. Incorporates life history traits...
Long-term systematic collection of first sighting and median activity dates for plants, insects, mammals, amphibians and birds in a high-elevation montane ecosystem. Standardized protocols track flowe...
Measurement of water-use efficiency differences between plant sexes using leaf carbon isotope ratios (δ13C) to understand mechanistic basis of sex-specific climate responses.
Size-structured population model that incorporates climate effects on vital rates to project population dynamics and calculate population growth rates. Uses continuous size distributions and matrix pr...
Field census method to quantify pollen receipt patterns in populations of gynodioecious plants with varying sex ratios and floral densities. Involves systematic counting of flowers by sex and measurem...
Wild ant colonies were collected and split into paired fragments, then maintained on controlled diets (carbohydrate vs protein-rich) to test effects of macronutrient balance on behavior. Colony fragme...
Uses centimeter-precision GPS to map exact locations of all individuals in study plots, enabling calculation of population density and neighbor relationships. Plot sizes are adjusted to population cha...
Post-pollination measurement of ovary size changes as a proxy for detecting fertilization events and ovule development. Uses standardized photography and image analysis to quantify ovary dimensions.
Statistical approach using the climwin package to determine optimal phenological windows of climate variables that best predict biological timing by testing multiple window lengths and start dates.
Controlled laboratory assay using prepared stigmas on growth medium to test pollen germination and tube growth across species boundaries. Stigmas are prepared from unopened buds, treated with pure pol...
Calculation of site-specific wetness indices using mean annual precipitation and temperature data to characterize local climate conditions for experimental sites.
Artificial prey made from green modeling clay are deployed on tree branches to estimate bird attack rates over a standardized time period. Attack marks on clay allow identification of predator type an...
Use existing citizen science bird observation data from eBird database to characterize bird abundance and diversity patterns across environmental gradients. Data is filtered for quality and geographic...
Analysis method that reveals demographic and trait mediated processes that buffer population growth using transient life table response experiments.
R script analysis of sex differences in integrated water use efficiency and population operational sex ratios in Valeriana edulis.
