The spread of invasive species and infectious disease as drivers of ecosystem change
Invasive species, disease vectors, and pathogens affect biodiversity, ecosystem function and services, and human health. Climate change, land use, and transport vectors interact in complex ways to

TLDR
Grasshoppers may speed up nitrogen cycling by changing the abundance and decomposition rate of plant litter, which increases total plant abundance, and whether grasshoppers enhance plant abundance depends on how much they consume.
Summer Diet Optimization by Beaver
TLDR
Foraging data collected for beaver at Isle Royale National Park, Michigan, during the summer of 1973 provided basic natural history information pertaining to diet, food preferences, rates of consumption and activity cycle consistent with a linear programming model of herbivore optimal foraging.
The Great Salt Lake Ecosystem (Utah, USA): long term data and a structural equation approach
TLDR
There is little interaction of brine fly larvae with brine shrimp through competition, or with corixids or grebes through predation, indicating that the lake's two food webs are weakly connected.

TLDR
This work empirically test the hypothesis of herbivore diet selectivity and the pattern of resource use that it produces in the field and experimentally and the results may have general applicability to other types of foragers, with general implications for how biodiversity is influenced.
Dynamics of two Montana grasshopper populations: relationships among weather, food abundance and intraspecific competition
TLDR
The observed annual changes in food abundance were correlated with the annual variation in weather, which indicated that the long established relationship between grasshopper densities and weather conditions does not imply population limitation by density-independent processes.
SUSCEPTIBILITY TO PREDATION FOR DIFFERENT GRASSHOPPERS: AN EXPERIMENTAL STUDY'
TLDR
Predation rates indicate that predators are only able to impact seriously (reduce life expectancy below the suitable abiotic period for existence) the largest Oedo- podinae, making predation of little consequence for most grasshopper populations in this environment.
Herbivore Optimal Foraging: A Comparative Test of Three Models

TLDR
The results presented here contradict Owen-Smith and Novellie's (1982) claim that linear programming is a special case and the contingency model is a representation of herbivore diet choice and the model of food energy content weighted by abundance might not be expected to work a priori, because it is not an optimal foraging model.
Time budgets of grassland herbivores: body size similarities
TLDR
The observed feeding time differences for species composing a common trophic level in a single environment may help to explain their diet choice because feeding time constrains the variety of foods an herbivore can select.
