“…Indirect effects of herbivory on litter quality may also impact the productivity of allochthonous aquatic habitats by decreasing the quality of the leaf detritus upon which their food webs are founded, including streams (Irons et al 1991) and tree-holes (Walker et al 1997;Strand et al 1999). In some cases, defoliation can also increase the quality of leaf litter.…”

“…To date no experiments have directly tested competitive outcomes among A. triseriatus , A. albopictus, and A. japonicus with detritus types chosen to represent different land use patterns. The nutritional quality of leaf detritus is highly dependent on the concentrations of nitrogen and carbon-based secondary compounds of the detritus (e.g., phenolics, tannins, and lignin) (Strand et al, 1999; Tuchman et al, 2003). Leaf species decomposition rate increases with nitrogen:carbon (N:C) ratio (Peterson and Cummins, 1974).…”

Arthropod-borne viruses (arboviruses) cause many diseases worldwide and their transmission is likely to change with land use and climate changes. La Crosse virus is historically transmitted by the native mosquito Aedes triseriatus (Say) in the upper Midwestern U.S., but the invasive congeners Aedes albopictus (Skuse) and Aedes japonicus (Theobald), which co-occur with A. triseriatus in water-holding containers, may be important accessory vectors in the Appalachian region where La Crosse encephalitis is an emerging disease. This review focuses on evidence for how climate, land use, and biological invasions may have direct abiotic and indirect community-level impacts on immature developmental stages (eggs and larvae) of Aedes mosquitoes. Because vector-borne diseases usually vary in space and time and are related to the ecology of the vector species, we propose that the ecology of its mosquito vectors, particularly at their immature stages, has played an important role in the emergence of La Crosse encephalitis in the Appalachian region and represents a model for investigating the effects of environmental changes on other vector-borne diseases. We summarize the health effects of La Crosse virus and associated socioeconomic costs that make it the most important native mosquito-borne disease in the U.S. We review of the transmission of La Crosse virus, and present evidence for the impacts of climate, land use, and biological invasions on Aedes mosquito communities. Last, we discuss important questions about the ecology of La Crosse virus mosquito vectors that may improve our understanding of the impacts of environmental changes on La Crosse virus and other arboviruses.

“…There is little formal theory developed to generalize how the dynamics of trait distributions are influenced with growth and reversion, although factors influencing individual growth and reversion rates have been investigated in a range of species. For example, in numerous mosquito species environmental drivers including temperature, genetic effects, intra- and inter-specific competition for food and the presence of predators influence growth rates of larvae and the time taken for transitions between instars (Braks et al 2004; Agnew and Koella 1999; Wallace and Merritt 1999; Strand et al 1999). Any contribution of growth or reversion to a change in the mean of a trait distribution will need to consider the average difference across trait values of survivors before and after selection.…”

Time series of rapid phenotypic change have recently been documented in age-structured populations living in the wild. Researchers are often interested in identifying the processes responsible for such change. Although there is well developed demographic theory to explain time series of population size, equivalent theory does not exist for the mean values of phenotypic traits in structured populations. We derive an equation to exactly decompose change in the mean value of a phenotypic trait into contributions from fluctuations in the demographic structure, and age-specific viability selection, fertility selection, growth and reversion and differences between offspring and parental trait values. We calculate these contributions to fluctuations in mean birth weight in a well characterized population of red deer. Over the > 30 years of the study mean birth weight has not significantly changed. Stasis has occurred because positive viability selection for an increase in birth weight is countered by transmission bias. Our derivation demonstrates that this is only one of many ways in which equilibria in the mean value of a phenotypic trait can be maintained. The age-structured Price equation we derive and apply has the potential to provide considerable insight into the processes generating now frequently reported cases of rapid phenotypic change.
