The results show how the presence of an invasive plant and year-to-year variation in plant-pollinator interactions affect the pollination and components of pollinator-mediated selection in native plants.

Jill T. Anderson1,2* and Contemporary climate change is proceeding at an unprecedented rate. The question remains Susana M. Wadgymar3 whether populations adapted to historical conditions can persist under rapid environmental 1 change. We tested whether climate change will disrupt local adaptation an

Climate change is causing species with non-overlapping ranges to come in contact, and a key challenge is to predict the consequences of such species re-shuffling. Experiments on plants have focused largely on novel competitive interactions; other species interactions, such as plant–microbe symbioses

Climate change has had numerous ecological effects, including species range shifts and altered phenology. Altering flowering phenology often affects plant reproduction, but the mechanisms behind these changes are not well-under- stood. To investigate why altering flowering phenology affects plant re

Environmental variation often induces shifts in functional traits, yet we know little about whether plasticity will reduce extinction risks under climate change. As climate change proceeds, phenotypic plasticity could enable species with limited dispersal capacity to persist in situ, and migrating p

Divergent natural selection promotes local adaptation and can lead to reproductive isolation of populations in contrasting environments; however, the genetic basis of local adaptation remains largely unresolved in natural populations. Local adaptation might result from antagonistic pleiotropy, where

Two new endocommensal fungi belonging to the Genistellaceae (Harpellales) were isolated in pure culture from the hindguts of Diptera larvae: Smittium culesitae from the mosquito Culesita impatiens, on a 10% brain‐heart infusion, and S. simulii from the black fly Simulium argus, on a potato dextrose‐
