Long‐term interactions among individuals are a hallmark of animal societies, but groups rarely remain entirely stable over time. Individuals die or emigrate, or groups become spatially fragmented. Group fragmentation can alter the phenotypic composition of subgroups by separating well‐connected individuals or altering sex ratios, which may alter the execution of collective behaviors. Over 10 days,...
Species interactions are a unifying theme in ecology and evolution. Both fields are currently moving beyond their historical focus on isolated pairwise relationships to understand how ecological communities affect focal interactions. Additional species can modify both the number of interactions and the fitness consequences of each interaction (i.e., selection). Although only selection affects the...
Despite widespread evidence that biological invasion influences both the biotic and abiotic soil environments, the extent to which these two pathways underpin the effects of invasion on plant traits and performance remains unknown. Leveraging a long‐term (14‐year) field experiment, we show that an allelochemical‐producing invader affects plants through biotic mechanisms, altering the soil fungal community...
Strategies of herbaceous species in deciduous forests are often characterized by the timing of life history phases (e.g. emergence, flowering, leaf senescence) relative to overstory tree canopy closure. Although springtime photosynthesis is assumed to account for the majority of their annual carbon budgets, the 12‐month photosynthetic trajectories of forest herbs have not been quantified.
We measured...
