range and frequency of africanized honey bees in california (usa).	africanized honey bees entered california in 1994 but few accounts of their northward expansion or their frequency relative to european honey bees have been published. we used mitochondrial markers and morphometric analyses to determine the prevalence of africanized honeybees in san diego county and their current northward progress in california west of the sierra nevada crest. the northernmost african mitotypes detected were approximately 40 km south of sacramento in california's central valley ...	2015	26361047
complex interactions among biocontrol agents, pollinators, and an invasive weed: a structural equation modeling approach.	herbivores, seed predators, and pollinators can exert strong impacts on their host plants. they can also affect the strength of each other's impact by modifying traits in their shared host, producing super- or sub-additive outcomes. this phenomenon is especially relevant to biological control of invasive plants because most invaders are attacked by multiple agents. unfortunately, complex interactions among agents are rarely studied. we used structural equation modeling (sem) to quantify the effe ...	2012	23387114
