Biological identifications through DNA barcodes
Although much biological research depends upon species diagnoses, taxonomic expertise is collapsing. We are convinced that the sole prospect for a sustainable identification capability lies in theExpand

Biological identifications of mayflies (Ephemeroptera) using DNA barcodes
Abstract We tested the efficacy of DNA barcodes in identifying mayfly species primarily from the northeastern United States and central Canada. We sequenced a 630-base-pair segment of theExpand

Predator‐‐Induced Life History Changes: Antipredator Behavior Costs or Facultative Life History Shifts?
We used laboratory experiments to show that the nonlethal presence of pumpkinseed sunfish (Lepomis gibbosus) results in smaller size at emergence, decreased growth and development rates, and lowerExpand

DNA barcodes for insect pest identification: a test case with tussock moths (Lepidoptera: Lymantriidae)
Reliable and rapid identification of exotic pest species is critical to biosecurity. However, identification of morphologically indistinct specimens, such as immature life stages, that are frequent...

Spill-over of pest control and pollination services into arable crops
In order to make agriculture more sustainable it is important to enhance the natural processes supporting crop production, including pollination and pest control. The distance over which theseExpand

Inter‐and intracontinental sexual compatibility in Sclerospora graminicola
Oospore collections of Sclerospora graminicola, obtained from diverse locations in West Africa and India, were used to infect susceptible pearl millet plants. Asexual spores, collected from fiveExpand

Microhabitat selection by larval Chironomus tentans (Diptera: Chironomidae): effects of predators, food, cover and light
SUMMARY 1. As part of a study designed to estimate the developmental costs of antipredator behaviour of larval chironomids, we used laboratory experiments to study effects of food and factors thatExpand

PREDATOR-INDUCED LIFE HISTORY CHANGES:
We used laboratory experiments to show that the nonlethal presence of pumpkinseed sunfish (Lepomis gibbosus) results in smaller size at emergence, decreased growth and development rates, and lowerExpand

The non‐lethal effects of predators and the influence of food availability on life history of adult Chironomus tentans (Diptera: Chironomidae)
SUMMARY 1. We used a laboratory experiment to determine effects of a predator (other than straightforward prey consumption) and food availability, during the larval stage, on adult size, age atExpand
