Transgenic pollen harms monarch larvae
TLDR
In a laboratory assay, it is found that larvae of the monarch butterfly, Danaus plexippus, reared on milkweed leaves dusted with pollen from Bt corn, ate less, grew more slowly and suffered higher mortality than larvae rearing on leaves dusting with untransformed corn pollen or on leaves without pollen.

Trade-offs in foraging success and predation risk with spatial position in colonial spiders
TLDR
Spiders in the core of the colony have greater reproductive success, producing more egg sacs with greater hatching frequency, and show a spatial organization predicted by the selfish herd theory.

PREDATORY BEHAVIOR OF SPITTING SPIDERS (ARANEAE : SCYTODIDAE) AND THE EVOLUTION OF PREY WRAPPING I
TLDR
It is argued that prey wrapping at the capture site is an early adaptation of spider radiation into the aerial niche based on the presence of one form or the other in most taxa foraging above ground.

TLDR
It is argued that spiders offer an opportunity to untangle the ecological causes of parental care, which forms the basis of many other animal societies.

Effects of Monarch Larval Host Plant Chemistry and Body Size on Polistes Wasp Predation
Predatory wasps exert a major selective force on lepidopteran larvae (Montllor and Bernays 1993; Raveret Richter 2000). The social paper wasps (Vespidae: Polistes spp.) specialize on lepidopteran…
Dynamics of a Plague Outbreak in Gunnison's Prairie Dog
TLDR
The present report provides detailed population data prior to and during a plague outbreak in the Gunnison's prairie dog.

Ontogenetic shifts within the selfish herd: predation risk and foraging trade-offs change with age in colonial web-building spiders
TLDR
Spatial variation in size-related fitness trade-offs between predation risk and foraging success may explain why colonies are dynamic entities — with individual spiders exhibiting ontogenetic shifts in web location as they grow larger and mature-accounting for the characteristic age (size) structure of Metepeira incrassata colonies.

Effects of habitat quality on growth, age of first reproduction, and dispersal in Gunnison's prairie dogs (Cynomys gunnisoni)
TLDR
In a favorable habitat, Gunnison's prairie dogs were heavier, reached sexual maturity more rapidly, and dispersed at a younger age than in a less favorable habitat.

Age-related sequential web building in the colonial spider Metepeira incrassata (Araneidae): an adaptive spacing strategy
TLDR
Sequential web building appears to be a result of both larger spiders competing to pre-empt space from one another and smaller individuals attempting to reduce conflict during web construction, which helps shape the typical hierarchical size distribution of spiders within the colony.

Do social spiders cooperate in predator defense and foraging without a web?
TLDR
Young spiders benefited directly from maternal defense and prey sharing in the retreat, and older spiders gained no foraging benefit by remaining in their natal colony, suggesting D. cancerides does not share many of the benefits of group living described in other web-building social spiders.
