Ecological Aspects of Some Mixed-Species Foraging Flocks of Birds
TLDR
Mixed—species flocks of birds composed of chickadees, titmice, woodpeckers, nuthatches, creepers, kinglets, and wood warblers were studied in several habitats in Louisiana, Maryland, and Maine and appear to be an effective adaptation to difficult conditions.
Predatory risk to insects foraging at flowers
TLDR
Interactions between nectar-seeking insects visiting common milkweed and their commonest predator at the inflorescences, the crab spider Misumena vatia (Clerk) (Thomisidae), were recorded.
Crab spiders affect flower visitation by bees
TLDR
This field study is the first field study documenting negative effects of predators on flower visitation rate by pollinator populations and suggests that pollinator response to predation may influence pollinator-plant interactions.
Feeding Behavior and Predator Avoidance in Heterospecific Groups
TLDR
The primary purpose here is to investigate and evaluate the advantages obtained by individuals in heterospecific groupings and, where appropriate, to compare them with single-species groups.
Predator upon a Flower: Life History and Fitness in a Crab Spider
TLDR
This data indicates that foraging strategies used by Xysticus emertoni, a Cohabiting Crab Spider, and Misumena as Part of the Community are likely to have different fitness payoffs than those used by other crustaceans.
Prey capture by the crab spider Misumena calycina (Araneae: Thomisidae)
TLDR
Crab spiders in pasture rose Rosa carolina flowers regularly attacked bumble bees, smaller bees, and syrphid flies that visited these flowers, and did not show a tendency to specialize at any time.
Propagule size, dispersal ability, and seedling performance in Asclepias syriaca
TLDR
The predictions that decreasing size may increase dispersal ability, but also decrease the probability of seedling success, of wind-dispersed seeds are tested and substantial variation in seed morphology both among clones and among pods within clones is found.
American Warblers: An Ecological and Behavioral Perspective
Avian ecologist Morse documents the life cycle of warblers on both their breeding grounds and their migration routes and covers foraging, habitat selection, reproduction, plumage, rare and tropical
Factors driving extreme sexual size dimorphism of a sit-and-wait predator under low density
TLDR
Although direct male–male contests favoured large males, the low densities of adult males and the dispersed, relatively immobile females led to low levels of direct intrasexual contest, scramble competition favoured males that selected flowers attracting many prey, the sites most often occupied by females.
Prey Capture by the Crab Spider Misumena vatia (Clerck) (Thomisidae) on Three Common Native Flowers
TLDR
Spiders hunting on roses invested considerable time finding new flowers each day and also took longer to process prey than did spiders on other flowers, so bumblebees were the most important prey in terms of biomass and small syrphid flieswere the most frequently captured prey.
