The reproductive behavior of Anthidium manicatum (Hymenoptera: Megachilidae) and the significance of size for territorial males
- BiologyBehavioral Ecology and Sociobiology
SummaryMales of the wool-carder bee, Anthidium manicatum, patrol clumps of garden plants. Females of this species visit these plants for pollen, nectar, and pubescence; they also mate there. Females…
Adult size and mate choice in seaweed flies (Coelopa frigida)
The willingness to mate of pairs of seaweed flies was measured using a stock known not to exhibit female mate choice with respect to a chromosomal inversion, and a strong negative correlation was found between female size and the rate of male dismounting.
The Mating Behaviour of the Velvet Ant, Nemka viduata (Hymenoptera: Mutillidae)
- BiologyJournal of Insect Behavior
It is suggested that larger males, which can lift a wider range of female sizes, have a reproductive advantage, as indicated by data obtained on their load-lifting capacity with respect to the size distribution of females.

Immunoecology of species with alternative reproductive tactics and strategies
Immunoecological work on species with ARTS, which is the topic of this review, is particularly interesting because the alternative morphs make it possible to separate the effects of sex, per se, from other factors that in other species are inextricably linked with sex.
Neuroanatomical differentiation associated with alternative reproductive tactics in male arid land bees, Centris pallida and Amegilla dawsoni.
- Biology, PsychologyJournal of comparative physiology. A, Neuroethology, sensory, neural, and behavioral physiology
The results suggest that the divergent behavioral strategies in ART systems can be associated with neuroanatomical differentiation, and this work suggests that conspecific animals pursuing ARTs would exhibit dissimilar brain architecture.
Male strategies and mating behavior in the Neotropical bee Epicharis (Anepicharis) dejeanii (Apidae: Centridini)
- Environmental ScienceJournal of Apicultural Research
The results revealed a greater head width and intertegular distance among males patrolling above the plants, suggesting that the adopted patrol strategy has an association with the body size of males.
The Effect of Kinship on Reproductive Success of Male Nasonia vitripennis (Hymenoptera: Pteromalidae)
The effect of kinship on male reproductive success of the parasitic wasp, Nasonia vitripennis, was measured by comparing the success of pairs of brothers with that of pairs of unrelated males…
ON THE FREQUENCY OF EUSOCIALITY IN SNAPPING SHRIMPS ( DECAPODA : ALPHEIDAE ) , WITH DESCRIPTION OF A SECOND EUSOCIAL SPECIES J .
New collections, and observations made by students of this genus over the last century, suggest that several sponge-dwelling Synalpheus species similarly exhibit overlapping generations and monopolization of reproduction by a few individuals, and thus that these species may also be eusocial according to classical entomological criteria.

Intraspecific Intrusions into Nests of Spawning Longear Sunfish (Pisces: Centrarchidae)
- Environmental Science, Biology
Northern longear sunfish breed in colonies of closely-spaced nests, each defended by a mature male, and the main function of nest intrusion by females is eating eggs; by males it is apparently the fertilization of eggs in another male's nest.
Social Behavior of a South American Leaf Fish, Polycentrus schomburgkii, with an Account of Recurring Pseudofemale Behavior
Remarkably the adults, breeding or nonbreeding, were never seen to eat any of their own young; this is doubtless an adaptation necessary to the perpetuation of such an effective piscivore.
Spacing Patterns in Mobile Animals
- Environmental Science, Biology
This review will examine concepts of spacing patterns in mobile animals from the perspective of their proximate causes, their ecological consequences, and their adaptive significance.
The ecology and evolution of male reproductive behaviour in the bees and wasps
Of special interest in multiple-mating by females, which may be an evolutionary response to the costs of attempting to resist copulation in certain situations, are the ecological and evolutionary bases of these differences that are explored in this paper.

Temporal Leks as a Mating System in a Temperate Zone Dragonfly (Odonata: Anisoptera) I : Plathemis Lydia (Drury)
The behavioral ecology of Plathemis lydia (Drury) (Odonata: Anisoptera) was studied at several ponds in northern New York State and time budgets and analyses of mating behavior of males under various densities are presented and analyzed with reference to a time-energy-maturational-experiential hypothesis for the evolution of the behavior.
Male Dimorphism as a Consequence of Sexual Selection
- BiologyThe American Naturalist
A number of insect species and red deer possess two forms of males differing from each other in the extent of development of devices involved in competition for females, which is a possible mechanism for the maintenance of a genetic polymorphism.
Nesting Behavior of Philanthus albopilosus with Comparisons Between Two Widely Separated Populations
- Environmental Science
Comparison of the 2 widely separated nesting aggregations revealed only one important difference : mean length of the gallery was 18.7 cm in New York (n=7) as compared to 45 cm in Colorado ( n=8) .
