And Behavior

Although women engage in both physical and nonphysical aggression, little is known about how aggression type influences perceptions of their morphology, personality, and social behavior. Evolutionary theory predicts that women avoid physical aggression due to risk of injury, which could compromise reproductive success. Engaging in physical aggression might therefore decrease women’s perceived mate value. However, physical aggression could be advantageous for some women, such as those who are larger in size and less vulnerable to injury. This presents the possibility that physically aggressive women might be perceived as larger and not necessarily lower in mate value. These hypotheses have not been tested. Across three studies, I used narratives to test the effect of aggression type (physical, verbal, indirect, nonaggressive) on perceptions of women’s height, weight, masculinity, attractiveness, and social status. In Studies 1 and 2, participants perceived a physically aggressive woman to be both larger and more masculine than nonphysically aggressive women. In Study 3, participants perceived both a physically aggressive woman and a nonaggressive woman to be larger than an indirectly aggressive woman; the effect of aggression type on perceptions of a hypothetical man’s height was not significant. I also found some evidence that aggression type influenced perceptions of attractiveness and social status, but these were small and inconsistent effects that warrant further study. Taken together, the results suggest that physical and indirect aggressive behavior may be associated with certain morphological and behavioral profiles in women.

And Behavior

In a multitude of animals with internal fertilization, including insects and mammals, sperm are stored within a female's reproductive tract after mating. Defects in the process of sperm storage drastically reduce reproductive success. In Drosophila males, “Acp” seminal proteins alter female postmating physiology and behavior, and are necessary for several aspects of sperm storage. For example, Acps cause a series of conformational changes in the mated female's reproductive tract that occur during and immediately after mating. These conformational changes have been hypothesized to aid both in the movement of sperm within the female and in the subsequent storage of those sperm. We used RNAi to systematically knock down several Acps involved in sperm storage to determine whether they played a role in the mating-induced uterine conformational changes. Mates of males lacking the glycoprotein Acp36DE, which is needed for the accumulation of sperm in the storage organs, fail to complete the full sequence of the conformational changes. Our results show that uterine conformational changes are important for proper accumulation of sperm in storage and identify a seminal protein that mediates these changes. Four Acps included in this study, previously shown to affect sperm release from storage (CG9997, CG1656, CG1652, and CG17575), are not necessary for uterine conformational changes to occur. Rather, consistent with their role in later steps of sperm storage, we show here that their presence can affect the outcome of sperm competition situations.

Early stage and adult characters (morphology and behavior) indicated that the riodinid Apodemia paucipuncta had been erroneously placed in the genus Apodemia (Incertae Sedis, previously in tribe Emesini). To infer the systematic position of paucipuncta, we performed a cladistic analysis using 72 male morphology characters for 36 species placed in six genera. Our results show that (1) Apodemia paucipuncta is the sister species of Adelotypa eudocia and together they constitute a new genus in the tribe Nymphidiini, Hallonympha, new genus; (2) species of Adelotypa closely related to Catocyclotis and Nymphidium also constitute a new genus, Harveyope, new genus; and (3) sampled species of the Nymphidiini genera Adelotypa and Calospila do not form monophyletic groups, indicating that these genera are in need of revision. This study furthers our understanding of character definition and homology of the male valva and transtilla within the Nymphidiini, and provides a baseline for future work on riodinid systematics.

Local Habitat

Female survival, number of young weaned, and offspring survival were documented for 130 individual Peromyscus maniculatus in the Kananaskis Valley, southwestern Alberta. Reproductive success was highly variable, ranging from 0 to 19 young per female at weaning and from 0 to 12 young per female at the end of the breeding season. Breeding success was not related to body size of the female prior to breeding, and the commitment to reproductive processes had no negative effects on female survival or the survival of the offspring. Most of the variation in reproductive success was attributable to female survival. Females that survived the entire breeding season weaned, on average, twice as many young as females that did not survive the breeding season. We suggest that physiological and behavior compensation and local habitat effects mask potential costs of reproduction during the breeding season. We speculate that any negative effects of high reproductive success may be evident during the nonbreeding season, or prior to breeding in the spring.

We gathered data from 208 American Redstart (Setophaga ruticilla) nests from 1979 to 1985 in southwestern New Brunswick to examine patterns in nest-tree features. Most nests were located in either speckled alder (30.7%) or white birch (22.1%). Nest-site features (nest height, relative nest height, nest access distance) were relatively consistent for those nests located in some tree taxa (alder) but considerable intrataxa variability (cedar, white birch) and several significant intertaxa differences were observed. These differences may reflect each species' branching geometry. Our data were not entirely consistent with existing models of nest-height distribution.
