Hypoxia-Limited Survival, Respiration, and Mate-Guarding Behavior in the Amphipod Gammarus Pseudolimnaeus Bousfield
… and effects of hypoxia on precopulatory mate-guarding behavior of the amphipod, Gammarus pseudolimnaeus, were tested to determine if seasonal hypoxia in Lake Taneycomo could be a limiting factor for amphipods in the lake. Currently, the Army Corps of Engineers uses oxygenation procedures …

An Assessment of the Effects of Sexual Selection and the Social Environment on Mating Behaviors in Two Tiger Beetle Species (Coleoptera: cicindelidae)
Mate guarding is a sexually selected behavior performed by males of many species that results due to sperm competition. Facultative mating behaviors are predicted to occur in these taxa when changes in the social environment alter the benefits for guarding males. I used field observations and lab …

Effects of supplemental food on the behavior, aggression, and paternity status of male Indigo Buntings (Passerina cyanea)
… the possible effect of food availability on male mate guarding behavior. Additionally, previous results from food supplementation studies are mixed. My objectives were to determine how food supplementation might influence the breeding behavior of male Indigo Buntings (Passerina cyanea). I …

The Social System of the Round-Eared Sengi(Macroscelides proboscideus)
… I determined the social organisation and male mate guarding in wild animals in the Goegap Nature Reserve, South Africa. Data were collected over three successive breeding seasons and one non-breeding season by radio-tracking and trapping over a period of 2.5 years. Additionally, extra-pair …

The Evolution of Orthopteran Mating Systems and the Reproductive Ecology of New Zealand Cave Wētā
… many model species for the study of acoustic mate calling, nuptial provisioning, intrasexual combat, the economics of reproduction that contribute to sexual conflict, and countless other topics in the realm of reproductive ecology. The current research delves into the diversity of mating …

Reproductive Decisions in American Robins (Turdus Migratorius): Relationships Among Paternity Allocation, Parental Care, Plumage Variation, and Mate Choice
… by examining how these interactions affect mate-guarding opportunity, extra-pair paternity (EPP), parental care, and mate choice in the American robin, Turdus migratorius, a socially monogamous, multi-brooded songbird. Reproductive success in American robins was strongly influenced by the …

Clarifying the role of attention on Own Gender Bias in face recognition
… with an evolutionary viewpoint, where partner guarding and mating purposes variables were hypothesized to act as motivation. It was argued that if Own Gender Bias is subsumed by motivation (as suggested by CIM) then females who routinely inspect other females for mate guarding purposes would …

Living apart together
… lemurs (Phaner furcifer), a small nocturnal primate from Madagascar living in dispersed pairs. First, I characterise their social organization, focusing on behavioural mechanisms of cohesion between pair partners. Second, through application of van Schaik's ecological model, I investigate …

Molecular regulation of vasopressin receptor among (mostly) monogamous prairie voles
… EPF males have large home-ranges and frequently mate with other females, but do so at the cost of being cuckolded. IPF males however, form small exclusive home-ranges, rarely intrude and are better at mate-guarding. These behavioral differences are predicted by abundance of the vasopressin …

Sexual selection and biological diversification: Patterns and processes
… I term this the bodyguard hypothesis of female mate choice. I present data illustrating the effectiveness of protective males in reducing the probability of aggression from other males and suggest the importance of protective mating alliances in the evolution of a diversity of animal mating …

The evolution of mating systems in black scavenger flies (Diptera: Sepsidae)
… of this research support the pre-copulatory mate guarding hypothesis for the adaptive significance of escorting behaviour, and they suggest that conspecific populations vary significantly in the degree or nature of sexual selection acting both on morphology and behaviour of males. …

Flight Vocalizations and Displays of Adult Chimney Swifts (Chaetura Pelagica): Description and Function
… pair bonding, pair synchronization, and possible mate-guarding. This study also supports the physiological synchronization and pair bond maintenance hypothesis of V-ing (a raised wing display) because the display occurred more frequently during close chases involving two birds. Interactive group …

Factors influencing parasite-related supression of mating behavior in the isopod caecidotea intermedius
… male mating responsiveness (e.g. willingness to mate) is reversible (from no mating attempts to positive mating attempts). However, little is known about the potential ultimate and proximate mechanisms underlying these relationships. Additionally, the potential role of host counteradaptation …

The effect of economic scarcity on women’s direct aggression toward ovulating women
When people feel like their relationship may be threatened by a rival, they engage in competition with the rival (Buss,1988). Previous work has found that women are more jealous of and guard their partners more from women who are in the fertile phase of their ovulatory cycle than from women who are …

Strategies of Sexual Reproduction in Aphids
Die durchschnittliche Dauer der zweiten Kopulation von Uroleucon cirsii (L.) ist sowohl für Männchen als auch für Weibchen kürzer als die der ersten. Dies legt die Vermutung nahe, dass die männlichen Blattläusen zur Verfügung stehende Menge Sperma limitiert ist. Des weiteren wird Ejakulat von …
