Subject:
Pardosa; cannibalism; copulation; dimorphism; eggs; fecundity; hunger; males; progeny; virgin females; China
Abstract:
... Sexual cannibalism is hypothesized to have evolved as a way to obtain a high-quality meal, as an extreme mate choice or as a consequence of female aggressive spillover. Here, we examined underlying factors likely to influence sexual cannibalism in the wolf spider Pardosa pseudoannulata (Bösenberg & Strand, 1906) from China, including mating status, female egg-laid status, female hunger level, fema ...

Subject:
Testudo; courtship; females; males; mating systems; paternity; spermatozoa; tortoises
Abstract:
... Sperm storage is widespread in many vertebrate groups, and it is frequently associated with promiscuous mating systems. Chelonian species are one of the most outstanding examples of a promiscuous group capable of long-term sperm storage; specialized structures have evolved within the oviducts of these vertebrates to ensure sperm vitality across reproductive cycles. Thus far, few studies have inves ...

3. Male–male competition and alternative male mating tactics influence female behavior and fertility in Japanese medaka (Oryzias latipes)

ISSN:

Subject:
Oryzias latipes; evolution; females; males; progeny; reproductive behavior; reproductive performance
Abstract:
... Intense male–male competition driven by high male density during mating can result in the evolution of alternative mating tactics that increase male fertilization success. The effects of alternative male mating tactics on females can range from increased fertilization and genetic benefits to decreased fertilization and loss of paternal care. However, the influence of male competitive behavior and ...

Subject:
aggression; females; males
Abstract:
... Communication plays a large role in resource competition, especially for potential mates, and is used by members of the competing sex to assess each other, and simultaneously to evaluate the other sex, which may be advertising its status. To assess the effects of female advertisement on male aggression, males of the decapod Aegla were paired according to body and armament size. Males were left to ...

5. Positive association between social and extra-pair mating in a polygynous songbird, the dickcissel (Spiza americana)

Subject:
breeding; females; males; nesting; nests; paternity; polygyny; progeny; songbirds
Abstract:
... In polygynous species, males appear to gain additional offspring by pairing with multiple females simultaneously. However, this may not be true if some females copulate outside of the social pair bond. Polygynous males could experience lower paternity because of trade-offs among gaining multiple social mates, guarding fertility with these mates, and pursuing extra-pair matings. Alternatively, poly ...

6. Risk-taking behavior in the lesser wax moth: disentangling within- and between-individual variation

Abstract:
... Behaviors that appear to be plastic may well be determined by environmental influences during development. Being able to produce a wide range of variants of one kind of behavior, e.g., a very short and a very long response time to a stimulus under different environmental conditions, can be described as behavioral plasticity. How such behavioral reaction norms develop for individuals is poorly unde ...

Abstract:
... The relationship between signaling and aggression is still unclear despite several decades of research. However, there is a growing interest in studying signals that predict aggressive behavior or fighting ability. The goals of our study were threefold: we investigated the relationship between signaling effort and aggression, the relationship between body condition and aggression, and the effect o ...

Abstract:
... Mixed-species associations are a widespread phenomenon, comprising interacting heterospecific individuals which gain predator, foraging or social benefits. Avian flocks have traditionally been classified as monolithic species units, with species-wide functional roles, such as nuclear, active, passive, or follower. It has also been suggested that flocks are mutualistic interactions, where niches of ...

Abstract:
... Spermatozoa vary greatly in size and shape among species across the animal kingdom. Postcopulatory sexual selection is thought to be the major evolutionary force driving this diversity. In contrast, less is known about how sperm size varies among populations of the same species. Here, we investigate geographic variation in sperm size in barn swallows Hirundo rustica, a socially monogamous passerin ...

Abstract:
... In altricial birds, parental feeding is essential, and its amount may depend on the quality of both parents. A relationship between parental quality and feeding rate is generally attributed to an active adjustment by parents in order to retain good quality mates or ensure high fitness through raising high-quality offspring. However, the behaviour and need of young may also change with parental qua ...

Abstract:
... Handicap models link the evolution of secondary sexual ornaments to physiological costs and thus provide a mechanistic explanation for signal honesty in sexual selection. Two commonly invoked models, the immunocompetence handicap hypothesis (ICHH) and the oxidative stress handicap hypothesis (OSHH), propose suppression of immunocompetence or increase of oxidative stress by testosterone, but empiri ...

Abstract:
... Adolescence is the pivotal transitional phase during which animals become sexually and socially mature and acquire the skills to cope with a variety of environmental challenges on their own. We investigated in a bird species, the zebra finch, how the social environment experienced during this period influences their behaviour in a sexual context. Zebra finches were kept in pairs (male–female or ma ...

Abstract:
... Algae blooms, which can be caused by eutrophication, drastically influence the ecology and behaviour of aquatic organisms. Such impact is often demonstrated in the context of mate choice and predator–prey interactions. In contrast, the influence of increased turbidity on social behaviour is less well understood, although it may have strong influence, at both the level of the individual and the pop ...

Abstract:
... Colorful ornaments in birds are often sexually selected signals of quality, and variation in ornament expression may be mediated by physiological stress through the secretion of corticosterone. However, testing for links between ornamentation and corticosterone often requires sampling live animals, and such physiological measures may not be matched in the time span in which they were sampled (e.g. ...

Abstract:
... The reproductive (queen) and nonreproductive (worker) castes of eusocial insect colonies are a classic example of insect polyphenism. A complementary polyphenism may also exist entirely among females in the reproductive caste. Although less studied, reproductive females may vary in behavior based on size-associated attributes leading to the production of daughter workers. We studied a bee with fle ...

Abstract:
... Food availability does not only refer to the abundance of edible items; accessibility and detectability of food are also essential components of the availability concept. Constraints imposed by a habitat’s physical structure on the accessibility and detectability of food have been seldom treated simultaneously to the abundance of prey at the foraging patch level in observational studies. We design ...

Abstract:
... We compared the natal dispersal behaviour of two mice species under laboratory conditions. Natal dispersal is a movement of an animal from its birthplace to its breeding area. This behaviour is known to be influenced by the mating system. In polygamous species, males are more likely to disperse, while in most of the monogamous species, both sexes disperse. Our subjects, the house mouse (Mus muscul ...

Abstract:
... In lekking species, the allocation of effort into mate attraction signals is not uniform over time, and signalers may expend the greatest effort when potential mates are nearby. Close-range courtship interactions are critical determinants of male fitness and the study of these interactions can therefore answer important questions in sexual selection. In anurans, attention has largely focused on lo ...
