1. Consequences of paternal care on pectoral fin allometry in a desert-dwelling fish

Author:

Subject:
Gobiidae; allometry; anaerobic conditions; body size; females; fins; fish; head; males; sexual dimorphism; sexual selection
Abstract:
... Positive static allometry is a scaling relationship where the relative size of traits covaries with adult body size. Traditionally, positive allometry is thought to result from either altered physiological requirements at larger body size or from strongly condition-dependent allocation under sexual selection. Yet, there are no theoretical reasons why positive allometry cannot evolve in fitness-rel ...

2. Dominance, not kinship, determines individual position within the communal roosts of a cooperatively breeding bird

Subject:
birds; body size; evolution; females; flocks; heat; kin selection; kinship; males; sex ratio
Abstract:
... Kin selection has played an important role in the evolution and maintenance of cooperative breeding behaviour in many bird species. However, although relatedness has been shown to affect the investment decisions of helpers in such systems, less is known about the role that kin discrimination plays in other contexts, such as communal roosting. Individuals that roost communally benefit from reduced ...

3. Evolution of mating systems and sexual size dimorphism in North American cyprinids

Behavioral ecology and sociobiology 2013 v.67 no.5 pp. 747-756
ISSN:
0340-5443
Subject:
Cyprinidae; body size; dimorphism; females; fish; males; mating systems; models; phylogeny; spawning; sperm competition; testes
Abstract:
... Mating systems evolve with sexual size dimorphism (SSD) in many animals. Mating systems with males larger than females occur when males compete for female access or guard territories, while mating systems with group mating tend to occur in species where females are the same size or larger than males. In addition to variation in SSD with mating system, sperm competition varies among mating systems ...

4. Experience affects mating behavior, but does not impact parental reproductive allocation in a lizard

Subject:
Anolis; body size; eggs; females; lizards; males; mating behavior; paternal effect; spermatozoa; steroids
Abstract:
... Investment into reproduction is influenced by multiple factors and varies substantially between males and females. Theory predicts that males should adjust their ejaculate size or quality in response to variation in female experience or phenotypic quality. In addition, sperm investment by males may also be influenced by their own status and experience. Although such adjustments of male ejaculate s ...

5. Females prefer males with superior fighting abilities but avoid sexually harassing winners when eavesdropping on male fights

Subject:
Poecilia; body size; females; fish; males; sexual behavior
Abstract:
... Selection imposed by male competition (intrasexual selection) and female choice (intersexual selection) can be con- or discordant. Specifically, females may or may not prefer mating with dominant males, and direct costs of interacting with dominant (and possibly more harassing) males have been suggested to explain avoidance of dominant males. Here, we exemplify that inter- and intrasexual selectio ...

6. Foundress polyphenism and the origins of eusociality in a facultatively eusocial sweat bee, Megalopta genalis (Halictidae)

Megalopta genalis; adulthood; body size; evolution; experimental design; females; insect colonies; insects; life history; nests; phenotype; progeny
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 ...

7. Nitrate affects courting and breathing but not escape performance in adult newts

Abstract:
... The increasing spread of contaminants in the environment affects the behaviour of individuals and can be predicted to modify population characteristics in the long run. It is thus crucial to investigate the effect of contaminants on fitness-related traits. Nitrate is a major pollutant that disrupts oxygen fixation and steroid metabolism and is expected to affect adult behaviour. In water breeding ...

8. Selection for early emergence, longevity and large body size in wingless, sib-mating ant males

Abstract:
... Sexual selection has led to male morphologies and behaviours that either increase male attractiveness or their success in male–male competition. We investigated male traits under selection in the ant Hypoponera opacior, in which wingless males mate with pupal queens inside their natal colony and guard their partners for hours. The lack of female choice and fights among adult males makes this speci ...

9. Weapons or mating signals? Claw shape and mate choice in a fiddler crab

Subject:
body size; claws; courtship; crabs; females; males; sexual selection
Abstract:
... Males often possess traits, such as horns, claws, and tusks, which are used during male–male combat. Studies suggest that selection has fine tuned these weapons to improve their effectiveness and that the shape of these weapons provides cues for males to assess the strength of rivals. Similarly, females might also assess a male’s weaponry to determine his value as a mate. The largest weapon relati ...
