A sexual network approach to sperm competition in a species with alternative mating tactics
(International Society for Behavioral EcologyCary, 2014-09)
Alternative mating tactics are common among species exhibiting resource defense polygyny. While large territorial males aggressively defend harems, small sneaker males generally invade these harems to mate furtively. The ...
Do Feeding Resources Induce the Adoption of Resource Defence Polygyny in a Lekking Butterfly?

Occurrence of male morphotypes in the freshwater prawn Macrobrachium acanthurus Wiegmann, 1836 (Decapoda, Palaemonidae)
(2021-01-01)
This study tested the hypothesis of the existence of male morphotypes in Macrobrachium acanthurus, a species of recognized economic potential, with an extensive geographic distribution. The collections occurred on eight ...
Reproductive flexibility in South American camelids: First records of alternative mating tactics in wild guanacos (Lama guanicoe)Flexibilidad reproductiva en camélidos sudamericanos: Primeros registros de tácticas de apareamiento alternativas en guanacos silvestres (Lama guanicoe)
(Consejo Nacional de Investigaciones Científicas y Técnicas. Instituto Argentino de Investigación de Las Zonas Áridas. Unidad de Zoología y Ecología Animal, 2020-06)
Intraspecific variation in mating behavior has been documented in diverse taxa, including ungulates. Here, we report and describe for the first time the existence of alternative mating tactics in a wild guanaco (Lama ...
Male size-dependent dominance for burrow holding in the semiterrestrial crab Neohelice granulata: multiple tactics used by intermediate-sized males
(Springer, 2016-09-08)
Dominance and the establishment of social hierarchies are frequently related to size: the larger individuals gain greater reproductive success, while the smaller ones display alternative mating strategies. We studied the ...
Weak polygyny in California sea lions and the potential for alternative mating tactics
(PLoS ONE, 2012)
Female aggregation and male territoriality are considered to be hallmarks of polygynous mating systems. The development of genetic parentage assignment has called into question the accuracy of behavioral traits in predicting ...
Do individuals in better condition survive for longer? Field survival estimates according to male alternative reproductive tactics and sex
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
There is a gap in terms of the supposed survival differences recorded in the field according to individual condition. This is partly due to our inability to assess survival in the wild. Here we applied modern statistical ...
Male dimorphism of a neotropical arachnid: harem size, sneaker opportunities, and gonadal investment
(OXFORD UNIV PRESS INCCARY, 2012)
Serracutisoma proximum is a harvestman with alternative male morphs. Large males use sexually dimorphic second legs in fights for the possession of territories on the vegetation, where females oviposit. Small males have ...
