How is female mate choice affected by male competition?
The plethora of studies devoted to the topics of male competition and female mate choice belie the fact that their interaction remains poorly understood. Indeed, on the question of whether competition should help or hinder the choice process, opinions scattered throughout the sexual selection literature seem unnecessarily polarised. We argue, in the light of recent theoretical and empirical adv...
متن کاملIndividual quality and personality: bolder males are less fecund in the hermit crab Pagurus bernhardus.
One explanation for animal personality is that different behavioural types derive from different life-history strategies. Highly productive individuals, with high growth rates and high fecundity, are assumed to live life at a fast pace showing high levels of boldness and risk taking, compared with less productive individuals. Here, we investigate among-individual differences in mean boldness (t...
متن کاملYearly shifts in shell quality for the hermit crab Pagurus longicarpus in coastal Massachusetts
Global warming is expected to result in milder New England winters. In this study we monitored changes in hermit crab shell quality at Nahant, Massachusetts, USA, at intervals during 17 yr between 1997 and 2014 for a single species of hermit crab Pagurus longicarpus occupying the shells of the intertidal periwinkle Littorina littorea. The incidence of hermit crabs occupying damaged shells, shel...
متن کاملEffects of Predation, Competition, and Isolation on the Rate of Shell Selection in the Hermit Crab Pagurus Longicarpus
S 81 increased population size of both species and expansion of the boreal forest, a likely result of global climate change, have caused areas of geographic overlap to occur. The Trumpeter and Tundra Swans are known to be reproductively compatible, as a viable hybrid population exists in Virginia at the Airlie Center’s Swan Research Program (SRP). Further, accounts from local wildlife managers ...
متن کاملConcurrent effects of sperm competition and female quality on male mate choice in the Trinidadian guppy (Poecilia reticulata)
Males are generally expected to be discriminating in their choice of mates when females vary in quality and when under sperm competition from rival males. However, how sperm competition and female quality interact to influence male mating decisions remains poorly understood. Here, we explored the concurrent effects of sperm competition and female body length on male mating decisions in the Trin...
