Site fidelity, reproductive behavior and investment in the Brazilian Reticulate Leaf Frog, Pithecopus ayeaye LUTZ, 1966 (Anura: Phyllomedusidae)
(Osterreichische Gesellschaft Herpetologie E V, 2018-08-30)
In this study, the authors describe the reproductive biology of a population of Pithecopus ayeaye LUTZ, 1966, a leaf-frog typical of the Cerrado of southeastern Brazil. Field expeditions were conducted monthly during the ...
Dynamics of energy reserves and the cost of reproduction in female and male fiddler crabs
(Elsevier Gmbh, 2018-02)
The physiological costs of reproduction can be measured as the energy allocated to reproductive activities. In fiddler crabs, females allocate energy to vitellogenesis and brooding, whereas males perform expensive courtship ...
Differential allocation in a gift‑giving spider: males adjust their reproductive investment in response to female condition
(BMC, 2021)
Background: When males are selective, they can either reject low-quality females or adjust their reproductive investment in response to traits that indicate female quality (e.g., body size or condition). According to the ...
Egg-laying site, fecundity and degree of sexual size dimorphism in frogs
(Oxford Univ Press, 2020-11-01)
Female fecundity is an important selective force leading to female-biased sexual size dimorphism (SSD) in frogs. Because anurans exhibit diverse reproductive modes, we investigated whether variation in SSD and fecundity ...
Life history traits of a Neotropical microhylid (dermatonotus muelleri, Boettger 1885) from the arid Chaco, Argentina
(British Herpetological Society, 2016-01)
We explored age-related parameters and growth patterns in a population of Dermatonotus muelleri inhabiting the Arid Chaco, at the southern limit of the species' distribution range using skeletochronology. In addition, we ...
No pain, no gain: Male plasticity in burrow digging according to female rejection in a sand-dwelling wolf spider
(Elsevier Science, 2017-07)
Behavioral plasticity allows individuals to reversibly respond to short-term variations in their ecological and social environment in order to maximize their fitness. Allocosa senex is a burrow-digging spider that inhabits ...
Effect of food addition on the reproductive intensity and timing of both sexes of an intertidal crab
(Inter-Research, 2010-02)
Males and females of most animals time reproduction and synchronize their reproductive activity to maximize lifetime fitness. When food is abundant, however, the 2 sexes may time investments in reproduction differently due ...
Energy allocation to growth and reproduction in a viviparous lizard endemic to the highlands of the Andes, Argentina
(Wiley, 2015-09)
Individuals devote energy intake to growth, maintenance and reproduction, so knowing the way in which they allocate this energy between competing demands is essential to understand their relationship with the environment. ...
Estratégias reprodutivas em serpentes da Tribo Tachymenini (Dipsadidae: Xenodontinae) na região subtropical do Brasil
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade AnimalCentro de Ciências Naturais e Exatas, 2019-11-25)
Thamnodynastes strigatus and Tomodon dorsatus are snake’s species of the monophyletic tribe Tachymenini widely distributed in the subtropical Brazil. Thamnodynastes strigatus is mostly arboreal with a nocturnal activity ...
