"B" = breeding sites determined by the presence of eggs, tadpoles-larvae, chorusing adults, or pairs in amplexus
. "Y" = sites where amphibians were observed but there was no evidence of breeding activity.
Some species of frog need to go into amplexus
for weeks or even months, but it isn't known how long it lasts for the Sehuencas.
occurring between amphibians of different orders (Hobel, 2005a; Simovic et al., 2014), families (Sodre et al., 2014; Clause et al., 2015; Bell & Scheinberg, 2016; Reilly et al., 2016), genera (Streicher et al., 2010; Kindermann, 2015; Marchant et al., 2015; Loc-Barragan et al., 2016), and species (Hobel, 2005b; Ceron & Zocche, 2016; Schalk, 2016) that overlap spatially and temporally has been documented previously, even if one of those involved is dead (Waterstrat et al., 2008; Muller, 2016), or both are males (Costa-Campos et al., 2016).
For each individual anuran found, we recorded the species, location, activity (calling, amplexus
, resting), and microhabitat according to type of substrate (sand, leaf-litter, rock and water) or plant life-form (tree, grass, bromeliads, agaves, herbs).
Trade-off between male reproduction (amplexus
) and growth in the amphipod Gammarus lawrecnianus.
Emerson (1991) suggested that total length of forelimbs may not be most appropriate measure for sexual selection in frogs, and emphasized functional aspect of their segments (humerus and radioulna) in amplexus
. The increase of these elements allows stronger hold of males on females during amplexus
and resistance of takeover by competing males (Howard & Kluge 1985).
Aquatic eggs are fertilized by multiple males not engaged in amplexus
in a stream-breeding frog.
(14) For Cola's embrace of Petrarch as teacher, see Cola di Rienzo a Francesc Petrarca, July 27, 1347, Epistolario XV (37-8): "[I]n gratissimo exhortamine vestro, per exempla laudabilia bonorum veterum, per eccitationes ad virtutum amplexus
, nos sumus et fuimus plurimum recreati" ("In your very gratifying letter of exhortation, you have summoned the praiseworthy examples of the heroes of old to spur us on to emulate their virtuous deeds, whereby our spirits are and have been thoroughly revived").
Et nobis idem Alcimedon duo pocula fecit et molli circum est ansas amplexus
acantho Orpheaque in medio posuit siluasque sequentis; necdum illis labra admoui, sed condita seruo.
uidebanturque ei dies pauci prae amoris magnitudine: quo ad speciosae rachelis castos hanelabat amplexus
" (MOMBRITIUS, 1910, p.
It's called amplexus
. He jumps on her for a cuddle and they externally fertilise.
Quick climb onto my back and cry wreck it wreck it like a frog in the grip of ecstatic amplexus
