Allometry of reproduction in broad-snouted caiman (Caiman latirostris)

Abstract: In the present study regression equations are established between broad-snouted caiman (Caiman latirostris) captive reproductive females snout-vent length (SVL) and body mass (BM) and the following clutch characteristics: egg mass, egg "length" (maximal diameter), egg "width" (minimal diameter), hatchling BM, hatchling SVL, clutch size (number of eggs), clutch mass and relative clutch mass (clutch mass/ female BM). Female body-length presented a positive correlation with egg mass, egg length, egg width, hatchl… Show more

“…The Broad-snouted Caiman (Caiman latirostris) is a medium-sized crocodilian reaching a maximum total length (TL) of 3.5 m, although in some areas within its range, individuals >2 m are rare in the wild (Verdade et al, 2010).…”

“…The Broad-snouted Caiman has a wide latitudinal distribution in South America (between 5°S and 32°S; Filogonio et al, 2010;Verdade et al, 2010), with the southernmost distribution occurring in Santa Fe province, Argentina (31°S; Simoncini et al, 2009), where populations have been under management by "Proyecto Yacaré" since 1990 (Larriera, 1990). Proyecto Yacaré in Argentina (Larriera et al, 2008), was undertaken to achieve sustainable use of caimans in wetlands in Northern Santa Fe Province.…”

“…Apesar disso, não foram encontradas relações entre o tamanho corpóreo da fêmea e a massa relativa da ninhada (P>0,05), que seria traduzida como a energia investida na reprodução. Isso indica que não existe uma diferença no investimento energético entre fêmeas de diferentes classes de tamanho (ou idades), ao contrário do que foi observado por para P. expansa e em algumas espécies de crocodilianos (THORBJARNARSON; HERNÁNDEZ, 1993;LARRIERA et al, 2004;VERDADE, 2001).…”

“…Já Thorbjarnarson (1996), King (2000) e Verdade (2001), fazendo um paralelo, correlacionam parâmetros de fêmeas (comprimento e massa total, largura entre as narinas), de ovos (comprimento e massa dos ovos), da ninhada (tamanho, massa, comprimento e largura) para explicar reprodução em crocodilianos. Congdon et al (1999) dizem que, na ausência de cuidados parentais, uma das táticas adotadas por tartarugas é aumentar sua fecundidade e também aumentar a probabilidade de sobrevivência dos filhotes pelo aumento do tamanho do corpo do filhote (WILLIAM, 1966;FRETWELL, 1974;BROCKELMAN, 1975;PACKARD;PACKARD, 1988).…”
