“…Egg production can vary considerably between females of the same population (LEMCKERT & SHINE, 1993;, or may be regulated by climatic conditions (CRUMP, 1974). In a study in the Brazilian Pantanal that measured these variables in females, a positive correlation was found in most of the studied species .…”

ABSTRACT. Reproductive modes and size-fecundity relationships are described for anurans from Picinguaba, a region of Atlantic rainforest on the northern coast of the state of São Paulo, Brazil. We observed 13 reproductive modes, confirming a high diversity of modes in the Atlantic rainforest. This diversity of reproductive modes reflects the successful use of diversified and humid microhabitats by anurans in this biome. We measured the snout-vent length of 715 specimens of 40 species of anurans. The size-fecundity relationship of 12 species was analyzed. Female snout-vent lengths explained between 57% and 81% of clutch size variation. Anurans with aquatic modes laid more eggs than those with terrestrial or arboreal modes. Larger eggs were deposited by species with specialized reproductive modes. KEYWORDS.Reproduction, Anura, clutch size, community. RESUMO.Modos reprodutivos e fecundidade de anfíbios anuros em uma taxocenose na Mata Atlântica, Brasil. Neste estudo são apresentados os modos reprodutivos e as relações de tamanho-fecundidade dos anuros encontrados em Picinguaba, uma região de Mata Atlântica no litoral norte do estado de São Paulo. Foram registrados 13 modos reprodutivos, confirmando a alta diversidade de modos reprodutivos encontrados na Mata Atlântica. A diversidade de modos reprodutivos observados na Mata Atlântica é o resultado do sucesso dos anuros na utilização dos diversos microhábitats úmidos desse bioma. Os comprimentos rostro-cloacais de 715 indivíduos de 40 espécies de anuros foram medidos. Foram consideradas as relações de tamanho-fecundidade para 12 espécies. O tamanho do corpo explicou entre 57% e 81% da variação no tamanho da ninhada. Os modos reprodutivos aquáticos apresentaram maior número de ovos, comparados aos modos reprodutivos terrestres ou arborícolas. As espécies com maior tamanho de ovos foram as que apresentaram modos reprodutivos especializados.

“…The reduction in future reproductive capacity caused by a decrease in survival or growth in exchange for increased current reproductive effort is called 'reproductive cost' (Reznick 1985). Reproductive cost is often measured in terms of lower survival of reproducers (Calow 1973, Tallamy & Denno 1982, Lemckert & Shine 1993, Boyd et al 1995, Jacobsen et al 1995, Luiselli et al 1996 and is called 'survival reproductive cost' (Bell 1980). As indicated by Roff (1992), it is hard to imagine that reproduction does not deplete the resources of an organism, thereby making it more prone to stress-related sources of mortality.…”

We examined the relationship of summer mortality to reproductive events for suspensioncultured mussels h/lytilus edulis L, in the Magdalen Islands. Parameters associated with gametogenesis and spawning were followed along w t h the tuning and intensity of mortality from mid-June to midSeptember 1991. For mussels maintained In a shallow lagoon (the usual mussel culture s~t e ) , summer mortality began in late July as a major spawning event was e n d~n g and as summer temperatures peaked (>20°C). Mussels from this group showed low energetic contents after spawning and during the period of highest mortality, glycogen content decreased rapidly and shell growth ceased. Thus, mussels weakened by a major spawning were at the same time submitted to stressful temperatures. Summer mortalities were observed until the end of the experimental period (mid-September) even though surviving mussels seemed to have improved their condition in late August (when glycogen content, tissue mass and shell length had increased). By mid-September approximately 65 % of the mussels had been lost. In contrast, no summer mortality was observed for mussels from the same stock that were maintained at 16 m depth in the open sea. These mussels were exposed to lower temperatures and spawned less extensively than those in the lagoon. They had no major spawning in late July and were never completely empty of gametes. Our results suggest that suspension-cultured mussels in Magdalen Islands lagoons pay a high reproductive cost in terms of survival when a major spawning is completed during a period of stressful environmental conditions, such as high water temperatures.

“…The pre-breeding period can exert a critical influence on animal survival as upregulation of stress hormones and metabolic rates can leave the reproducing organism more susceptible to predation, starvation, or disease (Jones & Ward 1979;Birchard et al 1984;Angilletta & Sears 2000;Homan et al 2003;Moore & Jessop 2003). Pre-breeding costs may include the loss of body mass or decreased body condition from the reproductive event (Ryser 1989;Lemckert & Shine 1993). These changes can have an important effect on current and future reproductive behaviors and may influence the evolution of an organism's life-cycle history.…”

“…These changes can have an important effect on current and future reproductive behaviors and may influence the evolution of an organism's life-cycle history. For example, the evolution of larger clutch sizes and multiple reproductive events in a single year has resulted in increased body mass loss observed in common eastern frogs (Crinia signifera, Lemckert & Shine 1993). Behavioral response during reproduction can also modify the costs of a breeding event, such as changes in relative clutch mass or body condition (Brodie 1989).…”

Studies examining the association between life-history strategies and behavior can help inform our understanding of the fitness consequences of reproductive behaviors. Breeding migrations are common in numerous taxa and often represent an important reproductive cost. We examined body mass changes of spotted salamanders (Ambystoma maculatum) during their seasonal breeding migrations to determine the influence of breeding behaviors on reproductive costs. We sampled salamanders entering and exiting a 0.92-ha ephemeral wetland in the North Carolina Piedmont using a 400-m drift fence completely encircling the wetland. Traps were checked daily during annual breeding migrations in mid-January to early March of 2013 and 2014. The relationship between body mass changes and explanatory factors including sex, duration of stay at wetland, and distance between site entrance and exit were examined using a set of candidate linear mixed models selected a priori and compared using Akaike's information criterion. Female salamanders lost a greater percentage of body mass during the time in the wetland than males as a result of oviposition. Model selection identified duration of stay as the most important predictor of female body mass change with greater duration of stay associated with lower mass loss. In males, percentage mass loss was most closely associated with site entranceÀexit correspondence with greater distance between entrance and exit sites associated with greater mass loss. These data demonstrate both the importance of wetland entranceÀexit sites and duration of stay at the wetland in determining mass change during spotted salamander reproduction and also that these relationships can differ as a function of sex. Taken together, our findings provide a potential link between behavior, life-history cycles, and costs experienced during reproduction.
