The Western Ghats have a high level of anuran endemism.  Although there has been an extensive focus on their taxonomy, the ecology of most species are poorly known.  In this note we describe the reproductive life-history traits and breeding behavior of four species of endemic bush frogs, Pseudophilautus wynaadensis, Raorchestes akroparallagi, Raorchestes glandulosus, and Raorchestes ponmudi (Amphibia: Anura: Rachophoridae) from Wayanad region of Western Ghats.

Reproductive Life History

Pumpkinseed (Lepomis gibbosus) inhabiting two shallow ponds that experienced major winterkills matured 1–2 yr earlier and at a smaller size (difference > 20 mm in length) than conspecifics living in an adjacent, nonwinterkill lake. Pond females were more fecund relative to body weight, and their gonadosomatic index was about double that of lake females. Pond males showed a significant, but less drastic increase in gonadosomatic index over lake males. Winterkills occurred in different years in the two ponds, but in both cases, pumpkinseeds showed significantly lower age and size at maturity following winterkill in comparison with a preceding or subsequent nonwinterkill year. These results are consistent with life history predictions for organisms living in fluctuating environments and indicate that reproductive life history traits are very plastic in pumpkinseeds living in high-risk environments. Advanced maturity following winterkill may be the result of abundant food supply to survivors or release from social factors that prevent maturation of small pumpkinseeds.

SummaryThe effects of habitat fragmentation on the distribution and abundance of birds is a well-researched topic but there is little information published in terms of how habitat fragmentation affects reproductive life history traits. We reviewed the available literature on this subject and found that only 8% of the 1,433 studies dealing with birds in fragmented habitat studied life history traits and only 1.3% provided appropriate data to perform statistics. We found no effect of fragmentation on clutch and brood size patterns. Those patterns did not change when corrected by phylogeny. However, there is a significant heterogeneity among species responses, thus data on large-bodied, ground-nesting, and precocial birds suggest an increasing response in brood size in fragmented habitats. Finally, our review shows that despite birds being the most studied vertebrate group, crucial information such as the effects of habitat fragmentation on life history traits is still scarce and insufficient, especially on species of conservation concern. Indeed, only one out of 15 species reviewed here was threatened. Studies on reproductive, behavioural and life history trait variation are urgently needed in order to advance conservation actions.
