Abstract Reproductive success is often related to parental quality, a parameter expressed through various traits, such as site selection, mate selection and energetic investment in the eggs or progeny. Owing to the complex interactions between environmental and parental characteristics occurring at various stages of the reproductive event, it is often complicated to tease apart the relative contributions of these different factors to reproductive success. Study systems where these complex interactions are simplified (e.g. absence of parental care) can help us to understand how metrics of parental quality (e.g. gamete and egg quality) influence reproductive success. Using such a study system in a common garden experiment, we investigated the relationships between clutch hatching success (a proxy of clutch quality) and offspring quality in an amphibian species lacking post-oviposition parental care. We found a relationship between clutch quality and embryonic development duration and hatchling phenotype. We found that hatchling telomere length was linked to hatching success. These results suggest that clutch quality is linked to early life traits in larval amphibians and that deciphering the influence of parental traits on the patterns we detected is a promising avenue of research.

Extended Parental Care

The genusAbispaincludes Australia's largest wasps, potters with distinctive mud nests weighing up to 0.5 kg. During 31 days near Katherine, NT, Australia, we observed 8 activeA. ephippium(Fabricius) nests and dissected 16. Nesting is lengthy and asynchronous; female generations often overlap. Females display long-term parental care through truncated progressive provisioning, removing debris, repairing damage, and attacking potential invaders. Males patrol water-gathering spots, and visit and associate with active nests, mating there and in flight. Females actively guard nests, but challenged nest-attending males simply retreat. The distinctive funnel-shaped entrance helps females defend nests physically but probably not chemically; dismantled for cell closure material, it is built anew for each cell. Nests contain up to 8 cells; construction and provisioning total about 7 days per cell. The only parasite wasStilbum cyanurumForster. Thievery and nest usurpation byPseudabispa paragioides(Meade-Waldo) were discovered.

Didelphis Aurita

Abstract: Choosing the nest site to raise a litter has consequences on female fitness in mammalian species with no male participation in the parental care. We accidentally video recorded a coati's nest appropriation by a female opossum Didelphis aurita, at Parque Ecológico do Tietê, State of São Paulo, Brazil. For 29 days, from December 22, 2011, to January 19th, 2012, the activity of the female was video recorded 24h/day with a camera trap installed close to the nest. At her first appearance, she had infants in her pouch. After taking leaves to the nest twice on the first night, she kept a routine of going out after sunset and returning to the nest before dawn, carrying leaves on the tail on seven occasions. During the last days of recording, infants were seen attached to the female's body. Another episode of a female opossum with infants using a nest previously constructed by a coati was registered in 2013. To our knowledge, this is the first continuous description of the daily activity of opossums during the nesting phase.

Egg Laying

AbstractEggs of the Urodele Euproctus montanus were discovered in a torrent in the forest of Zonza (Corsica). Our observations lead to the conclusion that egg-laying in this species takes place in agrouped manner both in space in time, and that the females stay close to their eggs during the embryonic development. Both these characters distinguish this species within its genus and suggest the possible existence of parental care.

Fluorescent Studies

Embryonic development is a dynamic event and is best studied in live animals in real time. Much of our knowledge of the early events of embryogenesis, however, comes from immunofluourescent analysis of fixed embryos. While these studies provide an enormous amount of information about the organization of different structures during development, they can give only a static glimpse of a very dynamic event. More recently real-time fluorescent studies of living embryos have become much more routine and have given new insights to how different structures and organelles (chromosomes, centrosomes, cytoskeleton, etc.) are coordinately regulated. This is in large part due to the development of commercially available fluorescent probes, GFP technology, and newly developed sensitive fluorescent microscopes. For example, live confocal fluorescent analysis proved essential in determining the primary defect in mutations that disrupt early nuclear divisions in Drosophila melanogaster. For organisms in which GPF transgenics is not available, fluorescent probes that label DNA, microtubules, and actin are available for microinjection.
