MINIATURE AMPHIBIAN DISCOVERED IN PERU, CARRIES YOUNG ON ITS BACK

A new tiny frog, Gastrotheca mittaliiti, found in Peru's Amazon carries its young in a back pouch, a rare way for frogs to reproduce.

Scientists found a new tiny frog in Peru that is only 3 cm long and carries its babies on its back in a special pouch. This is different from most frogs that lay eggs in water.

Laubach et al. discover that physiological constraints may contribute to the early-life disadvantage of slow growth, especially in the context of lower parental care, a result that aligns with the differential acquisition hypothesis.

Atkins Coleman et al. investigate effects of parental care on offspring fitness and the extent to which adult offspring resemble their genetic parents in parental investment, revealing complex selective pressures favoring offspring sex-ratio adjustment.

It has repeatedly been shown that the evolution of parental care is related to large eggs and consequently often to small clutches. Kudo et al. conduct the first study clarifying the evolution of parental care linked with small eggs in invertebrates.

The dilemma between keeping the eggs warm and surviving starvation when you are an incubating bird in the Arctic. Far from being measurement artefacts, extended recess is a sensible strategy under harsh environmental and poor body conditions. Congratulation to Léa Etchart for this new paper from her PhD project.

David F. Westneat used correlational and experimental data to test three causal hypotheses for individuality in parental care. The complexity of personality and plasticity brings new ideas for the biological links between them. Read now ahead of print!
