Sonja Wild, Gustavo Alarcón-Nieto & @lucymaplin show that young #GreatTits, which have limited #ParentalCare, learn to solve a foraging #puzzle socially, but rather than parents, siblings & non-parental adults are preferred role models @PLOSBiology plos.io/46JZn6n
#ParentalCare
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.

A trophic #egg is an egg whose function is not #reproduction but #nutrition; in essence, the trophic egg serves as food for offspring hatched from viable eggs. In most species that produce them, a trophic egg is usually an #unfertilised egg. The production of trophic eggs has been observed in a highly diverse range of species, including #fish, #amphibians, #spiders and #insects. The function is not limited to any particular level of #parentalCare.
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!

"A key difference between the small and large species may have been #ParentalCare. This may have released large #pterosaurs from growth and size constraints. An extended maturation period where parents protected their young and fed them may have allowed a larger body size"
How #ParentalCare affects the Evolution of #GeneticVariation by Rahia Mashoodh. Not sure if it’s parentale care per se or strong #Selection pressures related to the novel environmental conditions caused by preventing parental care that are responsible for the changes in genetic variation, but the approach and the questions were very neat! #Behaviour2023
Flugpate Marko brachte die 3 ersten IT-Spenden zum Parental Child Care-Projekt nach Mbale in Uganda. Vielen Dank.
Team Leader Wepukhulu Jeremiah bedankt sich auch im Namen der Kinder für diese tolle Lernmöglichkeit mit 2 Laptops und einen Tablet. Aber 15 Geräte fehlen noch und müssen vor Ort gebracht werden...

"#Caecilians are an elusive type of #amphibian that primarily live #underground and look like a cross between a worm and a snake. One of the few things that is known about caecilians is their unique method for feeding their young."

"Small pterosaurs were born with comparatively strong, large wings, which meant they could leave the nest swiftly, while the cumbersome baby large pterosaurs required parental protection from #predators"
Today, Laura Pasquier (not on Mastodon) presented her PhD project on the effects of #pesticides on #parentalCare in #earwigs in front our our institute
It was a great talk followed by a great discussion!
Looking forwards to talk more about the first (exciting) results! 🤯
@PaleoParaDive #Postdoc #Introduction Karina Vanadzina joined our team in Oktober. #She has a wide #experience with #phylogenetic #comparative methods and #macroecological analyses which she will use to investigate how #parasites and their #hosts respond to changing #Climate. She recently completed her #PhD @ St Andrews, UK, where she worked on the #evolution of #parentalcare in #vertebrates.
By contrast with other species, human survive postreproductive period. Our delayed #senescence could be explained by our social structures in which grandparents remain active to provision offspring. #science #physiology #parentalcare #menopause
