Allosuckling in domestic hair sheep: a rare behavior associated with multiple births and male lambs

open access: yesFrontiers in Ethology
Allonursing or allosuckling is a rare but an intriguing evolutionary behavior reported in several species including mammals. Despite the energy cost of lactation, females occasionally allow alien offspring to suckle, suggesting potential adaptative ...

Implantation‐On‐Chip: An AI‐Based Platform for Monitoring the Embryo Trophoblast–Endometrial Stroma Cross Talk With Xenobiotics Interference

open access: yesAdvanced Intelligent Systems, EarlyView.
We present a novel AI‐integrated implantation‐on‐chip platform that enables mimicking and monitoring the maternal–fetal interactions at the early phases of human embryo implantation with high spatiotemporal resolution. The complexity of the trophoblast invasion process was addressed by conducting the analysis at global (rate of invasion) and local ...

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Vivências da maternidade na adolescência precoce

open access: yesRevista de Saúde Pública
OBJETIVO: Embora pouco estudada no Brasil, a maternidade na adolescência de 10 a 14 anos é considerada não desejada e problema de saúde pública. A maior parte dos estudos tem o conceitual crono-biomédico como marco teórico, e poucos abordam esta questão ...

Intertemporal Substitution in Maternal Labor Supply: Evidence using State School Entrance Age Laws [PDF]

open access: yes
In this paper, I propose a new framework to study the intertemporal labor supply hypothesis. I use an exogenous source of variation in maternal net earning opportunities, generated through school entrance age of children, to study intertemporal labor ...

Two decades of resurrection studies: What have we learned about contemporary evolution of plant species?

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Global climate change has altered the eco‐evolutionary trajectories of plant species, leading to observed shifts in phenotypes, such as earlier flowering. However, disentangling the contributions of plasticity and adaptation to trait changes remains challenging.
