Emergent group traits, reproduction, and levels of selection

Behavioral and Brain Sciences, 2014
AbstractAll group traits, “emergent” or otherwise, are ultimately dependent on the traits and behaviours of the individuals that constitute the group. Unless a process of “group reproduction” is envisaged, this means that the evolution of group traits can in principle be studied in an individualistic way, by studying the dynamics of the underlying ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Towards an understanding of multimodal traits of female reproduction in chimpanzees

Primates, 2022
AbstractAlthough primates have long been regarded as microsmatic, recent studies indicate that olfaction is an important sensory mode of primate communication, e.g., in the context of reproduction. However, large gaps remain in our understanding of primate olfactory traits, especially in the great apes.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Social and biological determinants of reproductive success in Swedish males and females born 1915–1929 [PDF]

, 2009
Studying biological and social determinants of mortality and fertility provides insight into selective pressures in a population and the possibility of trade-offs between short- and long-term reproductive success.

REPRODUCTIVE PERFORMANCE OF A COMMERCIAL FLOCK OF SUBTROPICAL NEIMI SHEEP IN SAUDI ARABIA [PDF]

Journal of Animal and Poultry Production, 2000
  This study was carried out on a commercial flock of Neimi sheep belonging to Al-Gassim Agric. Company in the mid-region of Saudi Arabia. The work aimed at studying the reproductive performance of this flock under accelerated lambing system. The traits

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Quantitative Genetic Assessment of Female Reproductive Traits in a Domesticated Pacific White Shrimp (Penaeus vannamei) Line in China

, 2020
Seed production can be improved if genetic selection is applied to key reproductive traits when a substantial amount additive genetic variation is present that can be exploited in a selective breeding program.

Kin selection and the evolution of plant reproductive traits [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2016
Competition among developing seeds and sibling rivalry within multiovulated ovaries can be deleterious for both the maternal parent and the siblings. Increased genetic relatedness of seeds within the ovary may foster kin selection and reduce the deleterious consequences of sibling competition.
