The Evolutionary Consequences of Selection at the Haploid Gametic Stage [PDF]

open access: yesThe American Naturalist, 2018
As an immediate consequence of sexual reproduction, biphasic life cycles with alternating diploid and haploid phases are a common characteristic of sexually reproducing eukaryotes. Much of our focus in evolutionary biology has been directed toward dynamics in diploid or haploid populations, but we rarely consider selection occurring during both phases ...

Genomic consequences and selection efficacy in sympatric sexual versus asexual kelps

open access: yesFrontiers in Marine Science, 2022
Genetic diversity can influence resilience and adaptative capacity of organisms to environmental change. Genetic diversity within populations is largely structured by reproduction, with the prevalence of asexual versus sexual reproduction often ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

On the Evolutionary Consequences of Disruptive Selection [PDF]

open access: yesBolletino di zoologia, 1973
Abstract Allo scopo di analizzare le conseguenze evolutive della selezione divergente sono state considerate quattro linee di Drosophila melanogaster ottenute sia mediante selezione direttiva (HH, LL) sia mediante selezione divergente (HL, LH) per la lunghezza dell'ala.

The Combined Effect of Obesity and Contraceptive Use on Pulmonary Embolism in Adolescent Females Residing in the United States

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Combined oral contraceptive (COC) use in obese adult women dramatically increases the relative risk of developing a pulmonary embolism (PE). The risk of a PE in obese adolescent females taking contraceptives is currently unknown. The purpose of this investigation was to determine the effect of body mass index (BMI) and contraceptive

Immune response from a resource allocation perspective

open access: yesFrontiers in Genetics, 2012
The immune system is a life history trait that can be expected to trade off against other life history traits. Whether or not a trait is considered to be a life history trait has consequences for the expectation on how it responds to natural selection ...

Consequences de la sélection de variables sur l'interprétation des résultats en régression linéaire multiple [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2005
Consequences of variable selection on the interpretation of the results in multiple linear regression. A priori or a posteriori variable selection is a common practise in multiple linear regression.

Nutritional-Landscape Models Link Habitat Use to Condition of Mule Deer (Odocoileus hemionus)

open access: yesFrontiers in Ecology and Evolution, 2020
In heterogeneous landscapes, large herbivores employ plastic behavioral strategies to buffer themselves against negative effects of environmental variation on fitness.

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.
