Multi-objective optimization shapes ecological variation [PDF]

open access: yes, 2013
Ecological systems contain a huge amount of quantitative variation between and within species and locations, which makes it difficult to obtain unambiguous verification of theoretical predictions.

Locus specific engineering of tandem DNA repeats in the genome of Saccharomyces cerevisiae using CRISPR/Cas9 and overlapping oligonucleotides

open access: yesScientific Reports, 2018
DNA repeats constitute a large part of genomes of multicellular eucaryotes. For a longtime considered as junk DNA, their role in genome organization and tuning of gene expression is being increasingly documented.

Life Before Fermi - Back to the Solar System [PDF]

open access: yesarXiv, 2018
The existence of intelligent, interstellar traveling and colonising life is a key assumption behind the Fermi Paradox. Until recently, detecting signs of life elsewhere has been so technically challenging as to seem almost impossible. However, new observational insights and other developments mean that signs of life elsewhere might realistically be ...

Environmental conditions during early life accelerate the rate of senescence in a short-lived passerine bird [PDF]

open access: yes, 2015
Environmental conditions experienced in early life may shape subsequent phenotypic traits including life history. We investigated how predation risk caused by domestic cats (Felis silvestris catus) and local breeding density affected patterns of ...

Life-history variation and age at maturity in Eurasian Perch (Perca fluviatilis L.) [PDF]

open access: yes, 2003
This thesis deals with life-history variation in perch, with special focus on age at maturity. We conducted field studies to uncover the variation within short geographic distances and a literature review to study variation on a large geographic scale in

Human Life History Strategies

open access: yesEvolutionary Psychology, 2017
Human life history (LH) strategies are theoretically regulated by developmental exposure to environmental cues that ancestrally predicted LH-relevant world states (e.g., risk of morbidity–mortality).

Combining Envelope Methodology and Aster Models for Variance Reduction in Life History Analyses [PDF]

open access: yesarXiv, 2017
Precise estimation of expected Darwinian fitness, the expected lifetime number of offspring of organism, is a central component of life history analysis. The aster model serves as a defensible statistical model for distributions of Darwinian fitness.
