Short photoperiod reduces the temperature sensitivity of leaf‐out in saplings of Fagus sylvatica but not in horse chestnut

open access: yesGlobal Change Biology, 2019
Leaf phenology is one of the most reliable bioindicators of ongoing global warming in temperate and boreal zones because it is highly sensitive to temperature variation.

Effects of Continuous Light (LD24:0) Modulate the Expression of Lysozyme, Mucin and Peripheral Blood Cells in Rainbow Trout

open access: yesFishes, 2022
Continuous photoperiod is extensively used in fish farming, to regulate the reproductive cycle, despite evidence suggesting that artificial photoperiods can act as a stressor and impair the immune system.

Multiple-line inference of selection on quantitative traits [PDF]

open access: yesGenetics 201 (1), 305-322 (2015), 2014
Trait differences between species may be attributable to natural selection. However, quantifying the strength of evidence for selection acting on a particular trait is a difficult task. Here we develop a population-genetic test for selection acting on a quantitative trait which is based on multiple-line crosses.

The ecology and quantitative genetics of seed and seedling traits in upland and lowland ecotypes of a perennial grass

open access: yesEvolution Letters, Volume 6, Issue 6, Page 460-473, December 2022., 2022
Abstract Plants have evolved diverse reproductive allocation strategies and seed traits to aid in dispersal, persistence in the seed bank, and establishment. In particular, seed size, dormancy, and early seedling vigor are thought to be key functional traits with important recruitment and fitness consequences across abiotic stress gradients.

Effects of short photoperiod on cashmere growth, hormone concentrations and hair follicle development-related gene expression in cashmere goats

open access: yesJournal of Applied Animal Research, 2023
Shanbei White Cashmere goat is a typical goat species, the growth of cashmere is affected by photoperiod. To further investigate the effects of short photoperiod treatment on cashmere growth, hormone concentrations and hair follicle development-related ...

Uncovering functional brain signature via random matrix theory [PDF]

open access: yesPLoS Computational Biology 15(5): e1006934 (2019), 2017
The brain is organized in a modular way, serving multiple functionalities. This multiplicity requires that both positive (e.g. excitatory, phase-coherent) and negative (e.g. inhibitory, phase-opposing) interactions take place across brain modules. Unfortunately, most methods to detect modules from time series either neglect or convert to positive any ...

Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta‐analysis in insects

open access: yesEvolution Letters, Volume 6, Issue 6, Page 394-411, December 2022., 2022
Abstract Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited ...

Acclimation of circadian rhythms in woodland strawberries (Fragaria vesca L.) to Arctic and mid-latitude photoperiods

open access: yesBMC Plant Biology, 2023
Background Though many abiotic factors are constantly changing, the photoperiod is a predictable factor that enables plants to time many physiological responses.
