Some Effects of Photoperiod and Cold Storage on Oviposition of the Cereal Leaf Beetle Oulema Melanopus (Coleptera: Chrysomelidae) [PDF]

open access: yes, 2017
An expanded program of research on the cereal leaf beetle, Oulema melanopus (L.), in various north-central states has made it necessary to develop methods of rearing all stages of the beetle for laboratory use. Because the insect survives diapause in the

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.

A functional nexus between photoperiod acclimation, torpor expression and somatic fatty acid composition in a heterothermic mammal. [PDF]

open access: yesPLoS ONE, 2013
The seasonal changes in thermal physiology and torpor expression of many heterothermic mammals are controlled by photoperiod. As function at low body temperatures during torpor requires changes of tissue lipid composition, we tested for the first time ...

Why does low intensity, long-day lighting promote growth in Petunia, Impatiens, and tomato? [PDF]

open access: yes, 2008
Numerous reports demonstrate that low intensity, long-day (LD) lighting treatments can promote growth. However, there are conflicting suggestions as to the mechanisms involved.

Effects of Photoperiod and Temperature on Energy Budgets and Endocrine Hormones Concentrations in Tupaia belangeri [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2014
Environmental cues play important roles in the regulation of an animal’s physiology and behavior. In the present study, we performed a factorial experiment (temperature/photoperiod) in which Tupaia belangeri was acclimated to different photoperiods (long

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

open access: yesAdvanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

Plants Distinguish Different Photoperiods to Independently Regulate Post-Flowering Vegetative Growth and Reproductive Growth

open access: yesPlants
The post-flowering stage is critical for plant yield and seed quality. This can be influenced by the photoperiod; however, the underlying mechanisms are not clear.

Flowering of kiwifruit (Actinidia deliciosa) is reduced by long photoperiods [PDF]

open access: yes, 2007
Mature kiwifruit (Actinidia deliciosa ‘Hayward’) vines grown under standard orchard management were exposed to 16-h photoperiods from the longest day in summer until after leaf fall in autumn.

Root‐Stimulated Movements in Mimosa Pudica for Biohybrid Robotic Systems

open access: yesAdvanced Robotics Research, EarlyView.
This study demonstrates that thermal and electrical stimulation of Mimosa pudica root induces movement of the petiole and pinnules without direct stimulation of the aerial organs, thereby enabling a plant‐based robotic gripper and providing a foundation for the development of intelligent and sustainable systems.
