Dormancy, Diapause, and the Role of the Circadian System in Insect Photoperiodism.
Annual Review of Entomology, 2020 Whole-animal experiments devised to investigate possible association between photoperiodic time measurement and the circadian system (Bünning's hypothesis) are compared with more recent molecular investigations of circadian clock genes.

Timing of puberty by photoperiod [PDF]
Reproduction Nutrition Développement, 1988 Photoperiod cues play an important role in the timing of puberty in the female lamb. Removal and replacement of photoperiod cues by denervation of the pineal gland and timed melatonin infusions, respectively, indicate that the pathway for transmission of photoperiod information develops well before puberty.

Circadian clock mechanism driving mammalian photoperiodism
Nature Communications, 2020 The annual photoperiod cycle provides the critical environmental cue synchronizing rhythms of life in seasonal habitats. In 1936, Bünning proposed a circadian-based coincidence timer for photoperiodic synchronization in plants. Formal studies support the

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 470-483, December 2022., 2022 In Yellowstone Lake, Wyoming, lake trout carcasses are used to suppress invasive lake trout embryos in an effort to conserve native Yellowstone cutthroat trout. Using a field experiment, we determined that carcass treatment had limited, non‐target effects on benthic invertebrates.

Photoperiodism and Diapause in Insects [PDF]
Nature, 1949 DURING the past five years, work has been in progress at Rothamsted on rearing in the laboratory a number of plant-feeding insects. One of the aims has been to maintain supplies of insects in large numbers throughout the year. This has necessitated a study of the factors affecting diapause, the quiescent phase in which most plant-feeding insect species

RNAlater facilitates remote sampling of aquaculture Atlantic salmon liver for proteomic analysis
Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 578-586, December 2022., 2022 Graphical Abstract Proteomes of similar sizes were obtained in samples preserved by snap‐freezing or RNAlater. Proteins involved in transcriptional and translational machinery were affected in RNAlater stored samples. Abundance of published markers for heat and oxidative stress was not affected by snap‐freezing or RNAlater.

Backpack electrofishing does not contribute to external signs of gas bubble trauma in sculpins
Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 572-577, December 2022., 2022 Abstract We exposed prickly sculpin Cottus asper and reticulate sculpin Cottus perplexus to electroshock and sham treatments in a controlled laboratory setting to determine if backpack electrofishing contributed to or exacerbated external signs of gas bubble trauma (GBT) in fish exposed to elevated total dissolved gas (TDG) levels. Fish were exposed to

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 552-561, December 2022., 2022 Abstract Seahorses (Genus Hippocampus; Family Syngnathidae) are iconic fish characterised by tails with prehensile capabilities, which develop after the transition from planktonic to benthonic lifestyle. As a result, seahorses remain attached to vegetal structures or other elements most of the time, both in the wild and under rearing conditions. In the

Downy mildew resistance and genetic variability in a wild rocket germplasm collection
Agronomy Journal, Volume 114, Issue 6, Page 3083-3095, November/December 2022., 2022 Abstract One hundred accessions of a “core collection” of Diplotaxis tenuifolia (L.) DC. and Eruca spp. were screened at seedling stage for resistance to downy mildew. Accessions tested at the seedling stage were assigned to 0–6 interaction phenotypes.
