The effect of a 24-hour photoperiod on the survival, growth and swim bladder inflation of pre-flexion yellowfin tuna (Thunnus albacares) larvae [PDF]

open access: yes, 2011
The effects of two different continuous photoperiod regimes on survival, growth and swim bladder inflation of pre-flexion yellowfin tuna (Thunnus albacares) larvae were investigated. Each photoperiod regime was tested twice with a different larval cohort

Implications of holdfast availability and patchiness on juvenile seahorse (Hippocampus reidi) condition and welfare: Simulations in captivity

open access: yesAquaculture, 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

open access: yesAgronomy 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.

Attainment of reproductive competence, phase transition, and quantification of juvenility in mutant genetic screens [PDF]

open access: yes, 2014
Plant development between seedling emergence and flowering is characterized by a series of successive qualitative phases: (1) a post embryonic photoperiodinsensitive phase, during which plants are insensitive to photoperiod; (2) a photoperiod ...

Determination of photoperiod-sensitive phase in chickpea (Cicer arietinum L).

open access: yesFrontiers in Plant Science, 2016
Photoperiod is one of the major environmental factors determining time to flower initiation and first flower appearance in plants. In chickpea, photoperiod sensitivity, expressed as delayed to flower under short days as compared to long days, may change ...

Sensitivity of Immature \u3ci\u3eThyanta Calceata\u3c/i\u3e (Hemiptera: Pentatomidae) to Photoperiod as Reflected by Adult Color and Pubescence [PDF]

open access: yes, 2017
Dimorphism in color and pubescence of adult Thyanta calceata, in response to 8L:16D and 16L:8D photoperiods, resulted from an accumulation of photoperiod effects on two or more immature stages. More immature stages were receptive to 8L:16D than to 16L:8D

Phenological Restriction of the Oryza (v3) Model [PDF]

open access: yesRevista Brasileira de Meteorologia
Photoperiod sensitivity affects the rice development cycle and its flowering. Crop simulation models, such as ORYZA (v3), use equations that depend on two main parameters calibrated by the user: sensitivity to photoperiod and minimum optimal photoperiod.

Effect of photoperiod on body weight gain, and daily energy intake and energy expenditure in Japanese quail (Coturnix c. Japonica) [PDF]

open access: yes, 2000
Effect of photoperiod and food duration on body weight gain, energy intake, energy expenditure, and sexual development were investigated in two strains of Japanese quail (Coturnix c.

Whole‐genomic DNA amplifications from individually isolated sweet sorghum microspores

open access: yesApplications in Plant Sciences, Volume 10, Issue 6, November-December 2022., 2022
Abstract Premise Sorghum is a multi‐use crop, the efficient breeding of which requires the development of new genetic tools. One such tool could be the genetic assessment of free microspores, which are released just after the tetrad stage of pollen development.

Temperature and photoperiod drive spring phenology across all species in a temperate forest community.

open access: yesNew Phytologist, 2018
Accurate predictions of spring plant phenology with climate change are critical for projections of growing seasons, plant communities and a number of ecosystem services, including carbon storage.
