Post-Flowering Photoperiod Sensitivity of Soybean in Pod-Setting Responses

open access: yesBiology
The development of soybean (Glycine max) is regulated by the photoperiod, with genes related to photoperiod sensitivity primarily focused on the flowering time.

Long Days Enhance Recognition Memory and Increase Insulin-like Growth Factor 2 in the Hippocampus [PDF]

open access: yes, 2017
Light improves cognitive function in humans; however, the neurobiological mechanisms underlying positive effects of light remain unclear. One obstacle is that most rodent models have employed lighting conditions that cause cognitive deficits rather than ...

Phytoplankton community dynamics and vertical nutrient fluxes during the winter‐to‐spring transition in a monomictic temperate reservoir

open access: yesLimnology and Oceanography, EarlyView.
Abstract Winter phytoplankton blooms have been documented in several temperate lakes, yet the mechanisms triggering them remain poorly understood. Understanding the ecology of these blooms is key for predicting succession patterns, especially given the impact of climate change on winter conditions.

A novel mechanism explaining the temperature dependence of marine unicellular nitrogen‐fixing cyanobacteria

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract The major marine nitrogen‐fixing cyanobacterium, Crocosphaera watsonii, is restricted to warm tropical and subtropical oceans, while the underlying mechanisms remain unclear. C. watsonii fixes nitrogen (oxygen‐sensitive) and carbon (oxygen‐evolving) during night and day, respectively.

Fast responses, rich insights: Optimizing experimental stream studies using periphyton for comprehensive environmental assessment

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Experimental streams (ESs) are enclosures of fluvial ecosystems designed as flume microcosms to simulate flowing waters and assess environmental disturbances on aquatic communities' structure and function under controlled conditions. This study presents an ES system that combines ecological relevance with reliability in a compact design ...

DIFFERENTIAL EFFECTS OF PHOTOPERIOD ON DEVELOPMENT OF SOLANACEOUS WEED SPECIES [PDF]

open access: yes, 2007
The effect of three photoperiod treatments (10/14, 14/10 and 16/8 h of light and dark intervals) on the growth and development of Solanaceous weeds viz.
