Tracking the Pulse of the Dunes: Seasonal Metabolic Responses of Liolaemus arambarensis to Climatic Variability

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Seasonal environmental fluctuations profoundly influence ectothermic vertebrates, regulating their physiology, metabolism, and life cycles. This study investigated the metabolic and morphometric seasonal dynamics of the subtropical sand lizard Liolaemus arambarensis, an endangered species endemic to the coastal dunes of southern Brazil.

Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends

open access: yesInternational Journal of Climatology, EarlyView.
Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

Dormancy in reproductive vegetative buds in creeping perennials dominating the agricultural weed flora in Scandinavia [PDF]

open access: yes, 2013
Dormancy, which is the inability to initiate normal growth under otherwise favourable conditions, is an adaptation to escape sprouting prior to seasonal cold temperatures and/or drought in areas where winters are harsh or summers dry.

Growing Degree‐Day Trends Associated With ‘False Springs’ in the Continental United States

open access: yesInternational Journal of Climatology, EarlyView.
Earlier spring warming has increased growing degree‐day (GDD) accumulation prior to the last freeze at some US locations (red circles = stat. sig. increases). However, after accounting for spatial autocorrelation using a false discovery rate approach, few trends remain significant, indicating no coherent continental‐scale increase in false spring risk.

Effect of different photoperiod regimes in combination with natural and artificial light on nutrient uptake in bok choy (Brassica rapa L.) using an internet of things-based hydroponics system

open access: yesJournal of Agricultural Engineering
In the present study, we analyzed the effect of using a hydroponic system inside a greenhouse and different photoperiod regimes with artificial light on the nutrient uptake of bok choy. Light duration treatment consisting of both sunlight and artificial

Iron Fertilization of Soybean Genotypes Differing in Iron Use Efficiency Under Alkaline Conditions: Implications for Yield and Seed Nutritional Quality

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Soybean, a nutritionally important protein‐ and oil‐rich legume, is highly sensitive to iron (Fe) deficiency under alkaline conditions, where reduced Fe availability limits growth, yield, and seed quality. Effective biofortification therefore requires increasing seed Fe while reducing phytate that restricts Fe bioavailability.

Extended photoperiod improves growth and nutritional quality of pak choi under constant daily light integral

open access: yesFrontiers in Plant Science
Introduction and AimThe duration of light exposure each day, termed the photoperiod, is a crucial environmental cue that influence several aspects of plant physiology, including growth, development, and metabolic activity.

Reproductive biology of carpenter seabream (Argyrozona argyrozona) (Pisces: Sparidae) in a marine protected area [PDF]

open access: yes, 2005
The carpenter seabream (Argyrozona argyrozona) is an endemic South African sparid that comprises an important part of the handline fishery. A three-year study (1998−2000) into its reproductive biology within the Tsitsikamma National Park revealed that ...

Insect‐resistant soybean genotypes accumulate rutin and its O‐methylated derivative narcissin, a more potent flavonol targeting Anticarsia gemmatalis digestive and detoxification enzymes and reducing larval survival

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Soybean underpins Brazil's agricultural, yet its sustainability is threatened by lepidopteran pests such as Anticarsia gemmatalis. Although insect‐resistant cultivars have long been associated with the constitutive accumulation of quercetin‐derived flavonols, the biochemical mechanisms underlying this resistance remain poorly ...
