Selection for domestication favored taxa characterized by fast growth and tolerance of high intraspecific density

PLANTS, PEOPLE, PLANET, Volume 7, Issue 3, Page 850-860, May 2025.
To understand why certain plants have been domesticated into crops, we need to recognize that the environmental conditions plants experience in wild populations are totally different from those of agricultural fields. In this study, we investigated whether the characteristics that promote growth and survival in these different environments may have ...

Assessing Closed Hydroponic Subsystems for Batavia Lettuce Growth Under Different Planting Densities

World Water Policy, Volume 11, Issue 2, Page 427-438, May 2025.
ABSTRACT Hydroponic systems have the potential to be sustainable and alternative methods for food production that confer advantages of high production and better control of growth. However, only a few studies have focused on leafy vegetable growth in different subsystems and environmental variables.

An open‐source LED lamp for use with the LI‐6800 photosynthesis system

Applications in Plant Sciences, Volume 13, Issue 1, January-February 2025.
Abstract Premise Controlling light flux density during carbon dioxide assimilation measurements is essential in photosynthesis research. Commercial lamps are expensive and are based on monochromatic light‐emitting diodes (LEDs), which deviate significantly in their spectral distribution compared to sunlight.

Reintroduction affects demographic rates but not their interannual correlations in an endangered shrub

Journal of Applied Ecology, Volume 61, Issue 12, Page 3040-3052, December 2024.
Our study shows that stressful conditions may trigger individual‐level trade‐offs in resource allocation and population‐level compensation among demographic rates. Demographic shifts arising from reintroductions in different environmental conditions may be considered by managers as a potential mechanism of resilience against environmental change ...
