Las estructuras de los árboles [PDF]

open access: yes, 2012
Los árboles se autodiseñan y modifican su forma de tal modo que todas sus células estén sometidas a la misma tensión. Hacerlo así incrementa su seguridad y reduce la posibilidad de caer y morir.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Synergy‐based crop suitability assessment for agrivoltaics: An easy‐to‐use traffic‐light framework for temperate climates

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change and the growing demand for renewable energy are putting increasing pressure on land, as food production and solar power generation often compete for the same areas. In this study, we assessed which temperate‐region crops are best suited for agrivoltaics, a technology combining farming and solar electricity production on the same land. We

Plant species and field site shape root endosphere microbiomes of wild inoculum plants used in traditional cereal‐based fermentation

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Traditional fermented foods worldwide depend on naturally occurring microbes, yet the environmental sources shaping these microbes and their effects on food quality remain poorly understood. We investigated bacteria living inside the roots of wild plants used to produce Munkoyo, a widely consumed nonalcoholic fermented cereal beverage in Zambia, to ...
