Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

Journal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests

New Phytologist, Volume 249, Issue 4, Page 1992-2009, February 2026.
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Effect of seed circulation systems on the spread and diversity of Xanthomonas phaseoli pv. manihotis infecting cassava crops of the Colombian Caribbean

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 353-364, January 2026.
Cassava is a lifeline for millions of people across the tropics, but its productivity is at risk from a disease called Cassava Bacterial Blight (CBB). In this study, we explore how the everyday practices of farmers exchanging cassava cuttings—a long‐standing tradition—can shape how the disease spreads and evolves in the Colombian Caribbean.

Principales determinantes de la productividad total de los factores en el sector agrario español

Economía Agraria y Recursos Naturales, 2011
In this paper we analyse, as a whole and for the period 1970-95, the outstanding factors that explain the behaviour of total productivity in the Spanish agrarian sector. In the study, two main methods of modeling had been used: those we consider like "traditional" econometric methodology and the methodology of cointegration.
