Silvopastoral systems benefit invertebrate biodiversity on tropical livestock farms in Caquetá, Colombia. [PDF]

Agric For Entomol
Abstract In the Colombian Amazon, there has been long‐term and sustained loss of primary forest threatening biodiversity and climate change mitigation. Silvopastoral practices that integrate trees into livestock production could help address both local economic and wider environmental challenges.

Influencia de la diversidad de especies de plantas en la incidencia de plagas dentro de cultivos en sistemas agroforestales [PDF]

Agronomía Colombiana, 1987
La diversidad de especies ha sido un tema de gran controversia en relación a la estabilidad de los ecosistemas. En esta revisión de literatura se hace énfasis en sus efectos sobre sistemas agroforestales. Cabe anotarse que, aunque se ha discutido acerca de los posibles efectos de la diversidad<br />de especies, son muy pocos los ejemplos que la ...

The long road to a sustainable banana trade

PLANTS, PEOPLE, PLANET, Volume 5, Issue 5, Page 662-671, September 2023., 2023
Bananas are the world's most popular dessert fruit and a staple starch crop for millions in low‐ and middle‐income countries. The banana export trade that supplies North America, Europe, and other wealthy nations has a history fraught with exploitation and conflict.

Plant chemical diversity and its frequency have distinct but complementary effects on insect foraging

Journal of Applied Ecology, Volume 59, Issue 5, Page 1362-1371, May 2022., 2022
Whereas previous work investigates how the amount of chemical diversity in a plant population influences insect ecology, our results indicate that local spatial distribution of diversity is equally important. A key implication of this work is the potential to design cultivar mixtures spatially, at the movement scale of target organisms, to create more ...

Ecological requirements drive the variable responses of wheat pests and natural enemies to the landscape context

Journal of Applied Ecology, Volume 59, Issue 2, Page 444-456, February 2022., 2022
Our findings highlight the need for conservation biological control to go beyond ‘one size fits all’ and consider the specific ecology of the involved organisms, even for a single crop type. Landscapes with high edge density and flowering woody plants may support natural enemies, in particular syrphids, which colonised the fields early in the season ...

What feeds on Quercus ilex L.? A biogeographical approach to studying trophic interactions in a Mediterranean keystone species

Diversity and Distributions, Volume 28, Issue 1, Page 4-24, January 2022., 2022
Abstract Aim Holm oak (Quercus ilex L.) is regarded as a keystone plant species. Trophic interactions may affect the distribution and abundance of phytophagous species, but the number of arthropod species that use holm oak as a food resource and their levels of host specificity are not yet known.

Dynamical System and Nonlinear Regression for Estimate Host-Parasitoid Relationship

Journal of Applied Mathematics, 2010
The complex relationships of a crop with the pest, its natural enemies, and the climate factors exist in all the ecosystems, but the mathematic models has studied only some components to know the relation cause-effect.
