Calidad de plántula de árboles seleccionados de Leucaena esculenta en sistema agroforestal

Ciencia Ergo Sum, 2021
En condiciones de invernadero se evaluó la calidad de plántulas de progenies selectas de Leucaena esculenta. En este sentido, durante 2017 se estudió el crecimiento de plantas en función de progenies de árboles y edad después de la siembra (DDS ...

Índices de aridez para un sistema agroforestal cafetalero

UVserva, 2022
Con la finalidad de generar información útil para el sector productivo cafetalero, como parte de las actividades del Observatorio de la Cafeticultora Veracruz (OBSERVA-CAFE), se realiza la estimación de distintos índices que permitan conocer las condiciones ambientales en las que se desarrolla el cultivo de café y que ayuden a los productores a toma ...

From the ground up: Patterns and perceptions of herbaceous diversity in organic coffee agroecosystems

Ecological Solutions and Evidence, Volume 3, Issue 3, July–September 2022., 2022
Smallholder farms that transition to organic and biodiverse production are increasingly recognized as strongholds of agrobiodiversity. Yet the emergent herbaceous communities in these organic systems remain understudied, with the functional diversity and management of this stratum relatively unknown.

Cacao flower visitation: Low pollen deposition, low fruit set and dominance of herbivores

Ecological Solutions and Evidence, Volume 3, Issue 2, April–June 2022., 2022
Pollination of native cacao is surprisingly understudied, even though the process is crucial for the global chocolate production. In an understudied peruvian region, we found herbivores as dominant flower visitors, and low pollen deposition.Fruit set was low when flowers were pollinated naturally (2%), but also manually (7%). Our findings highlight the

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.

Reversion of fruit‐dependent inhibition of flowering in Citrus requires sprouting of buds with epigenetically silenced CcMADS19

New Phytologist, Volume 233, Issue 1, Page 526-533, January 2022., 2022
Summary In Citrus, the response to environmental floral inductive signals is inhibited by the presence of developing fruits. The mechanism involves epigenetic activation of the CcMADS19 locus (FLC orthologue), encoding a floral repressor. To understand how this epigenetic regulation is reverted to allow flowering in the following season, we have forced

Contrasting trends in biodiversity of birds and trees during succession following cacao agroforest abandonment

Journal of Applied Ecology, Volume 58, Issue 6, Page 1248-1260, June 2021., 2021
Our research highlights the value of actively cultivated cacao agroforests and secondary forest alongside primary forests as reservoirs of biodiversity. By supporting both biodiversity and livelihoods, traditionally grown shade‐cacao agroforests fall within a people and nature framework.

El ekuaro: un sistema agroforestal tradicional michoacano

Revista Mexicana de Ciencias Agrícolas, 2017
El ekuaro, ecuaro o ekuarhu (ekuaɹu = patio) es un sistema etnoagroforestal tradicional complejo propio del estado de Michoacán y de los P ́urhépechas o Tarascos, que según sus cultivadores puede formar parte de la vivienda, ya que se interrelaciona con el hogar, la troje, la crianza y explotación de ganado, mayor y menor, la ...

Servicio ecosistémico de carbono almacenado en cafetales bajo sombra en sistema agroforestal

Revista Mexicana de Ciencias Agrícolas, 2022
Los sistemas agroforestales (SAF’s) de café tienen un alto potencial en la captura de carbono (C) gracias a la gran diversidad de especies leñosas usadas como sombra. El objetivo del presente estudio fue evaluar el potencial de captura de carbono en la biomasa vegetal aérea, mantillo y la materia edáfica en diferentes profundidades de suelo en cinco ...
