Data from: Litterfall and nutrient dynamics shift in tropical forest restoration sites after a decade of recovery

Karen D. Holl, Fernando Casanoves, Rakan A. Zahawi, Danielle Celentano, Diego Delgado & Oscar Lanuza
Multi‐year studies comparing changes in litterfall biomass and nutrient inputs in sites under different restoration practices are lacking. We evaluated litterfall dynamics and nutrient inputs at 5 yr and after a decade of recovery in four treatments (natural regeneration—no planting, plantation—entire area planted, tree islands—planting in patches, and reference forest) at multiple sites in an agricultural landscape in southern Costa Rica. We inter‐planted two native species (Terminalia amazonia and Vochysia guatemalensis) and two naturalized N‐fixing...

Agroecosystem diversification with legumes or non-legumes improves differently soil fertility according to soil type

Plant diversification through crop rotation or agroforestry is a promising way to improve sustainability of agroecosystems. Nonetheless, criteria to select the most suitable plant communities for agroecosystems diversification facing contrasting environmental constraints need to be refined. Here, we compared the impacts of 24 different plant communities on soil fertility across six tropical agroecosystems: either on highly weathered Ferralsols, with strong P limitation, or on partially weathered soils derived from volcanic material, with major N limitation....

Genotype-environment interactions shape leaf functional traits of cacao in agroforests

Marie Sauvadet, Adam Dickinson, Eduardo Somarriba, Wilbert Phillips-Mora, Rolando Cerda, Adam Martin & Marney Isaac
The outbreak of frosty (Moniliophthora roreri) and black pod (Phytophthora palmivora) in Central American cacao agroforests throughout the 1980s, led to the breeding of Theobroma cacao clones resistant to these diseases. However, while clonal disease resistance has been well documented, clonal adaptability to contrasting pedoclimates remains less understood. Plant functional responses to environmental constraints can be assessed by evaluating intraspecific trait variation (ITV), but trait-based approaches have rarely been implemented in genotype assessments. The objective...

Data from: Shade tree traits and microclimate modifications: Implications for pathogen management in biodiverse coffee agroforests

Stephanie Gagliardi, Jacques Avelino, Elias De Melo Virginio Filho & Marney Isaac
Diversified coffee agroforests modify microclimate conditions in comparison to monocultures, impacting the success of significant plant pathogens, such as Hemileia vastatrix, which causes coffee leaf rust (CLR). However, research is often limited to the dichotomous analysis of shaded agroforestry systems or unshaded monocultures, often overlooking the nuanced effect of shade tree trait diversity. Our study aims to determine the cumulative effects of shade tree canopy architectural characteristics and leaf functional traits in biodiverse agroforests on...
