Geographic, taxonomic and metric gaps in biodiversity research limit evidence‐based conservation in agricultural landscapes: An umbrella review por Bonfanti, Jonathan, Langridge, Joseph, Avadí, A., Casajus, N., Chaudhary, A., Damour, G., Estrada-Carmona, Natalia, Jones, Sarah K., Makowski, D., Mitchell, M., Seppelt, R., Beillouin, Damien

“…Evidence predominantly stems from averaged abundance data, revealing substantial gaps in studies on functional and phylogenetic diversity. Our findings highlight the need to analyse combinations of multiple practices to accurately reflect real‐world farming contexts, and covering a wider range of taxa, biodiversity metrics and spatial levels, to enable evidence‐based conservation strategies in agriculture. …”

Morphological and molecular characterization of common bean landraces and cultivars from the Caribbean por Durán, L.A., Blair, Matthew W., Giraldo Zapata, Martha C., Macchiavelli, Raúl E., Prophete, E, Nin, JC, Beaver, James S.

“…To test this hypothesis, we analyzed the morphological characteristics, phenological traits, phaseolin status, and random amplified polymorphic DNA (RAPD) banding patterns of 54 red mottled or large-seeded bean landraces and cultivars from the Caribbean (16 from the Dominican Republic, 14 from Haiti, 1 from Jamaica and 23 from Puerto Rico) compared with 11 Andean bean lines from other regions. To estimate phylogenetic relationships among the lines, distances were calculated and dendrograms constructed for morphological and/or phenological and molecular characteristics by the complete clustering method. …”

Survey, molecular detection and characterization of geminiviruses associated with cassava mosaic disease in Zambia por Mulenga, R.M., Legg, James P., Ndunguru, J., Miano, D.W., Mutitu, E.W., Chikoti, Patrick Chiza, Alabi, O.J.

“…Single-virus infections were predominant, occurring in 62.8% (ACMV), 5.8% (EACMMV), and 2.2% (EACMV) of samples relative to mixed-virus infections, which occurred in 19.5% (ACMV + EACMMV), 0.4% (ACMV + EACMV), and 0.9% (ACMV + EACMV + EACMMV) of samples. Phylogenetic analysis revealed the segregation of virus isolates from Zambia into clades specific to ACMV, EACMV, and EACMMV, further confirming the presence of all three viruses in Zambia. …”
