Status and epidemiology of maize lethal necrotic disease in northern Tanzania por Kiruwa, F.H., Mutiga, Samuel K., Njuguna, Joyce N., Machuka, Eunice M., Senay, S., Feyissa, T., Ndakidemi, P.A., Stomeo, Francesca

“…Through the survey, we showed that the prevalence of MLN differed across regions (P = 0.0012) and villages (P < 0.0001) but not across AEZs (P > 0.05). The study shows changing MLN dynamics in Tanzania and emphasizes the need for regional scientists to utilize farmers’ awareness in managing the disease.…”

Fine‐scale spatial genetic structure, mating, and gene dispersal patterns in Parkia biglobosa populations with different levels of habitat fragmentation por Lompo, Djingdia, Vinceti, Barbara, Konrad, Heino, Duminil, Jérôme, Geburek, Thomas

“…A good understanding of genetic variation and gene dispersal in tree populations is crucial for their sustainable management, particularly in a context of rapid environmental changes. West African Sudanian savannahs are being fragmented and degraded, partly due to expansion of crop cultivation and monocultures that reduce tree density and may impact pollinators. …”

Beyond fixes that fail: identifying sustainable improvements to tree seed supply and farmer participation in forest and landscape restoration por Valette, Michel, Vinceti, Barbara, Gregorio, Nestor, Bailey, Arwen, Thomas, Evert, Jalonen, Riina

“…Growing evidence suggests that constraints to the availability and quality of tree seed can undermine the success of forest and landscape restoration efforts and the delivery of associated benefits such as mitigating climate change and halting biodiversity loss. Past experiences to promote tree seed supply have frequently shown limited outcomes over time, partly because of unexpected, deleterious dynamics that emerged from the interventions themselves. …”
