Trait‐based approaches for guiding the restoration of degraded agricultural landscapes in East Africa por Lohbeck, M., Winowiecki, Leigh Ann, Aynekulu, Ermias, Okia, C., Vågen, Tor-Gunnar

“…Each LDSF site is a 10 × 10 km landscape in which vegetation cover and erosion prevalence were measured, a tree inventory was carried out, and topsoil (0–20 cm) samples were collected for organic carbon (SOC) analysis in approximately 160 × 1,000 m2 plots. …”

Long-term response of groundcover components to organic and conventional weed control in shaded and open-sun coffee in Nicaragua por Staver, C., Juventia, S., Navarrete, E., Navarrete, L., Sepulveda, N., Barrios, M.

“…Over 11 years, treatments with trees compared to full sun coffee showed near absence of bare soil (P < .001) and increasing presence of leaf litter (P < .001) and cover vegetation (P < .001), especially in the first 8 years. …”

Neighbourhood effects as a plant defence against ungulate herbivory por Koster, Bregje

“…Concluding, neighbourhood effects differ between foraging scales and tree species and are strongly influenced by the palatability of the focal trees. …”

Forage ofering and seasonal intake comparisons to evaluate European rabbit threat in Nothofagus forests of southern Patagonia por Huertas Herrera, Alejandro, Toro Manriquez, Monica, Borrelli, Laura Beatriz, Lencinas, María Vanessa, Martinez Pastur, Guillermo José

“…Results: Forage intakes revealed changes in plant life form consumption across vegetation types, where intake pressure was considerably diferent for tree regeneration (p=0.001), graminoids (p=0.001), and hemiparasites (p=0.001). …”

Natural regeneration on clear cuts in Southern Sweden por Jónsson, Jón Ásgeir

“…The aim was to examine the effects of soil treatment, fencing and distance from broad-leaved forest on the natural regeneration of woody species and on the ground vegetation. All naturally regenerated tree saplings that had reached a height of 30 cm were recorded and the ground vegetation was assessed with a cover estimate. …”

Sistemas tradicionales de gestión del bosque tropical en Indonesia: ecología y prácticas silviculturales por García Fernandez, C.

“…Both are forest resources classified as NTFPs. Benzoin is a tree characteristic of mature forest that requires shade in the first stages of growth, therefore it is planted under forest cover once the undergrowth vegetation have been eliminated. …”

Ecosystem Services and Biodiversity in a Rapidly Transforming Landscape in Northern Borneo por Labrière, N., Laumonier, Y., Locatelli, Bruno, Vieilledent, G., Comptour, M.

“…Because industrial agriculture keeps expanding in Southeast Asia at the expense of natural forests and traditional swidden systems, comparing biodiversity and ecosystem services in the traditional forest–swidden agriculture system vs. monocultures is needed to guide decision making on land-use planning. Focusing on tree diversity, soil erosion control, and climate change mitigation through carbon storage, we surveyed vegetation and monitored soil loss in various land-use areas in a northern Bornean agricultural landscape shaped by swidden agriculture, rubber tapping, and logging, where various levels and types of disturbance have created a fine mosaic of vegetation from food crop fields to natural forest. …”

Vad styr förekomsten av sälg och asp? por Karlsson, Kristin

“…However, the occurrence of lichens was not related, neither to ground moisture nor to vegetation type around the tree. A positive relationship was found between lichen-frequency and the DBH of the trunk. …”

Changes in spider diversity through the growth cycle of pine plantations in the semi-deciduous Atlantic forest: The role of prey availability and abiotic conditions por Munevar Lozano, Ana Katerinne, Rubio, Gonzalo Daniel, Zurita, Gustavo Andres

“…We expected that the increase in environmental similarity (vegetation, prey availability) between native forest and tree plantations through the plantation growth cycle would promote its use by native spider species. …”

Climate change adaptation in and through agroforestry: four decades of research initiated by Peter Huxley por Noordwijk, M. van, Coe, R., Sinclair, Fergus L., Luedeling, Eike, Bayala, Jules, Muthuri, Catherine W., Cooper, P., Kindt, R., Duguma, L., Lamanna, C., Minang, Peter A.

“…Agroforestry (AF)-based adaptation to global climate change can consist of (1) reversal of negative trends in diverse tree cover as generic portfolio risk management strategy; (2) targeted, strategic, shift in resource capture (e.g. light, water) to adjust to changing conditions (e.g. lower or more variable rainfall, higher temperatures); (3) vegetation-based influences on rainfall patterns; or (4) adaptive, tactical, management of tree-crop interactions based on weather forecasts for the (next) growing season. …”
