Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey por Kymmell, David

“…Context: A major effect of climatic change is the global increase in forest fires, which potentially creates an increase in food availability for herbivorous species. Also vegetation density and the numbers of tree logs increase in burned sites, and this is thought to influence the perceived risk of herbivore prey species, which affects their anti‐predator behaviour and thereby the patch utilization. …”

Träds inverkan på solstrålning mot bebyggelse : effekterna av trädval och placering i staden, sett ur ett hållbart perspektiv por Hansson, Clara

Microbregma emarginatum as an indicator for coniferous forests with high conservation values por Gille, Matilda

“…Sun exposure was estimated and a value representing the vegetation density was given each location. The results showed that Microbregma emarginatum is more abundant in protected areas where the proportion of trees with presence of the species was 51% higher compared to commercial forests. …”

More Stable Productivity of Semi Natural Grasslands than Sown Pastures in a Seasonally Dry Climate por Ospina, Sonia, Rusch, Graciela M., Pezo Quevedo, Danilo, Casanoves, Fernando, Sinclair, Fergus L.

“…Neither sown pastures nor semi-natural grasslands are productive towards the end of the dry season, indicating the potential importance of the widespread practice of retaining tree cover in pastures.…”

Relationships of stable carbon isotopes, plant water potential and growth: an approach to asses water use efficiency and growth strategies of dry land agroforestry species por Gebrekirstos, Aster, Noordwijk, Meine van, Neufeldt, Henry, Mitlöhner, Ralph

“…These results suggest that δ13C in tree rings can be useful in estimating historic changes in plant WUE and hence in screening drought tolerant species in the face of expected climate changes, as well as for assessing the functional diversity and risk reduction in mixed vegetation.…”

PPP exposure models for 3-D orchards considering spraying technologies in Southern Europe por Azimonti, Giovanna, Chueca, Patricia, Clementi, Emilio, Konstantinos P., Ferentinos, Garcerá Figueroa, Cruz, Grella, Marco, Luini, Mara, Marucco, Paolo, Mozzanini, Eric, Resecco, Marco, Tosti, Luca

“…Tree orchards like citrus, olives, apricot, peach and nuts, also known as 3D orchards, are typical crops of southern Europe (SEU) and present different vegetation characteristics (tree size, tree shape, foliar density, etc) and distinctive training systems and row and tree spacing in comparison with the ones used in apple and pear orchards in Central and Northern Europe, which are 3D orchards more typical of these zones. …”

Temporal variations in plant delta 13C values and implications for using the 13C technique in longterm soil organic matter studies por Diels, J., Vanlauwe, Bernard, Sanginga, N., Coolen, E., Merckx, Roel

“…Important and consistent within-year variations were, however, observed for legume tree prunings (up to 2.4‰) and weeds (up to 7‰), pointing to the need for frequent sampling within a single year if such seasonal variation is suspected. …”
