Short- and long-term responses to seasonal drought in ponderosa pines growing at different plantation densities in Patagonia, South America por Gyenge, Javier, Fernandez, Marí­a Elena, Varela, Santiago Agustin

“…The following variables were studied: branch and stem hydraulic conductivity, canopy and stomatal conductance (gc, gs), transpiration (E), photosynthesis (Amax), wood δ13C (as a proxy of intrinsic WUE), leaf to sapwood area ratio (AL:As) and growth in the biggest (B) and the smallest (S) trees of high (H) and low (L) density stands. AL:As was positively correlated with tree size and negatively correlated with competition level, increasing leaf hydraulic conductance in H trees. …”

Higher establishment of nonnative trees with increased harvest intensity in strip cuttings por Dimarco, Romina Daniela, Nacif, Marcos E., Garibaldi, Lucas Alejandro, Nuñez, Martin Andrés

“…We conducted this study in a mixed forest dominated by Nothofagus antarctica, where we applied four strip harvesting levels: 0% (control), 30%, 50% and 70% percentage of vegetation removal in eight plots (1417.5 m2 each plot) Inside those plots, we had a total of 24 subplots (3 sites × 8 plots) were we sowed seeds of a total of six tree species, that can form dominant stands in the studied region. Three species were nonnative invasives in the region (Pinus ponderosa, Pinus contorta and Pseudotsuga mensiezii), and the other three were native species (Austrocedrus chilensis, Nothofagus obliqua and Araucaria araucana). …”

Pests in plantation forests: Challenging traditional productive paradigms in the Southern Cone of America por Villacide, Jose Maria, Fuentealba, Alvaro

“…The predominance of homogeneous stands composed of fast-growing exotic tree species under high-input regimes reduces biodiversity and increases vulnerability to both invasive and native pests. …”

Masting has different effects on seed predation by insects and birds in antarctic beech forests with no influence of forest management por Soler Esteban, Rosina Matilde, Espelta, Josep Maria, Lencinas, María Vanessa, Peri, Pablo Luis, Martínez Pastur, Guillermo José

“…Forest type (primary unmanaged, secondary-growth and managed stands) did not influence the amount of seed production nor masting patterns. …”

The allocation of assimilated carbon to shoot growth: in situ assessment in natural grasslands reveals nitrogen effects and interspecific differences por Xiao, Ying Gong, Berone, German Dario, Agnusdei, Monica Graciela, Rodríguez Palma, Ricardo Manuel, Schäufele, Rudi, Lattanzi, Fernando Alfredo

“…We used a mobile facility to perform steady-state 13C-labeling of field stands to quantify, in winter and autumn, the daily relative photosynthesis rate (RPR~tracer assimilated over one light-period) and A shoot (~tracer remaining in shoots after a 100 degree days chase period) in four individual species with contrasting morpho-physiological characteristics coexisting in a temperate grassland of Argentina, either fertilized or not with nitrogen, and either cut intermittently or grazed continuously. …”

Growth and Productivity of Coffea arabica var. Esperanza L4A5 in Different Agroforestry Systems in the Caribbean Region of Costa Rica por Morales Peña, Victor Hugo, Mora Garcés, Argenis, Virginio Filho, Elias de Melo, Villatoro Sánchez, Mario

“…In particular, the tree coverages associated with chemical and physical fertilization achieved the highest growth and production rates, with A. excelsum + E. poeppigiana and H. courbaril + E. poeppigiana standing out with maximum mature cherry productions of 3.35 t/ha and 3.28 t/ha, respectively. …”

Bokhögstubbar i Klåveröds strövområde : utbredning, egenskaper och betydelse för rödlistade vedlevande skalbaggar por Holmström, Emma

“…Furthermore the snags in northern Klåveröd are separated from the southern parts by a barrier of conifer stands of one kilometre width. The lack of continuity in dead wood and the limited dispersal ability from known habitats is the primary difference between the two parts of Klåveröd and also the gradient between Klåveröd and the national park.…”

Objektiv rörelseanalys : ett stöd vid den visuella bedömningen av hälta hos hund? por Ekström, Christoffer

“…In the literature it is described how a clinical examination can be performed, based on general clinical-, orthopedic- and neurological examination, and visual evaluation of the dog when standing and during motion. For research, objective gait analysis systems are also used to study clinically healthy and lame dogs during motion. …”

Mätning av stamdiameter med markstående scanner por Sigfridsson, Anders

“…To enhance optimisation of timber flow from forest to industry Moore efficient methods for measuring tree stems of standing trees are needed. The performance of terrestrial laser scanners have improved and these could possibly be used within forestry in the future. …”

Mineral elements in clover- and grass forage in Sweden por Lätt, Kajsa

“…Forage is the main feed giving to ruminants and knowledge about the mineral content in the forage is important to avoid deficiencies or toxicities and to get a good under-standing about the mineral balance of the farm. …”

Tillväxteffekter på lång sikt av gödsling i äldre tallbestånd por Alajärvi, Hannes, Engström, Oskar

“…It was done by using data from field trials to compare fertilized plots with control plots, and with that get results whether fertilization influences growth or not in a longer period, but also how production and height development acted together. The stands in the two fields trials were fertilized during the 1960 and 1970s, and the long-term effects was investigated in a period of 40 – 50 years after the fertilization was done. …”
