Models of individual tree mortality for trembling aspen, lodgepole pine, hybrid spruce and subalpine fir in northwestern British Columbia por Möller Pedersen, Sören

“…Tolerance to low growth decreases to a minimum at intermediate trees size for all species except for subalpine fir, where it decreases and remains low as trees growth larger. This is probably an effect of the ontogenetic characteristics of the individual species. …”

Inverkan av nederbörd, temperatur och frost på årsringens egenskaper hos boreal tall (Pinus sylvestris L.) por Grape, Sofia

“…Frost was found to influence ring development, though it can be assumed that the stand characteristics probably is of great importance regarding if/how frost affects the different ring parameters.…”

Skottbetning på granplantor i Kolmården : omfattning och påverkande faktorer por Almqvist, Kristoffer

“…It is thus possible that a preference for broad-leaved plants results in reduced browsing on the spruce-plants. This probably because the deers rather graze on the leaf rather than the spruceseedlings. …”

En kvalitativ utvärdering av det accelerometerbaserade hältdetektionssystemet "Lameness Locator" por Suneson, Ebba

“…The system comprizes two accelerometers and one gyrometer that sends data to a portable computer. The data analysed is then presented as a summary of asymmetries arising from the head or pelvis and which limb that can be connected to that asymmetry. …”

Abundance of syrphid larvae in willow plantations : role of habitat type, prey (Phratora vulgatissima) availability and interactions with other natural enemies por Johansson, Hans

“…This study shows that a higher diversity within the enemy-complex may have negative effects on the biological control of pests and that predators within the same guild are susceptible to predation in certain developmental stages. Hover flies are probably of little importance in the biocontrol of leaf beetles in situations with high densities of other natural enemies but have the potential to be particularly important as predators in recently harvested plantations i.e. plantations with low densities of heteropterans.…”

Privata markägares syn på vindskadeförebyggande åtgärder por Petersen, Axel af

“…The fact that the land owners in Småland thought that they should manage their forest differently in the future and that they thought that wind damage insurance is necessary was probably dependent on the fact that their forests was recently struck by wind damage.…”

Jaguar (Panthera onca) and puma (Puma concolor) hunting preferences, and their effect on cattle (Bos taurus), in Pantanal, Brazil por Fridell, Agnes

“…Most of the attacks occurred during the dry season, which is probably a result of farm routines rather than an environment effect. …”

Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden por Tylstedt, Viktor

“…The evaluation of spawning bed erosion attributed to spawning activity suggests that there is a spatial heterogeneity in erosion probabilities over a spawning bed. Erosion differed in magnitude between central-, downstream- and upstream sections, though no difference in movement between pebbles deployed along the edges of the bed compared to pebbles deployed in the middle of the stream could be proven. …”

The effect of low light intensities and red light on heart rate, blood pressure, respiratory rate and activity in dairy cows por Olsson, Pernilla

“…However no differences were seen due to the different light intensities and therefore cows are probably not stressed by low light intensities. This make sense since different light intensities is a normal part of their life during the day. …”

Inverkan av årstid för förstagallring på avverkningsskador i contorta och tall por Nolén, Karin

“…Today, stands with high-quality lodgepole pine are intended for production of both pulp wood and timber and are managed with one or more thinnings during the rotation period. SCA owns about 280 000 hectares of lodgepole pine, of which a large proportion is growing into age and height suitable for thinning. …”

Bosque secundarios como recurso para el desarrollo rural y la conservación en los trópicos de América Latina por Smith, J., Sabogal, C., Jong, W. de, Kaimowitz, D.

“…También formulamos la hipótesis de que los bosques secundarios son altamente variables en sus características ecológicas y en términos de objetivos y recursos de sus propietarios. Por tanto, es probable que las intervenciones requeridas sean altamente variables. …”

Beans (Phaseolus spp.)- model food legumes por Broughton, W.J., Hernández, G., Blair, Matthew W., Beebe, Stephen E., Gepts, Paul L., Vanderleyden, J

“…Unfortunately, the yields of common beans are low even by the standards of legumes, and the quality of their seed proteins is sub-optimal. Most probably this results from millennia of selection for stable rather than high yield, and as such, is a problem that can be redressed by modern genetic techniques. …”
