The following study investigates the timing and mechanism of impact of Swiss needle cast on Douglas-fir (Pseudotsuga menziesii) needle physiology (i.e. gas exchange). Swiss needle cast is a foliar disease caused by the fungus Phaeocryptopus gaeumanni

Existe preocupación por el posible uso excesivo de agua de las forestaciones con especies exóticas de rápido crecimiento en comparación con las especies nativas a las cuales reemplazan en la región NO de la Patagonia. Debido a ello, se han reali

Using the “photochemical reflectance index” (PRI) as a measure of xanthophyll pigment activity and photosynthetic light-use efficiency, we examined physiological responses to diurnal illumination in mature forest stands. In a Douglas-fir forest i

Stable isotopes can be a valuable tool for tracing the redistribution, storage, and evaporation of water associated with canopy interception of rainfall. Isotopic differences between throughfall and rainfall have been attributed to three mechanisms:

Distinct aggregations of fungal hyphae and rhizomorphs, or "mats" formed by some genera of ectomycorrhizal (EcM) fungi are common features of soils in coniferous forests of the Pacific Northwest. We measured in situ respiration rates of Piloderma mat

Although much is known about drivers of productivity in Douglas-fir and red alder stands, less is known about how productivity may relate to stand transpiration and water use efficiency. We took advantage of a 15-year-old experiment involving Douglas

Ecohydrological connectivity is a system level property that results from the linkages in the networks of water transport through ecosystems, by which feedbacks and other emergent system behaviours may be generated. We created a system dynamics model

The water balance equation dictates that streamflow may be reduced by transpiration. Yet temporal disequilibrium weakens the relationship between transpiration and streamflow in many cases where inputs and outputs are unbalanced. We address two criti

Exotic ponderosa pine (Pinus ponderosa Doug. ex. Laws) is being planted for timber production in the natural distribution area of cordilleran cypress [Austrocedrus chilensis (D. Don) Pic. Serm. et Bizzarri] in the forest-steppe ecotone at the base of

The connectivity of ecohydrological and biogeochemical processes across time and space is a critical determinant of ecosystem structure and function. However, characterizing cross-scale connectivity is a challenge due to the lack of theories and mode
