  The impact of pine plantations on water yield: A case study from the ecuadorian andes

  , IAHS AISH Publication, Pages: 225-228, ISSN: 0144-7815

  The conversion of natural grasslands to both pine plantations and cultivation was studied in the South American tropical alpine ecosystem called páramo. Hydrological and meteorological data were collected from four microcatchments, each with predominant vegetation,. The water balance was analysed in order to obtain the evapotranspiration of each catchment. The natural grasslands catchments had the lowest evapotranspiration. Evaporation in the cultivated catchment was about 20-40% higher, compared to 40-70% in the pine catchment. Flow duration curves were derived from the discharge time series and used to assess differences in the hydrological response of the catchments. The cultivated catchment is characterized by a significantly faster hydrological response than the natural catchment. The flow duration curves show higher peak flows and lower base flows. In the pine catchment, both peak and base flow are drastically lower because of higher local consumption. In the past, pine plantations have been widely considered as a viable method to improve the economic return of the páramo. In view of the importance of the páramo as a water supplier, these activities might need to be re-evaluated.

  Habitat fragmentation, variable edge effects, and the landscape-divergence hypothesis

  , PLoS One, Vol: 2, Pages: 1-8, ISSN: 1932-6203

  Edge effects are major drivers of change in many fragmented landscapes, but are often highly variable in space and time. Here we assess variability in edge effects altering Amazon forest dynamics, plant community composition, invading species, and carbon storage, in the world's largest and longest-running experimental study of habitat fragmentation. Despite detailed knowledge of local landscape conditions, spatial variability in edge effects was only partially foreseeable: relatively predictable effects were caused by the differing proximity of plots to forest edge and varying matrix vegetation, but windstorms generated much random variability. Temporal variability in edge phenomena was also only partially predictable: forest dynamics varied somewhat with fragment age, but also fluctuated markedly over time, evidently because of sporadic droughts and windstorms. Given the acute sensitivity of habitat fragments to local landscape and weather dynamics, we predict that fragments within the same landscape will tend to converge in species composition, whereas those in different landscapes will diverge in composition. This ‘landscape-divergence hypothesis’, if generally valid, will have key implications for biodiversity-conservation strategies and for understanding the dynamics of fragmented ecosystems.
