ABSTRACT Este artículo presenta un resumen de la puesta en común que un grupo de alumnos hicieron para un curso de doctorado del programa "Cambio global y desarrollo sostenible" de la Universidad de Alcalá. En los últimos años se ha detectado un cambio en las variables climáticas motivado por factores biofísicos y humanos. La respuesta de los sistemas biológicos a los vectores de cambio (aumento de la temperatura media y concentración de CO2, cambio de los patrones de precipitación y aumento de la severidad y frecuencia de eventos extremos) ha sido experimentada por los distintos niveles de organización -ecosistema y comunidad, población e individuo- de los sistemas biológicos de ambientes acuáticos y terrestres. También los procesos ecológicos son influidos por el cambio climático y determinan, junto a la capacidad de adaptación, los efectos que los cambios generan sobre la estructura y función de los sistemas biológicos. Este trabajo pone de manifiesto la complejidad asociada al estudio de los efectos biológicos del cambio climático en los sistemas biológicos intervenidos en mayor o menor medida por el hombre.

    ABSTRACT: The biological diversity within soils and sediments may be orders of magnitude greater than that above the surface, but has not been fully documented in any system (Anderson 1995, Wall Freckman In soils, only an estimated 10% of protozoa and 5% of mite species have been taxonomically described (Brussard etal.1997), and in marine sediments, Snelgrove estimate that just 0.1% of species are described. Although the identity of the vast majority of species in soil and sediments is unknown, we do know that assemblages of species("functional groups") regulate vital ecosystem properties such as decomposition of wastes, renewal of soil fertility, and purification of water (Brussard; Palmer; Snelgrove; Covich; Groffman & Bohlen 1999; Snelgrove 1999). A major scientific challenge is to evaluate the significance of the great diversity of life in the soils and sediments for ecosystem function and ecosystem goods & services. For example, we must identify "keystone" species (those species that have a disproportionately large effect on ecosystem function) and how soil and sediment biodiversity and the ecosystem functions they regulate respond to environmental or disturbance gradients. In 1995 the Scientific Committee on Problems of the Environment (SCOPE) established the Committee on Soil and Sediment Biodiversity and Ecosystem Functioning (SSBEF) to synthesise available information and identify gaps in knowledge and research needs in this area. The first meeting of the SSBEF committee revealed the great extent to which activities of organisms dwelling within soils and sediments or litter layer (here defined as below-surface biota) involve physiological or ecological interactions with organisms in above-surface habitats (e.g. the vegetation, the water column, or even the watershed for freshwater sediment organisms). These cross-surface interactions include decomposition of leaves by invertebrates and microbes in soil and sediments, nutrient cycling from below-surface bacteria to macrophytes and phytoplankton, mutualistic interactions between mycorrhizae and plants, and predator-prey interactions. Importantly, this interconnectivity appeared to be a crucial element of many vital ecosystem processes in all three domains: terrestrial, freshwater and marine (Wall Freckman However, the significance of biological diversity above and below the surface of soils and sediments, could not be ascertained at the first workshop. Synthesising knowledge of the connections between above-surface and below-surface biodiversity was considered a priority to be addressed at a second workshop, since it would help to 1) yield information on keystone

    ABSTRACT: The temporal and spatial patterns of summer extreme low flows and effects on stream ecosystems were evaluated throughout the Otago Region of the South Island of New Zealand during a severe drought in 1998–1999. Flows, water quality, and aquatic biology were monitored bimonthly at 12 locations as part of a long-term regional monitoring programme and results were evaluated and compared among summer 1998–1999 and all previous summers, as well as among three major subregions. Flows during the drought were extremely low for prolonged periods in many locations, particularly in North Otago. At most sites temperatures were slightly higher for a longer period than during other summers. In predominantly agricultural/pastoral catchments, widespread bacterial contamination of streams occurred due to increased livestock use of watercourses and decreased dilution during low flows. Concentrations of other contaminants derived from non-point sources, including nitrogen, phosphorus, and sediment, decreased in many locations due to the lack of rainfall and runoff events. Electrical conductivity generally increased as a result of the lack of dilution and increased evaporation and groundwater inputs. Overall water quality was worst in agricultural catchments in South Otago, and returned to conditions prior to the low flows by late autumn in most areas.The diversity of benthic macroinvertebrate communities and number of sensitive taxa decreased somewhat in many locations, but the magnitude and duration of these effects were not great. Differences between summer 1998–1999 and other periods, and among subregions, were not significant. Although some differences in low flows and effects on stream ecosystems across a range of landscapes and catchments can occur, the rapid recovery of water quality and benthic macroinvertebrates in most locations indicates that many streams are resilient to extreme low flows and drought with minor long-term effects.

    ABSTRACT: General circulation models (GCM) predict that increasing levels of atmospheric carbon dioxide (CO2) and other greenhouse gases will lead to dramatic changes in climate. It is known that the spatial variability of species richness over continental spatial scales is strongly correlated with contemporary climate. Assuming that this relationship between species richness and climate persists under conditions of increased CO2, what changes could we expect to occur in terms of species richness? To address this question, I used observed relationships between contemporary richness and climate, coupled with climate projections from five GCM, to project these future changes. These models predict that the richness of vertebrate ectotherms will increase over most of the conterminous United States. Mammal and bird richness are predicted to decrease in much of the southern US and to increase in cool, mountainous areas. Woody plant richness is likely to increase throughout the North and West and to decrease in the southwestern deserts. These projections represent changes that are likely to occur over long time scales (millennia); short-term changes are expected to be mainly negative.
