The trends in these species are probably linked to long-term changes in land use leading to, respectively, increasing habitat suitability for increasers and the loss and fragmentation of habitats for decreasers (Warren et al. ; Opdam and Wasscher ; Pöyry et al. ). Thus, our results underline the importance of not overestimating Cited by:

Given the advantages of digital repeat photography in terms of logistics, consistency, continuity and objectivity, we expect growing archives of landscape images to become important data streams for phenological research. One crucial aspect for long-term measurements is the stability of the measured by: Interpreting Landscape Change in High Mountains of Northeastern Oregon from Long-Term Repeat Photography Jon M.

As might be expected, most photosets contained more than one vegetation type. Grasslands were depicted in photosets, sagebrush in 99, pinyon-juniper inmountain brush in 72, aspen in 37, conifers inblackbrush in 71, and woody riparian species. used repeat photography as a scien-tific tool in the United States.

Outstanding Southwestern examples are the seminal The Changing Mile (Hastings and Turner ), A Legacy of. Long-term MODIS vegetation index records were used to extract regularly-repeating seasonal and interannual greenness cycles in Hawaiian ecosystems using harmonic analysis.
With two vegetation indices, NDVI and EVI, the MODIS system provided an opportunity to combine the two measures and create a hybrid approach to the leafFile Size: KB. For the entire lake population, temporal trends in Secchi depth from to were positive (average of all lake specific long-term trends), suggesting an overall increase in water clarity.
The posterior estimate for the mean slope, (Eq. 1) wasindicating that Secchi depth, on average, has been increasing by % per year (95%. Interpreting long-term trends in Blue Mountain ecosystems from repeat photography.
General Technical Report PNW, USDA Forest Service Pacific Cited by: The sustainable use and management of important tropical coastal ecosystems (mangrove forests, seagrass beds and coral reefs) cannot be done without understanding the direct and indirect impacts of man.
The ecosystem's resilience and recovery capacity following such impacts must be determined. The efficacy of mitigation measures must also be by:. Soil testing can also be used to monitor long-term trends, but special precautions (e.g., uniform depth and locations of sampling, and method of analysis) are needed.
Units of measurement: Most laboratories use metric units, such as µg/g (µg g-1) or mg/kg (mg kg-1), for expressing their extraction values. Both units are equivalent to ‘parts.Ecosystems – Download PDF Negative relationships between species richness and evenness render common diversity indices inadequate for assessing long-term trends in butterfly diversity.
