    Which environmental factors control gully (ephemeral or permanent) initiation and evolution in Arid lands?

    Key words: Flash flood - Gully and Rill -Land Use - Vegetation covers - Topography.

    How can i combine all in one model? And how can i quantify these factors?  

    Maria V. Kozlova

    Dear Amr Saleem, The end of my post missed so trying to proceed:

    Hydrological cycle in all water bodies (including groundwaters) is very important factor,  not only flash floods caused in abundant precipitation. Evaporation drived by temperature dynamics  and other factors is also valuable too. Note that exact parameters had to be taken into account  depend on certain location. Very important point is a scale. Drivers of short-term (seasonal) dynamics usually differ from annual, decimal trends  as well as dymamic character itself. human impact including land use is most unpredictable factor. Remotely sensed (satellite) data help in estimation of most referred factors (direct or ondirect) for model verification. This is suggested in accordance to our experience. Honestly speaking, the models you suggest are really complicated   I suddenly found the reference I was giong to share: https://www.researchgate.net/publication/270769761_Spatially_explicit_estimation_of_soil-water_resources_by_coupling_of_an_eco-hydrological_model_with_remote_sensing_data_in_the_Weihe_River_Basin_of_China

      ABSTRACT: Soil-water resources are key components for agriculture and have great potential. Strategic and significant efforts are, therefore, required to make full use of soil-water resources, especially in dry or semidry areas.We coupled a soil-water model with remotely sensed data and associated techniques to analyze the spatial-temporal dynamics of soil-water resources in the Weihe River Basin in China. The moderate-resolution imaging spectroradiometer (MODIS), Chinese meteorological satellite precipitation estimation data (FY-2), and global land data assimilation system (GLDAS) products were used for spatial land surface characteristics interpretation and model parameters derivation. The modeling results were compared and validated using data from a nearby observation site. The average soil-water resources of the Weihe River Basin vary between 40 and 100 mm during the simulation period from January to December, with a maximum of 99 mm appearing in August and a minimum of 38 mm in December. Forest land was characterized by large soil-water resources, with an average annual rate of 1094.7 mm. Farmland and grassland exhibited low values, with average annual rates of 986.7 and 893.5 mm, respectively. The results could be taken into consideration for soil-water resources management.

    How do I interpret ecosystem indices from ecopath models?

    I am reviewing literature about ecosystem changes in Lake Victoria (East Africa). I know, from Odum's 24 indices of ecosystem development and maturity, that values of primary production to respiration ratio <1 suggest eutrophication, while values >1 suggest an immature system. However, in one of the papers, where authors were describing the trophic characteristics of Mwanza gulf (Lake Victoria), using ecopath, they reported a primary production to respiration ratio >500. Question 1: Is this value realistic? Question 2: Does this mean that Mwanza gulf is not eutrophic? Question 3: How am I supposed to interpret this value based on principles of ecosytem development?

    Naveen Kalra

    Dear Dr Raj/Nalugonza

    valuable information provided on the link, this prompts me to think on agro-ecosystem indices through ecopath models through simulation techniques. This process might aid in climate change impacts evaluation, NRM for sustainable agriculture.

    How can I calculate daily NPP using whole season daily NEE?

    Now there are a lot of ways to measure NEE for terrestrial ecosystems, a lot of data on NEE from eddy covariance and transparent chambers. In turn, a lot of models use NPP for different calculations. Do you know how to calculate NPP from NEE? I need to do this separation for wetland. It is possible to estimate ecosystem respiration using night NEE data, but not the autotrophic respiration, which is necessary to estimate NPP.

    Serge Rambal

    Using a constant ratio may be useful at yearly time scale. But at a daily time scale you have to estimate the heterotrophic respiration (NPP = NEP + Rh). Based on GPP we have to have the estimate of the autotrophic respiration perhaps easier to measure or simulate.

    What are the different methods for estimating biomass density of forest ecosystem?

    Natural forests store a large quantity of carbon, and there is currently great interest in assessing that quantity accurately, since when forests are cleared the carbon is converted to carbon dioxide in the atmosphere. I want  to know the methods for  biomass estimation but  without using remote sensing techniques.

    Can anyone comment on this map made by me presenting increased likelihood of methane in the southern Baltic?

    The map is  calculated on  the basis of  acoustic  observations of  the methane expulsions and  correlated type  of the  seabed - the  chart  of the  most probable  zones of  methane presence was calculated by me for  the  southern Baltic  Sea.  The methane  area is  well correlated with deeper stagnation areas.

    thanks Jan Schulz. The area is  indicating the  horizontal range  of  methane ebulitions, based on  acoustic  observations and  measurements of the  sebed  properties. The area can  be  correlated with  the  small dynamics  of the  currents and correlated very  soft  sediments. Generally  it  is indicating  the  deposits of the decomposition of  materials produced  due  to  increase  of the  eurtophisation.

    Is the green house effect or global warming responsible for climate change?

    What are the main causes of climate change? How do they influence climate change, and in what ratio? 

    Dimis Poulos

    Herbert I have deeply analyzed the current subject, though the direct effect of electricaĺy charged particles found in cosmic rays is helping to cloud creation, it is the electrons from the earth that have the important role in cloud formation in earth as they are pushed upwards from the geomagnetic field which is coupled to the earth-venus resonance oscillating solar wind. For at least as far as surface temperatures concerns.

    How can I construct a trophic model for an estuary using ECOPATH?

    Dear Friends, I am trying ECOSYSTEM based modelling of Zuari Estuary (Goa, Southwest coast of India) with about 24 ecological groups. The basic inputs were provided and the model was mass balanced (adjusting the biomass of four groups) with Eco trophic efficiencies were kept under one. However, the respiration values are showing negative values and it is given as an error in result display. How should i adjust the input data (Diet matrix or Biomass which has to be adjusted) for making the respiration values to positive and within one.

    Pierre Failler

    Hello Sreekanth, 

    Please contact our colleagues in China, for instance Ying Wang at 03ying@163.com as they have been working for many years now on the development of an ecosystem model for the Pearl River Delta in China. A few papers have been published out of it. I can send you the papers if you want. Let me know.

    What are estimated wetland aeration costs (£/kg BOD5) removed in full scale artificially aerated wetlands?

    Working on methods to optimize field scale artificially aerated wetlands for the application of de-icer contaminated run-off at airports. Aeration is required to improve performance (i.e the removal of organic compounds) but what are the economics regarding the cost of aeration in full scale systems?

    Yaakov Anker

    We did some research on wetland application for runoff (urban and industrial) treatment. The most cost efficient configuration was a constructed wetland, which is actually more of a bio-filter, with several sequential fixed strata reactors. The best aeration system was found to be, recycling the horizontal outlet to a vertical flow through a ventury aerator. 

    Hope it helps, for specific cost estimation more details such as cost of electricity, flow rate, organic load, etc. are needed.

Ostroumov (Moscow University), Introduction to Biochemical Ecology (Moscow University Press, Moscow, 1986, 176 pages) - is a really innovative, insightful, useful book ahead of its time. It is the first book on the subject of biochemical ecology in the world scientific literature including scientific publications in the U.S.A., Russia, U.K., Germany, France, Japan, Australia, and other countries. This book created a new science of biochemical ecology. The book covers two major areas of biochemical ecology: (1) natural chemicals that are produced by organisms and involved in interactions among organisms; (2) biochemical transformation of xenobiotics and chemical pollutants. The book formulated new useful and fundamental concepts and proposed new terminology, e.g. ecological chemomediators and ecological chemoregulators. It is the first book that formulated a list of biospheric and ecological functions of natural chemicals produced by organisms. A new concept of the biosphere as an ecological-biochemical continuum was proposed. The book was translated into Polish and Bulgarian. A new, second edition of this book was published in Russian under the title 'Introduction to Problems of Biochemical Ecology' (Moscow, Nauka Press, 1990). This unique, useful, valuable, book is an excellent contribution to ecological sciences.

    How can I quantify the cultural / spiritual values of ecosystem services?

    I am trying to map the ecosystem services values of a multi-functional wetland.

    I am using monetary values to convert the concerned services into monetary units for convenient overlapping in the following mapping step. So far, provisioning, regulating and supporting, all of which provide directly or indirectly products having market goods, making them convertible into monetary units. As for cultural values i.e. temples, landscapes, values. I am concerned about the hidden values that could not be captured by stated preference methods. 

    Please kindly help with your experience and expertise

    Amanda Bentley Brymer

    Have you looked into Greg Brown's research on mapping ecosystem services? His work focuses on participatory mapping - engaging the public and/or stakeholders in the mapping process. Whether you are working with the public or not, his work also focuses on ecosystem services, including cultural services. Perhaps this paper or references within it will help.

      ABSTRACT: This study proposes an empirical methodology for modelling and mapping the air temperature (mean maximum, mean and mean minimum) and total precipitation, all of which are monthly and annual, using geographical information systems (GIS) techniques. The method can be seen as an alternative to classical interpolation techniques when spatial information is available. The geographical area used to develop and apply this model is Catalonia (32 000 km2, northeast Spain). We have developed a multiple regression analysis between these meteorological variables as the dependent ones, and some geographical variables (altitude (ALT), latitude (LAT), continentality (CON), solar radiation (RAD) and a cloudiness factor (CLO)) as the independent ones. Data for the dependent variables were obtained from meteorological stations, and data for the independent variables were elaborated from a 180 m resolution digital elevation model (DEM). Multiple regression coefficients (bn) were used to build final maps, using digital layers for each independent variable, and applying basic GIS techniques. The results are very satisfactory in the case of mean air temperature and mean minimum air temperature, with coefficients of determination (R2) between 0.79 and 0.97, depending on the month; in the case of mean maximum air temperature, R2 ranges between 0.70 and 0.89, while in the case of precipitation, it ranges between 0.60 and 0.91.

    I had the same problem. The procedure described here did not work for me, maybe for the limitations of dealing with a very huge number of resulting vector point after the first step.

    I managed to get what I was after using another approach. Hope this will be useful sometime in the future to anyone jumping here:

    (1) I loaded a DEM and a shape file corresponding to the same area;

    (2) I created a fishnet (with the ArcGIS tool) with size 500mX500m, making sure to tick the 'create labels';

    (3) I added x and y values to each generated point;

    (4) interpolated the x values by IDW, snapping the resulting raster to the DEM, and using the same processing extent of the region's shapefile. Same applies for y.

    DONE

    Hope this helps

    Can anyone suggest some methodology to understand the succession or dynamics of riparian trees and woody vegetation?

    I have collected data from 4 small mountain streams with permanent flow or with dry months. I took between about 74 plots with 40mx 20m size, collecting data related to tree species richness, number of individuals, height, DBH, tree distance from river bank, and regeneration . Site characteristics and water regime in the river is also recorded, as well as number of dry months (if any). My aim is to study  the relationship between actual dominant tree or shrub species, and their regeneration, to better understand successions (if any). Please provide links or publications if available as I have limited access.

    Are physically-based land surface models less skillful than simple statistical models using linear regression?

    See results from the international benchmarking project, PLUMBER (PALS Land Surface Model Benchmarking Evaluation Project).

    https://ams.confex.com/ams/94Annual/webprogram/Paper234348.html

    Imtiaz Dharssi

    The Paper "The plumbing of land surface models: benchmarking model performance" is available from http://journals.ametsoc.org/doi/abs/10.1175/JHM-D-14-0158.1 .

    My favorite quotes from the paper:

    "the indifferent performance of the models at sites with restricted soil moisture questions the current methods used in the LSMs for representing the stomatal control on transpiration"

    "the LSMs do not appropriately use the information available in the atmospheric forcing data when estimating QH and QE"

    The full Abstract:

    The PALS Land sUrface Model Benchmarking Evaluation pRoject (PLUMBER) was designed to be a land surface model (LSM) benchmarking intercomparison. Unlike the traditional methods of LSM evaluation or comparison, benchmarking uses a fundamentally different approach in that it sets expectations of performance in a range of metrics a priori – before models simulations are performed. This can lead to very different conclusions about LSM performance. For this study both simple physically based models and empirical relationships were used as the benchmarks. We performed simulations with 13 LSMs using atmospheric forcing for 20 sites and then examined model performance relative to these benchmarks. Results show that even for commonly used statistical metrics, the LSMs’ performance varies considerably when compared to the different benchmarks. All models outperform the simple physically-based benchmarks, but for sensible heat flux the LSMs are themselves outperformed by an out-of-sample linear regression against downward shortwave radiation. While moisture information is clearly central to latent heat flux prediction, the LSMs are still outperformed by a three variable non-linear regression that uses instantaneous atmospheric humidity and temperature in addition to downward shortwave radiation. These results highlight the limitations of the prevailing paradigm of LSM evaluation that simply compares a LSM to observations and to other LSMs without a mechanism to objectively quantify our expectations of performance. We conclude that our results challenge our conceptual view of energy partitioning at the land surface.

    Where can I find the definition of the geolocation fields of the MODIS Level 2 data?

    I want to know in which way the data points are mapped. In the png-file you see a calculation of the coordinates using the geolocation info. I need the corner coordinates of each square box. In the file it looks like the coordinates are in the middle but often two data points are closely located to each other.

    Does anybody know where I can find a solution for my problem? Or maybe a tool which can transform the coordinates? On "http://modis-atmos.gsfc.nasa.gov" I dont find anything yet.

    I totally agree with Maroles answer further i want to share that ,their is a different Algorithm Theoretical Basis Document (ATBD) for every product of MODIS. You can confine your search to the actual  data your are dealing with and also make sure you are searching exactly the same version and level of your data.

    Dear Mohammad

    As you know acidification of the oceans depend on some factors:

    1- Concentration of carbon dioxide in atmosphere

    2- Absorption of CO2 by organisms

    3- Carbon dioxide cycle in ocean

    These factors control the PH of ocean which changes by variation of deph.

    I recommend to see the link below:

    What are the emerging issues for urban environments and ecosystems i.e. potential threats and opportunities that are currently poorly recognized?

    We are having a workshop in Auckland in 2 weeks to consider urban pressures on the horizon.  The challenge is to think of new ideas, or issues poorly studied, rather than the usual problems or exacerbators of the usual problems. Your ideas would be welcome.

    Sure Jaqueline; we pulbished a few articles. Will find your e-mail and send.

    Greetings

    Can you suggest some good papers with regard to modelling interactions among ecosystem services?
    E.g., methods to analyse interactions among variables in complex interacting systems.

    Why did the IUCN decide this 6 meter limit for wetland? and not 5 meters or 7 meters ?

    For wetland IUCN adopted the following definition in 1971 (4; 2) :
    “. . . areas of marsh, fen, peatland or water, whether natural or arti-
    ficial, permanent or temporary, with water that is static or flowing,
    fresh, brackish, or salt including areas of marine water, the depth of
    which at low tide does not exceed 6 meters.”

    Lawrence Handley

    6 meters was used in classification scheme for marine and estuarine tidal systems, primarily for mapping.  The preponderance of information in the 1970's showed benthic growth declining after 6 meters of water depth, on an average, due to light attenuation, latitude, and other factors.  2 meters water depth is the standard used in freshwater wetland classification, particularly between lim ethic (greater than 2 m depth) and littoral (less than 2 m water depth. 2 meters was used as the breakpoint from expertise and literature in the 1970's and early 1980's as the max depth from which rooted emergent herbaceous vegetation will grow to above the waters surface.  There is more recent evidence from reports that 3 meters may be an acceptable depth.

    Have the models developed by Craig-Gordon (1965) and Merlivat-Jouzel (1979) been compared in an ecosystem model or GCM?

    Two basic parameterization schemes have been utilized for predicting the isotopic enrichment of surface waters during evaporation. I am looking for studies or models that compare both approaches. C-G typically uses turbulence-dependant weighted kinetic fractionation whereas M-J uses separate wind-speed-dependent algorithms for smooth and rough surfaces.

    Please find the enclosed paper, where they compared  MJ79 and CG65 for terrestrial evaporation.

    I also made a note comparing the fractionation factor from two approaches.  I am attaching that file too.

    I am curious to know whether the MJ79 is applicable  to large lakes?

About Ecosystem Modeling

An ecosystem model is an abstract, usually mathematical, representation of an ecological system, which is studied to gain a deeper understanding of the real system. Ecosystem models are formed by combining known ecological relations with data gathered from field observations. These model systems are then studied in order to make predictions about the dynamics of the real system. Often, the study of inaccuracies in the model (when compared to empirical observations) will lead to the generation of hypotheses about possible ecological relations that are not yet known or well understood. They also enable the simulation of ecological processes over very long periods of time. Ecosystem models have applications in a wide variety of disciplines, such as natural resource management, ecotoxicology and environmental health,agriculture, and wildlife conservation. (Wikipedia)
