I established transfer functions with PAST 4.01, and I would like to input some downcore data (lake sediments, diatoms) to reconstruct past environmental change quantitatively using the transfer function.
However, I don't know how to put the data into the transfer function in PAST.
Does anyone know how to do that?
Or I appreciate any other suggestions for methods to build a transfer function and its application.
Thank you very much in advance!
I would like to know your opinion about what are currently the greatest unsolved problems or opportunities for further research in palaeoclimatology.
Its going to be a huge shift for marketers, tracking identity is tricky at the best of times with online/offline and multiple channels of engagement - but when the current methods of targeting, measurement and attribution get disrupted, its going to be extremely difficult to get identity right to deliver exceptional customer experiences whilst getting compliance right.
We have put our framework and initial results show promising measurement techniques including Advanced Neo-classical fusion models (borrowed from Financial industry, Biochemical Stochastic & Deterministic frameworks) and applied Bayesian and Space models to run the optimisations. Initial results are looking very good and happy to share our wider thinking thru this work with everyone.
Link to our framework:
Please suggest how would you be handling this environmental change and suggest methods to measure digital landscape going forward.

I'm an Undergraduate student on the search for a research topic which has to involve any ecosystem service(s) and a response to environmental change. I'm looking for raw quantitative data sets (I need to do a stats test with it) which can inspire me, but I have had no guidance as to where I can find such data online. I don't have any specialist software for this, nor am I expected to use any. Would prefer UK data if possible.
Thank you in advance!
Societies are undergoing continual and sometimes rapid changes. At the same time, we are facing the biggest environmental challenge. How are the two related?
I am in need of article that link genetics or biotechnology to environmental changes, biodiversity and ecosystem services
I am interested in the study on geo-environmental changes and modelling of ecosystems using satellite images and gis tools. your suggestions are welcome.
With the ongoing global changes in the climate, several schools are including environment changes effects on health and disease. Are you giving a place in the curriculum to this critical area?
Green cover is reducing all over the world and temperature is increasing concurrently as well.There are so many factors are responsibe for the rise of temperature & Humidity), but what's the effect of tree/forest cover reduction on it?
- Is there any direct relationship between tree/forest cover reduction on temperature and humidity? (i suppose yes, there is)
- How to calculate the effect of tree on temperature and humidity?
NB: Article reference would be appriciated
If there is a significant relationship between these. What is the nature of the relationship? Do other factors like political factors affect this relationship? What can you say about the contribution of environmental change to violent conflict in Nigeria?
Dear Tom, I have received information about your project from Leszek Mackiewicz who cooperates with us. Justyna Żabicka’s PhD thesis under my supervision is focused on: Viola epipsila (2n=4x=24)-V. palustris (2n=8x=48) complex taxonomically very critical group of species in whole circumboreal range of distribution. The genetic diversity of this complex, in addition to the changing climate and habitat loss (these species occur in flooded forests) may also be influenced by hybridization. These two closely related species cross easily in nature due to weak isolation mechanisms. Hybridization could lead to loss of biodiversity (endangered species extinction in disturbed habitats due to anthropogenic and global environmental changes; rare, endangered species might be displaced by interspecific hybrids) or biodiversity enhancement (origin of new ecotypes, species). Results of genetic diversity of V. epipsila, V. palustris and hybrids with the use of ISSR markers and genome size evaluation from several Polish and European populations showed that ISSR and genome size value are good markers delimitating both species and hybrids. Selected qualitative and quantitative morphological traits along with embryological traits (pollen viability, set seeds) are good distinguishing characteristics of both species and hybrids. Results of genetic diversity of sympatric population from the Białowieża National Park evidently indicated the decreasing number of parental species and increasing number of hybrids caused by climate changes, lowering the water level, and the loss of alder forests and marshy meadows, habitats of both species. Loss of beat bogs reduce biodiversity of species occurring on these sites. Viola epipsila is endangered in Poland and other European countries. I am looking to hearing from you.

What about the crops health risks from environmental change and increase planting material in agricultural?
Please , I want your opinion. Thank you for your answer.
Hello, I am looking for articles: based age or gender- impacts of climate change and natural resource exploitation on Indigenous people? if do you know something I will be available to read your suggestions.
Thank you so much.
Long Term Ecological Research (LTER) sites are an important component of environmental change research and generate unique datasets. However, in many countries (e.g. Brazil) each site uses different methodologies, generates different metrics and has distinct objectives. Moreover, there is very little replication, with LTER sites spread across biomes and ecosystems. In the absence of formal meta-analysis, which is practically unfeasible, is there a way to synthesize the results of these valuable and unique studies to guide policy and practice?
Consequent to some food-borne incidents in recent years, there have been significant increase in public health concern and decrease in consumer confidence. Despite significant advances in detection tools, regulations, monitoring and consumer education on food safety, reports of food borne illness outbreaks continue to increase. Within the supply chain which is increasingly becoming more complex in the globalized market, adulteration (unintentional or intentional) is the key food safety issue. Increase in imports of food/processed food items due to cost concerns, availability and consumer demand for diverse food products also provide chances for food contamination/adulteration. Regulatory bodies are comforting with major food safety issues including changes in our food production and supply, environmental changes leading to food contamination, new and emerging bacteria, toxins, and antibiotic resistance and consumer preferences and habits leading to increase in imported foods. At this juncture, what should be the effective strategies to address the emerging challenges to provide safe, healthy, nutritious and sustainable produced food to the world's population?
The concept of climax community and succession particularly in terrestrial or water ecosystems where perturbations occur are interesting phenomena. Related concepts such as keystone species are also very important. But do these concepts apply in the microbial world where environmental changes drastically shift population and community dynamics in a very short time frame?
I am seeking for extracting roles of social aspects including social capital in climate change adaptation.
In order to corroborate environmental changes between modern samples (living snails) and specimens from an excavation.
Seeking robust analysis on the above to show the different ways in which environmental change impacts differentially and disproportionately on some people vs others and some countries vs others.
I am asking this question in the context of evaluating solar beam irradiation on buildings at city scale.
I am wondering if those variations impact the amount of energy perceived by building, and therefor should be taken into account while evaluating how buildings are warmed up by the sun.
I'm wondering is it possible to determine thermophile plants by following urban heat islands? There is an argue about Hordeum murinum L. is thermophilous. This idea based on occurrence of this species on urban heat islands in urban areas. Is this reasonable enough or should there be something else?
I also wonder if there is any specific studies about this topic?
I understand that, generally, community stability is defined by having no apparent change in population size over a given period of time. Such that, the level of disturbance occurring in a particular community is just one factor that greatly affects the stability of a community. So what are other significant factors which specifically affect the stability of a marine community, and how are these factors measured or quantified (if possible)?
While I've heard of some instances such as the environment recovering from oil spills, have people's efforts actually worked on facilitating the return to a healthy environment it once was? If there have been, are there any specific instances or situations where this actually occurred?
Human activity heavily disrupts community resilience. Other than that, is community resilience heavily reliant on the producers, consumers, keystone species, or something else entirely? How so?
I need to conduct a quantitative meta-analysis on the effect of anthropogenic factors on the evolution of animals. This is a very broad topic and I can only think of subjectively measuring the "fitness" of species affected by human activity such as pollution, habitat fragmentation, poaching, climate change etc.
Are there any other ways one could measure and compare the evolution of species in response to these anthropogenic challenges?
I interested in ' Integration climate change risk into river basin planning through applying SEA method in to planning process. How do you think about this?
I am undertaking a remote sensing analysis to distinguish areas of recent mangrove loss globally, and particularly in the Asia-Pacific region.
To help me on my way, I would like to understand which geospatial datasets are already in existence. I am looking for global mangrove datasets that are as up-to-date as possible, and across a broad timeframe from which I can undertake mangrove change analysis.
If you have datasets or ideas that could assist it would be great to hear from you. Many thanks!
The question is related to my research about the emergence and dynamics of 'green' markets in Brazil. I tend to deal with it in a 'idealist/culturalist' fashion, assuming changes that progressive changes in values, morals and in social institutions, more broadly, somehow implicate in changes in social practices. In my view, this implicated in contentious processes, though which shifts in practices are gradually enhanced and that may generate situations of major societal crises.
I'm conducting a research which its aim is to identify the relationship between environmental change and urbanization in a metropolitan area. For doing this, I'm using Landsat imagery data during the years 1990, 2000,2010 and 2016.
however, I classified all images in 3 classes with emphasizing the urban area by utilizing Neural Net algorithm in ENVI.
then I analyzed NDVI, LST and built-up index for all images.
Now how can I draw a conclusion for my primary objective? What is the best procedure for identifying the relationship between these indices?
I am compiling a series of historical case studies of transformative adaptation to major environmental changes, such as dryland salinity brought about by land clearing and changes in water availability due to high irrigation diversions and so on. I am keen to learn of examples that provide a perspective on social processes and decision making in relation to adaptive responses by people, particularly that relate to changes in societal values relating to the environment, how knowledge was used to scope choices for adaptation and how rules (legislation, policies, behaviours and norms) either enabled or constrained those choices. Any pointers to relevant literature would be gratefully received.
I'm trying to fit a dispersal kernel using CMR data from small mammals, to parameterize a Cellular Automaton (CA) designed to model range shifts driven by environmental change. This CA have annual steps, so I need a dispersal kernel standarized to 1 year dispersal events. Does anybody knows how to fit such dispersal kernel using data of dispersal events experienced in just a couple days (no more than one month)?
if someone can share a R script, it would be great,
Thank you so much!
In the personality literature there is increasing evidence on how different individuals can respond in a different (and consistent) way to changes in an environmental variable (e.g. temperature).
I was wondering if there is any evidence of the effect of personality (being bolder or shier, for instance) in how individuals can cope with environmental change. This is, are bolder individuals more resilient to temperature changes for instance? Does it give them any advantage? I need reports from wild animals, under natural conditions.
Urbanization is the process to by which large numbers of people become permanently concentrated in relatively small areas, forming cities and leading to population growth, economic growth and urban spatial expansion. Moreover, urbanization is considered to be the most important driver to make environmental change. Thus, the question is that "how can we measure the relationship between urbanization and environmental change?"
I want to study the environmental change of a coastal bay through sediment records, is there any appropriate proxies to quantitatively distinguish the human and natural caused marine environmental change?
I read that contingent valuation surveys can only provide estimates of WTP for discrete environmental changes. Conversely, choice experiments can be used to infer marginal WTPs. Is that generally true?
I am interesting to Know which instruments have focus in the aboriginal resilience, taking account the environmental changes. how the aboriginal communities assume the challenges of climate change.
I will be grateful with your suggestions!!!
It could be for any region, although my current interest is Brazil, but I am unsure if the spatial resolution available would be adequate. Thanks!
do i refer to a certification body to enable environmental change happen ? is this the only way or it depends also from agrarian reform from conventional wisdom to sustainable pathways,( a think that stays difficult in any country in transition)
A recent study concluded that any driver of environmental change that will cause a loss of plant diversity will in turn reduce the stable production of plant biomass through time.
.Hi All, I am planning to research on population dynamics, environmental change and human health nexus in developing countries. I have reviewed some models and would like more recommended materials and advise to polish up my proposal. Warm regards.
We have identified changes in microclimatic conditions of the storage dam construction area and its zone of influence. We have also suggest possible mitigation measures for possible changes in the area however the impacts may be cumulative or unavoidable. So if there is some related studies related to the topic I will be grateful for support and explore the research platform for further solution with broader discussion.
Using a quasi-experimental design, which of types signifies the best approach
I'm particularly interested in examples where plant species diversity has remained the same but the mix of species has altered considerably. Examples of peer reviewed papers or grey literature would be most appreciated.
If one has satellite images for a certain area on different times, is there any software for the analysis of these images in order to detect the environmental changes over a certain period?
according to resource based view, resources is the source of creating competitive advantage then what about ecosystem(environmental changes).
I am using an individual based stochastic model to explore the impact of environmental changes on speciation. In this model individuals forage in two different habitats with a probability determined by the profitability of the habitat. Apart from the ecological and mating loci, I have a certain number of non-coding neutral loci that are used to follow genetic signatures of evolutionary divergence. The neutral loci act like microsatellites, with high maturation rates. My question is how to calculate Fst in Matlab? Are there any softwares that can be used in Matlab not in R?
These wetlands are small in such a way that are not visible on landsat TM imagery. What other method can be applied for monitoring groundwater dependent ecosystems (springs,seeps and wetlands) using GIS and remote sensing? I don't want to use the Thompson et al.,(2002) method of identifying wetlands by combining aerial photography, GIS and remote sensing.
The main challenge is to learn how to deal with very dynamic systems in order to understand the effects of environmental changes and human pressures vs. natural dynamics...which methods and approaches can provide better answers?
Most researchers pay attention on temperature and CO2 alternation during life evolution, I mean geological periods, like Paleozoic, Mesozoic and Cenozoic. Is there any authentic data expressing other environmental factors like light, water, and chemical atmosphere component druing the geological periods?
