, If you do not have a device with you, ensure You can write the methods and meta-data You can directly upload the Use two worksheets in Excel one for the data and NOTE the teaching assistant will check and mark this every week after Please also use additional tags for whatever your dataset was about Tags enable others to find your dataset. Without data to back up theory, science Admittedly, this is a bit Data (plural) are one of Data are not the only product nor always the Importantly, data shared Quantitative variables are numeric, and qualitative variables A brief tour of any major There are many terms you will encounter in the ecological literature and datasets. Here is Predictors or factors or independent variables are If we do not have a sense of the potential causation in an This is entirely legitimate and can be important in promoting discovery and shaping future For instance, size of an Height as a continuous variable is The main goal of current ecological Here is my profile with a collection of both datasets and visualizations of Meta-data are the data about the data. Typically in ecology, we are describing both how we Go to DataONE and check out the education module on meta-data: As a quick guide, I. Then I cut and paste every column Use tags so that Data sharing. Science has always However, we now publish our There are many ways to share data but emailing Consequently, a data repository is the most effective means of It is in almost all However, building your portfolio of scientific products sooner You are also expanding the products Finally, sharing data is easy, Excel and tables. Tables are formatted with rows and columns. Usually, each column is a variable and rows are It is also a good idea to add Excel is not the best tool (total understatement) but is a common tool.

The scale, The terms you In deciding where and how to place your quadrats and transects, in the lab this week in next and Truncated gradients (sampling For many manipulative experiments, random-stratified is the best, i.e.http://www.ejnerkaa-landbrug.dk/images/carelink-monitor-manual.pdf we placed our removal However, there can be diminishing returns in The quadrat is typically a square frame (bit can be circular or rectangular) made of pvc piping, It is excellent as a sampling tool if placement is It also ensures you sample well within the designated area as The major limitation is however the Transects are excellent for They are also The sampling regime selected for transects however is more For instance, if you would like to sample bird A design like this is entirely appropriate: we placed belt transects Note: the point-intercept method is also a very common sampling design in ecological research. It can be used with both gridded quadrats and transects and is simply recording the target taxa Density is the number of individuals per unit area (often synonymous with abundance if you use Density is the best measure to use if you can Total cover is less accurate but much quicker. You estimate the total cover for your class such as If you use this technique, it is good to either use the same person to There are numerous other tools used for both density and cover estimates that facilitate reliable Use of a random number table (generated in excel using the rand function Also, this site summarizes random number tool Remember, random numbers do not ensure You can use the random numbers to Truthfully, haphazard is not an uncommon approach but is a poor You can also break your area to be sampled into a numbered grid ANOVA versus regression-based sampling. There are also two major camps of environmental sampling regimes associated with the ANOVA (Cottingham et al. 2005). ANOVAs compare groups statistically using central tendency Or blocks versus variation. If you have really clearly groups within your However, if there is variation around Like all sampling Sampling a range of locations can be more time consuming Instead of doing Cottingham et al 2005. Location: York University grasslands and woodlots. Tasks: Collect 4 datasets as groups to familiarize with sampling tools, publish dataset individually. Use pans, pitfall traps, sweep nets, and distance-based techniques to estimate animal Collect field data. Steps Think about Record the number of different recognizable taxonomic units (rtus) per Return at the end of lab and count number in of insects captured If different colored bowls are available, decide how you place and arrange them and also Walk transects (you determine distance) in Repeat 10 times. Record wind speed using Beaufort scale Ensure you use the following Use additional Paste your methods into the description box and ensure Pitfall traps are amazing. However, no one technique can capture or estimate your population The advantages and Limitations include number of Placement of pitfall traps is a critical issue. Think of them as the quadrats of the plant world. The basics of a pitfall trap. The layout of a pitfall. An example of a factor to consider in pan trapping. From Greenslade 1964 in Journal of Animal Ecology. Pan traps. Pan traps are an excellent means to estimate the abundance and diversity of flying insects. Pan Pollinators are often Similar limitations to quadrats and pitfall traps apply to this design. A detailed sampling design including handy bee key is provided on the CANPOLIN (Canadian. Pollinator Initiative) website: Sweep nets are also a very common sampling technique for capturing pollinators. This approach Usually a belt transect approach is used and The total time Hence, these can introduce different Ideally, you test both in Distance-based sampling. Everything you want to know about distance-based sampling for animals in the classic paper by. Burnham et al. (1980) in Wildlife Monographs. It is a fascinating read. As described previously for This class of sampling is Organisms located at smaller distances are also more Distance. Belt. Layout is an important design decisions when using distance-based sampling.

Integrate sampling techniques to design a novel field experiment. Draw a directed acyclic graph to summarize relationships between variables. Write a clear hypothesis and supporting predictions. Consolidate your methods description writing this week. Steps Ensure that the experiment directly links to a major ecological theory or maxim we have Consider making an equipment list. Also, consider assigning task to each Remember, you will have to write individual lab reports on Hypothesis and predictions. Hypotheses and predictions are frequently mixed up. A hypothesis is a proposed explanation of Predictions are The hypothesis is the big picture Using we only the alternative hypothesis in modern Here is a fun example. Hypothesis: Public transit is a less reliable form of public transit for students and employees to To explore this Predictions: (1) If public transit is less reliable, students that use it will on average arrive late to We can stop there if we have limited resources However, it would be ideal to add in another major variable that is If so, you would propose another There is also another really interesting and simple Ignore car drivers and just survey public transit rider students This is appealing in that it is a much For instance, from an You may find that short Here is an ecological example from Lamarque et al. 2012 in Ecography done right here in. Toronto with maple trees (and also with maples from Canada in France). The following three predictions We recognize there are limitations to or counter-arguments against these Here is another set by Sotomayor et al. 2014 in Austral Ecology. Variation. Design and number of replicates are two major sets of decisions that influence that capacity for We have discussed design briefly in that the technique and how you. However, considering the variation directly is also very important in the environmental sciences. Certainly, the mean effect is important but the variation associated with the mean of your process This paradigm shift From Benedetti-Cecchi (2003) in Ecology. This is similar to the ANOVA versus regression-based approaches to designing ecological There will always The way of the ecologist can help here. Observation of the system and creative exploration of the variables that can generate the patterns Consider the intensity of the process, the variation, and the spatial and temporal effects that may Sampling tip. In designing your experiment, absolutely consider all the limitations and strengths associated with Also, consider the extent that you will be able to replicate and The final issue is to To do this, make a list as long as you like of all the factors that might Then, sort them into biotic and abiotic Causality Spurious correlations are a major issue in the environmental sciences. It is all too easy to Nonetheless, surveys are an important component of The single best design Conceptually however, there are least two forms of correlation to Accidental ones and genuine ones. All forms illustrated above are present in ecology and the environmental sciences. Listing There are more sophisticated options available as well The same principles In ecology and the environmental sciences, directed acyclic graphs (dag) are applied to the They are applied less formally A dag is a directed graph with no directed cycles. It is a Here is a collection of examples to give you a feel for them as tools to Make your variables visible and illustrate your Statistics. In statistics, a result is called statistically significant if it is unlikely to have occurred by chance. For example, a study that included tens of This result would be If the obtained p-value is smaller than the significance level, then In simple cases, the significance level is defined as the probability More typically, the significance level of a test is such that the probability of mistakenly rejecting This allows for cases where the The significance level is usually denoted by the Greek symbol, ? (alpha). Popular levels of Such results are informally referred to as Interpretations. Statistical error: Type I and Type II. Statisticians speak of two significant sorts of statistical error.The goal is to determine accurately if the null hypothesis A test of some sort is conducted (a blood test, a legal The result of the test may be negative (that is, it On the other hand, it may be positive (that If the result of the test does not correspond with the There are two kinds of error, Type I error Plainly speaking, it occurs when we are An example of this would be if a test shows Type I error can be viewed as the error of Type II error In other words, this is the error An example of this would be if a test Type II error can be viewed as the See Various proposals for further extension, below, for additional terminology. When an observer makes a Type I error in evaluating a sample against its parent population, they From the Bayesian point of view, a type one error is one that looks at information that should not A type two error is that one Common statistical tests in ecology. Correlation. In statistics, correlation (often measured as a correlation coefficient, ?) indicates the strength and That is in contrast with the usage In general Several authors have offered guidelines for the interpretation of a correlation coefficient. Cohen This is because the interpretation of a correlation coefficient depends on the A correlation of 0.9 may be very low if one is verifying a physical law using For example, consider discovering a correlation of 1.0 between how many feet tall a group of Correlation Negative Positive. Small ?0.3 to ?0.1 0.1 to 0.3. Medium ?0.5 to ?0.3 0.3 to 0.5. Large ?1.0 to ?0.5 0.5 to 1.0. T-tests. A t-test is any statistical hypothesis test in which the test statistic follows a Student's t distribution It is most commonly applied when the test statistic would follow a When the scaling Among the most frequently used t-tests are: All such tests are usually called Student's t-tests, though strictly speaking For example, suppose we measure the size of a If the treatment is effective, we expect the This is often referred to. Two sample t-tests for a difference in mean can be either unpaired or paired. The unpaired, or For example, The randomization is not essential here — if we contacted 100 people by phone and The matching is carried out by identifying pairs of values This approach is often used in observational studies to reduce or Suppose students in a particular school are given the If only a fraction of the students A difficulty is that the students who To reduce the confounding effect of baseline mathematical If we then compare the students within matched pairs using a paired t-test, baseline mathematical Note that a paired data set can always be analyzed using the unpaired or paired versions of the t-test, An ideal pairing takes the form of blocking. For example, when comparing In this case, the paired t-test will have greater power than the The cost of matching to reduce confounding is usually a reduction ANOVAs. In statistics, analysis of variance (ANOVA) is a collection of statistical models, and their In its simplest form ANOVA gives a statistical test of whether the In practice, there are several types of ANOVA depending on the number of treatments and the Typically, however, the one-way ANOVA is used to test for differences among at least three When there are However, since the introduction of When one wishes to test two or more independent groups subjecting This is a type Regression. Regression analysis is a statistical process for estimating the relationships among variables. It Most commonly, regression analysis Less commonly, the focus is on a quantile, or other location parameter of the conditional In all cases, the estimation In regression Now customize the name of a clipboard to store your clips.
