Meta-analysis provides formal statistical techniques for summarizing the results of independent experiments and is increasingly being used in ecology. The response ratio (the mean outcome experimental group to that control group) closely related measures proportionate change are often as effect magnitude Using these metrics meta-analysis requires knowledge their properties, but have not been previously derived. We give approximate sampling distribution log ratio, discuss why it a...
Invasion biologists often suggest that phenotypic plasticity plays an important role in successful plant invasions. Assuming enhances ecological niche breadth and therefore confers a fitness advantage, recent studies have posed two main hypotheses: (1) invasive species are more plastic than non-invasive or native ones; (2) populations the introduced range of evolved greater range. These hypotheses largely reflect disparate interests ecologists evolutionary biologists. Because these sciences...
Meta-analysis is the use of statistical methods to summarize research findings across studies. Special are usually needed for meta-analysis, both because effect-size indexes typically highly heteroscedastic and it desirable be able distinguish between-study variance from within-study sampling-error variance. We outline a number considerations related choosing meta-analysis ecological data, including choice parametric vs. resampling methods, reasons conducting weighted analyses where...
A meta-analysis was conducted on field-competition experiments published in six journals over a 10-yr period. We analyzed the effects of competition biomass organisms belonging to 93 species wide variety habitats. Competition had large effect overall, with great deal heterogeneity that among organisms. There were differences trophic levels competitive effects, but relative magnitude at different contrary predictions ecological theory. Primary producers and carnivores displayed small medium...
The International Tundra Experiment (ITEX) is a collaborative, multisite experiment using common temperature manipulation to examine variability in species response across climatic and geographic gradients of tundra ecosystems. ITEX was designed specifically arctic alpine increased temperature. We compiled from one four years experimental data 13 different sites used meta-analysis analyze responses plant phenology, growth, reproduction warming. Results indicate that key phenological events...
raise global mean temperature over the next century by 1.0–3.5 °C (Houghton et al. 1995, 1996). Ecologists from around world have begun experiments to investigate effects of warming on terrestrial ecosystems, aspect climate change that attracts most public attention (Woodwell and McKenzie Walker Steffen 1999). The effort understand response builds a history investigations elevated CO 2 plants ecosystems (Koch Mooney 1996, Schulze There are important differences, however, between increases in...
In ecological field surveys, observations are gathered at different spatial locations. The purpose may be to relate biological response variables (e.g., species abundances) explanatory environmental soil characteristics). the absence of prior knowledge, ecologists have been taught rely on systematic or random sampling designs. If there is knowledge about patterning variables, obtained from either previous surveys a pilot study, can we use this information optimize design in order maximize...
Meta-analysis is a statistical technique that allows one to combine the results from multiple studies glean inferences on overall importance of various phenomena. This method can prove be more informative than common "vote counting," in which number significant compared with nonsignificant determine whether phenomenon interest globally important. While use meta-analysis widespread medicine and social sciences, only recently has it been applied ecological questions. We parametric confidence...
Climate models project that by 2100, the northeastern US and eastern Canada will warm approximately 3–5 °C, with increased winter precipitation. These changes affect trees directly also indirectly through effects on “nuisance” species, such as insect pests, pathogens, invasive plants. We review how basic ecological principles can be used to predict nuisance species’ responses climate change this is likely impact forests. then examine in detail potential of two pest species (hemlock woolly...
Quantitative synthesis across studies requires consistent measures of effect size among studies. In community ecology, these will often be some measure the strength interactions between taxa. However, indices interaction vary greatly both theoretical and empirical studies, connection hypotheses about metrics that are used to test not explicit. We describe criteria for choosing appropriate methods comparing them at three stages designing a meta-analysis variation in intensity: (1) choice...
Ecologists working with a range of organisms and environments have carried out manipulative field experiments that enable us to ask questions about the interaction between competition predation (including herbivory) relative strength in field. Evaluated together, such collection studies can offer insight into importance function these factors nature. Using new factorial meta-analysis technique, we combined results 20 articles reporting on 39 published whether presence predators affects...
Summary The number of published meta‐analyses in plant ecology has increased greatly over the last two decades. Meta‐analysis made a significant contribution to field, allowing review evidence for various ecological hypotheses and theories, estimation effects major environmental drivers (climate change, habitat fragmentation, invasive species, air pollution), assessment management conservation strategies, comparison across different temporal spatial scales, taxa ecosystems, as well research...
Since the early 1990s, ecologists and evolutionary biologists have aggregated primary research using meta-analytic methods to understand ecological phenomena. Meta-analyses can resolve long-standing disputes, dispel spurious claims, generate new questions. At their worst, however, meta-analysis publications are wolves in sheep's clothing: subjective with biased conclusions, hidden under coats of objective authority. Conclusions be rendered unreliable by inappropriate statistical methods,...
Summary Meta‐analysis and meta‐regression are statistical methods for synthesizing modelling the results of different studies, critical research synthesis tools in ecology evolutionary biology (E&E). However, many E&E researchers carry out meta‐analyses using software that is limited its functionality not easily updatable. It likely these limitations have slowed uptake new scope quality inferences from syntheses. We developed OpenMEE: Open Meta‐analyst Ecology Evolution to address...
Species introductions of anthropogenic origins are a major aspect rapid ecological change globally. Research on biological invasions has generated large literature many different aspects this phenomenon. Here, we describe and categorize some literature, to better understand what been studied know, mapping well-studied areas important gaps. To do so, employ the techniques systematic reviewing widely adopted in other scientific disciplines, further use approaches that as scientific,...
