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,...
Abstract Publication bias threatens the validity of quantitative evidence from meta‐analyses as it results in some findings being overrepresented meta‐analytic datasets because they are published more frequently or sooner (e.g. ‘positive’ results). Unfortunately, methods to test for presence publication bias, assess its impact on results, unsuitable with high heterogeneity and non‐independence, is common ecology evolutionary biology. We first review both classic emerging tests funnel plots,...
Abstract Meta‐analysis is an important tool for synthesizing research on a variety of topics in ecology and evolution, including molecular ecology, but can be susceptible to nonindependence. Nonindependence affect two major interrelated components meta‐analysis: (i) the calculation effect size statistics (ii) estimation overall meta‐analytic estimates their uncertainty. While some solutions nonindependence exist at statistical analysis stages, there little advice what do when complex...
"Classic" forest plots show the effect sizes from individual studies and aggregate a meta-analysis. However, in ecology evolution, meta-analyses routinely contain over 100 sizes, making classic plot of limited use. We surveyed 102 finding that only 11% use plot. Instead, most used "forest-like plot," showing point estimates (with 95% confidence intervals [CIs]) series subgroups or categories meta-regression. propose modification forest-like plot, which we name "orchard plot." Orchard plots,...
Abstract Although meta‐analysis has become an essential tool in ecology and evolution, reporting of meta‐analytic results can still be much improved. To aid this, we have introduced the orchard plot, which presents not only overall estimates their confidence intervals, but also shows corresponding heterogeneity (as prediction intervals) individual effect sizes. Here, added significant enhancements by integrating many new functionalities into orchaRd 2.0 . This updated version allows...
Abstract Exposure to extreme temperatures can negatively affect animal reproduction, by disrupting the ability of individuals produce any offspring (fertility), or number produced fertile (fecundity). This has important ecological consequences, because reproduction is ultimate measure population fitness: a reduction in reproductive output lowers growth rate and increases extinction risk. Despite this importance, there have been no large‐scale summaries evidence for effect temperature on...
Despite the importance of identifying predictable regularities for knowledge transfer across contexts, generality ecological and evolutionary findings is yet to be systematically quantified. We present first large-scale evaluation using new metrics. By focusing on biologically relevant study levels, we show that generalization not uncommon. Overall, 20% meta-analyses will produce a non-zero effect 95% time in future replication studies with 70% probability observing meaningful effects...
To persist, unisexual and asexual eukaryotes must have reproductive modes that circumvent normal bisexual reproduction. Parthenogenesis, gynogenesis, hybridogenesis are the generally been ascribed to various unisexuals. Unisexual Ambystoma abundant around Great Lakes region of North America, variously described as having all 3 modes. Diploid polyploid unisexuals nuclear genomes combine haploid 2 4 distinct sexual species, but mtDNA is unlike any those species similar another barbouri ....
Abstract Research synthesis, such as comparative and meta‐analyses, requires the extraction of effect sizes from primary literature, which are commonly calculated descriptive statistics. However, exact values statistics hidden in figures. Extracting figures can be a slow process that is not easily reproducible. Additionally, current software lacks an ability to incorporate important metadata (e.g. sample sizes, treatment/variable names) about experiments integrated with other streamline...
OBJECTIVE The generation of mature cell types during pancreatic development depends on the expression many regulatory and signaling proteins. In this study, we tested hypothesis that transcriptional regulator Islet-1 (Isl-1), whose is first detected in mesenchyme epithelium developing pancreas later restricted to islet cells, involved terminal differentiation cells maintenance mass. RESEARCH DESIGN AND METHODS To investigate role Isl-1 secondary transition, was conditionally specifically...
Understanding individual differences in cognitive performance is a major challenge to animal behaviour and cognition studies. We used the Eastern water skink (Eulamprus quoyii) examine associations between exploration, boldness variability spatial learning, dimension of lizard with important bearing on fitness. show that males perform better than females biologically relevant learning task. This first evidence for sex reptile, we argue it probably owing sex-specific selective pressures may...
Rapid environmental change is predicted to compromise population survival, and the resulting strong selective pressure can erode genetic variation, making evolutionary rescue unlikely. Non-genetic inheritance may provide a solution this problem help explain current lack of fit between purely models empirical data. We hypothesize that epigenetic modifications facilitate through 'epigenetic buffering'. By facilitating novel phenotypic variants are generated by change-a strategy we call...
Environmentally induced phenotypes have been proposed to initiate and bias adaptive evolutionary change toward particular directions. The potential for this happen depends in part on how well plastic responses are aligned with the additive genetic variance covariance traits. Using meta-analysis, we demonstrate that novel environments tend occur along phenotype dimensions harbor substantial amounts of variation. This suggests selection or against environmentally typically will be effective....
Phenotypic responses to a novel or extreme environment are initially plastic, only later be followed by genetic change. Whether not environmentally induced phenotypes sufficiently recurrent and fit leave signature in adaptive evolution is debated. Here, we analyze multivariate data from 34 plant reciprocal transplant studies test: (1) if plasticity an source of developmental bias that makes locally adapted populations resemble the ancestors; (2) plasticity, standing phenotypic variation...
Abstract A recent meta‐analysis concluded, ‘ transgenerational effects are widespread, strong and persistent’ . We identify biases in the literature search, data analyses, questioning that conclusion. Re‐analyses indicate few studies actually tested – making it challenging to disentangle condition‐transfer from anticipatory parental effects, providing little insight into underlying mechanisms.
