A protocol for data exploration to avoid common statistical problems
TL;DR: A protocol for data exploration is provided; current tools to detect outliers, heterogeneity of variance, collinearity, dependence of observations, problems with interactions, double zeros in multivariate analysis, zero inflation in generalized linear modelling, and the correct type of relationships between dependent and independent variables are discussed; and advice on how to address these problems when they arise is provided.

Habitat fragmentation causes immediate and time‐delayed biodiversity loss at different trophic levels
Jochen Krauss,Riccardo Bommarco,Moisès Guardiola,Risto K. Heikkinen,Aveliina Helm,Mikko Kuussaari,Regina Lindborg,Erik Öckinger,Meelis Pärtel,Joan Pino,Juha Pöyry,Katja M. Raatikainen,Anu Sang,Constantí Stefanescu,Tiit Teder,Martin Zobel,Ingolf Steffan-Dewenter +16 more
TL;DR: Present-day species richness of long-lived vascular plant specialists was better explained by past than current landscape patterns, indicating an extinction debt, while short-lived butterfly specialists showed no evidence for an extinction Debt at a time scale of c.

Do not log-transform count data
Robert B. O'Hara,D. Johan Kotze +1 more
TL;DR: This work compared the outcome of fitting models that were transformed in various ways with results from fitting models using Poisson and negative binomial models to untransformed count data, finding that the transformations performed poorly, except when the dispersion was small and the mean counts were large.

Egg size and offspring quality: a meta-analysis in birds.
TL;DR: Positive effect sizes found in this study are likely to be driven by a causal effect of egg size on offspring quality, but more studies that control for potential confounding effects of parental post‐hatching care, genes, and egg composition are needed to establish firmly this causal link.
Journal ArticleDOI
The GRoLTS-Checklist: Guidelines for Reporting on Latent Trajectory Studies
TL;DR: The purpose of GRoLTS is to present criteria that should be included when reporting the results of latent trajectory analysis across research fields, and goes through a systematic process to identify key components that, according to a panel of experts, are necessary when reporting results for trajectory studies.

The Effects of Natural and Anthropogenic Microparticles on Individual Fitness in Daphnia magna.
TL;DR: It is suggested that MPs and, in particular, SMPs have a greater capacity to negatively affect feeding in D. magna compared to naturally occurring mineral particles of similar size.
