Based the strength this signal we then developed random forest (RF) models trained data to impute previously unstudied using Phylogenetic Eigenvector Maps. quantified uncertainty by fitting RF model test residuals skew exponential power distributions accounting heteroscedasticity, demonstrating encouraging lack biases in dataset.

Abstract Plant ecological strategies are shaped by numerous functional traits and their trade‐offs. Trait network analysis enables testing hypotheses for the shifting of trait correlation architecture across communities differing in climate productivity. We built plant networks (PTNs) 118 species within six an aridity gradient, from forest to semi‐desert California Floristic Province, based on 34 leaf wood traits, representing hydraulic photosynthetic function, structure, economics size. developed association PTN parameters with ecosystem properties, theory adaptation low resource/stressful environments versus higher resource availability greater potential niche differentiation. Thus, we hypothesized that community PTNs, connectivity (i.e., degree intercorrelated) complexity number modules, integration among modules) would be lower adapted arid climates water availability, similarly trends expected phylogenetic diversity, richness Further, given vary strongly most centrally connected PTNs those least across‐species variation. Across more wetter climates, varied less interconnected complex, richness, but was independent diversity Within variation were interconnected. Synthesis .

ABSTRACT The scale and resolution of trait databases molecular phylogenies is increasing rapidly. These resources permit many open questions in comparative biology to be addressed with the right statistical tools. Multi‐response (MR) phylogenetic mixed models (PMMs) offer great potential for multivariate analyses evolution. While flexible powerful, these methods are not often employed by researchers ecology evolution, reflecting a specialised technical literature that creates barriers usage biologists. Here we present practical accessible guide MR‐PMMs. We begin review single‐response (SR) PMMs introduce key concepts outline limitations this approach characterising patterns coevolution. emphasise MR‐PMMs as preferable involving multiple species traits, due explicit decomposition covariances. discuss multilevel models, extensions non‐Gaussian response traits. highlight techniques causal inference using graphical well advanced topics including prior specification latent factor models. Using simulated data visual examples, interpretation, prediction, model validation. implement discussed example plant functional traits demonstrate general utility handling complex real‐world sets.

Abstract Plants synthesize a broad array of specialized chemical compounds that mediate their interactions with the surrounding environment. Some this diversity is functional and subject to natural selection, but factors underlying evolution at intraspecific level remain largely unknown.

Examining closely related species evolving in similar environments offers valuable insights into the mechanisms driving phylogenetic conservatism and evolutionary lability. This can elucidate intricate relationship between inheritance environmental factors. Nonetheless, precise genomic dynamics molecular underpinnings of this process remain enigmatic. study explores adaptation exhibited by two high-altitude frog species: Nanorana parkeri N. pleskei. We assembled a high-quality genome for Tibetan pleskei compared it to genomes their lowland relatives. Our findings reveal that these diverged approximately 16.6 million years ago, pointing possible ancestral colonization high-elevation habitats. Following colonization, significant adaptive evolution occurred both coding non-coding regions lineage. led notable phenotypic alterations, as evidenced reduced body size. Also, due purifying selection, most features persisted descendant species, indicating strong element conservatism. However, evolved novel adaptations exacerbated challenges Tibet Plateau, mainly hypoxia response. Furthermore, our analysis underscores critical role regulatory variations evolution.
