The evolutionary history of a set of taxa is usually represented by a phylogenetic tree, and this model has greatly facilitated the discussion and testing of hypotheses. However, it is well known that more complex evolut...

The use of evolutionary and swarm intelligence algorithms, has become a very popular option to solve complex real-world optimization problems. However, in their original versions, these algorithms lack a mechanism to han...

Gastropoda, with approximately 80,000 living species, is the largest class of Mollusca. Among gastropods, apple snails (family Ampullariidae) are globally distributed in tropical and subtropical freshwater ecosystems and...

ABSTRACT The Amazonian megadiversity remains understudied and underestimated due to the region’s vast size, environmental heterogeneity, and inaccessibility. With increasing threats to the biome, it is crucial to map c...

ABSTRACT Scorpion envenoming is considered a public health problem in Brazil. A recent study described a variation in the clinical outcome of envenoming by Tityus obscurus in two populations separated by 850 km in the no...

Ultra-massive white dwarfs are powerful tools used to study various physical processes in the asymptotic giant branch (AGB), type Ia supernova explosions, and the theory of crystallization through white dwarf asteroseism...

UNLABELLED: We have developed a new software package, Molecular Evolutionary Genetics Analysis version 2 (MEGA2), for exploring and analyzing aligned DNA or protein sequences from an evolutionary perspective. MEGA2 vastl...

Limblessness is a condition common among reptiles, but rare among endotherms. It provides an excellent working surface for evolutionary studies, as organismic diversity provides us with many interrnediate stages. These a...

LA-ICP-MS (Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry), PIXE (Particle Induced X-ray Emision), µ-XRD (Micro X-ray Diffraction) and SEM (Scanning Electron Microscope) techniques are combined in molecular...

Different studies have tried to find a common thread that places different evolutionary and neo-Schumpeterian contributions to economic change under one umbrella. The complexity approach can account for a set of attribut...

Abstract Industrial emissions are significant contributors to global air pollution, particularly with respect to PM2.5 and CO2 emissions. It remains one of the most pressing environmental challenges globally, driven larg...

Abstract Background Poly(A) tails play crucial roles in regulating mRNA degradation and translation, yet their evolutionary dynamics remain largely unexplored. Results Here, we generate a comprehensive full-length RNA at...

Paedotherium was the last representative of the pachyrukhines (Notoungulata, Hegetotheriidae), a small rabbit- or caviomorph rodent-like clade, with hypsodont and simplified dentition. In contrast to the Pliocene Paedoth...

Here, we present preliminary results from research investigating the influence of different pedagogical methods on skill acquisition amongst novice knappers, with implications for interpreting the Paleolithic and devisin...

Although variation in effect sizes and predicted values among studies of similar phenomena is inevitable, such variation far exceeds what might be produced by sampling error alone. One possible explanation for variation ...

Abstract Background Optimization of biotechnological processes is traditionally limited by time-consuming trial-and-error approaches and the complexity of simultaneously optimizing multiple, often conflicting objectives....
