Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Accounting for molecular stochasticity in systematic revisions: species limits and phylogeny of Paroaria [PDF]
, 2009 Different frameworks have been proposed for using molecular data in systematic revisions, but there is ongoing debate on their applicability, merits and shortcomings.

Detecting cryptic ghost lineage introgression in four‐taxon genomic datasets
Applications in Plant Sciences, EarlyView.Abstract Premise Hybridization and introgression are pervasive evolutionary forces that have played fundamental roles in shaping the diversity of wild and domesticated plants. Four‐taxon tests for introgression provide a reliable framework for detecting signatures of ancient introgression from genomic data, which have played an important role in ...

Frontiers in Genetics, 2014 Many hypotheses have been put forth to explain the origin and spread of inversions, and their significance for speciation. Several recent genic models have proposed that inversions promote speciation with gene flow due to the adaptive significance of the

Speciation Progress: A Case Study on the Bushcricket Poecilimon veluchianus. [PDF]
PLoS ONE, 2015 Different mechanisms such as selection or genetic drift permitted e.g. by geographical isolation can lead to differentiation of populations and could cause subsequent speciation.

Diversity, 2022 Groups of recent speciation are characterized by high levels of introgression and gene flow, which often confounds delimitation of species on a DNA basis.

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Can preference for oviposition sites initiate reproductive isolation in Callosobruchus maculatus? [PDF]
PLoS ONE, 2011 Theory has identified a variety of evolutionary processes that may lead to speciation. Our study includes selection experiments using different host plants and test key predictions concerning models of speciation based on host plant choice, such as the ...

Reinforcement Can Overcome Gene Flow during Speciation in Drosophila [PDF]
Current Biology, 2010 Reinforcement, the strengthening of prezygotic reproductive isolation by natural selection in response to maladaptive hybridization [1-3], is one of the few processes in which natural selection directly favors the evolution of species as discrete groups (e.g., [4-7]).

The Anatomical Record, EarlyView.Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...
