Greater addition of neurons to the olfactory bulb than to the cerebral cortex of eulipotyphlans but not rodents, afrotherians or primates

open access: yesFrontiers in Neuroanatomy, 2014
The olfactory bulb is an evolutionarily old structure that antedates the appearance of a six-layered mammalian cerebral cortex. As such, the neuronal scaling rules that apply to scaling the mass of the olfactory bulb as a function of its number of ...

A Four-Monoclonal Antibody Combination Potently Neutralizes Multiple Botulinum Neurotoxin Serotypes C and D

open access: yesToxins, 2021
Human botulism can be caused by botulinum neurotoxin (BoNT) serotypes A to G. Here, we present an antibody-based antitoxin composed of four human monoclonal antibodies (mAbs) against BoNT/C, BoNT/D, and their mosaic toxins. This work built on our success

Mosaic evolution, preadaptation, and the evolution of evolvability in apes [PDF]

open access: yesEvolution, 2019
Abstract A major goal in post-synthesis evolutionary biology has been to better understand how complex interactions between traits drive movement along and facilitate the formation of distinct evolutionary pathways.

Coordinated scaling of cortical and cerebellar numbers of neurons

open access: yesFrontiers in Neuroanatomy, 2010
While larger brains possess concertedly larger cerebral cortices and cerebella, the relative size of the cerebral cortex increases with brain size, but relative cerebellar size does not.

Unsupervised learning of cone spectral classes from natural images. [PDF]

open access: yesPLoS Computational Biology, 2014
The first step in the evolution of primate trichromatic color vision was the expression of a third cone class not present in ancestral mammals. This observation motivates a fundamental question about the evolution of any sensory system: how is it ...

Phylogeny and Genetic Divergence among Sorghum Mosaic Virus Isolates Infecting Sugarcane

open access: yesPlants, 2023
Sorghum mosaic virus (SrMV, the genus Potyvirus of the family Potyviridae) is a causal agent of common mosaic in sugarcane and poses a threat to the global sugar industry.

Genomic Epidemiology and Evolution of Scallion Mosaic Potyvirus From Asymptomatic Wild Japanese Garlic

open access: yesFrontiers in Microbiology, 2021
Scallion mosaic virus (ScaMV) belongs to the turnip mosaic virus phylogenetic group of potyvirus and is known to infect domestic scallion plants (Allium chinense) in China and wild Japanese garlic (Allium macrostemon Bunge) in Japan. Wild Japanese garlic

Delaying quantitative resistance to pesticides and antibiotics

open access: yesEvolutionary Applications, 2022
How can we best vary the application of pesticides and antibiotics to delay resistance evolution? Previous theoretical comparisons of deployment strategies have focused on qualitative resistance traits and have mostly assumed that resistance alleles are ...

Brain structure evolution in a basal vertebrate clade: evidence from phylogenetic comparative analysis of cichlid fishes

open access: yesBMC Evolutionary Biology, 2009
Background The vertebrate brain is composed of several interconnected, functionally distinct structures and much debate has surrounded the basic question of how these structures evolve.

A mosaic pattern characterizes the evolution of the avian brain [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2004
Diversity in vertebrate brain size and composition is thought to arise from either developmental constraints that cause coordinated changes between brain regions or a mosaic model, whereby changes in individual brain regions are independent of changes in other brain regions.
