Abstract

Human motor behavior is remarkably accurate and appropriate even though the properties of our own bodies as well as the objects we interact with vary over time. To adjust appropriately, the motor system has to estimate the context, that is the properties of objects in the world and the prevailing environmental conditions. Here we show that to determine the current context the CNS uses information from both prior knowledge of how the context might evolve over time and from the comparison of predicted and actual sensory feedback. We show that these two sources of information may be modeled within the CNS and combined to derive an accurate estimate of the context which adjusts motor command selection. This provides a novel probabilistic framework for sensorimotor control.

Genome sequencing and population genetics provide insights into local adaptation of Opisthopappus species on cliff environments of Taihang Mountains.

Local adaptation represents a pivotal theme in evolutionary biology. The Opisthopappus genus, comprising Opisthopappus longilobus and O. taihangensis, thrives on the cliffs of the Taihang Mountains. During their evolutionary history, two species are hypothesized to have locally adapted to their cliff habitats. In the present study, we employed a combined approach of whole-genome sequencing of O. taihangensis and population genomic analysis from both species to gain deeper insights into their patterns of local adaptation. Our results revealed that the expansive genome of O. taihangensis (3010.18 Mb), a consequence of a whole-genome duplication (WGD) event, coupled with a high proportion of repetitive sequences (82.70%), was postulated as one of its adaptive strategies. A clear differentiation between O. taihangensis and O. longilobus was observed, with the two species diverging approximately 17.57 million years ago (Mya), with O. longilobus serving as the ancestor. Since their divergence, limited gene flow was observed between the two species. Post-divergence, the effective population sizes of both species expanded, yet underwent a dramatic reduction at approximately 0.07 Mya. Furthermore, a total of 798 adaptive genes were identified, of which 207 overlapped with expanded genes, and eight genes were found to be under positive selection. These genes primarily regulated the growth and development of both species via pathways such as oxidation-reduction and ubiquitin-proteasome, enabling them to withstand climate changes. These findings provide profound insights into the local adaptation of Opisthopappus species to the cliff environments and offer valuable clues for further exploring the local adaptation among various cliff-dwelling organisms.

Variation in Drosophila melanogaster central metabolic genes appears driven by natural selection both within and between populations.

In this report, we examine the hypothesis that the drivers of latitudinal selection observed in the eastern US Drosophila melanogaster populations are reiterated within seasons in a temperate orchard population in Pennsylvania, USA. Specifically, we ask whether alleles that are apparently favoured in northern populations are also favoured early in the spring, and decrease in frequency from the spring to autumn with the population expansion. We use SNP data collected for 46 metabolic genes and 128 SNPs representing the central metabolic pathway and examine for the aggregate SNP allele frequencies whether the association of allele change with latitude and that with increasing days of spring-autumn season are reversed. Testing by random permutation, we observe a highly significant negative correlation between these associations that is consistent with this expectation. This correlation is stronger when we confine our analysis to only those alleles that show significant latitudinal changes. This pattern is not caused by association with chromosomal inversions. When data are resampled using SNPs for amino acid change the relationship is not significant but is supported when SNPs associated with cis-expression are only considered. Our results suggest that climate factors driving latitudinal molecular variation in a metabolic pathway are related to those operating on a seasonal level within populations.

Stimulation of defense factors for oysters deployed to contaminated sites in Pensacola Bay, Florida.

A positive association between chemical contaminants and defense factors has been established for eastern oysters (Crassostrea virginica) from Florida, but it is unknown whether such factors can be stimulated through short-term exposure to contaminants in the field. Hatchery oysters were deployed at two contaminated sites and one reference site near Pensacola, Florida, during spring and summer in 1998. Putative defense measurements, notably hemocyte count and bactericidal activity, were significantly elevated after 12-week deployment during summer at the most contaminated site. This site exhibited a dramatic increase in chemical concentrations in oyster tissue relative to both the initial concentrations in hatchery oysters and to oysters deployed at the reference site. Hemocyte activity was not stimulated after 16-week deployment of hatchery oysters in spring, despite similar increases in tissue chemical concentrations, so defense activation by short-term exposure may covary with other unmeasured environmental or physiological parameters. Using the converse approach, Pensacola Bay oysters were collected from two contaminated sites and deployed at the reference site for 16 weeks during spring. Results from this converse deployment were ambiguous; serum lysozyme concentrations were reduced for oysters transplanted from both sites, but hemocyte activities were not significantly changed. The principal outcome from this study was the demonstration of enhanced defense activities for oysters upon short-term summer deployment at a contaminated site.
