Historical Demography - Science topic

I'm using COI sequences for genetic populations and historical demography studies of the hard tick Rhipicephalus appendiculatus. I would like to estimate the time of demographic expansions and divergence time between two lineages of this tick described in Africa, but I need the mutation rate of the COI marker.

Dear collegues,

I am looking for a already prepared dataset of Model Life Table "West". Excel or Calc would be preferred. Thanks in advance!

Hi everyone I am new user of BEAST2 software. I worked on population genetics, phylogeny and phylogeography of a complex species in Caryophyllaceae family. I identified haplotypes in cpDNA and nDNA and have phylogeny trees based on haplotypes. Now I want estimate historical demography and divergence time but I cant calibrate it. There isn’t a fossil data or substitution rate. Only before the age of main clade of genus estimated 11 million years. In a similar papers I read “Posterior estimates of the mutation Rate and time of divergence were obtained by Markov Chain Monte Carlo(MCMC)analysis.” Any guidance appreciated Masi

im currently exploring institutional diets in the 18th century, comparing the daily calories consumed and need to compare these to modern daily estimates which would be enough to sustain a days work/labour or enough to have a healthy child...? 

I am looking for carpentries of OAK wood

I'm looking for any data on Population Statistics or Modelling for the past periods to compare them with our  results extracted from Wikipedia biographical pages (see attached links).

Hi everybody,

I am searching a paper (if any) reporting the rate of nucleotidic substitution of mitochondrial gene COI for Pinctada species (Mollusca, Bivalvia, Pteroidea). In case it does not exist, a value for closely related molluscs would be ok. I checked the literature for bivalve molluscs and I found a very high degree of heterogeneity across substitution rates.

Ciao

The common or garden, or simple assumption about the relationship between population size and resource consumption states that there is a direct relationship between the two. Clearly this assumption misses the point as to who is doing the consuming, when comparing those in developed and less developed regions. But I am wondering if the reverse assumption also holds, that population losses would lead to consumption falls, and whether this has been researched anywhere.

Most analysis relates to the effects of poor nutrition and not to energy deficit, even with normal nutrition, but below energy requirements. I intend to apply this to estimates of mortality under slavery.
