Is it possible to assess Nc in bumblebees and/or bees if the number of nest is known?

[Alicia Mastretta]

Hi,

We have a large project on Polinators at CONABIO, so we would like to include a native bumblebee or a native bee (NOT Apies melifera) in the assessment of genetic diversity indicators. There are some monitoring projects looking at the number of nests, with the aid of local farmers who are interested in their conservation as well as citizen scientists. There are also pop genetics and phylogeographic studies and the population definition is clear.

Question is, do you think we could use the number of nests and the (known) number of virgin females and males produced by nest to estimate Nc and then Ne? I'm not an insect person and my colleagues are not geneticists,  so any help or point to the right literature would be welcomed.

Thanks,

Alicia

Hi Alicia - one of our team members is also working on invertebrates and would like to discuss these kinds of challenges - could I send your email address to her? Thanks Catherine.

yes, of course.

Hi,

I'm working on a project to estimate distribution ranges and climate change effects on bumblebee species based on citizen science, and interested in this topic, though no genetics person in the project.

These are the literature related to Ne estimates for haplodiploid bee species.
Basically, the literature without using molecular markers estimates Ne as 1.5 times the number of queens (nests) assuming monogamy.
I think estimating Nc has little meaning for eusocial haplodiploid bees to evaluate genetic diversity.

Ellis, J.S., Knight, E., Darvill, B., Goulson, D. (2006). Extremely low effective population sizes,
genetic structuring and reduced genetic diversity in a threatened bumblebee species, Bombus
sylvarum (Hymenoptera: Apidae). Molecular Ecology, 15: 4375–4386
Charman, T.G., Sears, J., Green, R. E., Bourke, A. F. G. (2010). Conservation genetics, foraging
distance and nest density of the scarce Great Yellow Bumblebee (Bombus distinguendus).
Molecular Ecology, 19: 2661–2674.
Nomura, T., Takahashi, J. (2012). Effective population size in eusocial Hymenoptera with workerproduced males. Heredity, 109: 261–268.
Darvill, B., Knight, M.E., Goulson, D. (2004). Use of genetic markers to quantify bumblebee
foraging range and nest density. OIKOS, 107: 471–478
Nagamitsu, T,, Yamagishi, H. (2009). Nest density, genetic structure, and triploid workers in
exotic Bombus terrestris populations colonized Japan. Apidologie, 40: 429–440.

I know Dr. Nagamitsu well, the author of the last literature, and can ask him questions if needed.


Hope this information is helpful.

Best,

Fumiko

This is also a good issue for Dr. Frankham who has written about bees and Ne.

[Jessica da Silva]

I think many would be interested. Could a discussion be organized?
