- Matt Falcy added an answer:1The Zippin Method: Calculating 1-q^k without graph?
I've been using Zippin's method of calculating estimate of population size (calculating R based on k trappings and using the graph to find 1-q^k) I just was wondering how you can calculate 1-q^k without using the included graphs in his article. There must be a way of calculating it if he created the graph. I'm asking because I want to create a formula in Excel to calculate it automatically using R; but I don't know how.

- A. Panis added an answer:4Is there a sensu stricto leaf-litter ant fauna in temperate forest?
One of the reviewers of my new paper on forest ant communities in western Carpathians (Central Europe) stated, that there is not a litter ant fauna in the temperate zone forest. That was something I did not expect to hear, regarding a number of species that can be found in European forest leaf-litter layer including Stenamma debile, Temnothorax crassispinus, T. parvulus, Myrmecina graminicola, which I always considerd to be litter species. Then I started to realize, that they really dont have to be strict litter dwellers, and might simply belong to epi- or even hypogeic species. I would really appreciate to see some more opinions on this topic.
In dry oak woods of Var (Quercus pubesccens associated with Quercus ilicis plus typical Mediterranean bushes but without Myrtus communis, and on the soil only the herb Brachypodium phoenicoides) of South-Eastern France, under the intermediate climate named hill Mediterranean (altitudes 400-800 m), leaf litter is more or less thick. Into litter and under litter are at least 3 ant species (workers). Sometimes I (email@example.com, André Panis) discover nest of a very small yellowish to light brown ant species (with soldiers, workers, queen) at the interface between litter and soil.I have one book for identification of ants living in France. Unfortunately, I had not till to-day enough time for identification of these ant-species. Sincerely yours.Following
- Maria Fremlin added an answer:9Can anyone supply live specimens of female Dorcus parallelipipedus?
I am collaborating with Masahiko Tanahashi on a comparative study of their mycangium xylose-fermenting yeasts. Presently, we need specimens across their range; except for the UK and Switzerland. Specimens from Spain are top priority; this is to solve the riddle of the origin of the famous Pichia stipitis yeast CBS 6054. For more see: The mystery of the lesser stag beetle Dorcus parallelipipedus (L.) (Coleoptera: Lucanidae) mycangium yeasts. Bulletin of the Amateur Entomologists' Society, 72 (510): 146-152.
Thanks Francesco and Alessandro for your interest.
Well, here is what Masahiko recommends:
""Regarding the packaging, I usually put an insect in a small
plastic container (like a Tupperware or some medicine container),
pack tissue paper so tightly that insect cannot move, and add
water to moisten the tissue paper. One or more air vent hole(s)
should be needed, depending on the size and air-tightness of
the container. It would be better to tape the lid of the container.
The insects can survive at least two weeks at moderate temperature
if only there is sufficient moisture. On this point, a little
largish container, compared to the insect itself, may be better
for a long journey from Europe to Japan. Never include a food
material within a package because it will be fermented during
transport and cause severe oxygen deficiency. If you have two or
more D.parallelipipedus females that were collected at the same
sampling site, putting multiple insects in a larger container is
not a problem."
I have sent him stag beetles from the UK. It is perfectly legal here; but the rules might be different across European countries. The journey takes about one week by air. Once I sent a female Dp inside as media card; very tight but she survived. An old CD box would be far superior accommodation, though.
In any case, I shall give updates if any beetles have been sent and which countries. Spain and France are top priority!
- Simon Carpenter added an answer:4What statistical analysis should I use for measuring dispersal of insect vectors using mark–release–recapture techniques?
I intend to study the dispersal pattern of phlebotomine sand flies in a forested area in the cerrado (savanna) biome of Northeastern Brazil. Human dwellings and domestic animals are commonly found in the area. What is the best statistical test that should be applied in the analysis? The insects will be trapped, marked with fluorescent dust and then released at different collecting points. I will try to recapture the phlebotomine sand flies in the next ten days. I want to gather information about dispersal range, spatial memory, host fidelity, site fidelity and longevity. Can you help me?

- Riaan F Rifkin added an answer:2Is there any conclusive genetic or archaeological evidence for the geographic origin and subsequent distribution of Pulex irritans?
The human flea, Pulex irritans, is a cosmopolitan flea species that has, in spite of the common name, a wide host spectrum. It is one of six species in the genus Pulex; the other five are all confined to the Nearctic and Neotropical regions. The species is thought to have originated in South America, where its original host may have been the guinea pig or peccary.
Thank you very much Paulo! I have recently come across Ctenocephalides felis remains in African MSA contexts, hence my question about P. irritans which, evidently were in all probability not present in Southern Africa before about 2000 years ago when Bantu-speaking agro-pastoralists entered the region. I am still looking for details concerning the precise route of spread into Africa though.Following
- Ana-Maria Ciobotaru added an answer:4Can anyone suggest peer-reviewed articles(s) noting the spread of Osmia taurus in Eastern US - especially as it relates to its southerly migration?
Since the unintentional Nearctic introduction of O. taurus to the Mid-Atlantic in the 1970's, the species has been spreading - colonizing & naturalizing as it goes. While mostly recorded spreading due-West & North-East along the coast from its original landfall to date, Georgia now marks the most southerly progression of the species. Both its adaptability to the environs of the Eastern US, as well as its remarkable population growth once present, should be of note for both researchers and farmers.
To track the progression of Osmia taurus into the Deep South, I would really appreciate any peer-reviewed literature which identified O. taurus outside its suspected original Mid-Atlantic port-of-call - most importantly South of the Mason-Dixon (anywhere from MD through WV, VA, KY, TN, SC, NC...).
** Also, any papers like those requested above - but pertaining to the presence of Osmia cornifrons & Anthidium manicatum - would likewise be very much appreciated!! **

Both specimens were found dead in forest islets and with almost five years apart when found them. I also attached two pictures in case this might be a case of wrong identification.
I have contacted a researcher specialist about this issue, and has very kindly helped me.

- Steve W Wilson added an answer:8Do you have any experiences on the spread and damage of Metcalfa pruinosa (Flatidae) in your country?Citrus flatid planthopper, a native insect to North America, have had for a long time a scarce economic importance there. However, being polyphagous made small damage on citrus trees and some ornamentals. In 1979 it was introduced to Italy where it established and spread quickly. It is now an invasive alien species (IAS) continually spreading in South and Central Europe causing considerable damage in grapevine, fruit trees and various ornamentals.
In Hungary M. pruinosa causes damage - as in other European countries - in grapevine, fruit and other ornamental trees and shrubs. Unfortunately, it spreads in semi-natural and natural areas like hedges. I have observed nymphs, adults and vaxy filaments of M. pruinosa on the majority (70%) of the trees and shrubs in a hedge.
Infested plants – among them some with American origin – were: Acer negundo, Celtis occidentalis, Clematis vitalba, Crataegus monogyna, Hedera helix, Juglans regia, Lycium barbarus, Malus domestica, Morus alba, Prunus domestica, Prunus padus, Prunus serotina, Prunus spinosa, Robinia pseudo-acacia, Rosa canina, Ulmus campestris but also Euphorbia cyparissias.
The length of similar hedges can be several hundred km long, which means M. pruinosa has plenty of opportunity for spreading along the railway and infesting agricultural and ornamental cultures.
Where and on which vegetation have you observed this IAS? How much important damage have you detected?
