Dear All,
during late spring and summer 2020, we captured a stunning amount of 285 males and 14 females of the otherwise rare Trichoptera Holocentropus dubius in a Malaise tent. The tent was placed not far away from eulittoral zones of Lake Remoray (Doubs dpt, Jura Mountains, France). Since these huge amounts of Holocentropus dubius were caught only in one Malaise tent (out of 4), this would imply that these specimens followed a very precise route - to where? Has anyone noticed similar faunistic movements during this exceptionally dry year 2020?
In advance many thanks
Relevant answer
Answer
In the Trichoptera species, there are bursts of abundance and then, respectively, a decline, according to observations in the North Caucasus, this occurs with an interval of about 5 years.

I'm looking for bigheaded carp (silver carp Hypophthalmichthys molitrix and bighead carp H. nobilis) occurrence data from European waters. Faunistic records are mainly published in national/ local journals, and the availabilities of them are often problematic. I want to collect as much as possible. If you are the author of a paper what contains bigheaded carp occurrence data, please send me it via email (vital.zoltan@haki.naik.hu) or private message. If it has not got English summary, please write a short description also (bigheaded carp species, location, waterbody type). If you know a researcher/fish biologist, who can help me in this issue, please tell her/him.
Regards,
Zoltán VITÁL

Recently Zootaxa, among other journals, has been suppressed from the Journal Citation Report (JCR) for 2019 (2020 release) by Clarivate Analytics based on algorithms, without taking into account the specific nature of taxonomical works, and the importance of systematic/taxonomic journals such as Zootaxa for the entire field of biodiversity research on our planet. 
If you use taxonomy in any way, as an ecologist perhaps, during conservation work, making inventories for faunistic studies ... whatever it is, then please support the taxonomic community and sign the petition to Clarivate asking that the decision be reversed: https://www.gopetition.com/petitions/zootaxa-suppressed-from-2019-jcr-data-2020-release.html

Dear All
I have some Thaumaleidae larvae from Bosnia and Herzegovina. Using key of Disney (1999) I identified them as Thaumalea testacea and Thaumalea verralli. Disney lists in his key only T. verralli, T. testacea and T. truncata whereas Fauna Europaea give a checklist of few dozens of them for Europe. Are there any other keys for Thaumaleidae larvae which I could use for my material identification, and what is current list of taxa recorded from Bosnia and Herzegovina?
Thank you for any help..

Hi everyone. I am in the process of making RDAs between faunistic and environmental tables. What I don't understand is that depending on the order in which I place my environmental variables (explanatory variables) in the model, the significant variables that emerge are not necessarily the same. Could someone explain why? Is there a way to fix this problem?
Than you very much!
Relevant answer
Answer
The distribution of your species in the abundance matrix will have different interactions with the environmental data matrix. Thus the position ij of the species matrix is variable, while the values of the environmental data matrix are fixed. If you implement the RDA with the same matrixes (species and environmental), the way the environmental variables are ordered in the matrix should not interfere with the significance.

Freshwater parasites/species and their relationship to bladder cancers in North America in human or animal hosts.
Relevant answer
Answer
Hello Wilma; The intermediate host of this parasite is the snail genus Bulinus (several species). It might be easiest for you to look up the snail genera that occur in BC lakes. If that one doesn't occur there, then the parasite doesn't either. Many parasites get carried far and wide by infected hosts. Most of those introductions immediately fail because the life cycle can't be completed. Check on the snail! Best regards, Jim Des Lauriers

I'm looking for a local database for managing faunistic data.

Answer
Hello Dragomir;
I use Microsoft Access for my ant data (the usual assortment of information). My coauthor uses Filemaker. Access has a capacity limit while Filemaker doesn't. Importing data into Access is a pain while in Filemaker it isn't. Had I known anything when I started, I'd choose Filemaker.

I'm trying to identify some Didymozoid trematodes and it would really help if I could access some of the original descriptions in Satyu Yamaguti (1970) 'Digenetic trematodes of Hawaiian fishes'; however I can't find it anywhere. Anyone know where I could find a copy? Thank you.

Is there anybody that can help me with literature on faunistics, ecology and biology of Alboglossiphonia lata? And is it true that the species was previously known as Glossiphonia weberi lata? Any help on nomenclature is also welcome. I have virtually nothing, for it is an Asian species.
Relevant answer
Answer
I believe that you are correct that Glossiphonia weberi lata is a junior synonym of Alboglossiphonia lata.  There is not too much known about this species.  Some links to resources that you may find helpful are listed below:

I request you share information on "loose shell in shrimp".
Relevant answer
Answer
Dear Dr. Amit,
This information from a research could be useful; Loose shell is phenomenal known as Loose shell syndrome (LSS).  Black tiger shrimp Penaeus monodon has been reported from Indian shrimp farms since 1998 and is recognized as a major disease problem causing significant economic loss to the shrimp aquaculture sector. Unlike the rapid mortalities associated with viral pathogens such as white spot syndrome virus and yellow head virus, progression of LSS is gradual, leading to low-level progressive mortalities. The signs of LSS include a flaccid spongy abdomen due to muscular dystrophy, space between the exoskeleton and muscle, and a shrunken hepatopancreas. The feed conversion efficiency is reduced, and shrimp have poor meat quality, caused by impairment of the hepatopancreatic functions such as digestion and absorption as evidenced by the atrophy of the hepatopancreas. Histopathological investigations on LSS-affected shrimp showed shrinkage of extensor and flexor muscles with occasional hemocytic infiltration. Inview of the foregoing therefore LSS is more harmful than beneficial to the shrimp if at all.
Best regards.
