Faunistics - Science topic

Dear Prof. Cliff Keil,

Thank you very much for your long interest on my research. As a retired emeritus professor, I'm presently decreasing my work to three mornings per week only, and I don't know what I shall do next year, but surely lesser than

in 2023. It will probably depend on my health,

Best regards,

Eduard Petitpierre

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.

My Dear'

Of course!

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.

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

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.

Best regards, Jim des Lauriers

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:

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.

Dr. Daniel
