Taxonomy Laboratory

How to select a taxonomy laboratory.
If you are not processing your own macroinvertebrate or periphyton samples, you will be faced with the important task of selecting a contractor to process the samples for you. Given that there is currently no standard by which macroinvertebrate laboratories can be certified in the US, how does one go about selecting a reliable contract laboratory? There are several things you can do that will help you during the selection process to avoid serious data quality issues later on.

Sample collection and preservation.
We offer some guidelines for the methods employed in the collection and preservation of samples for lab processing, including the type and sourcing of sample containers, permanent labeling, and the preservation of samples using ethanol or isopropanol.

Laboratory sample packaging and shipping.
Here at EcoAnalysts, Inc. our number one priority is providing our clients with the best data possible. That begins with best sample handling practices to avoid samples being lost during shipping. If you have a certified Hazardous Materials Shipper, consult them for all shipping concerns. If you do not have one, or have any questions the following steps are to assist you and your company in getting samples to EcoAnalysts legally and intact. In the past, failure to follow each of these steps has resulted in samples being lost or seized during the shipping process, either from breakage or the seizure and destruction of packages for being illegal HazMat shipments.

A new genus and species of Apseudidae, and a new species of Bunakenia (Crustacea: Tanaidacea: Apseudomorpha) from the Northwest Atlantic and Gulf of Mexico 2022
Examination of material from the Campeche region of the southern Gulf of Mexico revealed the presence of a new genus and species of Apseudidae that appears to be transitional between Bunakenia Guţu and Apseudes Leach sensu lato. This new taxon, Pseudobunakenia anablesis n. gen., n. sp. is found throughout the Gulf of Mexico (GOM) and Northwest Atlantic as far north as South Carolina. It is known in the literature under the designation “Apseudes spinosa” Sars sensu Dawson and “Apseudes sp. A” (Heard et al.). Also, Bunakenia hamata n. sp. is described from offshore Georgia and is distributed from the Florida Gulf Coast and the Northwest Atlantic as far north as South Carolina.

Mexctenapseudes boeschi, a new tanaidacean genus and species from the Mexican coast of Campeche… 2022
Two new genera of parapseudid Tanaidacea belonging to the Discapseudes-Halmyrapseudes Complex sensu Heard et al. (=Complex) are designated from Mexican and Australian waters. Mexctenapseudes boeschi n. gen., n. sp. is described from Campeche Mexico and Pseudolongiflagrum n. gen. is designated from Australia. The new Mexican genus displays similarities to the West Pacific and Indian Ocean genera Ctenapseudes Bamber, Ariyananda & Silva, 1997 and Longiflagrum Guţu, 1995.

Determining the quality of taxonomic data
In this article, Stribling et al. discuss data quality issues to be considered when conducting taxonomic analyses for biological assessments. They differentiate between 2 broad areas of taxonomy—research and production taxonomic investigations—and consider how approaches to organism identification can vary between these 2 areas. The authors stress the importance of evaluating and communicating data quality, and that knowledge of quality assurance/quality control elements is essential before drawing conclusions from biological assessment results.

Benthic invertebrate response to restoration activities in Paradise Creek, Moscow, Idaho from 1994-2014
Several stream restoration activities on Paradise Creek within the City of Moscow limits have taken place since the mid-1990s. The Idaho DEQ Beneficial Use Reconnaissance Project (BURP) has performed biological monitoring at several sites in the study reach since 1994. A look at benthic invertebrate community condition showed some improvements in relation to physical habitat restoration activities within the city limits…

Development of Idaho Macroinvertebrate Temperature Occurrence Models
Federal regulations implementing the Clean Water Act (CWA) require states to specify appropriate uses to be achieved and protected for their waters (40 CFR 131.10). The CWA requires that, wherever attainable, all waters of the nation be protected for “propagation of fish and shellfish, and wildlife and provides for recreation in and on the water.” This is often shortened to the statement that waters must be “fishable and swimmable.” These are the minimum set of uses, unless unattainable.

Effects of nutrient replacement on benthic macroinvertebrates in an ultraoligotrophic reach of the Kootenai River, 2003–2010
Large impoundments remove substantial amounts of sediment and nutrients from rivers and often limit production by downstream primary producers and secondary consumers. Nutrient levels and macro-invertebrate and fish abundance in the lower Kootenai River (7th order, mean annual discharge = 454 m3/s) in Idaho and Montana declined dramatically after Libby Dam was built in 1972. A subsequent study implicated ultraoligotrophic conditions (total dissolved P [TDP] ≤ 2 μg/L TDP) as a principal causative agent and prompted an on-going experimental nutrient-addition program for the Kootenai River downstream from Libby Dam, with dosing at the Idaho–Montana border.
