Data Quality, Performance, and Uncertainty in Taxonomic Identification for Biological Assessments

Leppo4 Tetra Tech, Inc., 400 Red Brook Blvd., Suite 200, Owings Mills, Maryland 21117-5159 USA Abstract. Taxonomic identifications are central to biological assessment; thus, documenting and reporting uncertainty associated with identifications is critical. The presumption that comparable results would be obtained, regardless of which or how many taxonomists were used to identify samples, lies at the core of any assessment. As part of a national survey of streams, 741 benthic macroinvertebrate samples were collected throughout the eastern USA, subsampled in laboratories to ;500 organisms/sample, and sent to taxonomists for identification and enumeration. Primary identifications were done by 25 taxonomists in 8 laboratories. For each laboratory, ;10% of the samples were randomly selected for quality control (QC) reidentification and sent to an independent taxonomist in a separate laboratory (total n ¼ 74), and the 2 sets of results were compared directly. The results of the sample-based comparisons were summarized as % taxonomic disagreement (PTD) and % difference in enumeration (PDE). Across the set of QC samples, mean values of PTD and PDE were ;21 and 2.6%, respectively. -

It is intended to support studies where the goal is to identify aquatic insects in the field and return them to the stream unharmed. There are many reasons for conducting non-lethal bioassessment. It may be logistically simpler and quicker to return specimens to the stream rather than bringing them to the lab for identification, some groups may not want to preserve insects, or in many cases the characteristics that are most indicative of a particular invertebrate family may be best exhibited by a live specimen. -

INTRODUCTION A BRIEF HISTORY OF MAYFLY of larvae could be made by the investigator, who did CLASSIFICATION not know the taxonomic significance of many characters shown on them. Many supraspecies taxa established by Eaton were natural, although they did In the early classifications (Linnaeus 1758, et al.) all not have sufficient diagnoses. mayflies, constituting a single holophyletic genus Later (Lestage 1917, et al.) ephemeropterologists Ephemera Linnaeus 1758 (placed to artificial order paid more and more attention to larval characters Neuroptera), were divided into two groups according rather than to imaginal ones, and established classifi- to the number of imaginal caudalii – 3 or 2.

A Reclassification of Siphlonuroidea (Ephemeroptera)

GONSER3 'Department of Entomology, St. Petersburg State University, St. Petersburg 199034, Ru ssia 2Department of Entomology, Institute of Zoology, Perolles, CH-1700 Fribourg, Switzerland 3Limnological Research Center, EA WAG, CH-6047 Kastani enbaum, Switzerland The superfamily Siphonuroidea is proposed, its phylogenetic position discussed and definitive char acteristics are presented for all the families contained. New characters of the thorax, the female gen italia, and the egg chorion are used. The Siphlonuroidea consist of a Northern Hemisphere group of families (Siphlonuridae s. str., Dipteromimidae, Ameletidae, Metretopodidae, Acanthametropodidae and Ametropodidae) and a Southern Hemisphere group of families (Oniscigastridae, Nesameletidae, Rallidentidae, and Ameletopsidae). The family Dipteromimidae and the subfamily Parameletinae are established. The synonymy of lsonychia polita and Acanthametropus nikolskyi is documented. Fossil Siphlonuroidea of uncertain family status are included. The rel ation ships between the families are di s cussed. Key words: eggs. Ephemeroptera, morphology, phylogeny, Siphlonuridae, Siphlonuroidea, systematics. INTRODUCTION The taxonomy and the phylogeny of Siphlonuroidea or Siphlonuridae sensu Lato are subject to different opinions. The authors that have worked on the rank and composition of this taxon (EDMUNDS, 1972; MCCAFFERTY & EDMUNDS, 1979; LANDA & SOLDAN, 1985; M CCAFFERTY, 1991; TOMKA & ELPERS, 1991; KLUGE, in press, and others) have used the taxon Siphlonuridae in different senses. These dif ferences are based on (1) the importance attached to adult versus larval characters, (2) the interpretation of characters as being synapomorphic or symplesiomorphic, (3) the paraphyletic nature of the group, and ( 4) inadequate diagnoses of many tax a. -

Effects of Amphibian Declines on Trophic Interactions in Algal
EFFECTS OF AMPHIBIAN DECLINES ON TROPHIC INTERACTIONS IN ALGAL- INSECT NEOTROPICAL STREAM COMMUNITIES by THOMAS ROSSITER BARNUM (Under the Direction of Catherine M. Pringle) ABSTRACT Understanding the effects of biodiversity declines on communities and ecosystems is one of the current grand challenges in ecology. Much research has been devoted to quantifying the effects of species loss from primary producer communities and multi-trophic communities in mesocosms, but less is known about the effects of species loss from food webs from multi- trophic communities. Studies that quantify species loss from multi-trophic communities in the field rely on observational data of populations to infer changes in the interactions between species. However, there is a lack of field data that uses direct observations of species interactions to quantify the effects of species loss on multi-trophic communities. This collection of studies utilizes stable isotopes as well as gut analyses combined with population data to quantify the effects of amphibian declines in highland Panamanian streams on food web structure of an insect-algal community. Results showed that the loss of amphibians can result in changes of resource use by grazing insect genera, but not necessarily lead to changes in their abundance. Furthermore, amphibians had a role in structuring the diatom community that grazing insects could not duplicate, providing insight for why grazing insects did not functionally compensate for grazing tadpoles. Lastly, structure of the whole food web was more resilient to species loss than expected based on models that assume fixed trophic linkages due to a reorganization of the food web, which was driven by shifting resource use and the presence of generalist consumers that immigrated into the community following amphibian declines. -
