USING TAXONOMIC REVISION DATA TO ESTIMATE THE GLOBAL SPECIES RICHNESS AND CHARACTERISTICS OF UNDESCRIBED SPECIES OF DIVING BEETLES (COLEOPTERA: DYTISCIDAE)	2010	16	.pdf	application/pdf	9426	643	53	Revision of the Nearctic Liodessus affinis (Say 1823) species group (Coleoptera: Dytiscidae, Hydroporinae, Bidessini). To be able to use species description data for this purpose, we must have considered that: 1) the effort spent on taxonomic discovery and description varies greatly over time and between regions; 2) curves showing the rate of description plotted against time often displays a distinct ―lag phase‖ of low description rates in the initial stage; 3) the precise relationship between taxonomic effort and description rate is poorly understood, making it difficult to justify which model to fit to the data; 4) the description process frequently proceed in pronounced leaps marking the publication of important monographic works and revision which are impossible to predict using extrapolation techniques; 5) if there is no sign of decrease in the rate of description over NILSSON-ÖRTMAN & NILSSON - USING TAXONOMIC REVISION DATA TO ESTIMATE SPECIES RICHNESS 7 time, extrapolating techniques cannot be applied (White 1979).	cache/jbi-3631.pdf	txt/jbi-3631.txt
