An index to evaluate the quality of taxonomic publications
The number of citations is not an adequate measure of taxonomic quality, which is a view that is shared with other scientific disciplines (Seglen1997; Valdecasas et al. 2000; Walter et al. 2003). A recent editorial in Nature claims that “... citations are an unreliable measure of importance" (Anon. 2010: 850) and uses two chemistry papers as an example. The first paper was cited 182 times in th...
متن کاملThe Diversity-Weighted Living Planet Index: Controlling for Taxonomic Bias in a Global Biodiversity Indicator
As threats to species continue to increase, precise and unbiased measures of the impact these pressures are having on global biodiversity are urgently needed. Some existing indicators of the status and trends of biodiversity largely rely on publicly available data from the scientific and grey literature, and are therefore prone to biases introduced through over-representation of well-studied gr...
متن کاملDiversity Assessment of Lotic Macroalgal Flora by the Application of Taxonomic Distinctness Index
The main aim of this study was to assess the diversity of four stream algal divisions (Cyanobacteria, Chlorophyta, Ochrophyta and Rhodophyta) by comparing results obtained with taxonomic distinctness index and diversity patterns of previous studies. The data were obtained from a study made in 1000 stream segments in North American biomes. The taxonomic arrangement of the taxa was created from s...
متن کاملCross-taxonomic potential and spatial transferability of an umbrella species index.
Validation that conservation of certain species effectively protects a high proportion of co-occurring species is rare. Our previous work has suggested that an umbrella index based on geographic distribution and life history characteristics would maximize the proportion of conspecifics protected per unit area conserved. Using bird and butterfly data from three mountain ranges in the Great Basin...
متن کاملTaxonomic Reasoning
In formalizing knowledge for common sense reasoning, one often needs to partition some domain. An instance of this from the Blocks World is the statement "All blocks are either held, on the table, or on another block." Although we can write this axiom in predicate calculus or in clause form for input to a theorem prover, such representations are highly space inefficient. In this paper we presen...
