“…Systematists have developed and incorporated a variety of technologies into their methods to enable more efficient analyses and communication of results. These include high-tech imaging systems, statistical software packages, and high-throughput DNA sequencing (Goldstein & DeSalle, 2011). The generation and communication of biological data through modern 43 taxonomic techniques is relied upon for the conservation, economic, and social uses of biodiversity.…”

“…Systematists often juggle many important responsibilities: they are custodians of biological knowledge accumulated over centuries; they are curators of vast collections holding three billion specimens worldwide and representing millions of human-hours in effort; they are cataloguers of biodiversity who are racing the clock against extinctions; and increasingly, they are seen as service providers of species identifications and datasets (Patterson, 2010;Goldstein & DeSalle, 2011;Wheeler, 2010). Most biologists depend on accurate species identifications, meaningful schemes of biological classification, and informative scientific names that allow the storage and communication of information about an organism: all are products of careful taxonomic study (Wheeler, 2009b).…”

“…Such proposals have inevitably drawn criticism from taxonomists and others who are concerned at the empirical and theoretical flaws characterising 'DNA taxonomy' as it is currently practised (Taylor & Harris, 2012;Goldstein & DeSalle, 2011;Lipscomb et al, 2003;Seberg et al, 2003). DNA proponents argue that "DNA sequence information is digital and is not influenced by subjective assessments" (Tautz et al, 2003, p. 71).…”

Optimising Capture Methods for the Evaluation of Parasitoid Wasp Diversity

Parasitoid wasps are mega-diverse, ecologically dominant, but poorly studied components of global biodiversity. Despite their intensive application within pest management as biocontrol agents, little is known about native species. To understand their basic biology they must be collected in sampling programs. However, invertebrate surveys are increasingly subject to funding and time constraints that often preclude complete faunal inventories. In order to maximise the efficiency and reduce the cost of their collection, the application of optimal sampling techniques within a Rapid Biodiversity Assessment framework is proposed. Two sites in the Waitakere Ranges were sampled three times over the summer. An intensive sampling effort of 840 Malaise-trap-days over a three month period was used to determine the relationship between sampling effort and observed species richness. Rarefaction techniques and non-parametric estimators were used to predict true species richness and to evaluate the completeness of sampling. Results show that an intensive Malaise-trapping regime over the summer can capture two-thirds of parasitoid wasp species present. Sampling recommendations are provided to guide optimal usage of Malaise traps for both ecological studies and faunal inventories. Modern taxonomic methods are reviewed and a new species of parasitoid wasp is described, representing the first New Zealand species from the genus Lusius (Ichneumonidae: Ichneumoninae). Morphological measurements confirm the new species represents a significant range expansion for the genus. Greater collaboration between ecologists and taxonomists is encouraged, in order to make more efficient use of resources, data, and expertise unique to each discipline. This is the first study to investigate the relationship between sampling effort and parasitoid wasp diversity in New Zealand. It shows that very high sampling effort fails to catch all species present. Parasitoid wasps are known to be keystone species that show promise as indicators of environmental quality and as surrogates for the diversity of other taxa. The development of optimal sampling strategies will therefore provide an important foundation for their future study.

“…More specifically, ABGD act based on the similarity criterion that genetic distances between specimens from close species are supposed to be lower than genetic distances between specimens from different species (Hebert et al, 2003). Therefore, ABGD analysis can be used as a primary glance for the species identification that is, primary species hypotheses (PSHs, Goldstein and DeSalle, 2011).…”

Geographically isolated populations of Barbus present remarkable variation with regard to morphometric and meristic characters within Iranian drainage systems; while they are relatively similar in external morphology such as coloration. Present study is the first report on geographical differentiation of Barbus populations in Iran from both morphological and molecular point of views. The morphometric and meristic characters as well as phylogenetic relationships (using sequence data of mtDNA cytochrome b gene) of twelve populations from three drainages (i.e. South Caspian Sea, Orumyieh and TigrisKaroun) were analyzed. The univariate analysis reveals significant morphological differentiation among the populations from the three drainages. The phylogenetic analyses indicate relatively high genetic differentiation among the populations from the mentioned drainages, which are consistent with the observed morphological variation, and correspond well with their biogeographic distribution. However, the result of Automatic Barcode Gap Discovery (ABGD) analysis shows intra-specific differentiation for the sequences from South Caspian Sea drainage, while support the distinction of the specimens from TigrisKaroun drainage as B. lacerta. Since the sequence data of Barbus cyri from Armenia is clustered with individuals from the South Caspian Sea and the morphological comparison, the specimens from that basin are considered as B. cyri and the Orumyieh basin as Barbus sp.

Towards the unravelling of the slug <i>A. ater–A. rufus</i> complex (Gastropoda Arionidae): new genetic approaches

Abstract. The genus Arion includes several slug species, some of which are considered to be a pest to both cultivated and wild flora. Within this genus, the Arion ater complex comprises two different morphological forms: Arion rufus and A. ater, but there is no consensus about their species status. Their phylogenetic relationships have been recently solved, both of them belonging to different phylogenetic clades, but their species status is still unclear (as different clades are not always different species). For this reason, the aim of this study was to precisely identify these species status by employing the up-to-date multi-rate Poisson tree processes (mPTP) methodology as well as the classic methodology of genetic distances, both of which have three different mitochondrial genes. Results confirmed that both A. ater and A. rufus are independent evolutionary clades, and the high genetic distances between them (K2P distances ranged between 9.1 and 16.4 %, depending on genes) together with mPTP analyses, supported the idea that the clades correspond to different species. Results will be useful for the classification of these specific species as well as for developing proper pest control methodologies and conservation policies in both cultivated and wild plants.
