Why surveys? Why insect surveys? Survey results. Photo gallery Why surveys? Top Biodiversity surveys are an important tool in ecological research of tropical ecosystems, identification of conservation priorities, assessment of sustainable use of biodiversity resources, and monitoring of environmental impact of various economic activities, such as logging, mining or agriculture. Why insect surveys? Top Because of the tremendous diversity of plants and animals in tropical ecosystems, it is necessary to focus on target groups. Desired features for target taxa include (1) generality of distribution, with members of the group found in various habitats and areas; (2) specialization to different habitats and forest types at the species level; (3) known or suspected correlation of distribution and abundance with environmental perturbation; (4) readily identifiable without specialized training, at least once the local fauna is known; and (5) readily sampled with quantitative methods, providing high quality data for statistical analysis. Insects are, together with plants and vertebrates, standard part of biodiversity surveys, primarily due to their high species diversity (e.g., probably some 300,000 species in New Guinea). Among various survey methods and target taxa, light-trapping of moths (Lepidoptera) have become the most often used approach in biodiversity surveys. Light-trapping is a sampling method of choice as it is a mass-sampling technique that allows rapid, repeatable sampling by non-specialists. High species richness of the Lepidoptera and their close association with vegetation, together with the availability of established sampling protocols, make them exceptionally suitable as a focal taxon for the study of biodiversity patterns. Another target taxa which can be considered are butterflies (Papilionoidea) and ants (Formicidae). The butterflies are a well-known taxon and their response to habitat disturbance has been studied in great detail. Butterfly surveys can also provide assessment of the butterfly farming potential of the site. The only diasadvantage of this taxon is time-consuming sampling method, i.e. individual collecting along transects. The ants can provide complementary information to that on moths and butterflies as they represent a different trophic level - unlike herbivorous Lepidoptera, the ants are the most important invertebrate predators in rainforest ecosystems. Survey results: Top Our Center can deliver the following results from insect biodiversity surveys: Data on community composition of target insect taxa and their taxonomic and ecological analysis, including practical suggestions (depending on the aim of the survey) Insect voucher specimens, identified and deposited at the PNG National Insect collection Database of insect specimens and species, including quantitative information from the survey and digital images of all species Training of local assistants in the surveyed area, including training for the follow-up surveys.
