By Michael J. Samways

With as much as 1 / 4 of all insect species heading in the direction of extinction over the following few a long time, there's now a urgent have to summarize the suggestions to be had for measuring insect range as a way to increase potent conservation techniques. Insect Conservation outlines the most tools and methods to be had to entomologists, supplying a complete synthesis to be used through graduate scholars, researchers and practicing conservationists around the world. either glossy and extra 'traditional' methodologies are defined, sponsored up via functional historical past details and an international diversity of examples. many more recent concepts are integrated that have now not but been defined within the current publication literature. This publication can be really suitable to postgraduate and complicated undergraduate scholars taking classes in insect ecology, conservation biology and environmental administration, in addition to confirmed researchers in those fields. it's going to even be a important reference for nature conservation practitioners entomologists around the globe.

A Survey of the Lepidoptera, Biogeograhy and Ecology of New Caledonia

I spent 4 months in New Caledonia in 1971 with the item of creating a quantitative survey of the night-flying macrolepidoptera with light-traps and an evaluation of the Rhopalocera and microlepidoptera. This fieldwork was once financed by way of a central authority Grant-in-Aid for clinical Investigations adminis­ tered by way of the Royal Society, and via a supply from the Godman Fund.

N. Such a study has two weaknesses. First, among insects, higher taxa are generally poor surrogates for species patterns and responses to change. Second, when doing assessments for whatever reason, the use of specimens formally identified to species level makes results repeatable. This is not possible with morphospecies (but see Chapter 2 for some solutions). Using higher taxa also has reduced value for conservation, especially of endemic species. Again, this is because without species names, it is not possible to compare samples from one study to another and so see how the status of species is changing relative to environmental change.

Similarly, using simple codes in notebooks can also carry risks (notebooks can get lost), and so, whether labels or notes, it is far better right from the start to use full information that is meaningful to any other researcher. This is one of the advantages of digital data loggers, where at least spatial information (such as geographical coordinates) is automatically recorded. In remote areas, where local place names are few and far between, and can change as the political climate changes, it is essential to record exact spatial coordinates.

2 Selection of insect groups for study Inventories that are aimed at sampling all taxa in a particular area (all-taxon biological inventories, ATBIs), although noble in intent, are usually impractical. A more practical approach is to survey particular taxa (focal groups). Simply selecting groups because they reflect the individual interests of participating scientists requires caution, because ‘favourite’ taxa may not provide the best possible information for the particular ecological or conservation research question you are asking.
