2. Contents of the course

Theory

1. Biodiversity of invertebrates

  • A short  history of  biodiversity in the world through different periods
  • Drivers of biodiversity loss

+ Competition for food and habitat

+ Habitat degradation through pollution

+ Predation, competition

+ Disease/parasite

+ Climate change and associated global changes

+ Modification of sea level, sea temperature, sea pH,…

  • How to measure biodiversity
  • Other dimensions of biodiversity
  • Why should we care to biodiversity?

2. Overview of insects.

  • Insects: animals under threat

+ A major part of visible biodiversity

+ Extinction

+ Major threats? Habitat destruction, alteration and fragmentation

+ Most insects population are metapopulations

  • Laws to protect insects in France

+ Some protected species are “LC” species

+ Some “EN” species are not protected

+ Protection against people who collect and sell insects

+ Scientist can obtain a permit to collect samples from protected species.

+ Protection against habitat destruction and fragmentation

  • Tools for insects protection

+ Produce user-friendly keys for reliable insect determination

+ Keep memory of occurrence datas in online open database

+ Use citizen “science” to obtain more occurrence datas

+ Produce “red lists”

+ Produce and use monitoring protocols to describe long term trends

+ Develop poorly/ non invasive mehods to monitor populations

+ Study life history traits and metapopulation functioning

+ “Action plants” to protect targeted insects species

3. Online database and insect red list building

  • Introduction
  • Online database

+ Easy direct data storing

+ Data sharing

+ Data visualisation

+ Database manager

  • Basic information
  • Building an insect red list

+ Red list categories

+ Which taxa are evaluated?

+ Producing a red list require

+ Actual assessment based on 5 criteria

  • A red list: What for?

4. Sampling insect for conservation purpose

  • Different purposes for insect sampling

+ To monitor insect species

+ To evaluate management strategies

+ To examine species population

+ To evaluate conservation status and produce red list

+ To detect species of conservation,

+ To describe long term trends in abundance and diversity

  • Difficulties in sampling insects
  • Tools for insect sampling

+ Active sampling:  beating net, beating sheet, berlese funnel trap, Tullgren funnel, Box quadrat, Scounting for eggs, Scouting for larvae and cues, Scouting feeding sites, Scouting for exuviae, Scouting feeding sites to detect adult odors

+ Passive collecting: Pitfall traps, Barber traps, Flight interception/Barner/window trags, Malaise traps, Canopy traps, Light traps, Pheromone/ Kairomone baited traps, Aliment baited traps, Water pan traps, Emergence traps, Recording songs, DNA amplification

  • Some protocols: STELL (Temporal monitoring of dragenflies and damselflies), STERF (Temporal monitoring of Rhopalocera in France)

Practice

  • Methods of insect collection
  • Identified some common insects at family level: Libellulidae, Conocephalinae, Tridactilydae, Cassididae.
  • Group discussion
  • Certification: at the end of the course, all participants were awarded a certificate certified his/her participation of the course.
