Scenarios Flashcards
Several dune management interventions have been planned to improve ground-dwelling terrestrial invertebrate diversity at coastal sites in Wales. You are an ecological consultancy bidding for tender to do the survey work to establish the efficacy of the interventions…
What sampling methods will you apply and why?
What will you measure/what outcomes will you report?
systematic/random/stratified pitfall traps
Shannon’s index
number of diversity
number of species
effective number species
ordination
One of your colleagues has gathered some data regarding the community of gnaphosids, mites and opiliones at sites given varying restoration treatments at a local china clay works. The data (below), include both a site x species matrix and environmental variables. She wants to know if there is a way to represent the ecological relationships between the taxa AND the environmental variables at the same time. What else could you calculate from these data?
constrained/unconstrained ordination plot
NMDS ordination
regression analysis with different statistical distribution (Poisson)
generalised linear model
more stats test=more likely to get errors such as false positives
bonferroni correction
total abundance
One of your friends has decided to take up entomology as a hobby. She asks for advice on how to start and maintain a collection and if she can do anything more useful with her samples.
What advice can you now give her?
Make sure every sample has her name, date, proper location, report to the societies.

Follow sampling guidelines
You are at a conference and get chatting with a potential new colleague from NHM, London. He is interested in tipulid fly larvae. There are many pest species and they are hard to identify. He knows you have some expertise in molecular methods.
Can you recommend any methods to characterise the community of tipulids in UK farmlands?
What challenges and difficulties might you need to warn your potential collaborator about?
DNA sequencing
barcoding
produce a BLAST
sanger sequencing
morphological characteristics
