Evaluation of Common Methods for Sampling Invertebrate Pollinator Assemblages: Net Sampling Out-Perform Pan Traps
Methods for sampling ecological assemblages strive to be efficient, repeatable, and representative. Unknowingly, common methods may be limited in terms of revealing species function and so of less value for comparative studies. The global decline in pollination services has stimulated surveys of flower-visiting invertebrates, using pan traps and net sampling. We explore the relative merits of t...
متن کاملNotes on invertebrate drift: A pilot study
Needham (1928) first noted the ‘drift’ of aquatic insects when examining the importance of terrestrial insects as trout food. When using a fine copper wire-meshed net to collect benthos in streams near Ithaca, NY he discovered large numbers of aquatic insects present his samples. Drift attracted more attention from researchers in the 1950’s after Muller quantified drift and compared drift with ...
متن کاملSelective Sampling with Drift
Recently there has been much work on selective sampling, an online active learning setting, in which algorithms work in rounds. On each round an algorithm receives an input and makes a prediction. Then, it can decide whether to query a label, and if so to update its model, otherwise the input is discarded. Most of this work is focused on the stationary case, where it is assumed that there is a ...
