Citizen science adds ecological value in urban greenspaces
Corey Callaghan, UNSW

Urban greenspaces are intensively used for multiple purposes, including biodiversity conservation. Citizen science projects (i.e., The Atlas of Australian Birds, eBird) are increasingly used to collect biodiversity data to inform conservation management. eBird is a global citizen science project, providing a potential long-term avian monitoring tool, however the validity of the data at small-scales remains largely unresolved. We tested eBird’s ability to provide comparable avian biodiversity estimates compared to formal surveys in an urban greenspace in Sydney. We found that eBird provided higher species richness and Shannon diversity indices than structured surveys, as a result of increased effort (i.e., time spent surveying, number of observers, and spatial coverage). We then assessed eBird data from 30 unique urban greenspaces in North America over six years, and found that in order to estimate 90% of species richness at a site, ~16.7 ± 2.3 (mean ± sd) eBird checklists were required. We (1) demonstrate that eBird provides comparable biodiversity estimates to structured surveys, (2) a surprisingly low number of eBird lists are required to fully sample an avian community in an urban greenspace, and (3) eBird data can be used to answer ecological questions at spatial and temporal scales previously unrecognized.

 

Caprellids: Extraterrestrials from the sea. The importance of Caprellid collections of the Australian Museum
Dr José Guerra García, University of Seville, Spain

Caprellids are small peracaridean crustaceans which inhabit marine ecosystems. They are abundant in many environments, depths and substrates; however, they are not very well known, and many species still remain undescribed. These little marine animals, known as skeleton shrimps, are very useful as bioindicators of water quality and as a resource in aquaculture. Australian Museum host 34 genera, 74 species and 160 types of these amazing creatures; therefore, this collection can be considered as one of the best in the world.
