Published in 2017 at "Environmental Biology of Fishes"

DOI: 10.1007/s10641-017-0610-5

Abstract: Unprecedented threats to natural ecosystems mean that accurate quantification of biodiversity is a priority, particularly in the tropics which are underrepresented in monitoring schemes. Data from a freshwater fish assemblage in Trinidad were used to… read more here.

Published in 2021 at "Crop Protection"

DOI: 10.1016/j.cropro.2021.105713

Abstract: Abstract Quantifying detectability of exotic pests in local contexts is crucial for designing efficient and regionally relevant surveillance guidelines. Ironically, for areas most in need of preparedness advice, the study of detectability is hampered by… read more here.

Published in 2017 at "Ecological Modelling"

DOI: 10.1016/j.ecolmodel.2017.08.021

Abstract: Abstract In retrospective studies, discrete population units such as ponds may be resurveyed at a later time using only the set of initially occupied sites. There are possible confoundings that affect estimates of occupancy change… read more here.
