Solving sampling bias problems in presence–absence or presence-only species data using zero-inflated models (2021)
Journal Article
Nolan, V., Gilbert, F., & Reader, T. (2022). Solving sampling bias problems in presence–absence or presence-only species data using zero-inflated models. Journal of Biogeography, 49(1), 215-232. https://doi.org/10.1111/jbi.14268

Aim: Large databases of species records such as those generated through citizen science projects, archives or museum collections are being used with increasing frequency in species distribution modelling (SDM) for conservation and land management. De... Read More about Solving sampling bias problems in presence–absence or presence-only species data using zero-inflated models.

Target-group backgrounds prove effective at correcting sampling bias in Maxent models (2021)
Journal Article
Barber, R. A., Ball, S. G., Morris, R. K., & Gilbert, F. (2022). Target-group backgrounds prove effective at correcting sampling bias in Maxent models. Diversity and Distributions, 28(1), 128-141. https://doi.org/10.1111/ddi.13442

Aim: Accounting for sampling bias is the greatest challenge facing presence-only and presence-background species distribution models; no matter what type of model is chosen, using biased data will mask the true relationship between occurrences and en...

Mapping the evolution of accurate Batesian mimicry of social wasps in hoverflies (2021)
Journal Article
Leavey, A., Taylor, C. H., Symonds, M. R. E., Gilbert, F., & Reader, T. (2021). Mapping the evolution of accurate Batesian mimicry of social wasps in hoverflies. Evolution, https://doi.org/10.1111/evo.14336

Hoverflies (Diptera: Syrphidae) provide an excellent opportunity to study the evolution of Batesian mimicry, where defenseless prey avoid predation by evolving to resemble defended “model” species. Although some hoverflies beautifully resemble their... Read More about Mapping the evolution of accurate Batesian mimicry of social wasps in hoverflies.

Historical maps confirm the accuracy of zero‐inflated model predictions of ancient tree abundance in English wood‐pastures (2021)
Journal Article
Nolan, V., Reader, T., Gilbert, F., & Atkinson, N. (2021). Historical maps confirm the accuracy of zero‐inflated model predictions of ancient tree abundance in English wood‐pastures. Journal of Applied Ecology, 58(11), 2661-2672. https://doi.org/10.1111/1365-2664.13996

Ancient trees have important ecological, historical and social connections, and are a key source of dead and decaying wood, a globally declining resource. Wood-pastures, which combine livestock grazing, open spaces and scattered trees, are significan...
