Modelling Mycorrhizal Fungi Dispersal By The Mycophagous Swamp Wallaby (Wallabia Bicolor) [Dataset], Melissa Danks, Natalie Simpson, Todd F. Elliot, C.E. Timothy Paine, Karl Vernes

Research Datasets

Despite the importance of mammal-fungal interactions, tools to estimate the mammal-assisted dispersal distances of fungi are lacking. Many mammals actively consume fungal fruiting bodies, the spores of which remain viable after passage through their digestive tract. Many of these fungi form symbiotic relationships with trees and provide an array of other key ecosystem functions. We present a flexible, general model to predict the distance a mycophagous mammal would disperse fungal spores. We modelled the probability of spore dispersal by combining animal movement data from GPS-telemetry with data on spore gut-retention time. We test this model using an exemplar generalist mycophagist, …

Human Impact Overrides Bioclimatic Drivers Of Red Fox Home Range Size Globally [Dataset], Michael Main, Robert Davis, David Blake, Harriet Mills, Tim Doherty

Research Datasets

Aim Identifying the variables that influence animal home range size is important for understanding the biological requirements of individuals and their social interactions. Given their often broad distributions, carnivores are model organisms for studying range-wide determinants of home range size. Here we test predictions about environmental determinants of home range size for one of the world’s most widely distributed carnivores, the red fox (Vulpes vulpes).

Location Global

Methods We compiled a database of 70 mean home range estimates from 62 studies and four continents, which we analysed according to site-based temperature, precipitation, environmental productivity and human influence …

Hybrid Zone Barriers Comparative Data Set, David L. Field

Research Datasets

Many recent studies have addressed the mechanisms operating during the early stages of speciation, but surprisingly few studies have tested theoretical predictions on the evolution of strong reproductive isolation (RI). To help address this gap, we first undertook a quantitative review of the hybrid zone literature for flowering plants in relation to reproductive barriers. Then, using Populus as an exemplary model group, we analysed genome-wide variation for phylogenetic tree topologies in both early- and late-stage speciation taxa to determine how these patterns may be related to the genomic architecture of RI. Our plant literature survey revealed variation in barrier complexity …

New Bathynellidae (Crustacea) Taxa And Their Relationships In The Fortescue Catchment Aquifers Of The Pilbara Region, Western Australia [Dataset], Giulia Perina, Ana I. Camacho, Joel Huey, Pierre Horwitz, Annette Koenders

Research Datasets

In the past 20 years, the number of subterranean taxa discovered in Australia, especially in the Pilbara bioregion, has considerably increased due to incidental environmental surveys often associated with mining development. Bathynellidae are an important component of stygofauna and they occur in most Australian aquifers, but their collection and identification are difficult due to their habitat, and small and fragile bodies with conservative morphology. The study of Pilbaranella ethelensis in the upper Fortescue catchment contributed to a better understanding of the group at local scale, but knowledge at larger catchment scale is still limited. Abundant material collected by different environmental …
