Data from: Cost-effective large-scale occupancy–abundance monitoring of invasive brushtail possums (Trichosurus vulpecula) on New Zealand’s Public Conservation Land

Andrew M. Gormley, David M. Forsyth, Elaine F. Wright, John Lyall, Mike Elliott, Mark Martini, Benno Kappers, Mike Perry & Meredith McKay
There is interest in large-scale and unbiased monitoring of biodiversity status and trend, but there are few published examples of such monitoring being implemented. The New Zealand Department of Conservation is implementing a monitoring program that involves sampling selected biota at the vertices of an 8-km grid superimposed over the 8.6 million hectares of public conservation land that it manages. The introduced brushtail possum (Trichosurus Vulpecula) is a major threat to some biota and is...

Data from: Biodiversity gains from efficient use of private sponsorship for flagship species conservation

Joseph R. Bennett, Richard Maloney & Hugh P. Possingham
To address the global extinction crisis, both efficient use of existing conservation funding and new sources of funding are vital. Private sponsorship of charismatic ‘flagship’ species conservation represents an important source of new funding, but has been criticized as being inefficient. However, the ancillary benefits of privately sponsored flagship species conservation via actions benefiting other species have not been quantified, nor have the benefits of incorporating such sponsorship into objective prioritization protocols. Here, we use...

Data from: Unexpected positive and negative effects of continuing inbreeding in one of the world’s most inbred wild animals

Emily L. Weiser, Catherine E. Grueber, Euan S. Kennedy & Ian G. Jamieson
Inbreeding depression, the reduced fitness of offspring of related individuals, is a central theme in evolutionary biology. Inbreeding effects are influenced by the genetic makeup of a population, which is driven by any history of genetic bottlenecks and genetic drift. The Chatham Island black robin represents a case of extreme inbreeding following two severe population bottlenecks. We tested whether inbreeding measured by a 20-year pedigree predicted variation in fitness among individuals, despite the high mean...

Data from: Evidence for Bergmann's rule and not allopatric subspeciation in the threatened kaka (Nestor meridionalis)

Nic Dussex, James Sainsbury, Ron Moorhouse, Ian G. Jamieson & Bruce C. Robertson
Species of conservation concern characterized by small and declining populations greatly benefit from proactive management approaches such as population translocations. Because they often show intra-specific genetic and phenotypic variation, which can result from drift or differential selective pressures between habitats, understanding the distribution of such variation and its underlying processes is a prerequisite to develop effective management guidelines. Indeed, translocations among genetically differentiated populations potentially locally adapted are discouraged in order to avoid outbreeding depression,...

Data from: Heterozygote advantage at MHC DRB may influence response to infectious disease epizootics

Amy J. Osborne, John Pearson, Sandra S. Negro, B. Louise Chilvers, Martin A. Kennedy & Neil J. Gemmell
The effect of MHC polymorphism on individual fitness variation in the wild remains equivocal; however, much evidence suggests that heterozygote advantage is a major determinant. To understand the contribution of MHC polymorphism to individual disease resistance or susceptibility in natural populations, we investigated two MHC class II B loci, DQB and DRB, in the New Zealand sea lion (NZSL, Phocarctos hookeri). The NZSL is a threatened species which is unusually susceptible to death by bacterial...
