Variable vulnerability to climate change in New Zealand lizards

Scott Jarvie, Travis Ingram, David Chapple, Rodney Hitchmough, Stuart Nielsen & Joanne M. Monks
Aim: The primary drivers of species and population extirpations have been habitat loss, overexploitation, and invasive species, but human-mediated climate change is expected to be a major driver in future. To minimise biodiversity loss, conservation managers should identify species vulnerable to climate change and prioritise their protection. Here, we estimate climatic suitability for two speciose taxonomic groups, then use phylogenetic analyses to assess vulnerability to climate change. Location: Aotearoa New Zealand (NZ) Taxa: NZ lizards:...

Predicting harvest impact and establishment success when translocating highly mobile and endangered species

Johannes Fischer, Heiko Wittmer, Caio Kenup, Kevin Parker, Rosalind Cole, Igor Debski, Graeme Taylor, John Ewen & Doug Armstrong
Harvesting individuals for translocations can negatively impact source populations, a critical challenge for species reduced to small populations. Consequently, translocation cohorts often remain small, reducing the establishment probability at the destination. Balancing the potential benefits and risks of such translocations is further complicated by philopatry and natural metapopulation dynamics if the target species is highly mobile. These challenges highlight the importance of translocation feasibility assessments, but such assessments often remain qualitative to date. The critically...

Genomic trajectories of a near-extinction event in the Chatham Island black robin

Johanna von Seth, Tom van der Valk, Edana Lord, Hanna Sigeman, Remi-André Olsen, Michael Knapp, Olga Kardailsky, Fiona Robertson, Marie Hale, Dave Houston, Euan Kennedy, Love Dalén, Karin Norén, Melanie Massaro, Bruce C. Robertson & Nicolas Dussex
Abstract Background Understanding the micro-­evolutionary response of populations to demographic declines is a major goal in evolutionary and conservation biology. In small populations, genetic drift can lead to an accumulation of deleterious mutations, which will increase the risk of extinction. However, demographic recovery can still occur after extreme declines, suggesting that natural selection may purge deleterious mutations, even in extremely small populations. The Chatham Island black robin (Petroica traversi) is arguably the most inbred bird...
