Abstract. Characterizing the temporal uncertainty in palaeoclimate records is crucial for analysing past climate change, correlating events between records, assessing periodicities, identifying potential triggers and evaluating model simulations. The first global compilation of speleothem isotope by SISAL (Speleothem Isotope Synthesis Analysis) working group showed that age uncertainties are not systematically reported published literature, these only available a limited number (ca. 15 %,...
Abstract. Stable isotope records from speleothems provide information on past climate changes, most particularly that can be used to reconstruct changes in precipitation and atmospheric circulation. These are increasingly being “out-of-sample” evaluations of isotope-enabled models. SISAL (Speleothem Isotope Synthesis Analysis) is an international working group the Past Global Changes (PAGES) project. The aims a comprehensive compilation speleothem for reconstruction model evaluation....
Human activities are accelerating rates of biological invasions and climate-driven range expansions globally, yet we understand little how genomic processes facilitate the invasion process. Although most literature has focused on underlying phenotypic correlates invasiveness, advances in technologies showing a strong link between variation success. Here, consider ability tools to (i) inform mechanistic understanding (ii) solve real-world issues predicting managing invasions. For both,...
Abstract Invasive species threaten native ecosystems, the economy and human health. Improved understanding of an invasive species’ ecological niche, whether it has differentiated in compared to range, will enable better prediction areas at risk future invasions. Here, we characterise niche common myna ( Acridotheres tristis ) starling Sturnus vulgaris ), their range Aotearoa New Zealand, where they were introduced over 140 years ago. Common are two most bird world agricultural pests,...
Abstract In an era of global climate change, biodiversity conservation is receiving increased attention. Conservation efforts are greatly aided by genetic tools and approaches, which seek to understand patterns diversity how they impact species health their ability persist under future regimes. Invasive offer vital model systems in investigate questions regarding adaptive potential, with a particular focus on changes effective population size interact novel selection The common myna...

The common myna (Acridotheres tristis) is one of the most invasive bird species in world, yet its colonisation history only partly understood. We identified introduction and population structure, quantified genetic diversity populations from native range India introduced New Zealand, Australia, Fiji, Hawaii, South Africa, based on thousands single nucleotide polymorphism markers 814 individuals. were able to identify source mynas several locations: Fiji Melbourne, likely founded by...

Abstract How changes in the abundance and distribution of C 3 4 plants are influencing terrestrial carbon cycle is still unclear. Here, we use a simple /C model based on optimality principles to investigate impact climate-related global gross primary production (GPP) atmospheric isotopic discrimination (Δ 13 C). We estimate that fraction total including natural grasslands crops has decreased from 17.6% 14.4% over 1982–2016, despite an increase crops, reflecting declining competitive ability...
The expansion of human settlements over the past few centuries is responsible for an unprecedented number invasive species introductions globally. An important component biological invasion management understanding how introduction history and postintroduction processes have jointly shaped present-day distributions patterns population structure, diversity adaptation. One example a successful invader European starling (Sturnus vulgaris), which was intentionally introduced to numerous...
Invasive species offer uniquely replicated model systems to study rapid adaptation. The common myna (Acridotheres tristis) has been introduced over a dozen countries and is classified as one of the most invasive birds in world. Their multiple invasions provide an opportunity identify repeated adaptation, populations originated from source populations. We compared whole-genome resequencing data 80 individuals four native seven populations, representing two independent introduction pathways....
