Mountains create steep environmental gradients that are sensitive barometers of climate change. We calibrated 10 statistical models to formulate ensemble ecological niche for 12 predominantly alpine, flightless grasshopper species in Aotearoa New Zealand, using their current distributions and conditions. Niche were then projected two future global scenarios: representative concentration pathway (RCP) 2.6 (1.0°C rise) RCP8.5 (3.7°C rise). Results specific, with two-thirds our suggesting a...
Abstract Aim Species living on steep environmental gradients are expected to be especially sensitive global climate change, but little is known about the factors influencing their responses contemporary warming. Here, we investigate influence of biogeography three alpine species with overlapping ranges. Location Te Waipounamu (South Island) Aotearoa–New Zealand. Taxon Endemic adapted Catantopinae grasshoppers. Methods We used niche modelling estimate and project potential focal under past...
Abstract The evolutionary history of the Malus genus has not been well studied. In current study, we presented genetic evidence on origin based genome sequencing 297 accessions, revealing relationship between wild species and cultivated apples. Our results demonstrated that North American East Asian are closer to outgroup (pear) than Central species, hybrid including natural (separated before Pleistocene, about 2.5 Mya) artificial hybrids (including ornamental trees rootstocks) species....
Abstract Leptospermum scoparium J. R. Forst et G. Forst, known as mānuka by Māori, the indigenous people of Aotearoa (New Zealand), is a culturally and economically significant shrub species, native to New Zealand Australia. Chemical, morphological phylogenetic studies have indicated geographical variation across its range in Zealand, genetic differentiation between We used pooled whole genome re-sequencing 76 L. outgroup populations from Australia compile dataset totalling ~2.5 million...
Abstract The assessment of the genetic structuring biodiversity is crucial for management and conservation. This particularly critical widely distributed highly mobile deep‐water teleosts, such as hoki ( Macruronus novaezelandiae ). species significant to Māori people supports largest commercial fishery in New Zealand, but uncertainty about its stock structure presents a challenge management. Here, we apply comprehensive genomic analysis shed light on demographic this by (1) assembling...
Abstract The kākāpō is a critically endangered, intensively managed, long-lived nocturnal parrot endemic to Aotearoa New Zealand. We generated and analyzed whole-genome sequence data for nearly all individuals living in early 2018 (169 individuals) generate high-quality species-wide genetic variant callset. leverage extensive long-term metadata quantify genome-wide diversity of the species over time present new approaches using probabilistic programming, combined with phenotype dataset...
Resistance to the pandemic strain of Austropuccinia psidii was identified in New Zealand provenance Leptospermum scoparium, Kunzea robusta, and K. linearis plants. Only 1 Metrosideros excelsa-resistant plant found (of 570 tested) no resistant plants either Lophomyrtus bullata or L. obcordata were found. Three types resistance scoparium. The first two, a putative immune response hypersensitive response, are leaf mechanisms other myrtaceous species while on lateral main stems stem also...
Abstract Leptospermum scoparium is the basis of a flourishing honey industry in Aotearoa New Zealand (NZ) and Australia. The genetic structure L. across its range NZ Australia was previously assessed using pooled, whole genome sequencing; however, only one sampling site Tasmania included. Here, we used single nucleotide polymorphism (SNP) array for genotyping samples collected natural stands around NZ, to determine relationship between individuals from two regions. In total, 2069 high...
Reliable and high-throughput genotyping platforms are of immense importance for identifying dissecting genomic regions controlling important phenotypes, supporting selection processes in breeding programs, managing wild populations germplasm collections. Amongst available tools, single nucleotide polymorphism arrays have been shown to be comparatively easy use generate highly accurate genotypic data. Single-species the most commonly used type so far; however, some multi-species developed...
Abstract The range of a species is controlled by biotic and abiotic factors; both could have changed recently due to human activity. We used environmental modelling, morphometric genetic data interpret ecological responses at the boundary pair New Zealand grasshoppers with very different ranges; one widespread ( Phaulacridium marginale ) restricted semi‐arid central/southern South Island otagoense ). Climate‐ habitat‐based distribution models for in past (last glacial maximum), present...
Rewarewa (Knightia excelsa, Proteaceae) is a tree species endemic to Aotearoa New Zealand, with natural distribution spanning Te Ika-a-Māui (North Island) and the top of Waipounamu (South Island). We used pseudo-chromosome genome assembly rewarewa as reference whole pooled sequencing from 35 populations sampled across including trees growing on Māori-owned land, identify 1,443,255 single nucleotide polymorphisms (SNPs). Four genetic clusters located in northern North Island (NNI), eastern...
Abstract Cold‐adapted species are likely to have had more widespread ranges and greater population connectivity during the last glacial period than is case today. This contrasts with trend in many for range size increase interglacials. We examined pattern of genetic morphological variation within an endemic, wingless, alpine grasshopper Sigaus australis (Orthoptera: Acrididae) Southern Alps New Zealand, testing isolation by distance using geometric morphometric mitochondrial ND2 sequences...
Aotearoa New Zealand has a fauna of endemic alpine grasshoppers, consisting thirteen species distributed among four genera. The many re-classifications within this group and the presence complexes highlight uncertainty that surrounds relationships between these High-throughput Next Generation Sequencing was used to assemble complete mitochondrial genomes, 45S ribosomal cassettes histone sequences Zealands genera: Alpinacris, Brachaspis, Paprides Sigaus. Phylogenetic analysis molecular...
(1) Background: Originally described as a single taxon, Peripatoides novaezealandiae (Hutton, 1876) are distributed across both main islands of New Zealand; the existence multiple distinct lineages live-bearing Onychophora this spatial range has gradually emerged. Morphological conservatism obscured true endemic diversity, and inclusion molecular tools been instrumental in revealing these cryptic taxa. (2) Methods: Here, we review diversity ovoviviparous Zealand through re-analysis allozyme...

Abstract Host plant cues are known to shape insect–host association in many insect groups. More pronounced associations generally manifested specialist herbivores, but little is generalist herbivores. We used a polyphagous native beetle from New Zealand, bronze beetle, Eucolaspis sp. ‘Hawkes Bay’ (Chrysomelidae: Eumolpinae) explore the role of olfaction locating host plants and local adaptation. also tested other degree acceptance or rejection hosts. Adult beetles were attracted fresh leaf...
The skills, insights, and genetic data gathered by molecular ecologists are pivotal to addressing many contemporary biodiversity, environmental, cultural, societal challenges. Concurrently, the field of ecology is being revolutionised rapid technological development diversification in scope its applications. Hence, it timely review future opportunities ecological research Aotearoa New Zealand, reconcile them with philosophies open science implications for Indigenous sovereignty benefit...
Abstract Aotearoa New Zealand’s swamp forests have experienced significant habitat loss in fewer than two hundred years. Many of the country’s tree species are endemic with sparse to no genetic information available underpin conservation strategies. Syzygium maire , Aotearoa’s only species, is a culturally and ecologically important component forest habitats. Unfortunately, populations S. been greatly reduced, heavily fragmented susceptible emergent pathogen Austropuccinia psidii (myrtle...
