Data for the manuscript: Historical biogeography of Pomaderris (Rhamnaceae): continental vicariance in Australia and repeated independent dispersals to New Zealand

Francis Nge
Gondwanan biogeographic patterns include a combination of old vicariance events following the breakup of the supercontinent, and more recent long-distance dispersals across the southern landmasses. Floristic relationships between Australia and New Zealand have mostly been attributed to recent dispersal events rather than vicariance. We assessed the biogeographic history of Pomaderris (Rhamnaceae), which occurs in both Australia and New Zealand, by constructing a time-calibrated molecular phylogeny to infer (1) phylogenetic relationships and (2) the relative contributions...

Re-allocation of nitrogen and phosphorus from roots drives regrowth of grasses and sedges after defoliation under deficit irrigation and nitrogen enrichment

Ruzhen Wang, Tom Cresswell, Mathew Johansen, Jennifer Harrison, Yong Jiang, Claudia Keitel, Timothy Cavagnaro & Feike Dijkstra
1. Re-allocation of nutrients from roots to shoots is essential for plant regrowth in grasslands, particularly in nutrient-poor conditions. However, the response of root nutrient re-allocation to changes in nitrogen (N) and water availability remains largely unknown. 2. Using a novel 15N and 32P labelling technique, we quantified the contribution of N and phosphorus (P) to shoot regrowth from either root re-allocation or direct soil uptake for perennial grasses exposed to high-frequency deficit irrigation (HFDI)...

Supplemental Material for \"Biomechanical analyses of Cambrian euarthropod limbs reveal their effectiveness in mastication and durophagy\"

Russell Bicknell, James Holmes, Gregory Edgecombe, Sarah Losso, Javier Ortega-Hernández, Stephen Wroe & John Paterson
Durophagy arose in the Cambrian and greatly influenced the diversification of biomineralised defensive structures throughout the Phanerozoic. Spinose gnathobases on protopodites of Cambrian euarthropod limbs are considered key innovations for shell-crushing, yet few studies have demonstrated their effectiveness with biomechanical models. Here we present finite element analysis models of two Cambrian trilobites with prominent gnathobases—Redlichia rex and Olenoides serratus—and compare these to the protopodites of the Cambrian euarthropod Sidneyia inexpectans and the modern American horseshoe...

An integrated phylogenetic reassessment of the parasitoid superfamily Platygastroidea (Hymenoptera: Proctotrupomorpha) results in a revised familial classification

Chen Huayan, Lahey Zachary, Elijah J. Talamas, Alejandro A. Valerio, Ovidiu A. Popovici, Luciana Musetti, Hans Klompen, Andrew Polaszek, Lubomír Masner, Andrew D. Austin & Norman F. Johnson
The superfamily Platygastroidea (Hymenoptera: Proctotrupomorpha) is a diverse group of parasitoid wasps that attack nine orders of insects as well as spiders. They appear to show a clear pattern of host group specificity among genera. A robust phylogeny is essential to understanding the monophyly of and relationships among lower level groups and the pattern of the shifts among host groups. We conducted phylogenetic analyses of Platygastroidea based on four molecular markers (18S, 28S, COI, and...

Clinical data for individuals from families with SLC32A1 variants

Jozef Gecz & Sarah Heron
Objective: To identify the causative gene in a large unsolved family with genetic epilepsy with febrile seizures plus (GEFS+), we sequenced the genomes of family members, and then determined the contribution of the identified gene to the pathogenicity of epilepsies by examining sequencing data from 2772 additional patients. Methods: We performed whole genome sequencing of three members of a GEFS+ family. Subsequently, whole exome sequencing (ES) data from 1165 epilepsy patients from the Epi4K dataset...

Data from: Land-use legacies influence tree water-use efficiency and nitrogen dynamics in recently established European forests

Rossella Guerrieri, Marta Correia, Irene Martín-Forés, Raquel Alfaro-Sánchez, Joan Pino, Arndt Hampe, Fernando Valladares & Josep Espelta
1. Forest regrowth following farmland (agriculture and pasture) abandonment has been positively associated with a number of processes including the regulation of hydrological cycling, the enhancement of soil functioning, and an increase in forest productivity and carbon (C) sequestration. Although these changes in ecosystem functioning post-farmland abandonment have been observed in multiple locations and studies, the ecophysiological basis underpinning these patterns remains unclear. Here, we examine whether increased forest expansion following pastureland abandonment is associated...

The behavioural responses of Lasiorhinus latifrons to night-time and daytime drone flight

Taylor Headland, Bertram Ostendorf & David Taggart
The use of drones in wildlife research and management is increasing. Recent evidence has demonstrated the impact of drones on animal behavior but the response of nocturnal animals to drone flight remains unknown. Utilising a lightweight commercial drone, the behavioral response of southern hairy-nosed wombats (Lasiorhinus latifrons) to drone flights was observed at Kooloola Station, Swan Reach, South Australia. All wombats flown over during both day and night flights responded behaviorally to the presence of...

Behavioural modification of range-extending coral reef fishes in temperate ecosystems

Ericka Coni, David Booth, Camilo Ferreira & Ivan Nagelkerken
1. Coral-reef fishes are shifting their distributions poleward in response to human-mediated ocean warming, yet the consequences for recipient temperate fish communities remain poorly understood. Behavioural modification is often the first response of species to environmental change, but we know little about how this might shape the ongoing colonisation by tropical fishes of temperate-latitude ecosystems under climate change. 2. In a global hotspot of ocean warming (southeast Australia), we quantified 14 behavioural traits of invading...

IUCN Red List protects avian genetic diversity

Elisabetta Canteri, Damien Fordham, Sen Li, Peter Hosner, Carsten Rahbek & David Nogues-Bravo
Despite well-established links between low genetic diversity and extinction processes, intra-specific genetic diversity is rarely considered in global conservation assessments, potentially leading to biased estimates of species’ extinction risk. We show that birds ranked as “threatened” by the IUCN Red List have lower intra-specific genetic diversity than “non-threatened” species, confirming that threat criteria, used by the IUCN, effectively protect genetically depleted species. However, some “non-threatened” species harbour low levels of genetic diversity, indicating an undetected...

Assessing candidate DNA barcodes for Chinese and internationally traded timber species

Jian-Lin Hu, Xiu-Qin Ci, Zhi-Fang Liu, Eleanor E. Dormontt, John G. Conran, Jie Li & Andrew J. Lowe
Accurate identification of species from timber is an essential step to help control illegal logging and forest loss. However, current approaches to timber identification based on morphological and anatomical characteristics have limited species resolution. DNA barcoding is a proven tool for plant species identification, but there is a need to build reliable reference data across broad taxonomic and spatial scales. Here, we construct a species barcoding library consisting of 1,550 taxonomically diverse timber species from...

Data from: Reticulate evolution, ancient chloroplast haplotypes, and rapid radiation of the Australian plant genus Adenanthos (Proteaceae)

Francis Nge
Cytonuclear discordance, commonly detected in phylogenetic studies, is often attributed to hybridisation and/or incomplete lineage sorting (ILS). New sequencing technologies and analytical approaches can provide new insights into the relative importance of these processes. Hybridisation has previously been reported in the Australian endemic plant genus Adenanthos (Proteaceae). Like many Australian genera, Adenanthos is of relatively ancient origin, and provides an opportunity to examine long-term evolutionary consequences of gene flow between lineages. Using a hybrid capture...

Data from: Optimising monitoring for trend detection after 16 years of woodland-bird surveys

Thomas Prowse, Patrick O'Connor, Stuart Collard, Kristian Peters & Hugh Possingham
1. Long-term biodiversity monitoring programs provide important information about species’ trajectories and broader environmental change. Often constrained by funding and organisational capability and commitment, monitoring programs need to be optimised to maximise ecological and economic efficiencies, as part of sound adaptive management. 2. The monitoring design requirements for detecting biodiversity trends, across assemblages of species with different traits, can be informed by historical datasets. Using data from a landscape-scale (c. 2,500 km2) bird monitoring program...

Positive species interactions strengthen in a high-CO2 ocean

Camilo Ferreira, Sean Connell, Silvan Goldenberg & Ivan Nagelkerken
Negative interactions among species are a major force shaping natural communities and are predicted to strengthen as climate change intensifies. Similarly, positive interactions are anticipated to intensify, and could buffer the consequences of climate-driven disturbances. We used in situ experiments at volcanic CO2 vents within a temperate rocky reef to show that ocean acidification can drive community reorganization through indirect and direct positive pathways. A keystone species, the algal-farming damselfish Parma alboscapularis, enhanced primary productivity...

Data from: Phylogenomics and continental biogeographic disjunctions – insight from the Australian starflowers (Calytrix: Myrtaceae)

Francis Nge
PREMISE OF THE STUDY: Continental-scale disjunctions and associated drivers is a core research interest in biogeographic studies. Here, we selected a species-rich Australian plant genus (Calytrix; Myrtaceae) as a case study to investigate these patterns in an Australian context. The endemic Australian starflower genus has a disjunct distribution across the mesic fringes of the continent and is absent from the arid centre. METHODS: We used high-throughput sequencing to generate unprecedented resolution and near complete species-level...

Run and output files from: Holocene population expansion of a tropical bee coincides with early human colonisation of Fiji rather than climate change

James B. Dorey, Scott V.C. Groom, Alejandro Velasco-Castrillón, Mark Stevens, Michael S.Y. Lee & Michael P. Schwarz
There is substantial debate about the relative roles of climate change and human activities on biodiversity and species demographies over the Holocene. In some cases, these two factors can be resolved using fossil data, but for many taxa such data are not available. Inferring historical demographies of taxa has become common, but the methodologies are mostly recent and their shortcomings often unexplored. The bee genus Homalictus is developing into a tractable model system for understanding...

Halophila johnsonii phylogenetic analysis alignments

Kor-Jent Van Dijk, Michelle Waycott, Ainsley Calladine, Eric Bricker & Ed Biffin
Halophila johnsonii is an endangered seagrass species that is restricted to the Florida Bay region of Florida, USA. Its taxonomic status has been called into question, in particular, given the close morphological and genetic similarity of H. johnsonii and the widely distributed and morphologically variable H. ovalis, which is largely restricted to the Indo-Pacific region. While a close relationship to H. ovalis is uncontroversial, it remains uncertain whether H. johnsonii represents a distinct lineage or...

Data from: The extension of foundress lifespan and the evolution of eusociality in the Hymenoptera (American Naturalist)

Jack Da Silva
The evolution of effectively sterile workers in the aculeate Hymenoptera (ants, bees and stinging wasps) requires that a female’s lifespan largely overlap that of her daughters. The evolution of long nest foundress lifespans in eusocial species from the short lifespans of solitary species is investigated. Analyses that control for phylogeny show for the first time that foundress adult lifespan increases, and first-brood offspring development time decreases, with increasing colony size, resulting in the ratio of...
