Household relocation and recovery following the 2017 Edgecumbe flooding: results of a survey

Finn R. Scheele, Lucy H. Kaiser & Ryan Paulik
In April 2017, the Rangitāiki River breached a stopbank, resulting in widespread flooding within the town of Edgecumbe, Bay of Plenty. The evacuation of the town and damage to homes led to major disruption for residents. The relocation of households, both temporary and permanent, had long-lasting effects on the community. A questionnaire to gather residents’ experiences during the event and subsequent recovery was hand-delivered to residential addresses in Edgecumbe in November 2020. Topics included housing...

Sex-specific foraging of an apex predator puts females at risk of human-wildlife conflict

Hendrik Schultz, Kevin Chang, Sarah Bury, Anne Gaskett, Todd Dennis, Stefanie Ismar-Rebitz, Ian Southey, Rebecca Hohnhold & Craig Millar
Urbanisation and anthropogenic alteration of ecosystems has led to conflict between humans and wildlife. Such conflict is often observed in apex predators. Although human-wildlife conflict has been extensively studied, male/female differences in behaviour are rarely considered. We investigated male/female differences in foraging behaviour of the predatory/scavenging brown skua Catharacta antarctica lonnbergi breeding on a New Zealand island nature reserve in proximity to farmland. These skuas are subject to culling, when perceived as a threat to...

Marine soundscape variation reveals insights into baleen whales and their environment: a case study in central New Zealand

Victoria Warren, Craig McPherson, Giacomo Giorli, Kimberly Goetz & Craig Radford
Baleen whales reliably produce stereotyped vocalizations, enabling their spatio-temporal distributions to be inferred from acoustic detections. Soundscape analysis provides an integrated approach whereby vocal species, such as baleen whales, are sampled holistically with other acoustic contributors to their environment. Acoustic elements that occur concurrently in space, time and/or frequency can indicate overlaps between free-ranging species and potential stressors. Such information can inform risk assessment framework models. Here, we demonstrate the utility of soundscape monitoring in...

Data for: Warming temperatures limit the maximum body length of teleost fishes across a latitudinal gradient in Norwegian waters

Charles P. Lavin, Cesc Gordó-Vilaseca, Mark John Costello, Zhiyuan Shi, Fabrice Stephenson & Arnaud Grüss
As the majority of marine organisms are water-breathing ectotherms, temperature and dissolved oxygen are key environmental variables that influence their fitness and geographic distribution. In line with the gill-oxygen limitation theory (GOLT), the maximum asymptotic body size of water-breathing ectotherms is limited by an insufficient amount of oxygen that is supplied to meet metabolic demand once a threshold of gill surface area to body weight ratio is surpassed. Here we employed generalised additive models (GAMs)...

Data from: A global perspective on the functional responses of stream communities to flow intermittence

Julie Crabot, Cédric P. Mondy, Philippe Usseglio-Polatera, Ken M. Fritz, Paul J. Wood, Michelle J. Greenwood, Michael T. Bogan, Elisabeth I. Meyer & Thibault Datry
The current erosion of biodiversity is a major concern that threatens the ecological integrity of ecosystems and the ecosystem services they provide. Due to global change, an increasing proportion of river networks are drying and changes from perennial to non-perennial flow regimes represent dramatic ecological shifts with potentially irreversible alterations of community and ecosystem dynamics. However, there is minimal understanding of how biological communities respond functionally to drying. Here, we highlight the taxonomic and functional...

How functionally diverse are fish in the deep? A comparison of fish communities in deep and shallow‐water systems

Victoria Grace Carrington, Yvan Papa, Jessica Hall, Monique A. Ladds, Alice Rogers, Peter Horn, Raphaël Covain & Chelsey M. Beese
Aim: Functional diversity metrics inform how species’ traits relate to ecosystem functions, useful for quantifying how exploitation and disturbance impact ecosystems. We compare the functional diversity of entire fish communities in a shallow-water region with a deep-sea region for further insight into the differences between these ecosystem types. Location: The regions compared in this study were selected to represent a shallow-water coastal region, Tasman and Golden Bays (TBGB), and a deep-sea region, Chatham Rise (CR),...

A broadly resolved molecular phylogeny of New Zealand cheilostome bryozoans as a framework for hypotheses of morphological evolution

Russell Orr, E. Di Martino, D.P. Gordon, M.H. Ramsfjell, H.L. Mello, A.M. Smith & L.H. Liow
Larger and larger molecular phylogenies based on ever more genes are becoming commonplace with the advent of cheaper and more streamlined sequencing and bioinformatics pipelines. However, many groups of inconspicuous but no less evolutionarily or ecologically important marine invertebrates are still neglected in the quest for understanding species- and higher-level phylogenetic relationships using high-throughput sequencing approaches. Here, we alleviate this issue by presenting a 17 gene phylogeny of >200 newly sequenced cheilostome bryozoan species, mainly...

Delayed adaptive radiation among New Zealand stream fishes: joint estimation of divergence time and trait evolution in a newly delineated island species flock

Christine Thacker, James Shelley, William McCraney, Peter Unmack & Matthew McGee
Adaptive radiations are generally thought to occur soon after a lineage invades a region offering high levels of ecological opportunity. However, few adaptive radiations beyond a handful of exceptional examples are known, so a comprehensive understanding of their dynamics is still lacking. Here, we present a novel case of an island species flock of freshwater fishes with a radically different tempo of adaptive history than that found in many popular evolutionary model systems. Using a...

Chatham Islands cabled observatory science opportunities: workshop 23–24 February 2021 summary report

Laura M. Wallace, John Townend, Craig Stevens, Richard L. Kellett, Joao De Souza, Giacamo Giorli, Jess I. T. Hillman, Caroline Holden, Bruce Howe, Daniel Leduc, Nate Lindsay, Joshu J. Mountjoy, William L. Power & Emily Warren-Smith
Our ability to address many key questions regarding physical oceanography, plate boundary processes and marine biodiversity, and to undertake geohazards monitoring in the New Zealand region, is greatly hampered by the lack of access to real-time, continuous offshore monitoring of a range of key observables beneath our oceans, which comprises >95% of our Exclusive Economic Zone (EEZ). Developing the ability to monitor geological, biological and oceanographic processes within our EEZ is required to better understand...

Data from: Diversification dynamics of Cheilostome Bryozoa based on a Bayesian analysis of the fossil record

Farideh Moharrek, Paul Taylor, Daniele Silvestro, Helen Jenkins, Dennis Gordon & Andrea Waeschenbach
Cheilostomata is the most diverse and ecologically dominant order of bryozoans living today. We apply a Bayesian framework to estimate macroevolutionary rates of cheilostomes since the Late Jurassic across four datasets: I) manually curated genus ranges, II) published text-mined genus ranges, III) non-revised Paleobiology Database (PBDB) records, IV) revised and augmented PBDB records. All datasets revealed increased origination rates in the Albian, and a twin K-Pg and Danian extinction rate peak. High origination rates in...
