Data from: Changes in the location of biodiversity–ecosystem function hot spots across the seafloor landscape with increasing sediment nutrient loadingSimon F. Thrush, Judi E. Hewitt, Casper Kraan, A. M. Lohrer, Conrad A. Pilditch & Emily Douglas
Declining biodiversity and loss of ecosystem function threatens the ability of habitats to contribute ecosystem services. However, the form of the relationship between biodiversity and ecosystem function (BEF) and how relationships change with environmental change is poorly understood. This limits our ability to predict the consequences of biodiversity loss on ecosystem function, particularly in real-world marine ecosystems that are species rich, and where multiple ecosystem functions are represented by multiple indicators. We investigated spatial variation...
Data from: Population genetic structure and connectivity of deep-sea stony corals (Order Scleractinia) in the New Zealand region: implications for the conservation and management of Vulnerable Marine EcosystemsCong Zeng, Ashley A. Rowden, Malcolm R. Clark, Jonathan P.A. Gardner & Jonathan P. A. Gardner
Deep-sea stony corals, which can be fragile, long-lived, late to mature and habitat-forming, are defined as vulnerable marine ecosystem indicator taxa. Under United Nations resolutions these corals require protection from human disturbance such as fishing. To better understand the vulnerability of stony corals (Goniocorella dumosa, Madrepora oculata, Solenosmilia variabilis) to disturbance within the New Zealand region, and to guide marine protected area design, genetic structure and connectivity were determined using microsatellite loci and DNA sequencing....
Data from: Template for using biological trait groupings when exploring large-scale variation in seafloor multifunctionalityAnna Villnäs, Judi Hewitt, Martin Snickars, Mats Westerbom & Alf Norkko
Understanding large-scale spatial variation in ecosystem properties and associated functionality is key for successful conservation of ecosystems. This study provides a template for how to estimate differences in ecosystem functionality over large spatial scales by using groupings of biological traits. We focus on trait groupings that describe three important benthic ecosystem properties, namely bioturbation, community stability and juvenile dispersal. Recognizing that groups of traits interact and are constrained within an organism, we statistically define important...
Data from: The scaling of population persistence with carrying capacity does not asymptote in populations of a fish experiencing extreme climate variabilityRichard S.A. White, Brendan A. Wintle, Peter A. McHugh, Douglas J. Booker, Angus R. McIntosh & Richard S. A. White
Despite growing concerns regarding increasing frequency of extreme climate events and declining population sizes, the influence of environmental stochasticity on the relationship between population carrying capacity and time-to-extinction has received little empirical attention. While time-to-extinction increases exponentially with carrying capacity in constant environments, theoretical models suggest increasing environmental stochasticity causes asymptotic scaling, thus making minimum viable carrying capacity vastly uncertain in variable environments. Using empirical estimates of environmental stochasticity in fish metapopulations, we showed that...
Aims: Aerially applied glyphosate is an economic tool to deal with large areas of invasive plants. However, there are few studies investigating non-target effects or rates of reinvasion, particularly over multi-year timeframes. The aims were to evaluate the effectiveness of aerial application of glyphosate for control of dense stands of the invasive grey willow Salix cinerea, and determine the vegetation trajectory over the subsequent two years. Location: Whangamarino Wetland, Waikato, New Zealand. Methods: A before-after...
Data from: Phylogenetic distribution of a male pheromone that may exploit a nonsexual preference in lampreysTyler J. Buchinger, Ugo Bussy, Ke Li, Huiyong Wang, Mar Huertas, Cindy F. Baker, Liang Jia, Michael C. Hayes, Weiming Li & Nicholas S. Johnson
Pheromones are among the most important sexual signals used by organisms throughout the animal kingdom. However, few are identified in vertebrates, leaving the evolutionary mechanisms underlying vertebrate pheromones poorly understood. Pre-existing biases in receivers’ perceptual systems shape visual and auditory signaling systems, but studies on how receiver biases influence the evolution of pheromone communication remain sparse. The lamprey Petromyzon marinus uses a relatively well-understood suite of pheromones and offers a unique opportunity to study the...
Data from: Long-term environmental monitoring for assessment of change: measurement inconsistencies over time and potential solutionsKari E. Ellingsen, Nigel G. Yoccoz, Torkild Tveraa, Judi E. Hewitt & Simon F. Thrush
The importance of long-term environmental monitoring and research for detecting and understanding changes in ecosystems and human impacts on natural systems is widely acknowledged. Over the last decades a number of critical components for successful long-term monitoring have been identified. One basic component is quality assurance/quality control protocols to ensure consistency and comparability of data. In Norway, the authorities require environmental monitoring of the impacts of the offshore petroleum industry on the Norwegian continental shelf,...
