Relationships in the Interbank Market

Jonathan Chiu & Cyril Monnet
In the interbank market for overnight loans, banks sometimes trade below the central bank's deposit rate. This act is puzzling, as it seems to miss exploiting opportunities for arbitrage. In particular, why do banks lend to other banks, exposing themselves to counterparty risk, when they could earn a higher rate by depositing the balances at a risk-free central bank? This paper provides a theory to explain this anomaly. In the presence of market frictions, banks...

Submarine Cables and the Oceans – Connecting the World

Lionel Carter, Douglas Burnett, Stephen Drew, Graham Marle, Lonnie Hagadorn, Deborah Bartlett-McNeil & Nigel Irvine
​UNEP-WCMC in collaboration with the International Cable Protection Committee and UNEP has prepared a new report which provides an objective, factual description of the sub-marine cable industry and the interaction of submarine telecommunications (which route 95% of all international communications traffic) with the marine environment. This important report seeks to focus and guide deliberations and decision making on the wise conservation and protection of the oceans in concert with their sustainable management and use.

New Zealand Fault-Rupture Depth Model v1.0: a provisional estimate of the maximum depth of seismic rupture on New Zealand’s active faults

Susan M. Ellis, Stephen Bannister, Russ J. Van Dissen, Donna Eberhart-Phillips, Caroline Holden, Carolyn Boulton, Martin E. Reyners, Robert H. Funnell, Nick Mortimer & Phaedra Upton
This report presents a new and provisional estimate of the maximum depth of rupture on New Zealand’s active faults (“New Zealand Fault-Rupture Depth Model v1.0”) based on a combination of two independent models. The first model uses regional seismicity distribution from a relocated earthquake catalogue to calculate the 90% seismicity cut-off depth (D90) representing the seismogenic depth limit H. This is multiplied by an overshoot factor representing dynamic propagation of rupture into the conditional stability...

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),...

Brown bear population vital rates

Michelle McLellan
Identifying mechanisms of population change is fundamental for conserving small and declining populations and determining effective management strategies. Few studies, however, have measured the demographic components of population change for small populations of mammals (< 50 individuals). We estimated vital rates and trends in two adjacent but genetically distinct, threatened brown bear (Ursus arctos) populations in British Columbia, Canada, following the cessation of hunting. One population had approximately 45 resident bears but had some genetic...

Rapid multi-generational acclimation of coralline algal reproductive structures to ocean acidification

Billy Moore, Steeve Comeau, Matthieu Bekaert, Amelie Cossias, Ashley Purdy, Ellis Larcombe, Frankie Puerzer, Malcolm McCulloch & Christopher Cornwall
The future of coral reef ecosystems is under threat because vital reef-accreting species such as coralline algae are highly susceptible to ocean acidification. Although ocean acidification is known to reduce coralline algal growth rates, its direct effects on the development of coralline algal reproductive structures (conceptacles) is largely unknown. Furthermore, the long-term, multi-generational response of coralline algae to ocean acidification is extremely understudied. Here, we investigate how mean pH, pH variability and the pH regime...

Repeated measure plant community data after fire in boreal forest, Taiga Shield, Northwest Territories, Canada, 1998-2018

Nicola Day, Jennifer Baltzer & Suzanne Carriere
10 transects were established in the years following fire in boreal forest stands on the Taiga Shield, Northwest Territories, Canada in 1998-1999. These were remeasured annually. Six transects were returned to on 2018 for another measurement. At each measurement, we recorded ground covers, species identities, and counted tree stems (seedlings).

Socio-economic and environmental impacts of ants: data to support global assessments

Monica Gruber, Davide Santoro, Meghan Cooling, Philip Lester, Benjamin Hoffmann, Christina Boser & Lori Lach
Risk assessments are fundamental to invasive species management and are underpinned by comprehensive characterization of invasive species impacts. Our understanding of the impacts of invasive species is growing constantly, and several recently developed frameworks offer the opportunity to systematically categorize environmental and socio-economic impacts of invasive species. Invasive ants are among the most widespread and damaging invaders. We provide a global, comprehensive assessment on the impacts of ants and propose a priority list of risk...

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 associated with: Going round the twist – An empirical analysis of shell coiling in helicospiral gastropods

Katie S. Collins, Roman Klapaukh, James S. Crampton, Michael F. Gazley, C. Ian Schipper, Anton Maksimenko & Benjamin R. Hines
The logarithmic helicospiral has been the most widely accepted model of regularly coiled mollusc form since it was proposed by Moseley (1838) and popularised by Thompson (1942) and Raup (1966). It is based on an explicit assumption that shells are isometric and grow exponentially, and an implicit assumption that the external form of the shell follows the internal shape, which implies that the parameters of the spiral could, theoretically, be reconstructed from the external whorl...

Hydrogen peroxide signaling mediates fertilization and post-fertilization development in the red alga Bostrychia moritziana

Eunyoung Shim, Ji Woong Lee, Hana Park, Giuseppe C. Zuccarello & Gwang Hoon Kim
Reactive oxygen species (ROS) signaling has a multitude of roles in cellular processes throughout biology. We hypothesized that red algal fertilization may offer an interesting model to study ROS-mediated signaling as the stages of fertilization are complex and unique. We microscopically localized ROS production and monitored the expression of three homologues of NADPH-oxidase in reproductive cells during fertilization. ROS were instantaneously produced by spermatia (sperm) when they attached to female trichogynes, diffused across the cell...
