A detailed record of the Late Holocene sea level rise and landscape evolution that has taken place on the Georgia coast is contained within the sedimentary stratigraphy of its salt marsh depositional basins. Global relative sea level (RSL) has risen during the Late Holocene, and the rate of rise has accelerated during the Anthropocene. Jones Narrows marsh stratigraphy and radiocarbon analysis i...

Several highly effective fire-adaptive traits first evolved among modern plants during the mid-Cretaceous, in response to the widespread wildfires promoted by anomalously high atmospheric oxygen (O2) and extreme temperatures. Serotiny, or long-term canopy seed storage, is a fire-adaptive strategy common among plants living in fire-prone areas today, but evidence of this strategy has been lackin...

Interest in addressing antimicrobial resistance (AMR) has grown recently but little effort has been made to consider how existing and new vaccines could impact on AMR. A 2017 Chatham House meeting considered the role of vaccines and how to demonstrate their value through their impact on AMR. Ways existing vaccines have reduced antibiotic prescribing and the prevalence of some resistant organism...

The Kean–Barlow model predicts how the equilibrium distribution and abundance of a population may be affected by local rates of increase, dispersal, colonisation, and extinction. Here, the model is parameterised for three insects: the Glanville fritillary Melitaea cinxia in Åland, Finland, the ribbonwood aphid Paradoxaphis plagianthi in Christchurch, New Zealand, and the coxella weevil Hadramph...

This paper shows how to recursively calculate analytic first and second derivatives of the likelihood function generated by a popular version of a discrete-choice, dynamic programming model, allowing for a dramatic decrease in computing time used by derivative-based estimation algorithms. The derivatives also are very useful for finding the exact maximum of the likelihood function, for de-buggi...

Lejeunea hodgsoniana Grolle ex R.J.Lewington, P.Beveridge & M.A.M.Renner sp. nov., A taxon originally recognised by Riclef Grolle in 1980, but not described, known from a number of coastal sites in the North Island, the northern extremity of the South Island, the Kermadec Islands, and the Chatham Islands of New Zealand, is described and illustrated. The species is distinctive amongst species of...

The Subtropical Front (STF) and associated biological productivity are topographically locked to the Chatham Rise. Year-to-year differences of upper ocean dynamics responses phytoplankton valuable for understanding variability in fisheries biomass as well providing new knowledge environmental condition potential seabed mining this keystone ecosystem. In-situ observations collected over three co...
