This article investigates the latest developments in longevity-risk modelling, and explores key risk management challenges for both financial insurance industries. The discusses definitions that are crucial enhancement of way longevity is understood, providing a global view practical issues longevity-linked pension products have evolved concurrently with steady increase life expectancy since s. In addition, frames recent forthcoming expected to action industry-wide changes as more effective...
Marine hard-bottom communities are undergoing severe change under the influence of multiple drivers, notably climate change, extraction natural resources, pollution and eutrophication, habitat degradation, invasive species. Monitoring marine biodiversity in such habitats is, however, challenging as it typically involves expensive, non-standardized, often destructive sampling methods that limit its scalability. Differences monitoring approaches furthermore hinders inter-comparison among...
The lack of sexual attraction between individuals from different populations is a direct barrier to gene flow these populations. Here we focus on the evolution this class isolating mechanism, behavioural isolation, through empirical study two closely related species small marine isopods. males Jaera albifrons and J. praehirsuta similarly engage females in tactile courtship by brushing specific region female's back, but they do so with divergent sets specialised setae spines, female choice...
Abstract. Since the beginning of industrial revolution, atmospheric carbon dioxide (CO2) concentrations have risen steadily and induced a decrease averaged surface ocean pH by 0.1 units, corresponding to an increase in acidity about 30 %. In addition warming, acidification poses tremendous challenge some marine organisms, especially calcifiers. The need for long-term oceanic observations temperature is key element assess vulnerability communities ecosystems these pressures. Nearshore...
This paper examines the problem of ruin in classical compound binomial and Poisson risk models. Our primary purpose is to extend those models an exact formula derived by Picard & Lefèvre (1997 , Ph.

First, a standard method based on ballot theorem argument Seal-type provides initial (known) that...
A high proportion of the kelp Laminaria hyperborea production is exported from forests following seasonal storms or natural annual old blade loss. Transport drifting fragments can lead to temporary accumulations in benthic subtidal habitats. We investigated degradation processes L. a low sandy bottom ecosystem by setting up 6-month cage experiment simulate on seafloor. monitored temporal changes biomass, nutritional quality (C:N ratio), respiration, quantum efficiency photosystem II (F
Abstract Accurately quantifying primary productivity of marine macrophytes is essential to further understanding coastal ecosystem functioning and will allow its inclusion within models. Traditional quantification carbon standing stock biomass accumulation only rough estimates net production whereas incubations that measure photosynthesis in the laboratory lack realism underestimate true photosynthetic rates. We developed situ photorespirometry methods estimate Laminaria hyperborea ,...
This paper is concerned with the class of distributions, continuous or discrete, whose shape monotone finite integer order t . A characterization presented as a mixture minimum independent uniform distributions. Then, comparison -monotone distributions made using s -convex stochastic orders. link also pointed out an alternative approach to monotonicity based on stationary-excess operator. Finally, property exploited reinforce classical Markov and Lyapunov inequalities. The results are...
