Phytoplankton blooms structure primary production and food‐web dynamics in the Gulf of Alaska, yet their response to recent warming and marine heatwaves (MHWs) remains poorly described. Using a parametric Gaussian framework applied to 21 years of satellite chlorophyll a (Chl a ), this study classified daily Chl a timeseries into double‐bloom, single spring‐bloom, single fall‐bloom, and no‐bloom regimes and related these to lar...

Rationale There is increasing interest in establishing psychedelic research programs at academic medical centers. However, psychedelics are intensely psychoactive, carry considerable sociopolitical baggage, and most are Schedule I drugs, creating significant potential impediments to implementation. There is little formal guidance for investigators on navigating the complex on-the-ground obstacles associated with establishing p...

Located at the confluence of the Arctic and North Pacific and with Alaska at its heart, the Pacific Arctic Region (PAR) is a unique and interconnected regional climate system. Significant climatic changes in the PAR are described by a novel, mobile monthly Alaska Arctic Front (AAF) index, which is defined by sea level pressure differences between the migratory cores of the Beaufort High and Aleutian Low. Regional climate varia...

Genetic structure in host species is often used to predict disease spread. However, host and pathogen genetic variation may be incongruent. Understanding landscape factors that have either concordant or divergent influence on host and pathogen genetic structure is crucial for wildlife disease management. Devil facial tumour disease (DFTD) was first observed in 1996 and has spread throughout almost the entire Tasmanian devil ge...

Identifying the genetic architecture of complex phenotypes is a central goal of modern biology, particularly for disease‐related traits. Genome‐wide association methods are a classical approach for identifying the genomic basis of variation in disease phenotypes, but such analyses are particularly challenging in natural populations due to sample size difficulties. Extensive mark–recapture data, strong linkage disequilibrium an...

Aim Determining which species are more prone to extinction is vital for conserving E arth's biodiversity and for providing insight into macroevolutionary processes. This paper utilizes the Pliocene to Recent fossil record of mollusks to identify determinants of species' extinction over the past three million years of E arth history. Location W estern A tlantic. Methods We focus on 92 bivalve and gastropod species that lived du...

Large‐mammal herbivore populations are subject to the interaction of internal density‐dependent processes and external environmental stochasticity. We disentangle these processes by linking consumer population dynamics, in a highly stochastic environment, to the availability of their key forage resource via effects on body condition and subsequent fecundity and mortality rates. Body condition and demographic rate data were obt...

We assembled data from a global network of automated lake observatories to test hypotheses regarding the drivers of ecosystem metabolism. We estimated daily rates of respiration and gross primary production (GPP) for up to a full year in each lake, via maximum likelihood fits of a free‐water metabolism model to continuous high‐frequency measurements of dissolved oxygen concentrations. Uncertainties were determined by a bootstr...

Variable morphological characters have obscured genealogical relationships in the Cape fossorial skink Acontias meleagris meleagris species complex. Currently the species complex contains four dubious operational taxonomic units ( A. meleagris meleagris , A. m. orientalis , A. percivali tasmani and the morph lineicauda) with poorly defined species boundaries. In the present study we examine the evolutionary relationships withi...

Data of ice cover for deep Alpine lakes contain relevant climatological information since ice cover and winter temperature are closely related. For the first time, ice cover data from 11 lakes on the Swiss plateau have been collected and analysed for the period 1901–2006. The ice cover data used stem from systematic registration by individuals or groups (fishermen, an ice club and lake security service) and from several nation...
