Some Like It Hot: Investigating Thermoregulatory Behavior of Carcharhinid Sharks in a Natural Environment with Artificially Elevated Temperatures

open access: yesFishes, 2023
Global warming raises seawater temperatures and creates changes which have been found to affect the movement of large migrating marine species. Understanding the thermal niches of marine species could prove essential to anticipate how the future climate ...

Range Mapper: An Adaptable Process for Making and Using Interactive, Animated Web Maps of Late-Quaternary Open Paleoecological Data

open access: yesOpen Quaternary, 2023
Here, we describe our process of developing Range Mapper, a new set of online interactive and animated visualizations of plant taxon range shifts since the Last Glacial Maximum. These animated maps of taxa distributions since the last deglaciation, based

Fine-scale survey of intertidal macroalgae reveals recent changes in a cold-water biogeographic stronghold

open access: yesFrontiers in Marine Science, 2022
Global warming has been causing severe impacts on marine ecosystems, a notorious one being shifts in the geographical ranges of species. The north-western coast of the Iberian Peninsula is an especially interesting zone to study distributional shifts as ...

Climate‐induced range shifts shaped the present and threaten the future genetic variability of a marine brown alga in the Northwest Pacific

open access: yesEvolutionary Applications, 2021
Glaciation‐induced environmental changes during the last glacial maximum (LGM) have strongly influenced species' distributions and genetic diversity patterns in the northern high latitudes.

Mutation load dynamics during environmentally-driven range shifts. [PDF]

open access: yesPLoS Genetics, 2018
The fitness of spatially expanding species has been shown to decrease over time and space, but specialist species tracking their changing environment and shifting their range accordingly have been little studied.

Usefulness of Species Traits in Predicting Range Shifts [PDF]

open access: yesTrends in Ecology & Evolution, 2016
Information on the ecological traits of species might improve predictions of climate-driven range shifts. However, the usefulness of traits is usually assumed rather than quantified. Here, we present a framework to identify the most informative traits, based on four key range-shift processes: emigration of individuals or propagules away from the natal ...

Effects of Pleistocene climate changes on species ranges and evolutionary processes in the Neotropical Atlantic Forest [PDF]

open access: yes, 2016
The effects of global glaciations on the distribution of organisms is an essential element of many diversification models. However, the empirical evidence supporting this idea is mixed, in particular with respect to explaining tropical forest evolution ...

The numerical range of a weighted shift [PDF]

open access: yesProceedings of the American Mathematical Society, 1983
Let T T be a weighted shift on a Hilbert space. We compute the numerical radius of T T when T T is finite, circular, Hilbert-Schmidt, periodic, or a finite perturbation of periodic. For several cases we also determine whether the numerical range is closed, completing the determination of the ...

Range shifting on a fragmented landscape

open access: yesEcological Informatics, 2007
Abstract Projected responses of species' to climate change have so far included few of the factors that are important determinants of species' distributions within its range. In this paper we utilise a spatially explicit cellular lattice, colonisation–extinction model to investigate the effect of habitat loss, fragmentation and species ...

Range extension for the region of sympatry between the nudibranchs Hermissenda opalescens and Hermissenda crassicornis in the northeastern Pacific

open access: yesFACETS, 2018
The mollusc nudibranch genus Hermissenda Bergh, 1879 was recently discovered to include three pseudocryptic species, dividing a single species H. crassicornis (sensu lato) into H. crassicornis Escholtz, 1831, H. opalescens J.G.
