The emergence and promise of functional biogeography

Proceedings of the National Academy of Sciences, Год журнала: 2014, Номер 111(38), С. 13690 - 13696

Understanding, modeling, and predicting the impact of global change on ecosystem functioning across biogeographical gradients can benefit from enhanced capacity to represent biota as a continuous distribution traits. However, this is challenge for field biogeography historically grounded species concept. Here we focus newly emergent functional biogeography: study geographic trait diversity organizational levels. We show how bridges species-based earth science provide ideas tools help explain in multifaceted (including species, functional, phylogenetic diversities), predict services worldwide, infuse regional conservation programs with basis. Although much recent progress has been made possible because rising multiple data streams, new developments ecoinformatics, methodological advances, future directions should theoretical comprehensive framework scaling biotic interactions trophic levels its ecological implications.

Human alteration of natural light cycles: causes and ecological consequences

Oecologia, Год журнала: 2014, Номер 176(4), С. 917 - 931

Artificial light at night is profoundly altering natural cycles, particularly as perceived by many organisms, over extensive areas of the globe. This alteration comprises introduction places and times which it has not previously occurred, with different spectral signatures. Given long geological periods for cycles have been consistent, this constitutes a novel environmental pressure, one there evidence biological effects that span from molecular to community level. Here we provide synthesis understanding form extent alteration, some key consequences terrestrial aquatic ecosystems, interactions synergies other anthropogenic pressures on environment, major uncertainties, future prospects management options. compelling example need thoroughly interdisciplinary approach managing impact particular pressure. The former requires insights biology ecosystem ecology, latter contributions biologists, policy makers engineers.

Climate-driven changes in functional biogeography of Arctic marine fish communities

Proceedings of the National Academy of Sciences, Год журнала: 2017, Номер 114(46), С. 12202 - 12207

Опубликована: Окт. 31, 2017

Significance Arctic marine ecosystems are experiencing a rapid biogeographic change following the highest warming rates observed around globe in recent decades. Currently, there no studies of how shifts species composition affecting ecosystem functioning at scale. We address this issue via functional biogeography and show that increasing temperatures reduced ice coverage associated with borealization fish communities. find large body-sized piscivorous semipelagic boreal replacing small-bodied benthivorous species, likely biomass production benthic pelagic compartments their coupling. The documented speed magnitude climate-driven will profoundly alter Arctic.

Two sides of a coin: ecological and chronobiological perspectives of timing in the wild

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2017, Номер 372(1734), С. 20160246 - 20160246

Most processes within organisms, and most interactions between organisms their environment, have distinct time profiles. The temporal coordination of such is crucial across levels biological organization, but disciplines differ widely in approaches to study timing. Such differences are accentuated ecologists, who centrally concerned with a holistic view an organism relation its external chronobiologists, emphasize internal timekeeping the mechanisms adjustment environment. We argue that ecological chronobiological perspectives complementary, studies at intersection will enable both fields jointly overcome obstacles currently hinder progress. However, achieve this integration, we first cross some conceptual barriers, clarifying prohibitively inaccessible terminologies. critically assess main assumptions concepts either field, as well common interests. Both intersect need understand extent regulation plasticity, concept 'chronotype', i.e. characteristic properties individuals which targets natural sexual selection. then highlight promising developments, point out open questions, acknowledge difficulties propose directions for further integration through Wild Clock research.This article part themed issue 'Wild Clocks: integrating chronobiology ecology free-living animals'.

Global variation in diurnal asymmetry in temperature, cloud cover, specific humidity and precipitation and its association with leaf area index

Global Change Biology, Год журнала: 2020, Номер 26(12), С. 7099 - 7111

Опубликована: Сен. 30, 2020

Abstract The impacts of the changing climate on biological world vary across latitudes, habitats and spatial scales. By contrast, time day at which these changes are occurring has received relatively little attention. As biologically significant organismal activities often occur particular times day, any asymmetry in rate change between daytime night‐time will skew climatic pressures placed them, this could have profound natural world. Here we determine global variation difference mean annual near‐surface maximum minimum temperatures cloud cover, specific humidity precipitation changed over land. For years 1983–2017, derived hourly data assigned each hour as during daylight or darkness. In regions that showed warming >0.5°C (equivalent to surface temperature 20th century) investigated corresponding precipitation. We then examined proportional leaf area index (LAI) one potential response diel asymmetry. demonstrate where increased by more than temperatures, increased. Conversely, decreased.

Time and ecological resilience: can diurnal animals compensate for climate change by shifting to nocturnal activity?

Ecological Monographs, Год журнала: 2018, Номер 89(1)

Опубликована: Ноя. 12, 2018

Abstract Considerable research is aimed at developing predictions of ecosystem responses to climate change, focusing on the spatial scale, such as range shifts and contractions, well activity restrictions shaded microhabitats. On other hand, ability species shift their times during diel cycle, consequently alter environment in which occurs, has been largely neglected. Daily patterns are perceived fairly fixed; however, natural changes have reported increasing numbers species. Here, we present a framework that explores how may buffer impacts change. To demonstrate our framework, simulated costs diurnal nocturnal rodents showed future summers decrease energetic demands mammals while water mammals. Climate projections suggest vegetation cover availability will under scenarios, especially areas where expected increase most. These limit animals restrict microhabitats keep positive balance. Our analysis shows by shifting nocturnality, mitigate high summers. We should explore role time axis an ecological resource when predicting
