Abstract Aims The 50th anniversary of the publication seminal book, Theory Island Biogeography , by Robert H. MacArthur and Edward O. Wilson, is a timely moment to review identify key research foci that could advance island biology. Here, we take collaborative horizon‐scanning approach 50 fundamental questions for continued development field. Location Worldwide. Methods We adapted well‐established methodology horizon scanning priority in biology, initiated it during Biology 2016 conference...
Islands are among the last regions on Earth settled and transformed by human activities, they provide replicated model systems for analysis of how people affect ecological functions. By analyzing 27 representative fossil pollen sequences encompassing past 5000 years from islands globally, we quantified rates vegetation compositional change before after arrival. After arrival, turnover accelerate a median factor 11, with faster colonized in 1500 than those earlier. This global anthropogenic...
Significance We use a diverse set of lake and landscape proxy indicators to characterize initial human occupation its impacts on the Azores Archipelago. The these islands began between 700 850 CE, years earlier than suggested by documentary sources. These early occupations caused widespread ecological disturbance raise doubts about islands' presumed pristine nature during Portuguese arrival. earliest explorers arrived at end Middle Ages, when temperatures were higher average, westerly winds...
South American seasonally dry tropical forests (SDTFs) are critically endangered, with only a small proportion of their original distribution remaining. This paper presents 12 000 year reconstruction climate change, fire and vegetation dynamics in the Bolivian Chiquitano SDTF, based upon pollen charcoal analysis, to examine resilience this ecosystem drought fire. Our analysis demonstrates complex relationship between climate, floristic composition over multi-millennial time scales, reveals...
A multiproxy approach was applied to a sediment core retrieved from the deep crater Lake Funda, located in middle of North Atlantic Ocean on Flores Island, Azores archipelago (Portugal). The purpose this study determine how ecosystem responded natural and anthropogenic forces over last millennium. We distinguished three main phases lake evolution using reconstructions documentary sources. (A) Climate catchment processes, as well internal ones, were drivers variability before 1335 CE, when...
Analyses of pollen, diatoms, XRF geochemistry, and pigments provide a unique window into how an insular ecosystem in Mauritius responded to extreme drought event 4200 years ago. We reconstruction regional vegetation change local wetland development under influence sea level rise inferred climate between 4400 4100 cal. yr BP. Our multi-proxy data evidence severe 4190 4130 BP, which ultimately led mass mortality larger vertebrates, including two species giant tortoises dodos <2-ha region....
Abstract Fire was rare on Mauritius prior to human arrival ( AD 1598); subsequently three phases of elevated fire activity occurred: ca 1630–1747, 1787–1833, and 1950–modern. Elevated frequency coincided with periods high impact evidenced from the historical record, is linked extinction island endemics.
Abstract A 10 m long peat core from the Kanaka Crater (20° 25′ S, 57° 31′ E), located at 560 elevation in Mauritius, was analyzed for microfossils. Eight radiocarbon ages show pollen record reflects environmental and climatic change of last ca. 38 cal ka BP. The shows that island continuously covered by forest with Erica heath ( Philippia ) uplands. Cyperaceous reedswamp Pandanus trees abundant coastal lowlands as well locally waterlogged crater. changes humidity (wet 38.0 to 22.7 BP, drier...
Abstract How do organisms arrive on isolated islands, and how insular evolutionary radiations arise? In a recent paper, Wilmé et al . ( ) argue that early Austronesians colonized Madagascar from Southeast Asia translocated giant tortoises to islands in the western Indian Ocean. Mascarene Islands, moreover, human‐translocated then evolved radiated an endemic genus Cylindraspis ). Their proposal ignores broad, established understanding of processes leading formation native island biotas,...
Paleoclimatological information derived from the study of lacustrine sedimentary records is not only biased by taphonomical processes but also potential differences in expression climate variability sediments due to site-specific factors. Using a multiproxy approach (the elemental and isotopic compositions organic matter, diatom assemblages, marker pigments algae cyanobacteria), we different environmental signatures recorded since Little Ice Age (LIA) two volcanic lakes located within same...
Abstract Human activity has fundamentally altered wildfire on Earth, creating serious consequences for human health, global biodiversity, and climate change. However, it remains difficult to predict fire interactions with land use, management, change, representing a knowledge gap vulnerability. We used expert assessment combine opinions about past future regimes from 98 researchers. asked quantitative qualitative assessments of the frequency, type, implications regime change beginning...
Abstract A new fossil site in a previously unexplored part of western Madagascar (the Beanka Protected Area) has yielded remains many recently extinct vertebrates, including giant lemurs ( Babakotia radofilai , Palaeopropithecus kelyus Pachylemur sp., and Archaeolemur edwardsi ), carnivores Cryptoprocta spelea the aardvark-like Plesiorycteropus ground cuckoos Coua ). Many these represent considerable range extensions. Extant species that were extirpated from region (e.g., Prolemur simus )...
