There is an urgent need to understand species and community responses climatic ecological changes predict biodiversity patterns given anticipated global change. The current distribution of the environment provide a limited perspective study responses; therefore, past environmental must be examined. rapid development niche models (ENMs) their use in reconstructing distributions has facilitated inclusion observations into predictive models. Paleodata offer opportunity test ability ENMs...
Abstract Aim Quaternary palaeopalynological records collected throughout the Iberian Peninsula and species distribution models (SDMs) were integrated to gain a better understanding of historical biogeography Abies (i.e. pinsapo alba ). We hypothesize that SDMs palaeorecords are closely correlated, assuming certain stasis in climatic topographic ecological niche dimensions. In addition, modelling results used assign fossil A. or , identify environmental variables affecting their distribution,...
Abstract Aim Emerging polyploids may depend on environmental niche shifts for successful establishment. Using the alpine plant Ranunculus kuepferi as a model system, we explore shift hypothesis at different spatial resolutions and in contrasting parts of species range. Location European Alps. Methods We sampled 12 individuals from each 102 populations R. across Alps, determined their ploidy levels, derived coarse‐grain (100 × 100 m) descriptors all sampling sites by downscaling WorldClim...
Species distribution models (SDMs) assume species exist in isolation and do not influence one another's distributions, thus potentially limiting their ability to predict biodiversity patterns. Community-level (CLMs) capitalize on co-occurrences fit shared environmental responses of communities, therefore may result more robust transferable models. Here, we conduct a controlled comparison five paired SDMs CLMs across changing climates, using palaeoclimatic simulations fossil-pollen records...
Future climates are projected to be highly novel relative recent climates. Climate novelty challenges models that correlate ecological patterns climate variables and then use these relationships forecast responses future change. Here, we quantify the magnitude significance of by comparing it over past 21,000 years in North America. We between model performance derived from fossil pollen record eastern America estimate expected decrease predictive skill forecasting as increases. show that,...
Abstract Community‐level models (CLMs) consider multiple, co‐occurring species in model fitting and are lesser known alternatives to distribution (SDMs) for analysing predicting biodiversity patterns. simultaneously multiple species, including rare while reducing overfitting implicitly considering drivers of co‐occurrence. Many CLMs direct extensions well‐known SDMs therefore should be familiar ecologists. However, remain underutilized, there have been few tests their potential benefits no...
The role of competition for light among plants has long been recognised at local scales, but its importance plant species distributions larger spatial scales generally ignored. Tree cover modifies the abiotic conditions below canopy, notably by reducing availability, and thus, also performance that are not adapted to low-light conditions. However, this effect may propagate coarser grains, affecting colonisation probabilities extinction risks herbs shrubs. To assess tree both plot-...
Abstract Asexual taxa often have larger ranges than their sexual progenitors, particularly in areas affected by Pleistocene glaciations. The reasons given for this ‘geographical parthenogenesis’ are contentious, with expansion of the ecological niche or colonisation advantages uniparental reproduction assumed most important case plants. Here, we parameterized a spread model alpine buttercup Ranunculus kuepferi and reconstructed joint Holocene range its apomictic cytotype across European Alps...

Summary Background In recent years, it has been demonstrated that the air carries not only airborne pollen but also plant particles of smaller size have allergenic activity, and, being within respirable range, these can trigger rapid attacks in lower respiratory tract. The study according to (0.7–40 μm) could provide valuable information on real activity atmosphere. Objective purpose this was analyse dynamics Olea europaea contrast Ole e 1 Methods analyses were carried out with a Hirst‐type...
Abstract Anthropogenic pressures are causing a global decline in biodiversity. Successful attempts at biodiversity conservation requires an understanding of patterns as well the drivers and processes that determine those patterns. To deepen this knowledge, neoecologists have focused on studying present-day or recent historical data, while paleoecologists usually study long-term data through composition various biological proxies environmental indicators. By establishing standard protocols...
Persistence of relict tree species in Mediterranean environments is becoming increasingly unlikely view ongoing and future global change. The variability the Holocene climate more recent anthropogenic impacts have driven many populations to fragmentation isolation, even extinction. However, some persisted present day. understanding their evolution requires long-term studies, which pollen analysis a key approach both for formulating hypotheses supporting results from other disciplines....
Abstract Questions North African dry woodlands constitute mediterranean climatic ecotone ecosystems of vital importance for human livelihoods and local biodiversity. To improve the basis managing these key ecosystems, we selected a Tertiary relict woodland ( Argania spinosa ) in order to clarify sensitivity long‐term climate change (the present, past glacial‐interglacial cycle under future scenarios). We also discuss impact land use distribution Africa. Location Methods assess whether argan...
Abstract Aim Fossil records are being increasingly used to help understand the consequences of climate change for biodiversity. Pollen from late Q uaternary among most commonly fossil data, but pollen‐based inferences biodiversity can potentially be confounded by spatial and taxonomic uncertainties influence non‐climatic abiotic factors such as soils on vegetation–climate relationships. Using paired pollen vegetation inventories, we assess fidelity estimates compositional turnover along...
