Abstract One of the most common descriptors relationship between root and shoot biomass is : ratio, which has become a core method for estimating from more easily measured biomass. Previous reviews have examined ratio data, but only considered particular vegetation types not always critically reviewed data used. Reliable ratios are needed wide range in order to improve accuracy estimates, including those required effects land management use change National Greenhouse Gas Inventories. This...
Summary Experimental studies have provided significant knowledge of how biodiversity can influence ecosystem processes. However, there is a growing need to relate these findings natural communities. Here we identify two major hypotheses for communities may processes: the ‘diversity hypothesis’ (the diversity organisms in community influences processes through mechanisms such as complementary resource use), and ‘mass ratio (ecosystem are determined overwhelmingly by functional traits dominant...
Abstract Based on the sensitivity of species to ongoing climate change, and numerous challenges they face tracking suitable conditions, there is growing interest in species' capacity adapt climatic stress. Here, we develop apply a new generic modelling approach ( AdaptR ) that incorporates adaptive through physiological limits, phenotypic plasticity, evolutionary adaptation dispersal into distribution framework. Using predict change 17 Australian fruit flies (Drosophilidae), show accounting...
Understanding how plants are constructed—i.e., key size dimensions and the amount of mass invested in different tissues varies among individuals—is essential for modeling plant growth, carbon stocks, energy fluxes terrestrial biosphere. Allocation patterns can differ through ontogeny, but also coexisting species adapted to environments. While a variety models dealing with biomass allocation exist, we lack synthetic understanding underlying processes. This is partly due suitable data sets...
Abstract Aim Generalized dissimilarity modelling (GDM) is a powerful and unique method for characterizing predicting beta diversity, the change in biodiversity over space, time environmental gradients. The number of studies applying GDM expanding, with increasing recognition its value improving our understanding drivers patterns implementing wide variety spatial assessments relevant to conservation. However, apart from original presentation technique, there has been little guidance available...
Abstract Aim More than ever, ecologists seek to understand how species are distributed and have assembled into communities using the “filtering framework”. This framework is based on hypothesis that local assemblages result from a series of abiotic biotic filters applied regional pools these leave predictable signals in observed diversity patterns. In theory, statistical comparisons expected patterns enable data‐driven tests assembly processes. However, so far this has fallen short...
Abstract Aim Robust and reliable predictions of the effects climate change on biodiversity are required in formulating conservation management strategies that best retain into future. Significant challenges modelling impacts arise from limitations our current knowledge biodiversity. Community‐level can complement species‐level approaches overcoming these predicting as a whole. However, community‐level applied to date have been largely correlative, ignoring key processes influence over space...
Abstract Aim Species distribution models ( SDM s) generally use correlative relationships between the species location and associated environment to project potential under climate change. While projecting a future suitable climatic space is relatively simple using s, predicting ability occupy that relies on understanding dispersal capacity; lack of knowledge about species‐specific ability, varying geographical contexts technical constraints s has limited consideration in most studies. We...
Degradation and loss of natural habitat is the major driver current global biodiversity crisis. Most conservation efforts to date have targeted small areas highly threatened habitat, but emerging debate suggests that retaining large intact systems may be just as important. We reconcile these perspectives by integrating fine-resolution data on condition species assemblage turnover identify Earth’s high-value habitat. These are in better than most other locations predicted once supported a...
Abstract Aim Our ability to understand how species may respond changing climate conditions is hampered by a lack of high‐quality data on the adaptive capacity species. Plant functional traits are linked many aspects life history and adaptation environment, with different combinations trait values reflecting alternate strategies for adapting varied conditions. If realized limits can be partially explained plant combinations, then new approach using predict expected offer considerable...
The diversity of terrestrial vascular plants plays a key role in maintaining the stability and productivity ecosystems. Monitoring species compositional across large spatial scales is challenging time consuming. Airborne hyperspectral imaging has shown promise for measuring plant remotely, but to operationalise these efforts over regions we need advance satellite-based alternatives. advanced spectral specification recently launched DESIS (the DLR Earth Sensing Imaging Spectrometer)...
Reliable projections of climate-change impacts on biodiversity are vital in formulating conservation and management strategies that best retain into the future. While recent modelling has focussed largely individual species, macroecology potential to add significant value these efforts, by incorporating important community-level constraints processes. Here we show how a new dynamic macroecological approach can project collectively across all species diverse taxonomic group, overcoming...
Abstract Questions The taxonomic and functional composition of plant communities captures different dimensions diversity. Functional diversity (FD) — as calculated from species traits typically increases with richness in is expected to be higher less extreme environments, where a broader range strategies can persist. Further, woody herbaceous families may contribute disproportionately FD bioregions. To build an understanding these questions using Australia case study, we aimed quantify how...
Abstract Question: The quantification of functional traits in natural communities can be difficult (e.g. root traits, RGR). Can measured on pot grown plants reliably applied to communities? Alternatively, below‐ground plant predicted from above‐ground traits? Location: Southeastern Australia. Methods: We compared 17 shoot, and whole‐plant morphological 14 species a native grassland community those under two different conditions: unfertilised fertilised. Results: majority trait values for...
For many taxonomic groups, sparse information on the spatial distribution of biodiversity limits our capacity to answer a variety theoretical and applied ecological questions. Modelling community-level attributes (α- β-diversity) over space can help overcome this shortfall in knowledge, yet individually, predictions α- or β-diversity have their limitations. In study, we present novel approach combining models β-diversity, with survey data, predict community composition for all sites region....
Biodiversity analyses across continental extents are important in providing comprehensive information on patterns and likely drivers of diversity. For vascular plants Australia, community‐level diversity have been restricted by the lack a consistent plot‐based survey dataset continent. To overcome these challenges, we collated harmonised vegetation data from major sources Australia used them as basis for modelling species richness (α‐diversity) community compositional dissimilarity...
There is increasing reliance on ecological models to improve our understanding of how systems work, project likely outcomes under alternative global change scenarios and help develop robust management strategies. Two common types spatiotemporally explicit are those focussed biodiversity composition ecosystem function. These modelling disciplines largely practiced separately, with separate literature, despite growing evidence that natural shaped by the interaction Here we call for development...
