Forecasts of ecological dynamics in changing environments are increasingly important, and available for a plethora variables, such as species abundance distribution, community structure ecosystem processes. There is, however, general absence knowledge about how far into the future, or other dimensions (space, temperature, phylogenetic distance), useful forecasts can be made, features systems relate to these distances. The forecast horizon is dimensional distance which made. Five case studies...
Whether or not communities of microbial eukaryotes are structured in the same way as bacteria is a general and poorly explored question ecology. Here, we investigated this set planktonic lake microbiotas Eastern Antarctica that represent natural community ecology experiment. Most analysed lakes emerged from sea during last 6000 years, giving rise to waterbodies originally contained marine subsequently evolved into habitats ranging freshwater hypersaline. We show habitat diversification has...
Summary Laboratory microcosm experiments using protists as model organisms have a long tradition and are widely used to investigate general concepts in population biology, community ecology evolutionary biology. Many variables of interest measured order study processes patterns at different spatiotemporal scales across all levels biological organization. This includes measurements body size, mobility or abundance, understand dynamics, dispersal behaviour ecosystem processes. Also, variety...
A bacterial community may be resistant to environmental disturbances if some of its species show metabolic flexibility and physiological tolerance the changing conditions. Alternatively, can change composition thereby potentially affect ecosystem processes. The impact disturbance on bacterioplankton communities was examined in continuous seawater cultures. Bacterial assemblages from geographically closely connected areas, Baltic Sea (salinity 7 high dissolved organic carbon [DOC]) Skagerrak...
Mate choice for major histocompatibility complex (MHC) compatibility has been found in several taxa, although rarely birds. MHC is a crucial component adaptive immunity and by choosing an MHC-dissimilar partner, heterozygosity potentially broad pathogen resistance maximized the offspring. The genotype influences odour cues preferences mammals fish hence olfactory-based mate can occur. We tested whether blue petrels, Halobaena caerulea , choose partners based on compatibility. This bird...
Understanding the origins of biodiversity has been an aspiration since days early naturalists. The immense complexity ecological, evolutionary, and spatial processes, however, made this goal elusive to day. Computer models serve progress in many scientific fields, but fields macroecology macroevolution, eco-evolutionary are comparatively less developed. We present a general, spatially explicit, engine with modular implementation that enables modeling multiple macroecological...
Abstract Aims Patterns of species richness, such as the remarkable biodiversity tropical regions, have been documented and studied for centuries. However, their underlying evolutionary ecological causes are still incompletely understood. A commonly stated paradigm in literature is that high richness some habitats directly caused by one three competing explanations: (1) greater time‐for‐speciation (earlier colonization), (2) more rapid diversification rates (faster speciation relative to...
The latitudinal diversity gradient (LDG) is one of Earth's most iconic biodiversity patterns and still the debated. Explanations for LDG are often categorized into three broad pathways in which created by (1) differential diversification rates, (2) carrying capacities (ecological limits), or (3) time to accumulate species across latitude. Support these has, however, been mostly verbally expressed. Here, we present a minimal model clarify essential assumptions explore sensitivity dynamics...
The phylogenetic structure and community composition were analysed in an existing data set of marine bacterioplankton communities to elucidate the evolutionary ecological processes dictating assembly. sampled from coastal waters at nine locations distributed worldwide examined through use comprehensive clone libraries 16S ribosomal RNA genes. analyses show that local are phylogenetically different each other a majority them clustered, i.e. species (operational taxonomic units) more related...
We review models of natural pest control assessing usability across agroecosystems.• Ecological complexity and context sensitivity impede correlation-based predictions.• A trade-off generality with realism hinders mechanistic modeling systems.• Similarities in causal relationships can inform contextually bound generalizations.• This framework will allow knowledge synthesis transfer less studied regions.
Abstract. Environmental gradients affect vegetation structure and ecosystem productivity. Along the northern Australia tropical transect (NATT), which transitions from moist conditions in north to arid south, composition are closely tied rainfall patterns. We hypothesise that biotic competition abiotic stress exhibit opposing patterns along NATT gradient aim disentangle these effects on Using a trait-based dynamic model, we simulated responses varying NATT. The model successfully spatial...
Organismal abundance tends to decline with increasing body size. Metabolic theory links this size structure energy use and productivity across levels of biological organization, predicting a size-abundance slope -0.75 that is invariant environments. We tested whether the relationship robust gradient protist species richness (1 6 species), temperature (15 25 C), time. Our results support expected for relationship, but we found interactive effects indicating not invariant. In high-richness...
The biogeography of speciation and what can be learned about the past mode from current sister species are recurrent problems in evolution. We used a trait- individual-based, eco-evolutionary model to simulate adaptive radiations recorded geographical overlap during after evolutionary branching (speciation). compared spatial among fully saturated community with at event. mean geographic varied continuously complete (sympatry) none (allopatry), depending on local regional environmental...
Abstract Control of crop pests by shifting host plant availability and natural enemy activity at landscape scales has great potential to enhance the sustainability agriculture. However, mainstreaming pest control requires improved understanding how its benefits can be realized across a variety agroecological contexts. Empirical studies suggest significant but highly variable responses land‐use change. Current ecological models are either too specific provide insight agroecosystems or generic...
Abstract Statistical techniques exist for inferring community assembly processes from patterns. Habitat filtering, competition, and biogeographical effects have, example, been inferred signals in phenotypic phylogenetic data. The usefulness of current inference is, however, debated as a mechanistic causal link between process pattern is often lacking, evolutionary trophic interactions are ignored. Here, we revisit the knowledge on across scales and, line with several reviews that have...
Much of life's diversity has arisen through ecological opportunity and adaptive radiations, but the mechanistic underpinning such diversification is not fully understood. Competition predation can affect contrasting theoretical empirical results show that they both promote interrupt diversification. A understanding link between microevolutionary processes macroevolutionary patterns thus needed, especially in trophic communities. Here, we use a trait-based eco-evolutionary model to...
The expected link between competitive exclusion and community trait overdispersion has been used to infer competition in local communities, clustering interpreted as habitat filtering. Such assembly process inference received criticism for ignoring trophic interactions, interactions might create similar patterns. While other theoretical studies have generally demonstrated the importance of predation coexistence, ours provides first quantitative demonstration such effects on inference, using...
Adaptive radiation is a major source of biodiversity but the way in which known components ecological opportunity, differentiation, and reproductive isolation underpin such patterns remains elusive. Much about evolution differentiation during single speciation events, exactly how those processes scale up to complete adaptive radiations less understood. Do we expect barriers between newly formed species before continues, or does proper formation occur much later, long after diversification?...
