Global warming can affect all levels of biological complexity, though we currently understand least about its potential impact on communities and ecosystems. At the ecosystem level, has capacity to alter structure rates key processes they mediate. Here assessed effects a 4°C rise in temperature size taxonomic composition benthic aquatic mesocosms, detrital decomposition mediated. Warming had no effect biodiversity, but altered community two ways. In spring, warmer systems exhibited steeper...
Abstract Ecosystem respiration is a primary component of the carbon cycle and understanding mechanisms that determine its temperature dependence will be important for predicting how rates efflux might respond to global warming. We used rare model system, comprising network geothermally heated streams ranging in from 5 °C 25 °C, explore nature relationship between temperature. Using this ‘natural experiment’, we tested whether natal thermal regime stream communities influenced absence other...
Abstract Biodiversity loss is occurring rapidly worldwide, yet it uncertain whether few or many species are required to sustain ecosystem functioning in the face of environmental change. The importance biodiversity might be enhanced when multiple processes (termed multifunctionality) and contexts considered, no studies have quantified this explicitly date. We measured five key their combined multifunctionality at three temperatures (5, 10 15 °C) freshwater aquaria containing different animal...
Abstract Extensive habitat destruction and pollution have caused dramatic declines in aquatic biodiversity at local to global scales. In rivers, the reintroduction of large woody debris is a common method aimed restoring degraded ecosystems through “rewilding.” However, causal evidence for its effectiveness lacking due dearth replicated before–after control‐impact field experiments. We conducted first experiment rewilding across multiple rivers organisational levels, from individual target...
Understanding how ecological communities are structured and this may vary between different types of ecosystems is a fundamental question in ecology. We develop general framework for quantifying size‐structure within among ecosystem (e.g. terrestrial, freshwater or marine), via the use suite bivariate relationships organismal size properties individuals, populations, assemblages, pair‐wise interactions, network topology. Each these can be considered dimension size‐structure, along which real...
Land-use and land-cover transitions can affect biodiversity ecosystem functioning in a myriad of ways, including how energy is transferred within food-webs. Size spectra (i.e. relationships between body size biomass or abundance) provide means to assess food-webs respond environmental stressors by depicting from small larger organisms. Here, we investigated changes the spectrum aquatic macroinvertebrates along broad land-use intensification gradient (from Atlantic Forest mechanized...
Abstract The ratio of predator-to-prey biomass is a key element trophic structure that typically investigated from food chain perspective, ignoring channels energy transfer (e.g. omnivory) may govern community structure. Here, we address this shortcoming by characterising the 141 freshwater, marine and terrestrial webs, spanning broad gradient in biomass. We test whether sub-linear scaling between predator prey (a potential signal density-dependent processes) emerges within ecosystem types...
1. Numerous studies have revealed (usually positive) relationships between biodiversity and ecosystem functioning (B-EF), but the underpinning drivers are rarely addressed explicitly, hindering development of a more predictive understanding. 2. We developed suite statistical models (where we combined existing with novel ones) to test for richness evenness effects on detrital processing in freshwater microcosms. Instead using consumer species as units, used two size classes within three (six...
Food webs are important tools for understanding how complex natural communities structured and they respond to environmental change. However their full potential has yet be realised because of the huge amount resources required construct them de novo. Consequently, current catalogue networks that suitable rigorous comparative analyses theoretical development still suffers from a lack standardisation replication. Here, we present novel R function, WebBuilder, which automates construction food...
<title>Abstract</title> Organism body size influences ecosystem services, and human pressures alter the structure of ecological communities. Our understanding how different human-induced (such as land-use biotic invasion) interact to drive community services remains limited. Combining 21 years fish spectrum data fishery potential (fishery monetary value), we demonstrate that exponent native species became more negative over time, indicating a relative decrease in biomass large versus small...
Microplastic particles (MPs) have been identified as potentially harmful to groundwater ecosystems. They can enter aquifers through recharge water passing the vadose zone, groundwater-surface interactions, wells and boreholes at supply managed aquifer sites or were river wastewater is extensively filtered subsurface sediments. While first studies MP contamination in groundwater, a clear picture of global concentrations still missing. However, such baseline information required understand...
Abstract Body size is a key trait in ecology due to its influence on metabolism and many other life‐history traits that affect population community responses environmental variation as well ecosystem properties. The spectrum represents the relationship between abundance (or biomass) body size, independent of species identity. Size parameters, such slope or intercept, have been applied extensively indicators ecological status across multiple types. GLOSSAQUA dataset includes data from mainly...
