Abstract Much research has focused on identifying species that are susceptible to extinction following ecosystem fragmentation, yet even those persist in fragmented habitats may have fundamentally different ecological roles than conspecifics unimpacted areas. Shifts trophic role induced by especially of abundant top predators, could transcendent impacts food web architecture and stability, as well function. Here we use a novel measure niche width, based stable isotope ratios, assess effects...
Abstract Many natural marine habitats are decreasing in extent despite global conservation and restoration efforts. In contrast, built structures, such as hardened shorelines, offshore energy aquaculture infrastructure, artificial reefs, increasing extent—and, some locations, represent over 80% of nearshore, structured habitat. When introduced into the seascape, structures inevitably interact with habitats, but these not typically designed to support systems. This approach often results...
On coral reefs, fishes can facilitate growth via nutrient excretion; however, as abundance declines, these nutrients may help increases in macroalgae. By combining surveys of reef communities with bioenergetics modeling, we showed that fish excretion supplied 25 times more nitrogen to forereefs the Florida Keys, USA, than all other biotic and abiotic sources combined. One apparent result was a positive relationship between macroalgal cover on reefs. Herbivore biomass also negative cover,...
Abstract Corals thrive in low nutrient environments and the conservation of these globally imperiled ecosystems is largely dependent on mitigating effects anthropogenic enrichment. However, to better understand implications nutrients requires a heightened understanding baseline dynamics within ecosystems. Here, we provide novel perspective coral reef by examining role fish communities supply storage nitrogen (N) phosphorus (P). We quantified fish‐mediated for 144 species modeled data onto...
Consumer-mediated nutrient supply is increasingly recognized as an important functional process in many ecosystems. Yet, experimentation at relevant spatial and temporal scales needed to fully integrate this bottom-up pathway into ecosystem models. Artificial reefs provide a unique approach explore the importance of consumer for function coastal marine environments. We used bioenergetics models estimate community-level by fishes, measures primary production, test hypothesis that consumers,...
Significance A fundamental dilemma in ecology is to reconcile the degree which ecological processes are generalizable among taxa and ecosystems or determined primarily by taxonomic identity. We apply a unique dataset of organisms from diverse marine community test applicability two theories, metabolic theory (MTE) stoichiometry (EST), role identity for predicting nutrient excretion rates fishes macroinvertebrates. Excretion were principally explained body mass identity, providing strong...
Summary In Latin America, the common vampire bat Desmodus rotundus is primary reservoir of rabies, a zoonotic virus that kills thousands livestock annually and causes sporadic lethal human rabies outbreaks. The proliferation provides an abundant food resource for this obligate blood‐feeding species could alter its foraging behaviour transmission, but poor understanding dietary plasticity bats limits how influences risk. We analysed individual‐ population‐level by applying δ 13 C 15 N stable...
Abstract Fishing is widely considered a leading cause of biodiversity loss in marine environments, but the potential effect on ecosystem processes, such as nutrient fluxes, less explored. Here, we test how fishing Caribbean coral reefs influences and functions provided by fish community, that is, fish-mediated capacity. Specifically, modelled five processes storage (in biomass) supply (via excretion) nutrients, well measure their multifunctionality, onto 143 species reef fishes across 110...
Abstract Artificial reefs are used around the world for many purposes, including widespread deployment to increase fishery yields. These well‐studied from a direct fisheries‐based perspective, drawing largely on traditional theory and methodological approaches population community ecology. Here we provide an alternative perspective using basic tenets of ecosystem We focus primary production, as this process necessarily constrains secondary production fish invertebrates. use ecology viewpoint...
Seagrass beds provide tremendous services to society, including the storage of carbon, with important implications for climate change mitigation. Prioritizing conservation this valuable natural capital is global significance, and seagrass in carbon markets through projects that minimize loss, increase area or restore degraded areas represents a mechanism towards end. Using newly available Caribbean distribution data, we estimated region calculated economic valuations total ecosystem storage....
Understanding the extent to which people and wildlife overlap in space time is critical for conservation of biodiversity ecological services. Yet, how global change will reshape future human-wildlife has not been assessed. We show that potential spatial human populations 22,374 terrestrial vertebrate species increase across ~56.6% decrease only ~11.8% Earth's surface by 2070. Increases are driven primarily intensification population densities, distributions caused climate change. The strong...
Summary 1 Anthropogenic eutrophication is among the greatest threats to ecosystem functioning globally, often occurring via enrichment of both nitrogen (N) and phosphorus (P). As such, recent attention has focused on implications non‐additive responses dual nutrient inherent difficulty associated with predicting their combined effects. 2 We used a simple metric quantify frequency magnitude by N, P N + in 653 experiments conducted across multiple types locations. 3 Non‐additive were found be...
We quantified how two human impacts (overfishing and habitat fragmentation) in nearshore marine ecosystems may affect ecosystem function by altering the role of fish as nutrient vectors. empirically size-specific excretion rates one most abundant fishes (gray snapper, Lutjanus griseus) The Bahamas combined these with surveys abundance to estimate population-level rates. study was conducted across gradients disturbances: overfishing fragmentation (estuaries bisected roads), evaluate each...
Biogeochemical hotspots can be driven by aggregations of animals, via excretion, that provide a concentrated source limiting nutrients for primary producers. In subtropical seagrass ecosystem, we characterized thresholds ecological change associated with such surrounding artificial reef habitats. We deployed reefs three sizes to aggregate fishes at different densities (and thus levels nutrient supply excretion) and examined characteristics reflect ecosystem processes. Responses varied as...
Current approaches for biodiversity conservation and management focus on sustaining high levels of diversity among species to maintain ecosystem function. We show that the individuals within a single population drives function at scale. Specifically, nutrient supply from individual fish differs average >80% time, accounting this variation nearly doubles estimates nutrients supplied ecosystem. test how (i.e., selective harvest regimes) can alter find strategies targeting more active reduce up...
Abstract Energy flow and nutrient cycling dictate the functional role of organisms in ecosystems. Fishes are key vectors carbon (C), nitrogen (N) phosphorus (P) aquatic systems, quantification elemental fluxes is often achieved by coupling bioenergetics stoichiometry. While limitation has been accounted for several stoichiometric models, there no current implementation that permits its incorporation into a approach to predict ingestion rates. This may lead biased estimates fluxes. Here, we...
Abstract Animal-mediated nutrient dynamics are critical processes in ecosystems. Previous research has found animal-mediated supply (excretion) to be highly predictable based on allometric scaling, but similar efforts find universal predictive relationships for an organism’s body content have been inconclusive. We use a large dataset from diverse tropical marine community test three frameworks predicting content. show that does not follow scaling laws and it is well explained by trophic...
Abstract Improving coral reef conservation requires heightened understanding of the mechanisms by which cope with changing environmental conditions to maintain optimal health. We used a long‐term (10 month) in situ experiment two phylogenetically diverse scleractinians ( Acropora palmata and Porites porites ) test how coral–symbiotic algal interactions changed under real‐world that were priori expected be beneficial (fish‐mediated nutrients) harmful, but non‐lethal, for (fish + anthropogenic...
