Hydropower development in the Andean Amazon has been underestimated and will disrupt connected human natural systems.
Proposed hydropower dams at more than 350 sites throughout the Amazon require strategic evaluation of trade-offs between numerous ecosystem services provided by Earth's largest and most biodiverse river basin. These are spatially variable, hence collective impacts newly built depend strongly on their configuration. We use multiobjective optimization to identify portfolios that simultaneously minimize flow, connectivity, sediment transport, fish diversity, greenhouse gas emissions while...
Salinity tolerance is one of several important physiological attributes that determine invasion success and the pattern dispersal introduced aquatic organisms. Introduced freshwater fishes able to tolerate elevated salinities have potential invade exploit brackish-water (mixohaline) environments use estuaries coastal waters as 'bridges' for dispersing from river system another. Several members neotropical suckermouth armoured catfish genus Pterygoplichthys (Siluriformes: Loricariidae)...
Although biodiversity loss adversely influences a variety of ecosystem functions, how declining wild food diversity affects nutrient supplies for people is poorly understood. Here, we analyze the impact on nutrients supplied by fish using detailed information from Peruvian Amazon, where inland fisheries provide critical source nutrition many region's 800,000 people. We found that impacts depended compensation, trophic dynamics, and functional diversity. When small sedentary species...
The Amazon River Basin's extraordinary social-ecological system is sustained by various water phases, fluxes, and stores that are interconnected across the tropical Andes mountains, lowlands, Atlantic Ocean. This "Andes-Amazon-Atlantic" (AAA) pathway a complex hydroclimatic linked regional cycle through atmospheric circulation continental hydrology. Here, we aim to articulate AAA hydroclimate as foundational for research, management, conservation, governance of aquatic systems Basin. We...
Inland fisheries feed greater than 150 million people globally, yet their status is rarely assessed due to socio-ecological complexity and pervasive lack of data. Here, we leverage an unprecedented landings time series from the Amazon, Earth's largest river basin, together with theoretical food web models examine (i) taxonomic trait-based signatures exploitation in inland fish (ii) implications changing biodiversity for resilience. In both theory, find that multi-species diverse results a...
Abstract In the Amazon, world's largest river basin, migrations within freshwater habitats are one of predominant life history strategies for fishes. The flood pulse and extensive network provide aquatic organisms with temporal spatial accessibility to a mosaic habitats. Although migratory fish species central ecosystems fisheries, knowledge patterns has traditionally relied on anecdotal scattered information, lacking unifying methodological conceptual framework. We quantitatively synthesize...
Abstract Ecosystems vary widely in their responses to biodiversity change, with some losing function dramatically while others are highly resilient. However, generalizations about how species‐ and community‐level properties determine these divergent ecosystem have been elusive because potential sources of variation (e.g., trophic structure, compensation, functional trait diversity) rarely evaluated conjunction. Ecosystem vulnerability, or the likely change following is influenced by two...
The global biodiversity that underpins wild food systems—including fisheries—is rapidly declining. Yet, we often have only a limited understanding of how households use and benefit from in the ecosystems surrounding them. Explicating these relationships is critical to forestall mitigate effects declines on nutrition security. Here, quantify filters household harvest, consumption, sale, ecological traits characteristics shape relationships. We used unique, integrated (40 sites, quarterly data...
ABSTRACT Finding pathways to more sustainable agriculture and resource use remains the most pressing challenge for Amazonian countries. Characterizing recent changes in structure types of agrarian production systems, this review identifies responses deal with challenges opportunities promote extraction economies Amazon. While regional rest on a rich diversity producers, knowledge, expansion agribusiness enterprises has come dominate distribution subsidies, institutional support, logistical...
Species, through their traits, influence how ecosystems simultaneously sustain multiple functions. However, it is unclear trait diversity sustains the contributions biodiversity makes to people. Freshwater fisheries nourish hundreds of millions people globally, but overharvesting and river fragmentation are increasingly affecting catches. We analyse loss nutritional in consumed fish portfolios affects simultaneous provisioning six essential dietary nutrients using household data from Amazon...
Abstract Wild fisheries provide billions of people with a key source multiple essential nutrients. As plateau or decline, nourishing more will partially rely on shifting consumption to farmed animals. The environmental implications transitions among animal-sourced foods have been scrutinized, but their nutritional substitutability remains unclear. We compared concentrations six dietary nutrients across >5000 species wild fishes, aquaculture, poultry and livestock species, representing...
Abstract Despite the importance of freshwater ecosystems to social‐ecological systems Amazon, conservation in region historically has focused on terrestrial ecosystems. Moreover, current information pressing management and needs specific freshwaters is scattered across multiple disciplines generally particular threats, habitats, taxa. This disparateness limits ability researchers practitioners set priorities implement actions that comprehensively address challenges faced by To reduce this...
Changes in biodiversity can severely affect ecosystem functioning, but the impacts of species loss on an ecosystem's ability to sustain multiple functions remain unclear. When considering individual functions, depend correlations between functional contributions and their extinction probabilities. functions. However, how probabilities determine impact multifunctionality (MF) is not well understood. Here, we use simulations examine influence among diversity-MF relationship. In contrast with...
Abstract Plant diversity has a positive influence on the number of ecosystem functions maintained simultaneously by community, or multifunctionality. While presence multiple trophic levels beyond plants, complexity, affects individual functions, effect complexity diversity–multifunctionality relationship is less well known. To address this issue, we tested whether independent simultaneous manipulation both plant and impacted multifunctionality using mesocosm experiment from Cedar Creek,...
