The notion of people and nature as intertwined and embedded in the biosphere is gaining traction in contemporary scientific discourses. But what does it mean for a human being to be intertwined? Here, we explore this question through two lenses: looking at the human body as an open living system in continuous exchange with the chemical elements on Earth; and looking across the biosphere, at the intricate functioning of the web...
Gross ecosystem product (GEP): Quantifying nature for environmental and economic policy innovationNARA Subscribed
The large-scale loss of ecosystem assets around the world, and the resultant reduction in the provision of nature’s benefits to people, underscores the urgent need for better metrics of ecological performance as well as their integration into decision-making. Gross ecosystem product (GEP) is a measure of the aggregate monetary value of final ecosystem-related goods and services in a specific area and for a given accounting per...
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop yield, as well as to anticipate changes in this service, develop predictions, and...
Our future in the Anthropocene biosphereNARA Subscribed
The COVID-19 pandemic has exposed an interconnected and tightly coupled globalized world in rapid change. This article sets the scientific stage for understanding and responding to such change for global sustainability and resilient societies. We provide a systemic overview of the current situation where people and nature are dynamically intertwined and embedded in the biosphere, placing shocks and extreme events as part of th...
Aim Biomes, biogeographical realms and ecoregions have become central concepts of biotic organization and biodiversity research. Recent data‐intensive analysis has shown that, while ecoregions do delineate biotic communities, how distinct they are from one another varies considerably across regions and taxa. Given their central importance to global models of the earth system and to the development of conservation plans, it is...
Article impact statement : New collaborations with accounting research can improve conservation impact of ecosystem‐based information systems.
Land‐use change and climate change are driving a global biodiversity crisis. Yet, how species' responses to climate change are correlated with their responses to land‐use change is poorly understood. Here, we assess the linkages between climate and land‐use change on birds in Neotropical forest and agriculture. Across > 300 species, we show that affiliation with drier climates is associated with an ability to persist in and co...
Thermal niche predicts tolerance to habitat conversion in tropical amphibians and reptilesNARA Subscribed
Habitat conversion is a major driver of the biodiversity crisis, yet why some species undergo local extinction while others thrive under novel conditions remains unclear. We suggest that focusing on species' niches, rather than traits, may provide the predictive power needed to forecast biodiversity change. We first examine two Neotropical frog congeners with drastically different affinities to deforestation and document how t...
A protocol for eliciting nonmaterial values through a cultural ecosystem services frameNARA Subscribed
Stakeholders’ nonmaterial desires, needs, and values often critically influence the success of conservation projects. These considerations are challenging to articulate and characterize, resulting in their limited uptake in management and policy. We devised an interview protocol designed to enhance understanding of cultural ecosystem services (CES). The protocol begins with discussion of ecosystem‐related activities (e.g., rec...
The future of biodiversity and ecosystem services depends largely on the capacity of human‐dominated ecosystems to support them, yet this capacity remains largely unknown. Using the framework of countryside biogeography, and working in the Las Cruces system of Coto Brus, Costa Rica, we assessed reptile and amphibian assemblages within four habitats that typify much of the Neotropics: sun coffee plantations (12 sites), pasture...
The loss of apex predators is known to have reverberating consequences for ecosystems, but how changes in broader predator assemblages affect vital ecosystem functions and services is largely unknown. Predators and their prey form complex interaction networks, in which predators consume not only herbivores but also other predators. Resolving these interactions will be essential for predicting changes in many important ecosyste...
Efforts to maximise crop yields are fuelling agricultural intensification, exacerbating the biodiversity crisis. Low‐intensity agricultural practices, however, may not sacrifice yields if they support biodiversity‐driven ecosystem services. We quantified the value native predators provide to farmers by consuming coffee's most damaging insect pest, the coffee berry borer beetle ( Hypothenemus hampei ). Our experiments in Costa...
Intensive agriculture erodes β‐diversity at large scalesNARA Subscribed
Biodiversity is declining from unprecedented land conversions that replace diverse, low‐intensity agriculture with vast expanses under homogeneous, intensive production. Despite documented losses of species richness, consequences for β‐diversity, changes in community composition between sites, are largely unknown, especially in the tropics. Using a 10‐year data set on Costa Rican birds, we find that low‐intensity agriculture s...
Reconnecting to the BiosphereNARA Subscribed
Understanding the persistence mechanisms of tropical forest species in human‐dominated landscapes is a fundamental challenge of tropical ecology and conservation. Many species, including more than half of Costa Rica's native land birds, use mostly deforested agricultural countryside, but how they do so is poorly known. Do they commute regularly to forest or can some species survive in this human‐dominated landscape year‐round?...
Evaluating the Potential for Conservation Development: Biophysical, Economic, and Institutional PerspectivesNARA Subscribed
The widespread conversion of rural land to low‐density residential development poses an immediate threat to biodiversity and to the provision of ecosystem services. Given that development will continue and environmental stakes are high, analyzing alternative growth strategies is critical. Conservation development is one such strategy that has the potential to benefit ecosystems and diverse stakeholders including developers, ho...
