Trophic state (TS) characterizes a waterbody’s biological productivity and depends on its morphometry, physics, chemistry, biology, climate, and history. However, multiple TS operational definitions have emerged to meet use-specific classification needs. These differing operational definitions can create inconsistent understanding, can lead to miscommunication, and can result in siloed [...]

1. Global Plate Models (GPMs) aim to reconstruct the tectonic evolution of the Earth by modelling the motion of the plates and continents through time. These models enable palaeobiologists to study the past distribution of extinct organisms. However, different GPMs exist that vary in their partitioning of the Earth’s surface and the modelling of continental motions. Consequently, the preferred [...]

Crowded and warmer: unequal dengue risk at high spatial resolution across a megacity of India

The role of climate factors on transmission of mosquito-borne infections within urban landscapes must be considered in the context of the pronounced spatial heterogeneity of such environments. Socio-demographic and environmental variation challenge control efforts for emergent arboviruses, a major class of pathogens responsible for dengue, Zika and chikungunya, transmitted via the urban mosquito [...]

Lidar-based MaxEnt models to support conservation planning for endangered Red-cockaded Woodpeckers in urbanizing environments

Sensitive and intensively managed species require carefully thought-out management plans to promote and maintain specific habitat conditions. Urban features and land-use change must be assimilated into these habitat management plans, as they become increasingly present globally. As a case study, several MaxEnt species distribution models were developed that could enable habitat management efforts [...]

A successful approach to mangrove ecosystem restoration in the Mauritanian side of the Senegal River Delta

Subjects: Ecology and Evolutionary Biology

A mangrove ecosystem restoration project was carried for 3 years in the Mauritanian side of the River Senegal Delta where scarce scientific and/or technical references exist on these mangroves located in the northernmost limit on the West African coast. The construction of the Manantali and the Diama dams transformed the once exhuberant delta to an artificial estuary and had dramatically affected [...]

Calling for a National Model Benchmarking Facility

The modern world uses predictive computer models for many important purposes, including weather predictions, epidemic management, flood forecasting and warnings, and economic policymaking. We need to know how much we can trust the projections of these models, not only to achieve more accurate projections for systems, but also to undertake scientific learning about systems by incrementally testing [...]

The rise in atmospheric carbon dioxide is chiefly tied to land stewardship. Farmers and loggers have removed the plants that, until the industrial era, kept the soil fungi alive, kept soil emissions nearby by breaking the wind, and soaked those up. The result is plumes of carbon dioxide. Putting plants back in would curb these emissions. Farmers and loggers could address biodiversity loss [...]

Co-production of just nature-based solutions to mitigate the impact of domestic effluents on stream water quality in an informal urbanization in Latin America: Diagnosis and a pilot study

Subjects: Ecology and Evolutionary Biology

Nature-based solutions (NbS) are increasingly assessed in sustainable urban projects to improve human welfare and biodiversity. Particularly, the design, implementation and assessment of NbS are in most cases spatial and context-dependent, and just NbS must also be included in the agenda. To this end, alternative paradigms such as transdisciplinary and action research can play a fundamental role [...]

Towards robust interdisciplinary modeling of global human-environmental dynamics

Real-world environmental problems are typically vast, urgent, and complex. Confronted with such problems, we are often tempted to act fast by pulling together little bits and pieces from different fields and simply adding these to pre-existing models and frameworks. Seldom, though, do we pause long enough to look whether and for how long those larger structures we build can support reliable [...]

Geosphere and Biosphere coevolution: the role of trace metals availability in the evolution of biogeochemistry

Earth’s geosphere and biosphere have coevolved over time, influencing each other’s stability and keeping our planet habitable for most of its 4.543 billion years of history. Biogeochemical cycles play a key role in controlling this interaction, connecting long-term geological cycles and the much faster evolution of the Earth’s outer biologically dominated envelopes. A small set of [...]

Disentangling the effects of climate change and reoligotrophication on primary production in a large lake

Climate change and reduction in nutrient loads have significant effects on primary production and phytoplankton growth dynamics. Since in the last few decades in many regions, nutrients in lakes were reduced simultaneously as the climate changed. Yet, it remains unclear which of the two has impacted primary production the most. In this study, we couple the General Ocean Turbulence Model with the [...]

Climate change and development of data-oriented methods are appealing for new climate classification schemes. Based on the most widely used Köppen-Geiger scheme, this article proposes a neural network based climate classification method from a data science perspective. In conventional schemes, empirically handcrafted rules are used to divide climate data into climate types, resulting in certain [...]

Barren ground depressions, natural H2 and orogenic gold deposits: spatial link and geochemical model

A review of the localities in continental rocks where H2-rich gases have been reported, showed that they are mainly located near gold deposits. Two types of geomorphological features known as markers of gas venting in sedimentary basins were also systematically observed near orogenic gold deposits on satellite images. They consist in both barren ground depressions and high densities of small (< [...]

Microcystin as a Biogeochemical Cycle: pools, fluxes, and fates of the cyanotoxin in aquatic ecosystems

Microcystin poses a serious threat to aquatic ecosystems and human health. There is a pressing need to understand the production, movement, and storage of microcystin in lakes. We constructed a conceptual biogeochemical model for microcystin through a comprehensive literature synthesis, identifying four major pools and nine major fluxes in lakes that also connect to the terrestrial environment. [...]

Experimental evaluation of the effects of bigmouth buffalo (Ictiobus cyprinellus) density on shallow lake ecosystems

Bigmouth buffalo (Ictiobus cyprinellus) is a large-bodied planktivore inhabiting shallow waterways in North America and subjected to unregulated harvest throughout much of their native range. Despite high harvest pressure on some populations, we know little about the ecosystem-level effects of lowering bigmouth buffalo densities. To evaluate the effect of bigmouth buffalo density on lower trophic [...]
