Abstract:
... Ecological risk assessments play an important role in environmental management and decision-making. Although empirical measurements of the effects of habitat changes and chemical exposure are often made at molecular and individual levels, environmental decision-making often requires the quantification of management-relevant, population-level outcomes. In this study, we generalized a modeling frame ...

Abstract:
... Resilience planning requires an understanding of the potential impact of accelerated sea level rise on the narrow coastal habitats between the sea and the built environment in urban estuaries. Preliminary work suggests that facilitating expansion of coastal upland vegetation (grasslands and maritime shrubland/successional maritime forest) may improve resilience. We created a GIS model for Jamaica ...

Abstract:
... Enhancing consideration of the ecosystem services concept within decision-making calls for integration of local knowledge and data within assessments to capture context-specific spatial and thematic detail. This paper demonstrates how local knowledge and (biophysical, sociocultural, economic) data can be integrated within ecosystem service assessments by use of well-established spatial quantificat ...

Abstract:
... The growth of yellowfin tuna has been the subject of considerable research efforts since the early 1960s. Most studies support a complex two-stanza growth pattern with a sharp acceleration departing from the von Bertalanffy growth curve used for most fish populations. This growth pattern has been assumed to result from a combination of physiological, ecological and behavioral factors but the role ...

Abstract:
... Agricultural land expansion and intensification, driven by human consumption of agricultural goods, are among the major threats to environmental degradation and biodiversity conservation. Land degradation can ultimately hamper agricultural production through a decrease in ecosystem services. Thus, designing viable land use policies is a key sustainability challenge. We develop a model describing t ...

The study of production–living–ecological space (PLES) is essential for the sustainable use of land resources and regional socioeconomic development, and several studies have adopted PLES-based evaluation indices. However, few studies have investigated the effects of governmental regulation and human activity on the optimal allocation of land for different uses. Crucially, the non-optimal use of l ...

Abstract:
... Existing studies disjointly addressed the environmental convergence and environmental Kuznets curve hypotheses, though these research lines are theoretically interconnected. This paper proposes a unified empirical methodology to simultaneously investigate both hypotheses, relying on a semiparametric dynamic panel data model that accounts for regressor endogeneity. The approach, when applied to CO₂ ...

Abstract:
... Correct modelling of relationships between predators and prey is crucial to ecological and population dynamics models. However, and despite a long-standing competition between ratio and prey-dependent models (and a few alternative intermediate forms) in the literature, most equations currently used to represent such relationships do not meet theoretical criteria for biological consistency. This re ...

Abstract:
... Integrated Multi-Trophic Aquaculture (IMTA) systems have been designed to optimize nutrient and energy use, to decrease waste, and to diversify fish-farm production. Recently, the development of detritivorous aquaculture has been encouraged, as detrivores can consume organic particulate matter, reducing benthic eutrophication and the environmental footprint of aquaculture. To this end, the polycha ...

Abstract:

Abstract:
... Modeling energy content and gain of individuals is of increasing importance in ecosystem modeling, especially in aquaculture and fisheries. Traditional models for estimating the content and gain are either imprecise or expensive, in part because of intensive data requirements. Here we show how routine biometric data (length and wet weight or condition index) can be used to estimate total energy co ...

Abstract:
... Direct and indirect biological interactions and trophic cascades suppressing a trophic level in the food web can control entire marine ecosystems.
