Summary Climate change has been inducing range shifts for many species as they follow their suitable climate space and further are projected. Whether will be able to colonize regions where conditions become suitable, so‐called ‘new space’, depends on traits habitat fragmentation. By combining bioclimate envelope models with dispersal models, we identified areas the spatial cohesion of ecosystem pattern is expected insufficient allow colonization new space. For each three types, were selected...
Abstract Techniques for assessing the impact of structural barriers on fish passage and prioritising restoration actions are reviewed. Current survey methodologies biased towards specific structures, primarily culverts economically significant fish. Assessment criteria often based swimming capabilities upstream migrating adult salmonids, while ignoring other life‐stages, non‐salmonid species, downstream migration behaviour. The development comprehensive centrally owned geospatial inventories...
In many large ecosystems, conservation projects are selected by a diverse set of actors operating independently at spatial scales ranging from local to international. Although small-scale decision making can leverage expert knowledge, it also may be an inefficient means achieving large-scale objectives if piecemeal efforts poorly coordinated. Here, we assess the value coordinating in both space and time maximize restoration aquatic ecosystem connectivity. Habitat fragmentation is leading...
European rivers are disconnected by more than one million man-made barriers that physically limit aquatic species migration and contribute to modification of freshwater habitats. Here, a Conceptual Habitat Alteration Model for Ponding is developed aid in evaluating the effects impoundments on fish Fish communities present with low human impact their broad environmental settings enable classification into 15 macrohabitat types. These classifications, together estimated sensitivity alteration...
Abstract Spatial prioritization tools provide a means of finding efficient trade‐offs between biodiversity protection and the delivery ecosystem services. Although large number approaches have been proposed in literature, most are specifically designed for terrestrial systems. When applied to river ecosystems, they often fail adequately account essential role that landscape connectivity plays maintaining both This is particularly true longitudinal connectivity, which many catchments highly...
Abstract Road crossings can act as barriers to the movement of stream fishes, resulting in habitat fragmentation, reduced population resilience environmental disturbance and higher risks extinction. Strategic barrier removal has potential improve connectivity networks, but managers lack a consistent framework for determining which projects will most benefit target species. The objective this study is develop method identifying prioritizing action on road order restore network connectivity....
Summary The presence of dams, stream–road crossings and other infrastructure often compromises the connectivity rivers, leading to reduced fish abundance diversity. assessment mitigation river barriers is critical success restoration efforts aimed at restoring integrity. In this study, we present a combined modelling approach involving statistical regression methods mixed integer linear programming maximize resident species richness within catchment through targeted barrier mitigation....
Structures that block movement of fish through river networks are built to serve a variety societal needs, including transportation, hydroelectric power, and exclusion exotic species. Due their abundance, road crossings dams reduce the amount habitat available migrate from sea or lakes into rivers breed. The benefits removing any particular barrier depends on its location within network, passability fish, relative position other barriers network. Balancing trade‐offs between ecological...
Abstract Agricultural expansion is the primary driver of ecological degradation across tropics. Set-asides—uncultivated parts agricultural landscapes, often on steep slopes and alongside rivers—may alleviate environmental impacts but can reduce area cultivated. Here we model an approach to configuring set-asides aimed at optimizing outcomes (biodiversity, above-ground carbon storage nutrient cycling) without reducing net cultivation area. We compare in oil palm landscape where all...
Abstract Infrastructure, such as dams, weirs and culverts, disrupt the longitudinal connectivity of rivers, causing adverse impacts on fish other aquatic species. Improving passage at artificial barriers, accordingly, can be an especially effective economical river restoration option. In this article, we propose a novel, mixed integer programing model for optimizing barrier mitigation decisions given limited budget. Rather than simply treating barriers being impassable or not, consider more...
Controlling invasive species is critical for conservation but can have unintended consequences native and divert resources away from other efforts. This dilemma occurs on a grand scale in the North American Great Lakes, where dams culverts block tributary access to habitat of desirable fish are lynchpin long-standing efforts limit ecological damage inflicted by invasive, parasitic sea lamprey (Petromyzon marinus). Habitat restoration sea-lamprey control create conflicting goals managing...
In this paper, we investigate unreliability in hub location planning. A mixed integer nonlinear programming model is formulated for optimally locating p uncapacitated hubs, each of which can fail with a site-specific probability. The objective to determine the hubs and assignment demand nodes minimize expected weighted travel cost plus penalty if all fail. linear version developed using specialized flow network called probability lattice evaluate compound terms. tabu search algorithm...
We use machine learning algorithms to investigate various aspects of residential electricity consumption for households in the Republic Ireland. Temperature, day week, and month year have an apparent causal effect on consumption. The prevalence six distinct intra-day load profiles, identified by clustering, changes dramatically between weekdays weekends as well seasonally. Key socio-demographic dwelling characteristics associated with annual profiles include household makeup size occupation...
In recent years, the extent of formal research evaluation, at all levels from individual to multiversity has increased dramatically. At institutional level, there are world university rankings based on an ad hoc combination different indicators. There also national exercises, such as those in UK and Australia that evaluate outputs environment through peer review panels. These extremely costly time consuming. This paper evaluates possibility using Google Scholar (GS) level data a relatively...
