Catostomid fishes are a diverse family of 76+ freshwater species that are distributed across North America in many different habitats. This group of fish is facing a variety of impacts and conservation issues that are somewhat unique relative to more economically valuable and heavily managed fish species. Here, we present a brief series of case studies to highlight the threats such as migration barriers, flow regulation, environmental contamination, habitat degradation, exploitation and impacts from introduced (non-native) species that are facing catostomids in different regions. Collectively, the case studies reveal that individual species usually are not threatened by a single, isolated factor. Instead, species...
This article explores the institutional architecture in place to govern energy in the US and its underlying principles. More specifically, it identifies the key institutions involved with energy decision-making, with an emphasis on the national level and key legislative acts of the past four decades. The second section explores six historic guiding principles connected with national energy production and use, and the third section identifies how each of these conditions is eroding. The fourth section highlights the general implications of this shift for energy governance, namely that energy decision-making is now complex, inconsistent, vertically and horizontally fragmented and politicized.
The subsurface injection of fluid (water, gas, vapour) occurs worldwide for a variety of purposes, e.g. to enhance oil production (EOR), store gas in depleted gas/oil fields, recharge overdrafted aquifer systems (ASR), and mitigate anthropogenic land subsidence. Irrespective of the injection target, some areas have experienced an observed land uplift ranging from a few millimetres to tens of centimetres over a time period of a few months to several years depending on the quantity and spatial distribution of the fluid used, pore pressure increase, geological setting (depth, thickness, and area extent), and hydro-geomechanical properties of the injected formation. The present paper reviews the fundamental geomechanical...
In this article, the Lovins'[2] explain what is meant by Natural Capitalism, four principles that enable business to behave responsibly towards both nature and people while increasing profits, inspiring their workforce and gaining competitive advantage. It combines radically increased resource productivity; closed-loop, zero-waste, nontoxic production; a business model that rewards both; and reinvestment in natural capital. The article describes how, even today, when nature and people are typically valued at zero, protecting and restoring nature, culture and community can be far more profitable than liquidating them.

Our demands on natural systems outweigh the capacity of those systems to support us. This paper calls for an approach to development that consistently delivers ‘net benefit’ for biodiversity or ‘ecological enhancement’. Examples of enhancement are presented through four case studies in India undertaken between 2005 and 2010. Actions focus on improving the overall ecological structure, composition and functions of sites; strengthening ecological networks by creating new habitats and buffer areas; and improving the services provided by the ecosystems, without jeopardizing biodiversity. While recognizing the importance of quantitative metrics of impacts and mitigation measures to determine outcomes, such measures were...
