More diverse communities are thought to be more stable—the diversity–stability hypothesis—due to increased resistance to and recovery from disturbances. For example, high diversity can make the presence of resilient or fast growing species and key facilitations among species more likely. How natural, ...
The definition of conservation units is crucial for the sustainable management of endangered species, though particularly challenging when recent and past anthropogenic and natural gene flow might have played a role. The conservation of the European grayling, Thymallus thymallus, is particularly complex ...
Misgurnus anguillicaudatus has several natural ploidy types. To investigate whether nuclear polyploidy have an impact on mitochondrial DNA (mtDNA), the complete mitochondrial genomes (mitogenomes) of five distinct ploidy M. anguillicaudatus (natural diploid, triploid, tetraploid, pentaploid and hexaploid), ...
Black abalone, Haliotis cracherodii, populations along the NE Pacific ocean have declined due to the rickettsial disease withering syndrome (WS). Natural recovery on San Nicolas Island (SNI) of Southern California suggested the development of resistance in island populations. Experimental challenges ...
The European clam, Ruditapes decussatus is a species with a high commercial importance in Portugal and other Southern European countries. Its production is almost exclusively based on natural recruitment, which is subject to high annual fluctuations. Increased knowledge of the natural reproductive cycle ...
Abstract Corporate assessment of the impacts and dependencies associated with ecosystem services is coming of age. The processes has happened quietly, due in part to the 2012 update of the International Finance Corporation’s Performance Standards, and resulting expansion of due diligence for the 79 ...
Abstract A weight-of-evidence (WOE) approach was used to evaluate whether produced water (PW) discharges in the Gulf of Guinea, offshore Nigeria were having an undesirable effect on the marine ecosystem. The Nigeria study comprised an evaluation of PW constituent fate and effects in biotic (tissue) ...
Abstract The temperate waters of California support a number of offshore oil and gas structures including platforms, pipelines, piers, and other associated infrastructure. Temperate environments support some of the Earth’s most diverse and productive marine ecosystems found such as complex rocky reefs, ...
Abstract Social investments by the energy sector are often pursued separately from environmental programs, which can miss opportunities for mutually-reinforced outcomes. Since 2012, "Chevron Liberia Limited" (therafter referred as "Chevron Liberia") and Conservation International (CI) have partnered ...
Abstract SME development is well established in some of Yemen’s Governorates. However, the Shabwah Governorate in which the Company operates is constrained by financial and other resources including a lack of support for small and micro-enterprise (SME) development. The majority of the Company’s project ...
Abstract Oil and gas activities raise important socio-economic questions for host governments, local communities and project proponents alike. If not identified and managed in a timely and effective manner, socio-economic issues - such as labour market effects, population influx, revenue management, ...
Abstract Development of the oil sands in northeastern Alberta is an important contributor to the economies of both Alberta and Canada, but this type of hydrocarbon resource is often perceived by some as representing daunting environmental challenges. One particular area of stakeholder focus is the ...
Abstract The Deep-ocean Environmental Long-term Observatory System (DELOS) was installed in Block 18 Angola in February 2009, and will celebrate its 5th anniversary in February 2014. The two DELOS platforms are located in 1,400m of water, one within 50 metres of subsea facilities, and the second 16km ...
Abstract Constrained access to oil and gas reserves is one of the top risks for future oil and gas. The best energy opportunities are in frontier areas and in new unconventional resources, but these often overlap with environmentally sensitive or refuge areas.Advances in technology have brought these ...
Abstract Like any other industry, in the oil and gas business accidents always cost money and can adversely affect production cost. Blow Out events can be undoubtedly recognized as the most severe accident posed by exploration and production activities, and their hazardousness and severe consequences ...
Abstract Potential impacts from anthropogenic sound on marine life, including from geophysical operations, have received ever-increasing attention in recent years from regulators, environmental non-governmental organizations, fishing organizations and the public. As a result, many national government ...
Abstract The Chevron San Ardo Facility Unit (SAFU) is a successful example of how brackish produced water can be treated and beneficially reused for freshwater irrigation while increasing domestic oil production. The SAFU produced water reuse is the culmination of a couple of decades of research, pilot ...
Abstract Understanding the utilisation of seafloor heterogeneity by different fish species is an essential prerequisite for the implementation of effective spatial management of marine ecosystems. The North Sea has long been a vital ground for the exploitation of natural resources, supporting one of ...
Abstract Mangroves are critical ecosystems given their key role in conserving biodiversity, protecting coastlines from érosion and supporting coastal resources. They may be impacted by oil and gas activities, either directly or indirectly. Restoring them is therefore of prime importance. In the Mahakam ...
Abstract Since the nineteen seventies, TOTAL E&P INDONESIE (TEPI) operates a block in the Mahakam River delta, where it coexists with local communities that live in a traditional way and get their livelihoods from agriculture and marine activities such as shrimp farming. For ten years, the relationship ...
