Hemispheric asymmetries in biodiversity: a serious matter for ecology [PDF]

, 2004
[FIRST PARAGRAPH] Penguins have been receiving a lot of bad press lately. They are considered somehow counter, spare, strange. Unlike most plant and animal groups, they do not show a peak of species richness towards the equator and a decline towards the ...

Consumer Valuation of Meat Alternatives and Labeling Policies: A Comparative Perspective

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study investigates and compares US consumer perceptions and the impact of environmental, human health, and animal welfare information related to conventional meat on preferences for meat alternatives and labeling policies. Using the best–worst scaling method across 10 different burger alternatives, our results show that the meat burger is

Persistent conflict in palaeognath phylogeny revealed by quartet-based and ML analyses

Frontiers in Zoology
Background The evolutionary relationships among palaeognath birds remain contentious despite extensive phylogenomic analyses. While the ostrich is consistently identified as the earliest diverging lineage, the relationships among non-ostrich palaeognaths

Biodiversity Quality: a paradigm for biodiversity [PDF]

, 2009
The internationally accepted definition of biodiversity creates difficulty in measuring difference and change. The authors suggest that well-sampled data can be used to generate a range of numerical indices reflecting species group characteristics ...

Developing a Global Soil Regime [PDF]

, 2015
From the 1960s onwards, the global community became more aware of the phenomena of air and water pollution. More recently, the issues of climate change, loss of biodiversity, desertification, drought, and land degradation have become more prominent ...

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

The coevolutionary consequences of biodiversity change

Trends in Ecology & Evolution
Coevolutionary selection is a powerful process shaping species interactions and biodiversity. Anthropogenic global environmental change is reshaping planetary biodiversity, including by altering the structure and intensity of interspecific interactions. However, remarkably little is understood of how coevolutionary selection is changing in the process.

Sundarban mangroves: diversity, ecosystem services and climate change impacts [PDF]

, 2016
The Bengal delta coast harboring the famous Sundarban mangroves is extremely vulnerable to climate change. Already, salinity intrusion, increasing cyclones and anomalies in rainfall, and temperature, are causing many social and livelihood problems ...

Coping With Production Risk: Effects of Sown Plant Diversity on the Attractiveness of Crop Insurance in Grasslands

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Increased frequency of extreme weather events, particularly droughts, threatens grassland farming by destabilizing yields and farms' economic viability. We examine, theoretically and through numerical simulations, how sown plant diversity (natural insurance) influences the attractiveness of indemnity and drought index insurance (formal ...
