Colour vision in thrips (Thysanoptera)

Insects are an astonishingly successful and diverse group, occupying the gamut of habitats and lifestyle niches. They represent the vast majority of described species and total terrestrial animal biomass on the planet. Their success is in part owed to their sophisticated visual systems, including colour vision, which drive a variety of complex behaviours. However, the majority of research on insec

Colour vision in nocturnal insects

The ability to see colour at night is known only from a handful of animals. First discovered in the elephant hawk moth Deilephila elpenor, nocturnal colour vision is now known from two other species of hawk moths, a single species of carpenter bee, a nocturnal gecko and two species of anurans. The reason for this rarity - particularly in vertebrates - is the immense challenge of achieving a suffic

The Effects of Transnational Municipal Networks on Urban Climate Politics in the Global South

Transnational municipal networks (TMNs) have emerged as important actors in the global response to climate change. Environmentalists both within and outside governments have placed great expectations and hopes on these networks. Through their novel form of agency, TMNs are expected to provide cities with a form of ‘extra-legem’ empowerment in their responses to climate change. This empowerment is

Global Political Economy and Development

This chapter introduces four different approaches that have tackled this issue: Environmental Economics, International Political Economy and Development Studies, Global Environmental Governance and Earth System Governance, as well as Political Ecology. It also introduces these perspectives and highlights their maincontributions to the literature in their historical context. The chapter discusses d

Mechanisms of spectral orientation in a diurnal dung beetle

Ball rolling dung beetles use a wide range of cues to steer themselves along a fixed bearing, including the spectral gradient of scattered skylight that spans the sky. Here, we define the spectral sensitivity of the diurnal dung beetle Kheper lamarcki and use the information to explore the orientation performance under a range of spectral light combinations. We find that, when presented with spect

Conclusion : Towards a ‘Deep Debate’ on the Anthropocene

In this edited volume, we explored the contributions that political science as a discipline can offer to the evolving Anthropocene debate. The term Anthropocene denotes a new geological epoch in the Earth’s history in which humans have become the main drivers of planetary-wide changes. Some authors interpret this as good news, pointing to progress as a result of human ingenuity and the endless pos

Colour vision in ants (Formicidae, Hymenoptera)

Ants are ecologically one of the most important groups of insects and exhibit impressive capabilities for visual learning and orientation. Studies on numerous ant species demonstrate that ants can learn to discriminate between different colours irrespective of light intensity and modify their behaviour accordingly. However, the findings across species are variable and inconsistent, suggesting that

The anthropocene debate and political science

Anthropocene has become an environmental buzzword. It denotes a new geological epoch that is human-dominated. As mounting scientific evidence reveals, humankind has fundamentally altered atmospheric, geological, hydrological, biospheric, and other Earth system processes to an extent that the risk of an irreversible system change emerges. Human societies must therefore change direction and navigate

Introduction : A Political Science Perspective on the Anthropocene

Over the past decades, it has become more and more obvious that ongoing globalisation processes have substantial impacts on the natural environment. Studies reveal that intensified global economic relations have caused or accelerated dramatic changes in the Earth system, defined as the sum of our planet’s interacting physical, chemical, biological and human processes (Schellnhuber et al. 2004). Cl

Molecular advances to study the function, evolution and spectral tuning of arthropod visual opsins

Visual opsins of vertebrates and invertebrates diversified independently and converged to detect ultraviolet to long wavelengths (LW) of green or red light. In both groups, colour vision largely derives from opsin number, expression patterns and changes in amino acids interacting with the chromophore. Functional insights regarding invertebrate opsin evolution have lagged behind those for vertebrat

Colour vision in stomatopod crustaceans

The stomatopod crustaceans, or mantis shrimps, are colourful marine invertebrate predators. Their unusual compound eyes have dorsal and ventral regions resembling typical crustacean apposition designs separated by a unique region called the midband that consists of from two to six parallel rows of ommatidia. In species with six-row midbands, the dorsal four rows are themselves uniquely specialized

Extremal states and coupling properties in electroelasticity

Electroelastic materials possess properties most attractive for the design of smart devices and systems such as actuators and sensors. Typical polymers show changes in shape under the action of an electric field, and vice versa, together with fast actuation times, high strain levels and low elastic moduli. This paper deals with an Ogden model inspired framework for large deformation electroelastic

The Political Impact of the Sustainable Development Goals : Transforming Governance through Global Goals?

Written by an international team of over sixty experts and drawing on over three thousand scientific studies, this is the first comprehensive global assessment of the political impact of the Sustainable Development Goals, which were launched by the United Nations in 2015. It explores in detail the political steering effects of the Sustainable Development Goals on the UN system and the policies of

Dependencies of Four Mechanisms of Secondary Ice Production on Cloud-Top Temperature in a Continental Convective Storm

Various mechanisms of secondary ice production (SIP) cause multiplication of numbers of ice particle, after the onset of primary ice. A measure of SIP is the ice enhancement ratio (“IE ratio”) defined here as the ratio between number concentrations of total ice (excluding homogeneously nucleated ice) and active ice-nucleating particles (INPs). A convective line observed on 11 May 2011 over the Sou

The performance of plasma amyloid beta measurements in identifying amyloid plaques in Alzheimer's disease : a literature review

The extracellular buildup of amyloid beta (Aβ) plaques in the brain is a hallmark of Alzheimer's disease (AD). Detection of Aβ pathology is essential for AD diagnosis and for identifying and recruiting research participants for clinical trials evaluating disease-modifying therapies. Currently, AD diagnoses are usually made by clinical assessments, although detection of AD pathology with positron e

Cholesterol metabolism in breast cancer: Prognostic factors and optimizing treatment

AbstractBreast cancer (BC) is the most common cancer among women in Sweden and worldwide. Adjuvant endocrine therapies are effective, yet 20-30% patients experience disease relapse. Altered cholesterol metabolism is an emerging hallmark of breast cancer proliferation and endocrine therapy resistance. Studies have shown that the use of cholesterol-lowering medications (statins) reduces the risk of

Site-dependent nuclear dynamics in core-excited butadiene

Symmetry breaking and competition between electronic decay and nuclear dynamics are major factors determining whether the memory of the initial core-hole localisation in a molecule is retained long enough to affect fragmentation. We investigate the fate of core holes localised at different sites in the free 1,3 trans butadiene molecule by using synchrotron radiation to selectively excite core

Skogen är bäst på bild

Skogen är bäst på bild is an electroacoustic text-sound-composition work; it could also be considered a radiophonic work. This was the first work of text-sound composition I ever made, repurposing that more abstract genre here as a direct tool for finding memory and identity in the city. Although Stockholm’s history of text-ljud-komposition (text-sound-composition) is something I have engaged with
