Relationship between moth (night active Lepidoptera) diversity and vegetation characteristics in southern Sweden
The diversity and community composition of moths (both macro- and micromoths) at 32 sites, representing a wide range of habitat types (forests, grasslands, wetlands, agricultural and urban areas) within a restricted region in central Scania,southern-most Sweden, was investigated by use of light moth traps and compared with vascular plant species richness and habitat characteristics. The results re
Reclaiming constructive alignment
Constructive Alignment (CA) is neither the panacea, nor the unalloyed evil depicted in the majority of higher education discourses. But rather, the theory is a heuristic and accessible representation of commonly agreed upon aspects of modern curriculum and educational theory, designed explicitly to support learning and teaching. However, when imposed top-down for accountability purposes, or used a
Effects of dietary fibers on the tuft cell population in the mouse colon post radiation
Pelvic radiation therapy is often associated with gastrointestinal dysfunction. Intestinal tuft cell located within the mucosal epithelium have in the small intestine following full body radiation in mice been shown to be essential for epithelial regeneration. Dietary approaches during and after radiation therapy have also been suggested to aid epithelial health and function. Tuft cells are sugges

Effective Waves for Random Three-dimensional Particulate Materials
How do you take a reliable measurement of a material whose microstructure is random? When using wave scattering, the answer is often to take an ensemble average (average over time or space). By ensemble averaging we can the calculate the average scattered wave and the effective wavenumber. To date, the literature has focused on calculating the effective wavenumber for a plate filled with particlesHow do you take a reliable measurement of a material whose microstructure is random?

Autoimmune congenital heart block and primary Sjögren's syndrome : characterisation and outcomes of 49 cases
OBJECTIVES: To characterise autoimmune congenital heart block (CHB) associated with a maternal diagnosis of primary Sjögren's syndrome (pSS) confirmed either before, concomitant or after the first pregnancy complicated with CHB.METHODS: The following inclusion criteria were applied: (i) Mothers with positive Ro/La autoantibodies detected previously or at the time of diagnosis of the first case of
Higher risk of major adverse cardiac events after acute myocardial infarction in patients with schizophrenia
BACKGROUND: Patients with schizophrenia are a high-risk population due to higher prevalences of cardiovascular risk factors and comorbidities that contribute to shorter life expectancy.PURPOSE: To investigate patients with and without schizophrenia experiencing an acute myocardial infarction (AMI) in relation to guideline recommended in-hospital management, discharge medications and 5-year major a
Impacts of climate oscillation on precipitation and river flows of small scale river basins in Eastern Northeast Brazil
The Northeast region of Brazil is one of the most susceptible parts of the country to the effects of climate variability leading to severe droughts or extreme floods. Indeed, drought is a major issue due to a large semiarid area that covers 53% of the region, which determines the main climate characteristics of this region. On the other hand, extreme floods have caused widespread damage in river b
Byzantine Tree Life : Christianity and the Arboreal Imagination
This book examines the many ways Byzantines lived with their trees. It takes seriously theological and hagiographic tree engagement as expressions of that culture’s deep involvement—and even fascination—with the arboreal. These pages tap into the current attention paid to plants in a wide range of scholarship, an attention that involves the philosophy of plant life as well as scientific discoverie
A molecular map of murine lymph node blood vascular endothelium at single cell resolution
Blood vascular endothelial cells (BECs) control the immune response by regulating blood flow and immune cell recruitment in lymphoid tissues. However, the diversity of BEC and their origins during immune angiogenesis remain unclear. Here we profile transcriptomes of BEC from peripheral lymph nodes and map phenotypes to the vasculature. We identify multiple subsets, including a medullary venous pop
Exceptional diversity of opsin expression patterns in Neogonodactylus oerstedii (Stomatopoda) retinas
Stomatopod crustaceans possess some of the most complex animal visual systems, including at least 16 spectrally distinct types of photoreceptive units (e.g., assemblages of photoreceptor cells). Here we fully characterize the set of opsin genes expressed in retinal tissues and determine expression patterns of each in the stomatopod Neogonodactylus oerstedii Using a combination of transcriptome and
Differences in signal contrast and camouflage among different colour variations of a stomatopod crustacean, Neogonodactylus oerstedii
Animal colouration is often a trade-off between background matching for camouflage from predators, and conspicuousness for communication with con- or heterospecifics. Stomatopods are marine crustaceans known to use colour signals during courtship and contests, while their overall body colouration may provide camouflage. However, we have little understanding of how stomatopods perceive these signal
Photoresponses in the radiolar eyes of the fan worm Acromegalomma vesiculosum
Fan worms (Annelida: Sabellidae) possess compound eyes and other photoreceptors on their radiolar feeding tentacles. These eyes putatively serve as an alarm system that alerts the worm to encroaching threats, eliciting a rapid defensive retraction into their protective tube. The structure and independent evolutionary derivation of these radiolar eyes make them a fascinating target for exploring th
Behavioural evidence for polychromatic ultraviolet sensitivity in mantis shrimp
Stomatopod crustaceans are renowned for their elaborate visual systems. Their eyes contain a plethora of photoreceptors specialized for chromatic and polarization detection, including several that are sensitive to varying wavelength ranges and angles of polarization within the ultraviolet (UV) range (less than 400 nm). Behavioural experiments have previously suggested that UV photoreception plays
Developmental studies provide new insights into the evolution of sense organs in Sabellariidae (Annelida)
BACKGROUND: Sabellarids, also known as honeycomb or sandcastle worms, when building their tubes, produce chemical signals (free fatty acids) that are responsible for larval settlement and the formation of three-dimensional aggregations. The larval palps and the dorsal hump (becoming the median organ in adults) are presumed to participate in such a substrate selection during settlement. Notably, th
Sequence, Structure, and Expression of Opsins in the Monochromatic Stomatopod Squilla empusa
Most stomatopod crustaceans have complex retinas in their compound eyes, with up to 16 spectral types of photoreceptors, but members of the superfamily Squilloidea have much simpler retinas, thought to contain a single photoreceptor spectral class. In the Atlantic stomatopod Squilla empusa, microspectrophotometry shows that all photoreceptors absorb light maximally at 517 nm, indicating that a sin
Crustacean Larvae-Vision in the Plankton
We review the visual systems of crustacean larvae, concentrating on the compound eyes of decapod and stomatopod larvae as well as the functional and behavioral aspects of their vision. Larval compound eyes of these macrurans are all built on fundamentally the same optical plan, the transparent apposition eye, which is eminently suitable for modification into the abundantly diverse optical systems
