Valuing Biodiversity in Life Cycle Impact Assessment
Erratum published on 13 March 2020, see Sustainability 2020, 12(6), 2270. https://doi.org/10.3390/su11205628In this article, the authors propose an impact assessment method for life cycle assessment (LCA) that adheres to established LCA principles for land use-related impact assessment, bridges current research gaps and addresses the requirements of different stakeholders for a methodological framework. The conservation of biodiversity is a priority for humanity, as expressed in the framework of the Sustainable Development Goals (SDGs). Addressing biodiversity across value chains is a key challenge for enabling sustainable production pathways. Life cycle assessment is a standardised approach to assess and compare environmental impacts of products along their value chains. The impact assessment method presented in this article allows the quantification of the impact of land-using production processes on biodiversity for several broad land use classes. It provides a calculation framework with degrees of customisation (e.g., to take into account regional conservation priorities), but also offers a default valuation of biodiversity based on naturalness. The applicability of the method is demonstrated through an example of a consumer product. The main strength of the approach is that it yields highly aggregated information on the biodiversity impacts of products, enabling biodiversity-conscious decisions about raw materials, production routes and end user products
The Cannibal and the Caterpillar: Violence, Pain, and Becoming-Man in Early Twentieth Century Germany
In the wake of Foucauldian thought, the self and its identity are often regarded as the result of disciplinary practices and technologies, inscribing the law into the body which is depicted as a passive, pliable matter. This account echoes the binary divisions between nature/culture, mind/body, and sex/gender. Feminist scholars have repeatedly questioned this Cartesian dichotomy. This essay explores the potential of DeleuzoGuattarian feminist theory to capture the affective momentum of the body as an agent in its own right: its capacity to establish affective, visceral, carnal connections and thereby to transform itself. It focusses on the case of Peter Kürten, a serial sex criminal, and his incarceration in early twentieth-century Germany. Following Elizabeth Grosz’s suggestion to imagine body and mind, matter and discourse as locked to each other in a Möbius strip, it argues that even in extreme situations of confinement and discipline, we can detect the interconnectedness of disciplinary power and bodily potentia without pre-suming one has supremacy over the other.

Species-specific foraging strategies of the syntopical and synchronous bees Panurgus calcaratus (Scopoli, 1763) and Dasypoda hirtipes (Fabricius, 1793) (Hymenoptera: Apidae).
Die Sammelstrategie der beiden endogäischen, oligolektischen syntop und synchron auftretenden Wildbienenarten Panurgus calcaratus (Scopoli, 1763) und Dasypoda hirtipes (Fabricius, 1793) wurden im Naturschutzgebiet Wahner Heide (Rheinland, BRD) untersucht. Saisonale und diurnale Rhythmik sowie die Sammelstrategien beider Arten wurden erfaßt, um eventuell bestehende Trennungsmechanismen oder Nischendiffenzierung aufzudecken. Neben dem Verproviantierungsverhalten der Bienen wurde die Oligolektie durch Pollenentnahme von Weibchen und durch Beobachtung an den Pollenquellen überprüft. Beide Arten nutzen ausschließlich gelbe, photonastische, zungenblütige Asteraceae als Pollenquellen, präferieren sandige Flächen mit geringer Vegetation als Nistplatz und sind von Anfang Juli bis Ende August aktiv. Eine Spezialisierung innerhalb der Oligolektie auf einzelne Arten zungenblütiger Asteraceae konnte nicht erkannt werden. Dasypoda hirtipes wies eine allgemein längere diurnale Aktivität auf und war zudem auch bei geringeren Temperaturen noch aktiv. Die Pollensammelaktivitäten werden bei beiden Arten maßgeblich von den photonastischen Pollenquellen limitiert. Desweiteren ist die Bienenaktivität von klimatischen Faktoren wie Lichtintensität, Bewölkung und Lufttemperatur abhängig. Artspezifische diurnale und saisonale Verhaltensweisen und Aktivitätsrhythmen werden im Hinblick auf Körpergröße und -farbe, Hitzeabsorptions- und Reflektions-Fähigkeit, Überhitzungsgefahr sowie Effekte der Ekto- und Heterothermie auf den Wärmehaushalt diskutiert. Jede Art verfolgt eine eigene Sammelstrategie, welche hauptsächlich durch ultimative Faktoren wie die Physiologie der jeweiligen Bienenart beeinflußt und zugleich limitiert wird. Weder Nistplatzangebot noch die Ressourcen Pollen oder Nektar sind im Untersuchungsgebiet begrenzt, so daß keine Evidenz für Konkurrenz zwischen den beiden Arten besteht.StichwörterInterspecific competition, oligolecty, optimal foraging strategies, photonasty, resource partitioning, separation mechanisms.Two ground-nesting, oligolectic bee species, Panurgus calcaratus (Scopoli, 1763) and Dasypoda hirtipes (Fabricius, 1793), which are syntopical and synchronous, were studied in the Wahner Heide Nature Reserve (Rhineland, Germany). To study mechanisms of ecological separation or niche differentiation the species-specific seasonal and diurnal rhythms and the foraging strategies were examined. In addition to provisioning behaviour, their oligolecty was examined by analysing pollen samples from females after flower-visiting and by observations of the bees on their pollen sources. Both species exclusively visit yellow, photonastic liguliflorous Asteraceae as pollen sources, prefer to construct their nests on sandy soils with poor vegetation and are active from the beginning of July until the end of August. Analysed samples show pollen grains belonging to yellow liguliflorous Asteraceae only and there was no specialisation within the oligolecty on certain plant species. Collection of pollen is limited by the photonastic flowers of the pollen sources, and the bee activity is mainly influenced by climatic factors like light intensity, cloudcover, and air-temperature. The diurnal activity period of Dasypoda hirtipes is much longer and this species is active at lower temperatures. The specific diurnal and seasonal behaviour and activity rhythm of the two bee species are discussed with regard to body size and coloration, the ability of heat absorption and reflection, risk of overheating, and ecto- and heterothermal effects to heat budgets. Each species follows its own foraging strategy which is mainly influenced and limited by ultimate factors as the bees` physiology under the given abiotic conditions. Neither nesting sites nor pollen and nectar resources are limited and consequently there is no evidence for competition between both species.KeywordsInterspecific competition, oligolecty, optimal foraging strategies, photonasty, resource partitioning, separation mechanisms
Association of magnesium and vitamin D status with grip strength and fatigue in older adults: a 4-week observational study of geriatric participants undergoing rehabilitation.
BACKGROUND
Low magnesium and vitamin D levels negatively affect individuals' health.
AIMS
We aimed to investigate the association of magnesium status with grip strength and fatigue scores, and evaluate whether this association differs by vitamin D status among older participants undergoing geriatric rehabilitation.
METHODS
This is a 4-week observational study of participants aged ≥ 65 years undergoing rehabilitation. The outcomes were baseline grip strength and fatigue scores, and 4-week change from baseline in grip strength and fatigue scores. The exposures were baseline magnesium tertiles and achieved magnesium tertiles at week 4. Pre-defined subgroup analyses by vitamin D status (25[OH]D < 50 nmol/l = deficient) were performed.
RESULTS
At baseline, participants (N = 253, mean age 75.7 years, 49.4% women) in the first magnesium tertile had lower mean grip strength compared to participants in the third tertile (25.99 [95% CI 24.28-27.70] vs. 30.1 [95% CI 28.26-31.69] kg). Similar results were observed among vitamin D sufficient participants (25.54 [95% CI 22.65-28.43] kg in the first magnesium tertile vs. 30.91 [27.97-33.86] kg in the third tertile). This association was not significant among vitamin D deficient participants. At week 4, no significant associations were observed between achieved magnesium tertiles and change in grip strength, overall and by vitamin D status. For fatigue, no significant associations were observed.
CONCLUSIONS
Among older participants undergoing rehabilitation, magnesium status may be relevant for grip strength, particularly among vitamin D sufficient individuals. Magnesium status was not associated with fatigue, regardless of vitamin D status.

ESPEN Guideline on Clinical Nutrition and Hydration in Geriatrics
Background: Malnutrition and dehydration are widespread in older people, and obesity is an increasing problem. In clinical practice, it is often unclear which strategies are suitable and effective in counteracting these key health threats. Aim: To provide evidence-based recommendations for clinical nutrition and hydration in older persons in order to prevent and/or treat malnutrition and dehydration. Further, to address whether weight-reducing interventions are appropriate for overweight or obese older persons. Methods: This guideline was developed according to the standard operating procedure for ESPEN guidelines and consensus papers. A systematic literature search for systematic reviews and primary studies was performed based on 33 clinical questions in PICO format. Existing evidence was graded according to the SIGN grading system. Recommendations were developed and agreed in a multistage consensus process. Results: We provide eighty-two evidence-based recommendations for nutritional care in older persons, covering four main topics: Basic questions and general principles, recommendations for older persons with malnutrition or at risk of malnutrition, recommendations for older patients with specific diseases, and recommendations to prevent, identify and treat dehydration. Overall, we recommend that all older persons shall routinely be screened for malnutrition in order to identify an existing risk early. Oral nutrition can be supported by nursing interventions, education, nutritional counselling, food modification and oral nutritional supplements. Enteral nutrition should be initiated if oral, and parenteral if enteral nutrition is insufficient or impossible and the general prognosis is altogether favorable. Dietary restrictions should generally be avoided, and weight-reducing diets shall only be considered in obese older persons with weight-related health problems and combined with physical exercise. All older persons should be considered to be at risk of low-intake dehydration and encouraged to consume adequate amounts of drinks. Generally, interventions shall be individualized, comprehensive and part of a multimodal and multidisciplinary team approach. Conclusion: A range of effective interventions is available to support adequate nutrition and hydration in older persons in order to maintain or improve nutritional status and improve clinical course and quality of life. These interventions should be implemented in clinical practice and routinely used
