Derivation of robust predictor variables for modelling urban shrinkage and its effects at different scales
No full textCurrently, we observe diverging processes of growth and shrinkage in European Cities. Whereas in the 80ies and 90ies partially accelerated through the crash of the socialist system mostly urban growth and suburban development occurred in European Cities, today we find a general decline of population as well as an increase of aged people (as results of the demographic change in Europe and worldwide, Cloet 2003, Lutz 2001). These processes influence land use pattern (state of the environment) and land use changes in urban areas enormously. Land use pattern reflect the current socio-economic development of an urban area and give an idea of how the urban ecosystem is influenced by man. In doing so, for instance, surface sealing reduces the filtering and remediation capacity of soils and the water retention in general as well as minimises habitat quality for wetland species. At the same time, the ecosystem(s) provide so-called ecosystem services, benefits people obtain from ecosystems: water availability, drinking water, remediation and filtering of waste, places to settle, recreation facilities in nature and others. Their quantification enables to bring the change (availability/loss) of ecosystem services into relation with effective costs (economic sphere, Farber 2002, De Groot et al. 2002). The above mentioned population decline and related shrinkage processes will have enormous consequences on the demand and availability of ecosystem services needed to sustain a high and even increasing status of quality of life for European citizens in the next future. Therefore, the predictor variables describing on the one hand shrinkage-related land use changes and on the other its effects are most important but at the same time it is still a challenge; to extract such predictor variables from a huge catalogue of urban socio-economic and environmental indicators elaborated by many studies for different landscape types and scales; to derive relevant digital and spatially explicit data as model input to calculate the effects of land use (change) and; to validate the model results at the city and the quarter level (scale) as well as to prove the response of the (gained/released) ecosystem service (environmental quality) at the city and at quarter level (closing the circle). Here, the author will give some expressive examples showing the derivation of predictor variables for modelling peri-urban growth and inner city shrinkage as well as its effects on water balance, habitat quality (urban green network) and recreational space. Of major interest is the approach of how to tackle the problem of urban shrinkage in spatially explicit land use (change) modelling (Haase et al. 2004).

Opacuincola gretathunbergae Verhaegen & Haase 2021, sp. nov.
No full textOpacuincola gretathunbergae sp. nov. urn:lsid:zoobank.org:act: FCAB414F-A55A-4819-AFE1-CE2AF78D6B2F Figs 4 E–F, 5 D–E, 6 D, 8 C, 11 B, 12; Tables 1–2 Diagnosis The new species is most similar to Op. ngatapuna in terms of shape and epidermal pigmentation. It differs from the latter in 11 diagnostic DNA positions, in being much larger and in penial morphology. The penis and penial lobe of Op. gretathunbergae sp. nov. are considerably more delicate. Etymology The dedicatee of this new species is the Swedish teenage climate activist Greta Thunberg. Starting with a single-person school strike and demonstration to save our climate she has sparked the global movement “Fridays for Future” supported primarily by young people and managed to finally get momentum in global politics toward action against climate change after warnings of scientists have been largely ignored for more than 30 years. We wish her and the movement the endurance necessary to keep the pressure up!

FEMALE GENITALIA (n = 2; Fig. 12). Ovary small, simple sac starting> 1.5 whorls below apex, comprising 0.25 whorl and not reaching stomach; renal oviduct first coiling 180° clockwise, then 270° counterclockwise; one distal, large receptaculum seminis lying against anterior area of bursa copulatrix; bursa copulatrix large, globular, extending behind much smaller albumen gland, bursal duct entering anteriorly; ovoviviparous, brooding at least three embryos in pallial oviduct, pallial oviduct as brood pouch with very short albumen gland and large capsule gland, the latter histologically uniform in CT scans. MALE GENITALIA (n = 4). Testis lobate sac, starting ca 0.75 whorl below apex, comprising up to 1 whorl, may reach stomach; vesicula seminalis coils along anterior half of testis; proximal vas deferens inserts close to middle of kidney-shaped prostate, distal vas deferens leaving anteriorly; penis long, slender, continuously tapering, pointed; distinct lobe on right side pointing forward (Fig. 11B). Remarks The sister relationship of Op. gretathunbergae sp. nov. to Op. ngatapuna was fairly well supported (Fig. 2). The average COI p-distance was 0.014 and there were eight type 1 characters in COI and three in 16S (Table 2). Morphologically, the new species is larger. Univariate tests comparing shell dimensions could not be conducted, though, because of the small sample size available for Op. ngatapuna. But the PCA (Fig. 3) and the data in Haase (2008) are clear regarding the size difference. Anatomically, only the male genitalia could be compared because this information is lacking for Op. ngatapuna (Haase 2008). The well-developed eyes indicate that the new species is a true crenobiont.Published as part of Verhaegen, Gerlien & Haase, Martin, 2021, All-inclusive descriptions of new freshwater snail taxa of the hyperdiverse family Tateidae (Gastropoda, Caenogastropoda) from the South Island of New Zealand, pp. 71-96 in European Journal of Taxonomy 731 on pages 86-87, DOI: 10.5852/ejt.2021.731.1205, http://zenodo.org/record/444691

Obtusopyrgus farri Verhaegen & Haase 2021, sp. nov.
No full textObtusopyrgus farri sp. nov. urn:lsid:zoobank.org:act: 2D7008F8-BB41-448D-94AF-969925CECDAB Figs 4 I–J, 5 H–I, 6 F, 8 D, 11 D, 14; Tables 1 – 2 Diagnosis In the new species, the central tooth of the radula has more cusps on the edge and less on the basis than in the only other known representative of the genus, Ob. alpinus. The bursa copulatrix is smaller and more elongate compared to the larger, more globular one in the latter. As a consequence, the seminal receptacle reaches far behind the bursa in Ob. farri sp. nov., whereas in Ob. alpinus it lies entirely against the bursa. These species differ at five diagnostic alignment positions of type 1. Etymology Obtusopyrgus farri sp. nov. is named after Gareth Farr, acclaimed New Zealand percussionist and composer integrating non-European music styles including Maori music into Western classical music resulting in the most fascinating and colorful synthesis of different musical expressions. His alter ego, the drag queen Lilith LaCroix, is also colorful.

Remarks The new species is slightly larger than Ob. alpinus (shell height: Mann-Whitney U-test: z = 2.869, p = 0.004), but in terms of shape, they cannot be distinguished (shell height/shell width: Mann-Whitney U-test: z = 0.764, p = 0.445). The genetic and phylogenetic distinction of both species of Obtusopyrgus was only based on 16S as sequencing of COI failed (Fig. 2). There were five diagnostic characters (Table 2). The well-developed eyes indicate that Ob. farri sp. nov. inhabits epigean waters.Published as part of Verhaegen, Gerlien & Haase, Martin, 2021, All-inclusive descriptions of new freshwater snail taxa of the hyperdiverse family Tateidae (Gastropoda, Caenogastropoda) from the South Island of New Zealand, pp. 71-96 in European Journal of Taxonomy 731 on pages 90-91, DOI: 10.5852/ejt.2021.731.1205, http://zenodo.org/record/444691

This specimen was part of the Godeffroy collection (Godeffroy Nr. 6493) and already missing in 1938 (Weidner 1960). Haase (1887) mentiones that he had several specimens from Gayndah and Rockhampton from the Museum Hamburg and additional specimens from the Museums Dresden and Vienna from Gayndah (presumably sent or sold by the Museum Godeffroy). However, only one specimen had white spots with small setae which he described as typical for his variety “ porosus ”.

Optimizing the configuration of a façade module for office buildings by means of integrated thermal and lighting simulations in a total energy perspective
No full textThe building enclosure plays a relevant role in the management of the energy flows in buildings and in the exploitation of solar energy at a building scale. An optimized configuration of the façade can contribute to reduce the total energy demand of the building. Traditionally, the search for the optimal façade configuration is obtained by analyzing the heating demand and/or the cooling demand only, while the implication of the façade configuration on artificial lighting energy demand is often not addressed. A comprehensive approach (i.e. including heating, cooling and artificial lighting energy demand) is instead necessary to reduce the total energy need of the building and the optimization of the façade configuration becomes no longer straightforward, because non-linear relationships are often disclosed. The paper presents a methodology and the results of the search for the optimal transparent percentage in a façade module for low energy office buildings. The investigation is carried out in a temperate oceanic climate, on the four main orientations, on three versions of the office building and with different HVAC system's efficiency. The results show that, regardless of the orientations and of the façade area of the building, the optimal configuration is achieved when the transparent percentage is between 35% and 45% of the total façade module area. The highest difference between the optimal configuration and the worst one occurs in the north-exposed façade, while the south-exposed façade is the one that shows the smallest difference between the optimal and the worst configuratio
Optimal transparent percentage in façade modules for office buildings in a central Europe climate: a case study in Frankfurt
No full textThe building enclosure plays a relevant role in the management of the energy flows in buildings and in the exploitation of the solar energy at building scale. An optimized configuration of the façade can contribute to reduce the total energy demand of the building. Traditionally, the search for the optimal façade configuration is obtained by analyzing the heating demand and/or the cooling demand only, while the implication of the façade configuration on the energy demand for artificial lighting is often not considered, especially during the first stage of the design process. A global approach (i.e. including heating, cooling and artificial lighting energy demand) is instead necessary to reduce the total energy need of the building. When considering the total energy use in building, the optimization of a façade configuration becomes not straightforward, because non-linear relationships often occur. The paper presents a methodology and the results of the search of the optimal transparent percentage of a façade module for office buildings. The investigation is carried out for the four main orientations, on three "average" office buildings (with different surface-area-to-volume ratio), and with different HVAC system's efficiency, located in Frankfurt. The results show that the optimal configuration, regardless of the orientations and the surface-area-to-volume ratio, is achieved in an "average" office building when the transparent component of the façade module is between 35% and 45% of the total façade module surface. The north-exposed façade is the one that presents the highest difference between the "optimal configuration" and the worst one, while the south-exposed façade is the one which suffers less in case of the "worst" configuratio
