Zodarion ericorum Benhalima & Bosmans 2020, sp. nov.
No full textZodarion ericorum Bosmans sp. nov. Figures 61–62, 74–77, 98–101 Etymology. The first author dedicates this species to Eric Gobbers (Gent, Belgium) and Erika Vanden Bergh (Instituut voor Natuur- en Bosonderzoek, Belgium), two Belgian biologists, for helping him collect material during his first trip to Morocco in 1984. Diagnosis. Males are recognized by the large basal knob in the tegulum, which is absent in other species or only poorly developed in Z. jeanclaudeledouxi sp. nov. Females are distinguished by the shape of the transverse oval pit in the epigyne, which is not the same in all other species. Description. Measurements. Male (n=4): total length 2.4–3.8; carapace 1.30–1.57 long, 0.90–1.1 wide. Female (n=7): total length 3.8–5.5; prosoma 1.76–3.4 long, 1.25–2.49 wide. Colour (Figs 61–62): carapace dark reddish brown to black, posterior part sometimes yellowish orange of variable size; coxae pale yellowish, femora dark brown to black, basal part white; tibiae brown to pale brown, with paler stripes laterally; metatarsi yellowish brown, base often infuscated; tarsi yellowish brown; abdomen in male with scutum, dark sepia, dorsally with two triangular spots and one oval postero-median spot whitish, in some specimens triangular spots absent; venter and oblique lateral stripe whitish. Female as male, but abdomen without scutum. Eyes: AM=1 (0.13); AL=0.78; PM=PL=0.67; a=0.67; b=0.23; c=1.56; d=0.33; MOQ: AW=0.88PW; L=0.81PW. Male palp (Figs 74–77): tibial apophysis elongated, proximal part nearly rectangular and straight, distal part curved in postero-dorsal direction, terminally rounded; retrolateral margin of cymbium with indentation; tegulum with rounded knob at its base; median apophysis with broad base, rectangular, distal part having the form a bird’s beak; tip of embolus slender, terminally curved in antero-prolateral direction. Epigyne (Figs 98–101): with large, transverse, oval pit, somewhat more than 2 times as wide as high, posterolaterally acccompied by semi-circular pockets; spermathecae small, separated by more than 3 diameters.

Precession- and Obliquity-Induced Changes in Moisture Sources for Enhanced Precipitation Over the Mediterranean Sea
No full textEnhanced winter precipitation over the Mediterranean Sea at times of minimum precession and maximum obliquity, that is, times of enhanced insolation seasonality, could provide freshwater required to form orbitally paced sedimentary cycles across the Mediterranean, offering a possible alternative to monsoonal runoff. We investigate the sources of the enhanced winter precipitation, by applying a moisture tracking model on the results of idealized orbital extreme experiments with a state-of-the-art climate model. Precession and obliquity enhance precipitation in fall and winter. Our study shows that the source of enhanced precipitation over the Mediterranean Sea differs during the winter half-year. In fall, the majority of the precession-induced precipitation increase originates from the Mediterranean itself. However, in late winter, the increase can be attributed to enhanced moisture advection from the Atlantic. This agrees with changes in evaporation and air-sea temperature differences over the Mediterranean. The obliquity-induced precipitation increase shows much less differences, with an equal contribution of local and Atlantic sources. The mechanism behind the Atlantic source of moisture, particularly important in late winter for precession-induced precipitation changes, is related to a weakened Azores High and slightly higher surface pressure over North Africa. The resulting anomalous circulation patterns generate enhanced Atlantic moisture transport toward the Mediterranean. These mechanisms coincide with weaker storm track activity over the North Atlantic, opposite to previous studies that often attribute enhanced Mediterranean winter precipitation to a southward shift and intensification of the Atlantic storm track. We thus provide an alternative mechanism for Atlantic sources of orbitally paced Mediterranean precipitation changes.Water Resource

Monsoonal response to mid-holocene orbital forcing in a high resolution GCM
No full textIn this study, we use a sophisticated high-resolution atmosphere-ocean coupled climate model, EC-Earth, to investigate the effect of Mid-Holocene orbital forcing on summer monsoons on both hemispheres. During the Mid-Holocene (6 ka), there was more summer insolation on the Northern Hemisphere than today, which intensified the meridional temperature and pressure gradients. Over North Africa, monsoonal precipitation is intensified through increased landward monsoon winds and moisture advection as well as decreased moisture convergence over the oceans and more convergence over land compared to the pre-industrial simulation. Precipitation also extends further north as the ITCZ shifts northward in response to the stronger poleward gradient of insolation. This increase and poleward extent is stronger than in most previous ocean-atmosphere GCM simulations. In north-westernmost Africa, precipitation extends up to 35° N. Over tropical Africa, internal feedbacks completely overcome the direct warming effect of increased insolation. We also find a weakened African Easterly Jet. Over Asia, monsoonal precipitation during the Mid-Holocene is increased as well, but the response is different than over North-Africa. There is more convection over land at the expense of convection over the ocean, but precipitation does not extend further northward, monsoon winds over the ocean are weaker and the surrounding ocean does not provide more moisture. On the Southern Hemisphere, summer insolation and the poleward insolation gradient were weaker during the Mid-Holocene, resulting in a reduced South American monsoon through decreased monsoon winds and less convection, as well as an equatorward shift in the ITCZ. This study corroborates the findings of paleodata research as well as previous model studies, while giving a more detailed account of Mid-Holocene monsoons

The species has never been cited since then and the type material was not examined. The description is accompanied by good illustrations of the epigynum in ventral and lateral view, which allowed Telfer <i>et al</i>. (2003) to identify females collected in Tapada de Mafra as <i>L. bacelarae</i>. The females were accompanied by the unknown male and this allows us to describe it and classify the species in one of the new genera that recently have been created for species previously placed in <i>Lepthyphantes</i>. The male palp (Fig. 57) appears to be very similar to the one of <i>Lepthyphantes obscurus</i> (Fig. 64), in having a cymbium with a conical tubercle and an elongated lamella. The epigynum also shows corresponding characters: the absence of lateral lobes and the short insemination ducts. <i>Lepthyphantes obscurus</i> is the type species of the genus <i>Obscuriphantes</i> and <i>Lepthyphantes bacelarae</i> is hereby transferred to <i>Obscuriphantes</i>.</p> <p> The first author was also able to examine the type material of <i>Lepthyphantes ollivieri</i> described by Denis (1957) from the French Pyrénées, only known from the female.

Agraecina lineata Simon
No full textAgroeca lineata Simon 1878: 308 (descr. female). Agraecina lineata Simon 1932: 939, 970 (descr. male, non female); Grimm 1986: 14. Diagnosis: Males are easily distinguished from other liocranids from the Maghreb by the strongly pointed tibial apophysis and median apophysis of the bulb; females have an epigyne with elongate median septum, without other chitinisations. Remarks: Simon (1878) described Agraecina lineata from a juvenile or subadult female from Corsica. He described the male and female in 1932, and the species was said to occur in continental France, Corsica, Algeria and Morocco. Simon’s Fig.ure of the female epigyne is incorrect, as also indicated by Grimm (1986). The same author presented recent Fig.ures of the male palp, epigyne and vulva have never been illustrated. , Description: Measurements: Male: Total length 4.4-6.0; carapace 1.97-2.82 long, 1.64-2.21 wide. Female: Total length 8,0; carapace 2.72 long, 2.21 wide. Colour: Carapace yellowish brown with grey margin and anastomosing, radiating stripes; legs yellowish brown, not annulated; abdomen pale grey with wide median and narrower lateral longitudinal grey stripes, converging to the back. Palp (Figs. 17-18): Tibial apophysis strongly pointed, gradually narrowing, oblique to the axe of the segment: median apophysis gently curved, distal 2/3 linear and pointed; embolus straight, needle-like. Epigyne (Fig. 19): With hardly defined, short median septum in the anterior half, in the postero-median half with gently curved spermathecae visible in transparency.

Politieke cultuur tussen cultuurgeschiedenis en politieke geschiedenis
No full textH. te Velde, Stijlen van leiderschap. Persoon en politiek van Thorbecke tot Den Uyl
Jac Bosmans, The political culture between political history and the history of civilization
In principle, the author agrees with Te Velde's choice of Thorbecke, Kuyper, Colijn, Drees and Den Uyl as examples of styles of policy-making which, with the benefit of hindsight, seem to be an apt expression of the political spirit of their days, though he does place a few question marks against the choice of Colijn and Drees. In addition, he advocates the establishment of a mutually beneficial co-operative relationship between tfiose political historians who focus in particular on investigating the cultural aspects of politics and those who are more interested in examining the actual results. He argues that this kind of co-operation is necessary in order to withstand the tendency of many cultural historians to claim almost the entire past as the focus of their research, a claim which leaves no room for political history as a separate field of study.
This review is part of the discussion forum 'Stijlen van leiderschap' (H. te Velde)
