Van Soest-nummer
No full textWederom meenden wij er goed aan te doen een speciaal nummer samen te stellen, dit maal ter gelegenheid van de 80e verjaardag van Prof. Dr. Ir. J. L. van Soest.
Diverse auteurs zijn gevraagd om voor dit nummer een bijdrage te leveren over een onderwerp, dat vooral de belangstelling van de jarige geniet. Het verheugt ons, dat zovelen aan ons verzoek hebben voldaan. Daarom zijn wij in staat om naast de („botanische”) levensbeschrijving en bibliografie van de jarige in chronologische volgorde diverse publicaties aan te bieden over onderwerpen, die door Van Soest ook zijn bestudeerd. Via de Flora van Arnhem, waarmee Van Soests lange reeks van publicaties feitelijk een aanvang nam en die de inleiding vormde tot de voor iedere botanische veldwerker bekende indeling van Nederland in plantengeografische districten, komen we bij de Composietengeslachten Hieracium en Taraxacum, aan welk laatste genus de naam van Van Soest onverbrekelijk blijft verbonden
Mycale (Oxymycale) klausjanusorum Van Soest 2018
No full textMycale (Oxymycale) klausjanusorum Van Soest, 2018 Figs 106 a–j Mycale (Oxymycale) klausjanusorum Van Soest, 2018: 50, figs 1–3. Material examined. Holotype ZMA Por. 09452, Indonesia, Flores Sea, SW Salayar, E of Bahuluang, 6.485°S 120.45°E, depth 295–300 m, rectangular dredge, coll. J. van der Land, Indonesian-Dutch Snellius II Expedition, stat. 217, 12 October 1984. Paratypes (detached fragments) ZMA Por. 09459, same data as holotype. Summary description. The species has been recently erected in a separate paper (Van Soest 2018), but for completeness sake its properties are here summarized, including a summary illustration. For more extensive illustrations see Van Soest 2018. Shape (Fig. 106a) semiglobular, white (preserved), markedly hispid encrustations of up to 2 x 1 x 1 cm on calcareous rubble. Consistency firm. Choanosomal skeleton (Fig. 106b) strongly plumose, with thick tracts (500–600 µm diameter) fanning out close to the surface into thinner tracts carrying the tangential ectosomal skeleton. This tangential surface skeleton is penetrated by strongly developed bouquets of long megascleres crowning the subectosomal tracts. Spicules include longer substylostyle megascleres (Figs 106c,c 1), 992– 1175 x 19–22 µm, making up the surface bouquets, but also occurring in the choanosomal tracts, shorter oxeote megascleres (Figs 106d,d 1), 522–732 x 14–20 µm, concentrated in the tangential ectosomal skeleton, but also occurring in the choanosomal tracts, microscleres consisting of three categories of anisochelae, I (Fig. 106e) 152–189 µm, II (Fig. 106f) 33–57 µm, III (Fig. 106g) spurred, 21–29 µm, the largest occurring in subectosomal rosettes, two categories of sigmas, I (Fig. 106h) 33–54 µm, II (Fig. 106i) 16–27 µm) and trichodragmata (Fig. 106j) 24–107 µm. Distribution and ecology. Indonesia (Flores Sea), 300 m depth. For differences with the northern Pacific Mycale (Oxymycale) koreana (Sim, 1982) and M. (O.) rhoi (Sim & Lee, 1998), and with Western South African M. (O.) stephensae Samaai & Gibbons, 2005, see Van Soest (2018). Additional species of Mycale (Oxymycale) reported from the region There are no definite additional Mycale (Oxymycale) species present, as neither Oxymycale stecarmia De Laubenfels, 1954: 93, nor Oxymycale strongylophora De Laubenfels, 1954: 94 were found to be members of the subgenus after re-examination of fragments of the types. Oxymycale stecarmia (type USNM 22890) from SW Ponapé (approx. 6.94°N 158.28°E) is a semi-encrusting sponge specimen of 2 x 4 x 1 cm, of which the skeleton is a haplosclerid reticulation of mucronate oxeas 150–185 x 4 µm in size. The skeleton is largely unispicular, but there are primary tracts of up to 3 spicules in diameter, with little binding spongin, without microscleres. Overall it is Haliclona -like, but on the surface there are small clumps of Mycale spicules, including ‘normal’ anisochelae of 47–51 µm, two size classes of cleistochelae 16–23 µm and 12– 15 µm, sigmas of 22–30 µm, and a few toxodragmas of 50–52 µm. We conclude that this ‘species’ is predominantly a Haliclona spec. with just some contamination from a nearby growing Mycale (Naviculina) aff. cleistochela. Oxymycale strongylophora (type USNM 22937, cf. also Fig. 78f above) from Ailing-lap-lap Atoll (7.3817°N 168.7667 E) is in all described aspects a typical Mycale (Mycale) grandis ‘red’: a red-orange massive sponge, with a dense layer of ectosomal mycalostyles and thick choanosomal megasclere tracts, mycalostyles with both blunt and more sharply pointed endings, 468–576 x 11–17 µm, typical grandis anisochelae I 121–141 µm (see above Fig. 81d), a few anisochelae Ib 71–89 µm, anisochelae II 25–29 µm, spurred anisochelae III 15–19 µm, sigmas I 45–59 µm (NOT: 120 µm, we did not find such sigmas in our fragment), sigmas II 17–19 µm, and abundant fusiform trichodragmas 25–52 x 7–9 µm. There is little doubt that this is a typical specimen of the wide-spread Mycale (Mycale) grandis ‘red’. Global diversity and distribution of the subgenus Mycale (Oxymycale) We queried the World Porifera Database (Van Soest et al. 2020) and added the above results from our Indo-West Pacific Mycale (Oxymycale) study to arrive at the current tentative estimate of known accepted species, which numbers 10. Their distribution over the world oceans summarized as the numbers of species found in Marine Ecoregions of the World (cf. Spalding et al. 2007) is presented in Fig. 107. One species, M. (O.) renieroides (Schmidt, 1870), is dubious (cf. question mark in Fig. 107). The subgenus is circumglobal, but its distribution is erratic, due no doubt to its likely non-monophyly (cf. Van Soest 2018). Subgenus Mycale (Paresperella) Dendy, 1905 Paresperella Dendy, 1905: 162; Whitelegge 1907: 487; Burton, 1937: 26; Lévi 1963: 13; Bergquist & Fromont 1988: 24.

No full textIn dit proefschrift wordt de behandeling beschreven van zeven
autistische kinderen die v66r de behandeling op een ..zeer . laag ontwikkelingsniveau functioneren. Ruim 80% van de autischtische kinderen bereikt volgens onderzoekers niet eens het ontwikkelingsniveau van een anderhalf tot tweejarig kind. Daarom worden de meeste autistische kinderen aangetroffen bij diepzwakzinnigen.

Description Encrusting sponges with an uneven surface (Fig. 9A), with slightly raised oscules (Fig. 9A 1). One (ZMA 01225, Fig. 9A) encrusts the base of an octocoral. Greyish beige in alcohol. Lateral size up to 2 × 1 cm, thickness 3–4 mm, oscules 2 mm in diameter. Consistency soft. SKELETON. Confusedly Haliclona -like, with paucispicular primary tracts interconnected by single oxeas. Special surface reticulation lacking. No visible spongin. OXEAS (Fig. 9 B–B1). Sharply pointed, straight, in a narrow size range, 198– 214 –238 × 4– 6. 4 –11.5 μm. FLAGELLOSIGMAS (Fig. 9 C–E). Circular to ovoid in shape, in two size categories. Larger ones (Fig. 9 C– D) with rather short but distinctly upturned long endings (Fig. 9C 1), both large and small ones with gradually widely curved short endings (Fig. 9C 2, E). Large flagellosigmas (I), with length of long endings 69– 84 –98 μm, short endings 51– 54 –63 μm, widths 53– 66 –83 μm, thickness 1.5– 1. 7 –2 μm. Small flagellosigmas (II) (Fig. 9 E–F), with length of long endings 27– 42 –66 μm, short endings 16– 24 – 34 μm, widths 18– 29 –39 μm, thickness 0.5– 0. 8 –1.5 μm. NORMAL SIGMAS (Fig. 9 G–H). The most common microscleres, occurring in two distinct size classes, the larger ones (I) (Fig. 9G) with rather sharply bent endings, robust, 57– 71 –81 × 1.5– 2. 4 –3 μm, the smaller thinner ones (II) (Fig. 9H) incurved more roundedly, 14– 22 –32 × 0.5– 0. 6 –1 μm. Distribution and ecology Indonesia: Aru Islands, Tana Djampea (island south of Sulawesi), Ambon, Sumba (Marine Ecoregions Arafura Sea, Banda Sea, Lesser Sunda), coral reefs and sand bottoms at 12–125 m depth. Remarks The specimens described here are judged to be conspecific with Gellius incrustans Hentschel, 1912. However, data provided by Hentschel do not entirely match the present specimens: normal sigmas are described as very common, but no size categories were mentioned; only the largest size is quoted as 43– 56 μm, smaller than the present 57–81 μm. Flagellosigmas are quoted as having a largest ‘Durchmesser’ of 47–51 μm, likewise smaller than in the present specimens. Oxeas were 156–180 × 5–6 μm, according to Hentschel. It remains to be established whether the differences observed here are the result of a less than optimal description by Hentschel, or a genuine difference, in which case the present specimens belong to an undescribed species. Apart from these differences, transferring Gellius incrustans to the combination Haliclona (Flagellia) incrustans, created a junior secondary homonym of Haliclona foraminosa incrustans (Czerniavsky, 1880) (originally Protoschmidtia foraminosa forma incrustans) and of Haliclona simulans incrustans (Carter, 1887) (Carter 1887: 70, originally Isodictya simulans var. incrustans). Burton (1959b: 220) already solved the latter case of homonymy by giving Carter’s subspecies the new name Haliclona carteri Burton, 1959. Here the new combination Haliclona (Flagellia) hentscheli nom. nov. is proposed to solve the homonymy with Czerniavsky’s (1880) species, which, in spite of its unrecognizable description remains a senior secondary homonym until such time as its status is resolved. Future reallocation of these species to other valid genera will require reinstatement of Hentschel’s and Carter’s names. Burton’s (1928) deep-water record of Gellius flagellifer from the nearby Andaman Sea was possibly the present species, as the upper size of the normal sigmas falls within the variation of the above measurements. However, the oxeas of the Andaman specimens are 280–360 × 12–14 μm, well in excess of those measured above. Combined with the deepwater occurrence (300–900 m) the conspecificity appears doubtful.Published as part of Van Soest, Rob W.
