HighlightIdentification of Morphological characteristic of the Bolbosoma sp.Genetic confirmation of the specific species of Bolbosoma turbinella.The first report in Straits of Malacca.Health status of Sei Whale (Balaenoptera borealis).AbstractThe study of ectoparasite and endoparasites of marine mammals are not habitually done because some species are endangered and protected by law. A stranded Sei Whale, Balaenoptera borealis (Anderson, 1878) from the East Coast of Peninsular Malaysia was examined for endoparasites. The objective of this study is to identify the species of acanthocephalan in the intestine of the Sei Whale found in the straits of Malacca. A total of ten parasite specimens were collected from the fresh intestine, and were fixed in 10% buffered formalin for further histological procedures. The morphological features of this parasite viewed under Scanning Electron Microscope (SEM) are referred to as the proboscis armature and variations in the spination of the area between the anterior and posterior cephalic bulb. Genomic DNA extracted by using QIAGEN DNeasy Blood & Tissue Kit DNA and sequenced with First Base Sequencer showed that this species belonged to Bolbosoma turbinella. This was the first record of a sei whale carrying the endoparasites Bolbosoma turbinella, in Malaysian waters.

A sample of goji leaves with blisters was brought from a private garden in Vyšná Kamenica to the Botanical Garden of Pavol Jozef Šafárik University in Košice to identify the problem. The respective plant (Lycium chinense Miller cv. Big Berry) was bought through the internet and these distortions occurred after some time during cultivation. The mites found on the deformed leaves were examined using a light microscope and a scanning electron microscope (SEM) as well. The identity of Aceria kuko (Kishida, 1927), the goji berry gall mite, was confirmed. Other available possible host plants in Košice and the surroundings were checked with no positive findings. However, typical foliar galls on goji plants have been indirectly observed (through the television) in Malinovo near Bratislava. Due to the risk from this mite species not only to the goji (Lycium sp.) but also to the pepper (Capsicum annuum Linnaeus) and some other Solanaceae plants, the respective authorities of the Slovak phytosanitary service were informed.

Fossil conifers from the Early Cretaceous, most likely late Aptian, Crato Formation were studied. The excellent preservation of several of those fossils allowed detailed investigations of the leaf epidermis by light microscope (LM) and by scanning electron microscope (SEM). Members of two conifer taxa were recognized: The Araucariaceae are represented by a female cone of cf. <i>Araucaria</i> spec. A juvenile cone (<i>Araucariostrobus spec.</i>) and sterile foliage shoots of <i>Brachyphyllum obesum might</i> be attributed to the Araucariaceae as well. The morpho-genus <i>Lindleycladus</i> (incertae sedis) is represented by foliage shoots. The occurrence of <i>Lindleycladus</i> is the first record of this extinct morpho-genus in the Southern Hemisphere. Anatomical features of these conifers are interpreted as adaptations to a warm seasonally dry climate. Taphonomic problems concerning these conifer remains are discussed. <br><br> Fossile Koniferen aus der unterkretazischen, höchstwahrscheinlich oberaptischen Crato Formation wurden untersucht. Die ausgezeichnete Erhaltung einiger Exemplare gestattete die Analyse von Blattepidermen mittels Licht- und Rasterelektronen-mikroskop. Vertreter zweier Koniferentaxa wurden nachgewiesen: Araucariaceae kommen mit einem weiblichen Zapfen von cf. <i>Araucaria spec</i>. vor. Ein juveniler Zapfen (<i>Araucariostrobus spec</i>.) und sterile Zweige mit der Beblätterung der Morpho-Species <i>Brachyphyllum obesum</i> werden unter Vorbehalt ebenfalls zu den Araucariaceae gestellt. Vegetative Organe der Morpho-Gattung <i>Lindleycladus</i> (incertae sedis) sind ebenfalls erhalten. Das Vorkommen von <i>Lindleycladus</i> ist ein erster Nachweis dieser fossilen Morpho-Gattung in der Südhemisphäre. Anatomische Merkmale dieser Koniferen werden als Anpassungen an ein warmes, saisonal trockenes Klima gedeutet. Im Zusammenhang mit den Koniferenresten werden taphonomische Probleme diskutiert. <br><br> doi:<a href="http://dx.doi.org/10.1002/mmng.20040070109" target="_blank">10.1002/mmng.20040070109</a>

Two new species of Melitoid amphipods from Pulau Perhentian Besar and Pulau Tinggi, east coast of Peninsular Malaysia were described and illustrated. Specimens were collected by means of an airlift suction sampler at seagrass areas of the two islands. Ceradocus mizani sp. nov. found commonly at seagrass areas of Malaysian waters, can be readily distinguished from any other known Ceradocus species by a set of distinct characters based on the asymmetrical male gnathopod 2; sculpturing on the palm of the larger gnathopod 2; serrated pleonal epimeron 1–3; and multidentate dorsal pleonites and urosomites with 11 spines on urosomite 1 and 6 spines on urosomite 2. Victoriopisa tinggiensis sp. nov. on the other hand is characterized by its prolonged lateral cephalic lobe; the presence of an anteroventral notch on the head; weakly developed eyes; and pereopod 7 basis with intermediate lobation. This would be the first record of the genus Ceradocus and Victoriopisa from the waters of Peninsular Malaysia. Discovery of these two new species represents an ongoing and continuous effort on amphipod taxonomical studies here in Malaysia.

Four species of sea horses (Syngnathidae: Hippocampus) were found in Peninsular Malaysia during a survey conducted between April and August 2001. These were Hippocampus trimaculatus, H. spinosissimus, H. kuda and H. kelloggi. All four species were found in the Straits of Malacca; two species (H. trimaculatus and H. spinosissimus) in the east coast of Peninsular Malaysia in the South China Sea; and three species: H. trimaculatus, H. spinosissimus and H. kuda in the south coast, Straits of Johor. There were habitat and depth separations by species. Hippocampus trimaculatus, which was found throughout the coastal waters of the Peninsular, were reported to inhabit chiefly among gorgonians at approximately 20–40 m depth. The habitat and depth in H. spinosissimus were rather similar to that of H. trimaculatus; but the former species was less widespread in the west coast. Hippocampus kuda was confined to shallow water between 1 to 3 m, and was found in seaweeds and sea grass meadows in a few estuaries; whereas H. kelloggi inhabited gorgonians and sea whips in deep-water below 65 m. Mean standard lengths are given. No sexual size dimorphism was detected in any of the species.

Lepidii seu Descurainiae Semen, the dried ripe seeds of Descurainia sophia (L.) Webb ex Prantl or Lepidium apetalum Willd., is used widely as a traditional herbal medicine in Northeast Asia. However, seeds of a number of other species have been misidentified as Lepidii seu Descurainiae Semen, and are therefore misused because of morphological similarities among the seeds of these species. To accurately identify Lepidii seu Descurainiae Semen, we investigated the morphology, mucilage reaction, and micromorphology of Lepidii seu Descurainiae Semen and the seeds of other plant species. We used a stereomicroscope and a scanning electron microscope to describe and compare various morphological and micromorphological characteristics of seeds, and a light microscope to determine the presence or absence of mucilage. We evaluated the potential usefulness of mucilage as a morphological marker for seed identification. The shape, outline, and size of seeds were useful characteristics for identification. The mucilage reaction and the three types of seed ornamentation that were identified in this study were particularly valuable for seed authentication. Based on these results, we created an identification key based on morphology and micromorphology of Lepidii seu Descurainiae Semen and adulterant seeds. The method of seed identification using microscopic examination, as described here, is easy and economical, making it a potential key tool for accurate identification of Lepidii seu Descurainiae Semen and seeds of other medicinal plants.

Scanning electron microscopic studies (SEM) revealed that the radula of Muricanthus kuesterianus resembled that of Muricanthus virgineus in most details. But there were some apparent differences. In Muricanthus kuesterianus rachidian tooth have a broad base than that of Muricanthus virgineus. The base of the median cusp was broad, short, stout and pointed straight towards the anterior end. The left  lateral cusp elongated,  sharp, slightly bent and pointed outwards and the right lateral cusp dorso ventrally flattened and the anterior end small, slightly pointed. In between the median and left lateral cusps, a sharp and pointed denticle is present where as the right laterals and median cups there is no denticle. The lateral teeth which are two in numbers flanked median rachidian.Keywords: Scanning Electron Microscope, Radula, Gastropoda, Muricidae, Muricanthus kuesteianus,
