Comparative studies into two isolates of Alternaria affecting umbelliferae

Summary 1. A new species ofAlternaria isolated from the diseased plants ofCarum copticum L.Peucedanum graveolens Benth. &Hook f. andFoeniculum vulgare Mill. is described and compared with other species affecting Umbelliferae.2. TheCoriandrum isolate described by the writer asAlternaria poonensis Raghunath is a shy sporulator in artificial culture with long beaked muriform spores formed singly at the end of comparatively short conidiophores.3. The isolate from the other three host plantsCarum copticum L.,Peucedanum graveolens Benth. &Hook f. andFoeniculum vulgare Mill. is named asAlternaria umbellifericola sp. nov. and is a profusely sporulating species, forming long chains of spores with rudimentary beak.4. TheCoriandrum isolate (Alternaria poonensis) has a narrower temperature range (25–30° C) than theCarum isolate (20–35° C) for optimum sporulation.5. TheCoriandrum isolate is pathogenic toCarum but not toDaucus carota L.6. TheCarum isolate is pathogenic toDaucus carota but does not infectCoriandrum sativum L.7. TheCoriandrum isolate has a wider host range among the Umbelliferae than theCarum isolate.Part of the M.Sc. thesis submitted to the Poona University, 1964.

Certain chemical requirements for growth and sporulation of alternaria species

Summary Fresh, single-spore isolates ofAlternaria nyctanthi spec. nov. andAlternaria tropaeoli Deshpande &N. R. Rajderkar from the infected leaves varied widely in response when cultured on Coon's, PDA, Richard's and Czapek's medium. Some isolates did not produce macroscopically visible colonies, although the spores germinated. A few isolates grew poorly without sporulating; most of the others grew well and sporulated abundantly on PDA and Czapek-Dox medium.Cultures that had been inhibited from sporulating by irradiation at 26° C sporulated when subsequently placed in a 22° C incubator, even though nitrogen availability was varied by adding solutions of NaNO₃, with or without sucrose.

Four thousand years of vegetation and fire history in the spruce forests of northern Kyrgyzstan (Kungey Alatau,Central Asia)

Analyses of pollen, macrofossils and microscopic charcoal in the sediment of a small sub-alpine lake (Karakol, Kyrgyzstan) provide new data to reconstruct the vegetation history of the Kungey Alatau spruce forest during the late-Holocene, i.e. the past 4,000 years. The pollen data suggest that Picea schrenkiana F. and M. was the dominant tree in this region from the beginning of the record. The pollen record of pronounced die-backs of the forests, along with lithostratigraphical evidence, points to possible climatic cooling (and/or drying) around 3,800 cal year b.p. and between 3,350 and 2,520 cal year b.p., with a culmination at 2,800–2,600 cal b.p., although stable climatic conditions are reported for this region for the past 3,000–4,000 years in previous studies. From 2,500 to 190 cal year b.p. high pollen values of P. schrenkiana suggest rather closed and dense forests under the environmental conditions of that time. A marked decline in spruce forests occurred with the onset of modern human activities in the region from 190 cal year b.p. These results show that the present forests are anthropogenically reduced and represent only about half of their potential natural extent. As P. schrenkiana is a species endemic to the western Tien Shan, it is most likely that its refugium was confined to this region. However, our palaeoecological record is too recent to address this hypothesis thoroughly.     

The first fossil Paussine (Coleoptera: Carabidae) from Mexican amber

Eohomopterus simojovelensis n. sp., the first fossil record of the subfamily Paussinae (Coleoptera: Carabidae) from the Miocene amber of the Simojovel area, Chiapas, Mexico, is described. The morphology of the new species is compared withEohomopterus poinari Nagel, 1997 from Dominican amber as well as with extant representatives ofEohomopterus, and the biogeographical implications are discussed.      

Utilization of oligosaccharides by three imperfect fungi

Summary The utilization of oligosaccharides (maltose, sucrose, lactose and raffinose) by three imperfect fungi viz.Alternaria tenuis Auct.,Colletotrichum capsici (Syd.)Butler &Bisby andColletotrichum gloeosporioides Penz. isolated from diseased leaves of tomato,Scindapsus pictus andPolyscias balfuriana respectively, was studied chromatographically. Except for lactose, all the sugars were utilizzed through a hydrolytic pathway and almost all proved to be a suitable source of carbon for the growth of fungi. Along with the utilization of sucrose, a simultaneous synthesis of an oligosaccharide was also observed in case of two species ofColletotrichum. C. gloeosporioides, however, also synthesized an oligosaccharide, maltotriose if it is grown in the medium containing maltose. During the utilization of raffinose, melibiose and fructose were detectted in the culture medium ofA. tenuis. Melibiose was further broken down into glucose and galactose by the two species ofColletotrichum.All the sugars were consumed from the media within 15 days except for lactose which persisted in the media even after 15 days.     

Vegetation history of the SE section of the Zagros Mountains during the last five millennia; a pollen record from the Maharlou Lake, Fars Province, Iran

A pollen diagram was derived from a 150 cm core taken from the shallow hypersaline Lake Maharlou in the south-eastern part of the Zagros Mountains, SW Iran. The pollen record shows that Quercus brantii woodland and Pistacia–Amygdalus scrub dominated the area during the late Holocene. The record starts at around 5700 cal b.p. with a dry period during which both Pistacia–Amygdalus scrub and Quercus brantii woodland were at their minimum extent. This period was followed by the expansion of Pistacia–Amygdalus scrub in the area and the spread of Quercus brantii woodlands at higher altitudes. An important occupation phase, characterized by the appearance of several cultivated tree species such as Juglans, Olea, Vitis and Platanus, started at ca. 4300 cal b.p., coinciding with the onset of the Bronze Age civilization of Jiroft in Central Iran. Human activities become very clear after 3700 cal b.p. Around 2700 cal b.p., extensive stands of Pistacia–Amygdalus scrub became profoundly degraded, presumably under strong human pressure coinciding with the beginning of the Persian Empires. The maximum expansion of the Quercus brantii woodland occurred about 2100 to 1700 cal b.p. This woodland remained relatively stable until the end of the diagram at 400 cal b.p.
