日本菟丝子寄生菌致病力的专化性研究

日本菟丝子(Cuscuta japonica)吸取不同寄主植物的营养,经过营养代谢其机体内的过氧化物酶同工酶的活性或酶带数发生变化,从而改变了它对胶孢炭疽菌菟丝子专化型[Col-letotrichum gloeosporioides(Penz.)Sacc.f.sp.Cuscutael]同一菌株的抗性,以此为依据,采用寄生在不同植物上的日本菟丝子做为鉴定寄主,可以鉴别出胶孢炭疽菌菟丝子专化型中不同菌株的致病力差异。 初步认为:龙眼、桂花、柚子和冬青上的紫色菟丝子及泡桐、桂花和冬青上的黄色菟丝子可以作为鉴定寄主。     

芥蓝田主要害虫种群生态位研究

2001年秋季在福州郊区对芥蓝田BrassicaalboglabraBailey害虫种群的生态位进行了初步研究,研究结果表明:蚜虫、粉虱和小菜蛾为秋季芥蓝田的优势种害虫,菜青虫、黄曲条跳甲和斑潜蝇为随从种害虫。这些主要害虫的生态位在时间、空间维度和时-空二维上存在明显分化,各种害虫对资源的竞争主要集中在对空间资源的竞争,即随着时间的推移,害虫间的竞争主要集中在对植株上可获得的产卵、取食和栖息的空间资源的竞争。

It contains 2 genera, 23 species, 2 varieties and 7 cultivarieties, of which one species is described as new and two are first recorded from China. The Chinese passifloraceous plants are mainly distributed in Yunnan (2 gen. 16 sp.), Guangdong (2 gen. 9sp.) and Guangxi (2 gen. 8 sp.).     

Recent advances in breeding for improving iron utilization by plants

Iron-chlorosis deficiency may occur when an iron-inefficient genotype is grown on calcareous soil. One way to correct the problem is to modify the genotype by plant breeding. Cultivars have been released for oat (Avena byzantina C. Koch), sorghum [Sorghum bicolor (L.) Moench], dry bean (Phaseoulus vulgaris L.), and soybean [Glycine max (L.) Merr.]. Progress is being made in peanut (Arachis hypogea L.), forage species such as clovers (Trifolium sp.) and bluestems (Botriochloa sp.), and pepper (Capsicum annuum L.). Screening of rootstocks is done on citrus (Citrus sp.), mango (Manguifera indica L.), and avocado (Persea americana Mill.).     

Freshwater fish otoliths from the Deccan Trap associated sedimentary (Cretaceous-Tertiary transition) beds of Rangapur,Hyderabad, District,Andhra Pradesh,India

The present paper describes 12 species of fish otoliths recovered by washing and screening processes from the Deccan Trap associated sedimentary (Intertrappean) beds exposed near Rangapur, Hyderabad District, Andhra Pradesh, India. The present collection of otoliths contains four major groups: Clupeomorpha (“Clupeidarum” sp.), Osteoglossomorpha (“Osteoglossidarum” deccanensis sp. nov., “O”. intertrappus sp. nov. and “Notopteridarum” nolfi sp. nov.), Protacanthopterygii (“Salmoniformorum” rectangulus sp. nov.), and Percomorpha (Dapalis sp., “Apigonidarum” ovatus sp. nov., “Serranidarum” sp., “Percoideorum” ellipticus sp. nov., “P.” rangapurensis sp. nov., “Percoideorum” sp. 1 and “Percoideorum” sp. 2). This collection of otoliths represents freshwater lacustrine deposition of the sediments. The age of the Intertrappean beds is considered Uppermost Cretaceous to Palaeoncene on the basis of freshwater ostracode (Paracypretta jonesi, Mongolianella hislopi and Candoniella sp.) and charophyte (Platychara perlata and Nemegtichara sp.) assemblages.     

New spiders in Upper Cretaceous amber from New Jersey in the American Museum of Natural History (Arthropoda: Araneae)

The oldest described fossils of the extant spider family Araneidae (Araneinae; gen. et sp. indet.), the extant genus Orchestina (Oonopidae; O. sp. indet.) and the new fossil genus Palaeosegestria (Segestriidae; P. lutzzii gen. et sp. nov.) are presented from Upper Cretaceous amber of New Jersey. The known fossil range of the extant family Araneidae is extended approximately 50 myr from the previously oldest described araneid from the Middle Eocene oil shales of the Messel pit in Hesse, Germany. The fossil range of the extant genus Orchestina is also extended 50 myr from the previously oldest described specimen in Eocene Baltic amber.     

New species of eocene primates and the phylogeny of European adapidae.

Restudy of virtually all of the important collections of European Eocene primates of the family Adapidae indicates that 28 valid species in 8 genera are now known, spanning a time period of nearly 20 million years. The biostratigraphic distribution of each species has been studied in the context of established reference levels, and a maximum of four evolutionary lineages are known from any one locality. Ten new species are proposed in the genera Pelycodus (1 sp.), Protoadapis (4 sp.), Periconodon (2 sp.), Anchomomys (1 sp.), and Adapis (2 sp.). Phylogenetic relationships among the species, based on stratophenetic linking, are indicated whenever possible.

First records of Gastrotricha from South Africa, with description of a new species of Halichaetonotus (Chaetonotida, Chaetonotidae)

During a survey of the biota of the St. Lucia Estuary in the iSimangaliso Wetland Park, South Africa, a number of Gastrotricha were found among samples of meiofauna. Fresh, marine sediment yielded several specimens belonging to a total of seven species. Of these, two are already known from other regions (i.e., Dactylopodola australiensis and Heteroxenotrichula squamosa), one is described as new to science (Halichaetonotus sanctaeluciae sp. n.), while the remaining four (Pseudostomella sp., Halichaetonotus sp.1, Halichaetonotus sp. 2, Xenotrichula sp.) require further collections and analysis, in order to establish the extent of their affiliation to species already described. General appearance, shape of hydrofoil scale and the occurrence of three long spines on the dorsal side make the new species most closely related to Halichaetonotus australis and Halichaetonotus marivagus. The key differences from these taxa and between Halichaetonotus sanctaeluciae sp. n. and Halichaetonotus aculifer are discussed.
