NOTES ON ANNOSA SPECIES-GROUP OF HELINA R.-D. （DIPTERA： MUSCIDAE） IN CHINA

The genus Helina R.-D., 1830 is the second largest genus in Muscidae. By now,more than 400 species are known in the world and about 200 species have been described in China. This paper outlines earlier studies on the subgenus and species-group of Helina. Helina annosa species-group is erected. A key to the known Chinese subgroups and species is given.The 19 known Chinese species is listed, including one new species, i.e. Helina setipostitibia sp. nov. Type specimen of the holotype of the new species is deposited in the Institute of Entomology, Shenyang Normal University.     

Animal personality and the ecological impacts of freshwater non-native species

While the ecological impacts of invasive species have been demonstrated for many taxonomic groups, the potential effects of behavioural variation among nonnative individuals （i.e. personality） on these impacts have been largely overlooked. This is despite the fact that recent studies have demonstrated that, by nature, the three first stages of biological invasions （i.e. transport, establishment and spread） can lead to personalitybiased populations. Freshwater ecosystems provide a unique oppor tunity to investigate this issue, notably because the ecological impacts of nonnative species have been extensively documented and because animal personality has been widely studied using freshwater model species. Here, we aim at developing some per spectives on the potential effects of animal personality on the ecological impacts of freshwater nonnative species across levels of biological organizations. At the individual level, personality types have been demonstrated to affect the physiolo gy, metabolism, life history traits and fitness of individuals. We used these effects to discuss how they could subsequently impact invaded popula tions and, in turn, recipient communities. We also discussed how these might translate into changes in the structure of food webs and the functioning of invaded ecosystems. Finally we discussed how these perspectives could interact with the management of invasive species .

会议报道:北京生物入侵国际研讨会:2004年6月6日-11日

Scientists and policy-makers are now well aware of the ecological and societal problems associated with the introduction of species by humans across natural barriers to dispersal. Some introduced species spread abundantly in their new habitats and have negative effects on existing species, both agricultural and natural. Such introduced,invasive species can alter fire, nutrient, and hydrological regimes and have large economic costs.

A New Species of Muscicapa Flycatcher from Sulawesi,Indonesia

The Indonesian island of Sulawesi, a globally important hotspot of avian endemism, has been relatively poorly studied ornithologically, to the extent that several new bird species from the region have been described to science only recently, and others have been observed and photographed, but never before collected or named to science. One of these is a new species of Muscicapa flycatcher that has been observed on several occasions since 1997. We collected two specimens in Central Sulawesi in 2012, and based on a combination of morphological, vocal and genetic characters, we describe the new species herein, more than 15 years after the first observations. The new species is superficially similar to the highly migratory, boreal-breeding Gray-streaked Flycatcher Muscicapa griseisticta, which winters in Sulawesi; however, the new species differs strongly from M. griseisticta in several morphological characters, song, and mtDNA. Based on mtDNA, the new species is only distantly related to M. griseisticta, instead being a member of the M. dauurica clade. The new species is evidently widely distributed in lowland and submontane forest throughout Sulawesi. This wide distribution coupled with the species'' apparent tolerance of disturbed habitats suggests it is not currently threatened with extinction.

Newly arrived or previously overlooked: is there evidence for climate-driven changes in the distribution of molluscs in the Barents Sea?

In recent years, there have been frequent reports of invertebrate species newly recorded from particular areas of the Northeastern Atlantic, and it has often been suggested that these are the result of changes in species ranges due to recent warming. These suggestions make three assumptions: (1) that we have a good knowledge of the fauna of these areas; (2) that new records of “southern” species are more frequent than new records of “northern” species; (3) that climate change is the only factor affecting species range. I tested these assumptions on published records of 30 benthic molluscan species which have been found alive for the first time in the Russian part of the Barents Sea since 2006. Some of the discussed species are warm-water species and may have extended their ranges northward in response to climate change. However, our baseline knowledge of the molluscan fauna of this area before 2006 is limited by the frequent lack of molluscan specialists to study the available material, by the frequent lack of detailed publication and by changes in sampling and processing methods. New records of “southern” species are in fact not significantly commoner than new records of “northern” species. Also reasons other than climate change for observed changes in species distribution should be considered.

Two new species of the genus Tyrophagus (Acari: Acaridae)

Two new species of Tyrophagus Oudemans, 1924, are described. One species, T. Savasi , has been discovered in several habitats of economic importance. It closely resembles T putrescentiae (Schrank) and T. neiswander Johnston & Bruce. The second, T. rebertsonae , has so far been discovered in only two, soil and tree bark. It differs from other species of Tyrophagus by a number of character. Both new species have pigmented 'eyespots' on the prodorsal shield. A new character used to differentiate these species is the shape of the sclerotized neck of receptaculum semins.
The position of the new species in three commonly used keys to adults of the genus Tyrophagus is indicated     

A contribution to the rust flora (Uredinales) on Aizoaceae in southern Africa

Rust fungi on Aizoaceae in southern Africa have been examined and reported based on 27 specimens collected during a biodiversity study and previously collected herbarium specimens. Eight species including five new species have been recognized, and they are described in detail and illustrated. Together with two additional species in literature, ten species of rust fungi are now recognized on Aizoaceae in southern Africa.

New observations on the fine structure of Chrysochromulina strobilus Parke and Manton with special reference to some unusual features of the haptonema and scales

Summary A new isolate of C. strobilus Parke and Manton has been investigated with light and electron microscopy to add significant details not previously studied. With the aid of a ciné record, to be described more fully elsewhere, some of the more important haptonema movements have been accurately timed. With the aid of improved technical methods of electron microscopy, new observations have been made on the haptonema base, and on the structure and mode of origin of the scales. The presence of 6 microtubules (instead of the more usual 7) in the very long haptonema of this species has been confirmed but the elaborate changes in tubule number and arrangement which take place in the haptonema base are shown to be essentially like those of other species. The morphology and arrangement of the two types of scale present on the cell are as previously described though information on several new and taxonomically valuable surface features have been added. The cup-shaped scales in particular are shown to be more different from those of other species now known in the genus than might previously have been recognised. This difference extends to the position of nascent scales within the Golgi system which is described in a preliminary way. Further discussion is deferred until some other new isolates representing related taxa have been described and named.
