The Agromyzid genus Paraphytomyza Enderlein: new to the Oriental Region (Diptera)

Paraphytomyza jasmini sp. n. from India and P. loniceroides sp. n. from N.W. Pakistan are described, representing the first reared species in this genus known in the Oriental Region. P. kraussi (Sasakawa, 1963) from Papua New Guinea is formally transferred to Paraphytomyza as a new combination. The nomenclature, distribution and host range of Paraphytomyza are discussed.     

Strategies for size and growth in butterflies (Insecta: Lepidoptera): counterintuitive trends and unique solutions to achieving maturity

Larger organisms are expected to take longer to develop, depressing overall growth rates. An examination of relationships between size, development times and growth rates in British and northwest European butterflies has revealed a reversal of this relationship with large species developing rapidly and small species developing slowly, especially in subsets of species that complete their development in a single season and have multiple broods. Distinctive life history associations are found to be linked to rapid development (daytime and gregarious feeding) and enhanced defence (larval spines, aposematism) from the resulting increased exposure to enemies. Taxonomic bias is evident in development-size patterns linked to overwintering strategy and voltinism. Different strategies exist for faster growth in the larger Pieridae and non-satyrine Nymphalidae. Larval host plant contrasts for food quantity and quality underlie distinctions for size and development times.

Spatial patterns of ephemeral plants in Gurbantünggüt Desert

In the present research, the authors measured parameters of richness, cover and importance value of ephemeral and ephemeroid plants on south-north and east-west transects in the Gurbantünggüt Desert in early spring, and investigated and analyzed the microhabitats, such as terrain, geomorphology, soil physical-chemical properties and crusts. By comparison, the regional differences in the ephemeral distribution in the desert were revealed. The species of ephemeral plants in the south and center are the richest and those in the west are the poorest in the desert. The cover of ephemeral plants in the mid-south is higher than that in the north, and that in the mid-east is higher than that in the west. The response of ephemeral plants to the spatial variation of the desert habitat forms the population-habitst gradient of ephemeral plants. The characteristics are： （1） In the habitat with higher terrain, coarser textured soil with poorer sorting and correspondingly higher organic matter and lower alkali-saline contents, Carex physoides and Eremopyrum orientale are the dominant ephemeral plants; （2） In the dry habitat with lower terrain, looser textured soil, some organic matter, alkali-saline soil, and developed crust, the ephemeral plants Alyssum linifolium and Erodium oxyrrhynchum are of characteristic of drought and alkali-saline tolerance; （3） In the habitat with lower terrain, some water and more alkali-saline soil, the ephemeral plants Neotorularia torulosa and Hypecoum parviflorum being of alkali-saline tolerance are mainly developed. However, most ephemerals are distributed in a habitat order of higher terrain, some organic, and less alkali-saline soil on the above-mentioned ephemeral population-habitst gradient. The spatial gradient of variation in desert microhabitsts is small, and as a whole, the physiological character of mesophytism is represented by the desert ephemerals.
