Diaptomid Copepods

We present an updated checklist of the Diaptomidae of China, based on a literature review and on original field data from all over China during 2012-2016. A total of 19 genera and 56 species have been recorded. Neutrodiaptomus has the highest species richness (10 species), followed by Arctodiaptomus (9 species). Only one species each of Eudiaptomus, Mixodiaptomus, Eodiaptomus, Dentodiaptomus, Dolodiaptomus, Allodiaptomus, Karstodiaptomus, Metadiaptomus and Paradiaptomus was found. The taxonomic status of 16 species was revised: one wrongly attributed genus, Argyrodiaptomus, was corrected to Sinodiaptomus. First records for China include Arctodiaptomus parvispineus and one new cave-dwelling genus, Karstodiaptomus, is added. One Latin name from Shen & Sung’s book (1979) is corrected. Remarks on nomenclature and taxonomic issues are supplemented with information on the geographical distribution of the various species within China.

The diversity, distribution, and checklist of diaptomid copepods from various freshwater ecosystems throughout Thailand are presented, based on data from our biodiversity projects during 1993–2019 and literature reviews. Thailand has one of the most diversified diaptomid fauna in the world, with 42 species identified from 2150 localities (4962 samples). Mongolodiaptomus has the highest species richness with ten species, followed by Tropodiaptomus with seven species. Among these, eight taxa (Arctodiaptomus sp., Mongolodiaptomus pectinidactylus, Neodiaptomus meggitti, Tropodiaptomus hebereri, T. lanaonus, T. oryzanus, T. ruttneri, and Paradiaptomus greeni) are new to the fauna of Thailand. The rare P. greeni, which predominantly occurs in Africa, is also a new record for Southeast Asia. The most frequently encountered species were Mongolodiaptomus botulifer, Phyllodiaptomus praedictus, M. calcarus, M. dumonti, M. malaindosinensis, Vietodiaptomus blachei, Phyllodiaptomus christineae, Eodiaptomus sanoamuangae, Neodiaptomus yangtsekiangensis, E. draconisignivomi, T. vicinus, and Heliodiaptomus elegans. Twelve species appear to be endemic to Thailand, and eight species occur only in the countries belonging to the lower Mekong River Basin (Thailand, Cambodia, Laos, and Vietnam). The uniqueness of the Thai diaptomids is a high degree of co-occurrence of four to seven species in the same localities. Comments on the taxonomic status of the species recorded are provided. In addition, the taxonomic validity of Mongolodiaptomus malaindosinensis is discussed.

The Western Ghats

<p>The diversity of many invertebrate taxa from Western Ghats of Maharashtra remains unknown due to lack of systematic studies. We studied freshwater calanoid copepods from this region, and found eleven species of diaptomid copepods in 180 samples collected from 80 sites in the study area. Most of these are new records for this region. The observed fauna includes Oriental, Gondwanan, Palaearctic and Indian endemic taxa. Locality data for all the observed species, along with notes on some ecological aspects of the sampled sites are provided. Non-parametric estimates of species richness for the region suggested an overall adequacy of sampling effort, and probable missing out of some species from habitats with longer hydroperiod. Hydroperiod, depth, electrical conductivity, altitude, mean annual temperature and latitude largely influenced the distribution of species in the study area. Co-occurrences of species were overall rare but more common in temporary habitats. Assemblages of diaptomid copepods restricted to certain sites were identified. The importance of temporary habitats is discussed in the light of their species richness, faunal composition and the increasing anthropogenic pressures they face.</p>

Entrepreneurship has been widely considered as the power that drives development and well-being in the regions it affects. As a result, local, regional and national institutions, as well as researches in different disciplines, have focused on finding and researching the factors leading to the installation of business on a certain location. Therefore, it seems well-timed to present a quantitative survey of the literature review of this field. The scope of this article is to present past and present research studies related to the business location factors (BLF) identifying the most important sub-topics, contributors and their geographical distribution, major outlets, main empirical methodologies employed, as well as the most frequently studied countries. The presentation and documentation of the existing literature review could be a valuable tool for policy makers in the regional and national level, as well as for active entrepreneurs and researchers engaged in relevant academic disciples. Policy makers could take advantage of the BLF to attract investments in regions seeking development while active entrepreneurs could realize the important role played by the factors affecting the location of their business in a specific place and researchers could trace and fill in potential research voids on this subject.

As Species

The orchid genera Epipactis Zinn and Ophrys L. are well-known by their complicated taxonomy and extensive debates over species richness within them. These genera are represented in Turkmenistan by two species each. Two of them, namely E. turcomanica K. P. Popov et Neshat. and O. kopetdagensis K. P. Popov et Neshat., were hitherto accepted as species endemic to Turkmenistan. In the present paper, these taxa are synonymized with broadly distributed E. persica (Soó) Hausskn. ex Nannf. and O. oestrifera M. Bieb., respectively. Thus, the genus Epipactis is represented in Turkmenistan by E. persica and E. veratrifolia Boiss. et Hohen., and the genus Ophrys is represented by O. mammosa Desf. and O. oestrifera. There are no species of orchids endemic to Turkmenistan.

A taxonomic study has been made of the species of Rhipicephalus Koch and Boophilus Curtice occurring in Australia. It was concluded that only one species of each genus is present and determination of these as R. sanguineus (Latreille) and B. microplus (Canestrini) respectively, was confirmed. A redescription is given of the male, female, nymph, and larva of each species based on Australian material, the morphological variations observed are noted, and the host range and geographical distribution are discussed.

This article has the objective to overview literature on the topic of the distribution of Malesia mosses which is closely related to tropical forest. This diversity and distribution is an important concern because of the increasing rate of destruction of tropical forests throughout region. Using theoretical literature method, the author summarizes mosses’ wide geographical distribution covering the tropical regions of Asia, the Pacific and Australia. Some types of liverworts do not spread west across the Wallace line. A review of liverworts literature has been conducted but a review specifically on the moss diversity in Melasia region is limited. Thus, this review includes a brief introduction to mosses and then focuses on the following topics; the characteristics of mosses; development of moss plants; classification of moss plants; benefits of moss plants and moss diversity in the Malesia region.

This system, along with other phonologically determined agreement systems, pose problems for our traditional Y-model of grammar, which assumes that phonological features are not present in the syntax (cf.

To do this I argue that pronouns select for an NP complement (cf. Elbourne 2001), where the pronoun enters into an agree relation with its NP complement. When spelled out, the morphologically agreeing heads must be phonologically similar, and this overt agreement licenses ellipsis of the NP. </span></p></div></div></div>
