A simple technique of random leaf collecting for biometric studies in a tree stand

The method reflects proportions in the number of leaves of different sizes and shapes, which appear in a tree stand. The study was carried out during autumn leaf fall, in about a hundred years old tree stand, dominated by beech. Leaves were collected three times, altogether with assessment of foliage density. For all gathered leaves, the width and length were measured and the data were statistically analyzed. Differences among all three samples were significant, which indicates different size of falling leaves in the following periods. Thus, only the research carried on at the end of leaves falling allows collecting a sample which represents proportions among leaves of different sizes in the tree stand.

Abstract

New faunistic data on the distribution of 50 species of the family Agromyzidae from the Afrotropical Region are given. Chromatomyia syngenesiae Hardy, 1849 and Phytomyza ranunculi (Schrank, 1803) are firstly recorded for the Afrotropics and 47 species are firstly recorded for the following countries: Angola, Cameroon, Cape Verde Islands, Central African Republic, Ethiopia, Kenya, Madagascar, Malawi, Namibia, Nigeria, Sierra Leone, Somalia, Tanzania, Uganda, Zambia, Zimbabwe. For each country the number of known species are put together in a table. An updated Afrotropical checklist is added. The most peculiar genitalia of the redetected Ophiomyia dhofarensis are discussed in connection with other species, among them: Ophiomyia yunnanensis comb. nov. [= Ophiomyia dumosa syn. nov.]. Ophiomyia nigrimaculata comb. nov. is treated taxomically, too. The type-species of the Pseudonapomyza acanthacearum-group is re-defined. Ranunculus was firstly confirmed as host plant genus of Phytomyza subeximia which develops between its seeds, a rare substrate in the genus. Napomyza strana stat. rev. was redetected in an altitude of 3353 m a.s.l. An eclector collecting method is described which lets estimate the natural proportional abundance of Agromyzidae compared with all other Diptera in the groundlevel vegetation of a country.

Abstract

The combat potential of future warships will be directly related to the use of modern electronic devices being parts of advanced systems, such as, for instance, radar systems, fire aiming systems, fire detection systems, electric drive systems, and even electronic and radio-electronic weaponry, railguns and lasers, installed on these warships. The capacity and functionality of these devices is continually increasing, at decreasing mass and dimensions, which results in higher power consumption. Heat collection becomes a growing problem in operation of these devices.

The paper presents a concept of the use of the CPL (Capillary Pumped Loop) cycle for passive heat collection from precise electronic devices used on warships. It also includes the description of the experimental rig and discussion of the results of laboratory tests performed on this rig and confirmed using the mathematical model developed by the authors.

Abstract

This research aims to investigate the Simuliidae fauna of Yeşilırmak River basin and determine the species composition of the collecting sites. The study was carried out in July 2008 and June 2009. One genus and eleven species (Metacnephia sp., Metacnephia subalpina, Simulium (Eusimulium) angustipes, Simulium (Nevermannia) costatum, Simulium (Simulium) argenteostriatum, Simulium (Simulium) bezzii, Simulium (Simulium) ornatum, Simulium (Simulium) trifasciatum, Simulium (Simulium) variegatum, Simulium (Wilhelmia) balcanicum, Simulium (Wilhelmia) lineatum and Simulium (Wilhelmia) pseudequinum) were recorded from 16 collecting sites. The distribution and abundance of Simuliidae species reflect the changes in water quality of Yeşilırmak River, due to agricultural activities and urban areas.

Abstract

The first ever liverwort and hornwort checklist is provided for Paraguay. Despite the high level of biological diversity in Paraguay, there remain very few intensive collecting efforts for liverworts and hornworts in the region since the late 1800’s. We report 2 hornwort taxa and 71 liverwort taxa. The list is based on almost 100 literature references, including monographs, regional studies, and molecular investigations. Given the dramatic loss of habitats in Paraguay coupled with high species diversity in other organisms, further collecting of liverworts and hornworts is critical. There is also the potential to use historical records with contemporary collections to investigate the impact of habitat loss in the area.

Abstract

The nutritional status of plant canopies in terms of nutrients (C, N, P, K, Ca, Mg, Mn, Fe, Cu, Zn) exerts a strong influence on the carbon cycle and energy balance of terrestrial ecosystems. Therefore, in order to account for the spatial and temporal variations in nutritional status of the plant species composing the canopy, we detail the methodology applied to achieve consistent time-series of leaf mass to area ratio and nutrient content of the foliage within the footprint of the Integrated Carbon Observation System Ecosystem stations. The guidelines and defi-nitions apply to most terrestrial ecosystems.

Abstract

In this study, we aimed to determine the reference sites and their reference Ephemeroptera communities according to the Water Framework Directive methods in the Eastern Part of the Black Sea Region of Turkey between 2008-2011. From the area, twentyfour collecting sites were chosen. There were thirty Ephemeroptera species identified, belonging to seven families and eleven genres. Cluster analysis based on Bray-Curtis similarities was applied. Reference habitat conditions of the studied sites and their reference Ephemeroptera communities were determined by combining both ecological and statistical results. As a result, sixteen sites had reference habitat conditions and their reference Ephemeroptera species were identified.

Abstract

Although the geographical location and botanical history of Turkey make the country a perfect place for a potentially rich diversity of eriophyoid mites, little is known about the Turkish eriophyoid fauna. The current paper is a brief review of the existing records of eriophyoid mites found so far in Turkey, with additional information on 6 grass-associated eriophyoid species recorded recently. The 134 eriophyoid species collected in Turkey come from only ca. 1.2% of all Turkish plant species. The role of collecting ecological and molecular data and studying economically significant eriophyoid mites species in this area is particularly stressed.
