In this study the results of the captured Coleoptera in pitfall traps in nine olive orchards in the valley of Messara, on Crete Island, were compared. The liquid used for killing and preservation in the pitfall traps, was propylene glycol. The nine olive orchards were distributed in four areas in the valley. In each area there were at least two olive orchards under different agricultural  management system, organic and conventional. The experiments were conducted from October 2004 to April 2005. The number of captured Coleoptera specimens was 4,937. The specimens were identified to the family level. Coleoptera from 25 families were found, but the analysis was focused at eleven of them, the richest in specimens. These were: Anthicidae, Carabidae, Chrysomelidae, Curculionidae, Histeridae, Leiodidae, Scarabaeidae, Silphidae, Silvanidae, Staphylinidae and Tenebrionidae. Staphylinidae were the most abundant in all olive orchards independently of the agricultural management (production system). In the other families instead of differences amongst the different systems of agricultural management, more prominent were the differences amongst areas.

Abstract We describe here the diet of the microhylid frog Chiasmocleis leucosticta based on the stomach contents of 72 individuals (47 males and 25 females) collected in pitfall traps at the Reserva Florestal de Morro Grande, state of São Paulo, southeastern Brazil. We identified 1,981 food items distributed in 13 prey categories of arthropods, mainly ants, mites and collembolans. Formicidae was the most abundant and frequent prey category, including 16 genera from seven subfamilies, and data on ant availability in the habitat suggest that C. leucosticta selects ants actively. The second main prey category was Acari, predominantly represented by mites of the suborder Oribatida. This is the first work identifying mites to the family level in the diet of a Microhylidae. There was no statistical difference between males and females regarding diet composition.

Organizational culture is the driving force behind the transformation of the enterprise. Effective improvement of production systems of industrial enterprises is based on the use of organizational culture resources. The development of the production system is an ongoing process based on such key elements as the management system, management processes and organizational culture. The quintessence of such development is the formation of the cultural shell of the enterprise and the establishment of ideal production, where people are the only active resource, since without them self-development is impossible. The stages of applied measures to improve the production system with various resources that include key development elements: the management system and processes, the formation of a system for collecting, analyzing and using best practices in order to increase the competitiveness of the enterprise, building a self-developing system of continuous improvements, creating an organizational culture that allows maximize the potential of employees and develop their abilities, have been considered in the article. Each stage of the development of PSP must pursue a goal of forming a loyal team.

This article presents the phylogenetic conclusions of an osteological study of species belonging to the subfamilies (Soleinae and Achirinae) of the dextral flatfish family Soleidae (Pieuronectiformes; Soleoidei). A cladistic analysis of the data revealed that the subfamilies, but not the family, are monophyletic. The Soleinae were found to be more closely related to the other soleoid family, the Cynoglossidae, than to the Achirinae. If we accept the principle that only monophyletic groups are to be admitted into Linnean classification, it is suggested that the two subfamilies be raised to the family level. The anatomical data led to the proposal (with caution) that the sister group of the achirid–soleid–cynoglossid lineage is the pleuronectid subfamily Samarinae. Consequently, it is suggested that the suborder Soleoidei be eliminated by incorporating its three families into the Pleuronectoidei which becomes monophyletic. Also, it is proposed that the Pleuronectid subfamilies (Pleuronectinae, Poecilopsettinae, Paralichthodinae, Rhombosoleinae, Samarinae) be raised to the family level. However, since the monophyletic status of these taxa is dubious (except for the Samarinae) any hypothesis including them must await a proper cladistic analysis of their intra- and inter-relationships.

In order to determine the safety of milk produced by smallholder dairy goat farms, a farm-based research study was conducted on commercial dairy goat farms to compare the microbiological quality of milk produced using 3 different types of dairy goat production systems (intensive, semi-intensive and extensive). A survey of dairy goat farms in and around Pretoria carried out by means of a questionnaire revealed that most of the smallholder dairy goat farms surveyed used an extensive type of production system. The method of milking varied with the type of production system, i.e. machine milking; bucket system machine milking and hand-milking, respectively. Udder half milk samples (n=270) were analysed, of which 31.1 % were infected with bacteria. The lowest intra-mammary infection was found amongst goats in the herd under the extensive system (13.3 %), compared with 43.3 % and 36.7 % infection rates under the intensive and semi-intensive production systems, respectively. Staphylococcus intermedius (coagulase positive), Staphylococcus epidermidis and Staphylococcus simulans (both coagulase negative), were the most common cause of intramammary infection with a prevalence of 85.7 % of the infected udder halves. The remaining 14.3 % of the infection was due to Staphylococcus aureus. Bacteriology of bulk milk samples on the other hand, showed that raw milk obtained by the bucket system milking machine had the lowest total bacterial count (16 450 colony forming units (CFU)/mℓ) compared to that by pipeline milking machine (36 300 CFU/mℓ) or handmilking (48 000 CFU/mℓ). No significant relationship was found between the somatic cell counts (SCC) and presence of bacterial infection in goat milk. In comparison with the herds under the other 2 production systems, it was shown that dairy goat farming under the extensive production system, where hand-milking was used, can be adequate for the production of safe raw goat milk.

Abstract Dragastanella transylvanica n. gen. n. sp. is described. Its calcified skeleton contains numerous voids, partly related to the molds of soft parts of the alga, but also related to lack of calcification. Interpretation of these voids, especially their attribution to original structures (e.g., primary lateral versus reproductive organ), has important implications for the taxonomic position of the alga, even at the family level. Examination of key sections that include the boundary between sterile and fertile parts of the alga excludes the occurrence of external reproductive organs. Unusual, paired pores in the outer part of the mineralized skeleton reflect an asymmetry within the whorl, excluding the presence of secondary laterals. The alga is characterized by a cylindrical to club-shaped thallus bearing only phloiophorous primary laterals arranged in whorls and flaring outwards, forming a cortex. Mineralized lenticular reproductive organs containing cysts set in the equatorial plane (Russoella-type gametophores) occur inside primary laterals (cladosporous arrangement of the reproductive organs). These characters support establishment of the new genus Dragastanella. Dragastanella transylvanica n. gen. n. sp. resembles species previously referred to Zittelina (Zittelina hispanica and Zittelina massei) and Triploporella (Triploporella matesina and Triploporella carpatica). Except for Triploporella carpatica, whose mineralized skeleton does not permit confident attribution to either Triploporella or Dragastanella n. gen., the other species must be ascribed to Dragastanella n. gen. Therefore, the following new combinations are proposed: Dragastanella hispanica n. comb., Dragastanella massei n. comb., and Dragastanella matesina n. comb. Despite widely overlapping biometrical measurements, these species can be differentiated by the size and location of their reproductive organs, the pattern of calcification around the primary laterals, and relationships among structural parameters such as the size of laterals, number of laterals per whorl, and distance between whorls.

The intensive development of information technologies and software and hardware of control systems creates conditions for active processes of digitalization of the industry. One of the relevant areas of digitalization in production is the development and implementation of flexible production systems that expand the functionality of production lines and increase the efficiency of the production process. This paper deals with the development of a transport management system of a flexible production system. A solution is proposed that includes a block diagram of the system, hardware and functional logic.

Bamboo corals are distinguished from most other octocorals by an articulated skeleton. The nodes are proteinaceous and sclerite-free while the internodes are composed of non-scleritic calcium carbonate. This articulation of the skeleton was thought to be unique and a strong synapomorphy for the family Isididae. Our phylogeny, based on the amplification of mtMutS and 18S, shows an articulating skeleton with sclerite-free nodes has arisen independently at least five times during the evolutionary history of Octocorallia rather than being a synapomorphy characteristic of a monophyletic bamboo coral clade. The family Isididae is currently composed of four subfamilies (Circinisidinae, Isidinae, Keratoisidinae, and Mopseinae). Not only is the family polyphyletic, but our genetic analyses suggest also the subfamily Isidinae is polyphyletic based on current taxonomic classifications, and Mopseinae is not monophyletic. The type, Isis, is found outside of the well-supported Calcaxonia – Pennatulacea clade where the other members of Isididae cluster. The current classification of the family Isididae does not reflect the evolutionary history of an articulated skeleton. To better reflect the evolutionary history of these taxa we propose that three of the four the subfamilies, the genus Isidoides, and genera within the subfamily Isidinae, be elevated to family level to produce a classification with five families with a bamboo-like skeleton: Chelidonisididae, Isididae, Isidoidae, Keratoisididae, and Mopseidae.

AbstractThis paper is chiefly aimed at reassessing the limits of four bombycoid families, namely the Eupterotidae, Saturniidae, Lemoniidae, and Brahmaeidae. An incompletely resolved cladogram is proposed for the whole 'bombycoid complex' (Mimallonoidea + Lasiocampoidea + Bombycoidea). Within the Bombycoidea, the primary dichotomy is considered to lie between the Eupterotidae + Bombycidae s.lat. + Endromidae + Mirinidae + Saturniidae, and the Carthaeidae + Lemoniidae + Brahmaeidae + Sphingidae. Sharing at least nine synapomorphies, the Lemoniidae and Brahmaeidae are regarded as reliable sister groups, and the Lemoniidae + Brahmaeidae are proposed as a sister group to the Sphingidae. Another newly proposed clade groups together the Endromidae, Mirinidae and Saturniidae. At family level, the Hibrildidae are synonymized with the Eupterotidae (syn. n.), for which the most significant autapomorphy lies in a previously unnoticed particularity of the female hind leg (distitarsus typically provided with a midventral row of spines). Sexual dimorphism in leg structure also leads to a redefinition of the Saturniidae, a family which must include, with subfamily rank (stat. rev.), the 'Oxytenidae' and 'Cercophanidae' of modern authors. A pair of distal, tooth-like structures on the fourth tarsomere of the female fore leg can thus be ascribed to the ground plan of the Saturniidae, along with a few other convincing autapomorphies. On the other hand, the 'Apatelodidae' are only tentatively placed in the 'Bombycidae sensu lato', a group provisionally resurrected insofar as the Apatelodidae sensu auct. prove to be diphyletic. As a matter of fact, the 'apatelodid' subfamily Epiinae is synonymized with the Bombycinae (syn. n.) in consideration of a rather large number of synapomorphies. When more extensively studied, the morphology of the eighth sternum of the male abdomen might lead to a slightly different, more restricted, concept of the Bombycidae (Le. excluding 'true' Apatelodidae). Often regarded as incertae sedis, the African genera Sabalia Walker and Spiramiopsis Hampson are definitely assigned to the Lemoniidae and Brahmaeidae respectively. Autapomorphies of these two families are recorded and discussed, as are those found to characterize the Sphingidae. Three subfamilies are tentatively recognized within the latter (Smerinthinae stat. rev., Sphinginae, Macroglossinae), five within the Eupterotidae (Hibrildinae, Tissanginae, Janinae, Panacelinae, Eupterotinae), and four within the Bombycidae s.lat. (Apatelodinae, Phiditiinae subfam. n., Prismostictinae [= Oberthueriinae, syn. rev.], Bombycinae). Three of these subfamilies are considered in a new sense, viz. the Panacelinae, Apatelodinae, and Bombycinae. Although the phylogeny of the Saturniidae is not fully taken into account in the present study, the composition of three saturniid subfamilies is critically examined (Oxyteninae, Cercophaninae, Ludiinae), and the Oxyteninae are viewed as the most 'primitive' member of the family.

Reef Check is an activity to find out the condition of coral reefs and its surrounding ecosystems be then described and categorized its healthiness. The island of Java is one of the Islands in Indonesia that has lots of beaches, especially for East Java, here they have several areas that has become our research site in Sempu Strait, Sendang Biru, South Malang they are called Teluk Semut, Watu Meja, and Waru-waru. Underwater Visual Census (UVC) was used as a method for this research to identify reef fish in a transect of 100 x 5 x 5m scale in (Length, Width, and Height). Results shows several fishes was used to identify yet the family of  Chaetodontidae with mean abundance 8 in Teluk Semut 1 station, 2.25 in Teluk Semut 2 station, 12.5 in Rumah Ikan station, & 13.5 in Watu Meja station. Watu Meja and Fish Apartment station shows higher mean abundance than other station, this indicates coral reefs ecosystem in this station have a better health & condition compare to the other stations. Results for family family Haemulidae, Snapper and Grouper shows low mean abundance, that indicates overfishing on Sempu Strait, South Malang. In other cases, the purposes of Reef Check is to determine the extents of human activities and its impact against the distribution and the healthiness of coral reefs in the area. For further extent, there has been still indications toward its management system yet fisheries potential in certain areas for this research.

AbstractThe design of sustainable intensive livestock production systems for developing countries must be judged according to their likely impact on economic, ecological, ethological and sociological issues. Economic issues to be satisfied include international competitivity in price of finished products which requires maximizing comparative advantages of available natural resources. Ecological sustainability requires that the production system will result in (i) reduced emissions of the principal greenhouse gases carbon dioxide and methane; (ii) reduced contamination of soil and water resources; (iii) an effective control of soil erosion; and (iv) self sufficiency in on-farm production of energy from renewable resources. Ethological concerns relate to potential effects of production systems on animal welfare and the safety and consumer acceptability (wholesomeness) of foods produced in such systems. Sociological acceptability requires that employment opportunities are increased, especially for women, and that the production system encourages self-reliance with minimum dependence on outside inputs.The basic technology, designed and adapted by Convenio Interinstitucional para la Producción Pecuaria en el Valle del Rio Cauca (CIPAV) and cooperating local farmers in the Cauca Valley of Colombia, uses sugar cane, multipurpose trees and water plants as sources of biomass to provide food for a range of livestock species and fuel for the farm and the family. The chosen crops have a proven high capacity to fix atmospheric carbon dioxide and nitrogen into biomass, which is a permanent carbon reservoir (1 ha planted in sugar cane and trees is a sink for some 80 t carbon dioxide), and also a source of substrate for food and fuel. Sugar cane and trees help prevent erosion, maintain soil fertility, have well developed systems of biological pest control, require minimum synthetic chemical inputs and are easily separated into high and low fibre fractions as required for the different end uses of food for monogastric and ruminant animals and fuel.The preferred animal species are pigs and ducks which adapt readily to the ‘non-conventional’ high-moisture food resources (mainly cane juice, tree leaves and water plants) and have a high meat : methane production ratio. They are complemented by African sheep, dual purpose (Holsteinzebu) cattle and buffaloes, managed as triple purpose animals (draught, milk and meat) and deriving most of their food from the more nutritive parts of the fibrous crop residues. All the livestock are managed in partial or total confinement to minimize environmental damage and to maximize nutrient recycling to the crops.Fuel for the family is derived from the biodigestor which uses as substrate the excreta from the pigs; and from the sugar cane bagasse. Earthworms upgrade the fertilizer value of the excreta from the ruminant animals and produce part of the protein for the ducks.The CIPAV model is flexible as witnessed by the increasing acceptance of many of the elements in the model by both resource-poor and entrepreneurial farmers. The biomass concept, on which the CIPAV model is based, can also be scaled up to the level of agro-industry (the biomass refinery) offering renewable alternatives to present fossil-fuel-based technologies for chemical and energy needs.
