Ludwigia peploides (Kunth) P.H.Raven - Floating primrose-willow - is native to wetlands of North, Central, and South America, and widely distributed across Africa, Australia, and Asia, and in Europe, where it is listed by EU Regulation no. 2016/1141 as an Invasive Alien Species (IAS) of Union concern. A photograph of the species from Romania taken in the Sai River Valley (Teleorman County) was published on the Facebook online platform in 2018. This first record, however, lacked further details on the observed specimen or any accompanying herbarium material that would ascertain its correct taxonomic assignation. By carrying out our own field surveys between October and November 2020 we hereby confirm the presence of the species Ludwigia peploides as a new addition to the Romanian alien flora. We identified many specimens occurring along the Sai River Valley, between Olteanca and Turnu Magurele localities. We further present preliminary data regarding the distribution, affected habitats, and population extent of Ludwigia peploides in the investigated area. Although several hypotheses can be proposed on the origin of this species in Romania, our current data cannot strongly support any of them. Plant specimens were deposited in the Herbarium collection of the D. Brandza Botanic Garden of the University of Bucharest (BUC).

This paper reports seven species of opisthobranchs from the intertidal zone of the south Saurashtra coastline off the Arabian Sea, Kathiawar Peninsula, west coast of India. Field surveys were undertaken along the intertidal zones of south Saurashtra coast during 2012–2014. In this study, seven species belonging to six families were recorded, of whichHaminoea ovalis, Flabellina bicolor, Phidiana militaris, Baeolidia palythoaeandSakuraeolis gujaraticaare new records from this coastline.

IDENTIFICATION AND CHARACTERISATION OF LANDSCAPE IN PORTUGAL –This paper presents the concepts and methodology used in the study «Identification and characterisation of landscape in continental Portugal» undertaken by theDepartment of Landscape and Biophysical Planning of the University of Evora for the General Directorate for Spatial Planning and Urban Development (DGOT-DU) at the Ministry of the Environment and Spatial Planning, between 1999 and 2001. On the one hand, the methodological approach developed is based on the methodologies used recently for the same purpose in different European countries and on the way landscape has been considered in various European documents in the last years. On the other hand, it is also based on the team’s concern to approach the landscape as an holistic entity, and to examine its various components: ecological, cultural, socio-economic and sensorial. The set aim has been to define landscape units and to characterize these units in relation to the present landscape and the recorded trends, related problems and possibilities. Thus, the cartography relative to selected variables has been combined and related to satellite images and field surveys. The results of cross-referencing all this information has than been combined with expert examination of landscape coherence and character within each unit. The assessment was completed after careful bibliographic research and consultation with regional experts. The result is a flexible approach that combines objective analysis with a more subjective assessment, which the team considered fundamental for a true understanding of landscape.

Abstract. The representation of the areas in which some of the most significant events of the First World War took place has produced a wide range of materials, such as cartography, aerial and terrestrial photos, textual descriptions and field surveys. In addition, war events were also represented through three-dimensional models. Topographic maps and models constitute composite figurations, which are rich in informative data useful for the preservation of the memory of places and for increasing the knowledge of cultural heritage. Hence, these sources need to be studied, described, interpreted and used for future enhancement. The focus of this paper are archival materials from the collections kept at the Italian War History Museum of Rovereto (Museo Storico Italiano della Guerra), in the Trentino-Alto Adige region. Firstly, we will investigate the cartographic fond in order to assess the composition and origin of its materials. Secondly, we will present the Museum’s collection of Early-Twentieth Century models. Such precious heritage is not yet part of an exhibition, and is kept in the Museum’s warehouses. The paper constitutes the occasion to present the initial results of a still ongoing project by the Geo-Cartographic Centre for Study and Documentation (GeCo) of the University of Trento on the study and analysis of two archival complexes preserved in the abovementioned Museum. In particular, the paper focuses on the heuristic value of such representational devices, which enable an analysis of the different methods and languages through which space is planned and designed, emphasizing the complementarity between different types of visualization.

This article is concerned with the consideration of “Caddo connections” as expressed in the character of the ceramic assemblages from three sites in the Leon River valley in Central Texas that have been considered to have Caddo pottery and were occupied by Prairie Caddo peoples; these ceramic assemblages are in the collections of the Texas Archeological Research Laboratory at The University of Texas at Austin (TARL). Of particular importance are the stylistic (i.e., decorative methods and decorative elements) and technological (i.e., choice of temper inclusions) attributes of the sherds from the sites that are from plain ware, utility ware, and fine ware vessels.

ABSTRACT Mosquito surveillance was conducted in Nachusa Grasslands Preserve located in north central Illinois in May through October during 2018 and 2019. In the Lee and Ogle counties, Illinois, boundaries of the preserve, 3 Uranotaenia sapphirina and 3 Aedes japonicus were collected and documented over the 2 field seasons in wetland and stream habitats. While Ur. sapphirina has been reported in nearby states, this is the first record in Lee County and on the preserve. Aedes japonicus has previously been recorded in Lee County; however, this is the first observance of this species within Ogle County and on the preserve.

Replacing failed bulbs of streetlights in a location can be very tasking and expensive if the optimal time for replacement is not determined. In this paper, a model has been developed that helps to establish the optimal time for the replacement of streetlight bulbs. Burnt-out bulbs are replaced individually when they fail, and group replacement is carried out on all bulbs after a specified time. The costs for both individual replacement and group replacement are determined. The developed model was applied to locally sourced data from a field survey of a streetlight installation at the University of Ilorin, Ilorin, North-central Nigeria. The model gave the optimum replacement time of burnt-out bulbs as the eighteenth week when applied to the data used in this work. The optimum replacement time will be dependent on the dataset used. This makes the developed model useful in establishing the optimal replacement time of any stochastically failing items that are in large quantities. The model will help to reduce maintenance costs for facility managers.

Abstract Amaranthus spinosus L. (Amaranthaceae s.l.), a species native to the Neotropics, has been found in four localities (Bizerta, Bir Bouregba, Hammamet, and Nabeul) of N. Tunisia. Our discovery represents the first record at national level, and the second one for N. Africa. Morphological characters and ecological data are given. Nomenclatural notes are provided for the name A. diacanthus, which was regarded by some authors as heterotypic synonym of A. spinosus. A neotype is designated in the present paper based on a specimen preserved at LSU.
