Abstract

The article examines issues of local water resources using Bela Krajina as an example - a rural, karst landscape in south-eastern Slovenia. In the field, we made an inventory of 261 different water resources, analysing their past and current use along with their role in the life of the local population and assessing their hydrogeological sensitivity and hydroecological threat they face. With the introduction of distributed water systems, water resources lost their traditional importance in terms of water supply, with local population’s reliance on and knowledge about them fading. Nevertheless, certain local communities have recently recognized their natural and cultural value, as well as their importance to ecosystems, which is reflected in initiatives for the preservation, protection and restoration of individual water resources. Most of Bela Krajina’s water resources are very sensitive to pollution due to the karst surface, however the actual hydroecological threat they face from human activities in their catchments is relatively low.

Abstract

Soil fertility properties, irrigation water quality, mineral nutrition, and some vegetables mineral composition were studied in the frame of a project regarding yield quality monitoring in certified organic vegetable farms, in two farms placed on the outskirts of Bucharest Municipality which provide products for the town’s organic market. Chemical analysis of the soil samples collected from the two farms reflects a good fertility, close to the natural one of this region soils, with well-balanced organic matter, total nitrogen, accessible phosphorus and potassium contents. The nitrates contents concord with the plants nutrition demands and don’t present the risk to accumulate in vegetables or to leach into the groundwater. Slightly increased microelements, both total and soluble forms, occur. Soil microbiological properties are favorable for vegetable plants growth. A good biodiversity is noticed. There are differences between soil properties in open field and greenhouses, induced both by the type and degree of mechanical works and materials applied for fertilization and plant protection. Good conditions are generally created for plants mineral nutrition. Mineral nutrition status of the vegetables grown in organic conditions, assessed by the leaves mineral composition, doesn’t differ from the one of the vegetables grown in conventional conditions. The vegetables (fresh material) harvested from the two studied farms have good, even high, concentrations of mineral elements important for the yield nutritional quality. The excessive microelements quantities noticed in soil don’t transfer in the yield, so the latter quality and nutritional properties are not altered.

Soybean versus other food grain legumes: A critical appraisal of the United Nations International Year of Pulses 2016

, common bean, and soybean ( Kumar et al., 2011 ). Soybeans are also treated as pulses in agronomic research literature: Miller et al. (2002) reviewed pulse crops such as soybean [ sic! ], dry pea, lentil, dry bean, and chickpea as compared to spring wheat with respect to their adaptation to the Canadian and United States northern Great Plains region; with the exception of maturity requirements, which are higher for soybean than for the other grain legumes, soybean did not differ from other species in input parameters such as rainfall or average maximum temperature

Bledi srakoper Lanius isabellinus gnezdi v širokem pasu od Irana prek osrednje Azije in severne Kitajske do Mongolije. Prezimuje v osrednji in vzhodni Afriki, Pakistanu in Indiji. V Evropi se redno pojavlja, predvsem med koncem aprila in začetkom junija ter med začetkom septembra in koncem novembra. Pojavljata se (pod)vrsti isabellinus in phoenicuroides. V srednji in jugovzhodni Evropi so znana opazovanja iz Avstrije (3), Romunije (1) in Grčije (8). Avtorji prispevka predstavljajo prvi opazovanji za Bolgarijo, in sicer je bil 24. 5. 2010 na gori Slavjanka opazovan drugoletni samec nedoločene (pod)vrste, 28. 9. 2014 na jezeru Durankulak pa odrasel samec (pod)vrste isabellinus. Opazovanji je kot prvo in drugo za državo potrdila bolgarska komisija za redkosti BUNARCO.

Objavljanje in osnovna analiza obročkovalskih podatkov sta sicer pogosti temi člankov, redko pa so objavljeni podatki iz posameznega mesta, kot je denimo Sombor v premalo raziskani regiji Srbije. Predstavljamo podatke o obročkanju in ponovnem ulovu plavčkov Cyanistes caeruleus in velikih sinic Parus major za obdobje 32 let. Dodatno smo preverili vpliv povprečne najvišje temperature jeseni (september-december) in pozimi (januar-marec) na njihovo številčnost ter pojavljanje v dveh osnovnih habitatnih tipih (parki in vrtovi) v mestu Sombor. Skupno smo obročkali 1675 plavčkov (ponovno ujeti osebki N = 407) in 8062 velikih sinic (ponovno ujeti osebki N = 1517). Pri obeh vrstah so prevladovali mladi osebki (koda EURING 3 oz. 5). Najstarejše obročkane ptice obeh vrst so bile mlajše kot zabeleženo v drugih evropskih raziskavah. Številčnost obeh vrst ni bila povezana s povprečno najvišjo jesensko oziroma zimsko temperaturo. Število obročkanih ptic v parkih in vrtovih se ni pomembno razlikovalo. Glede na ugotovitve predhodnih raziskav sklepamo, da je njihova številčnost v posameznem habitatnem tipu odvisna od razpoložljivost hrane in vremenskih razmer, ne pa drugih okoljskih dejavnikov.

Abstract

In the present study, we investigated plant communities with Yellow Oat Grass (Trisetum flavescens (L.) Pb.) in the submontane and montane regions of Slovenia. In 2005-2007 ninety-one relevés were collected by using the standard procedure of the Braun-Blanquet approach. Relevés were analysed with multivariate analysis and classified within two associations: Astrantio-Trisetetum (Polygono-Trisetion) and the Pastinaco-Arrhenatheretum (Arrhenatherion). Management practices, soil conditions and altitude were found to be significant factors for a further subdivision of both associations. Within the Astrantio-Trisetetum association three subassociations could be distinguished: -typicum, -buphthalmetosum and -trollietosum, and subassociations -typicum, -medicagetosum lupulinae, as well as -lolietosum subass. nova in the Pastinaco-Arrhenatheretum. The floristic composition and ecological characteristics of these plant communities are described and their implications for grassland conservation in Slovenia are discussed.

Abstract

The evolutionary history of Ophioglossaceae is enigmatic mainly because fossils of the family trace back only from the earliest Tertiary. Phylogenetic analyses indicate that Helminthostachys is sister to the broadly defined Botrychium. Generally the sporophore of Botrychium is a pinnately compound, whereas it is simple in Helminthostachys. Here examples of different Helminthoistachys are represented which show double or triple spikes with some variations. Plants showing variations in their spike morphology are also grown normally. Variations of Helminthostachys spike morphology indicate a tendency to form a compound sporophore structure and in that way have a strong relationship with Botrychium.
