<abstract xmlns="http://www.w3.org/1999/xhtml">The Wieprz-Krzna Canal, built in 1961, is one of the longest in Poland (142 km). Although the drainage construction was intended to revitalize the region of wetlands and peat-bogs of the West Polesie, it caused large hydrological changes. Research on catchments of three natural lakes and three retention reservoirs involved cartographic analysis using photointerpretation, as well as the Braun-Blanquet method. In the studied area, between 1939 and 2016 the length of rivers and ditches increased more than three times. Macrophytes covered about 20-27% of the natural lakes water surface, whereas in retention reservoirs the coverage was 12-15.5%. Also a greater diversity of macrophytes occurred in natural lakes. In retention reservoirs it was restricted to only emerged macrophytes.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"><italic>Acanthus ilicifolius</italic> L. (Acanthaceae) is an evergreen non-viviparous mangrove associate. It is hermaphroditic, strongly protandrous, self-compatible, facultative xenogamous, temporally dioecious and melittophilous. The floral mechanism is highly specialized and adapted for pollination by large-bodied bees. The natural fruit set is below 30%. The fruits mature within a month and usually contain four seeds. The fruit is a capsule and splits explosively in the dorsi-ventral plane ejecting the seeds away. This makes it anemochorous. The gregarious occurrence of the plant at the study site is attributed to propagation by seed and vegetative modes.</abstract>

The general morphology, the mouth parts (antenna, mandible, maxillule, maxilla, and maxilliped), the outgrowth developed between the post-antennary process and the antenna, the setal and spinal formula from first leg to fourth leg in this study are compatible according to the specific literature.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Fish from three major rivers, namely the Kelantan River (KR) and the Galas River (GR) in Kelantan, and the Perak River (PR) in Perak, Malaysia, were caught using gill nets with different mesh sizes, cast nets, and the electroshock method. There were 14 fishes representing five families and five fish species were collected from the Kelantan systems in February 2015. While the Galas system holds more fish, 48 individual fishes comprising of four families and 10 fish species were found there. A total of 213 fish specimens representing 10 families and 22 species were captured in PR in May 2015. For diversity index, PR had the highest value due to the catchment area and the environmental condition: Shannon-Weiner index (H’) (2.54), Species Evenness (J’) (0.73) and Simpson’s Dominance (D’) (8.93), compared to GR (H’) (2.09) (J’) (0.603) (D’) (6.52) and KR (H’) (1.62) (J’) (0.47) (D’) (5.62).</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">In autumn 2015 the fish fauna of river watersheds from six sites of community interest (SCI) Natura 2000 were investigated as follows: river Mureș (two SCIs) and Someș River in four SCIs from Someșul Mic, Someșul Mare and Someș. The researches were focused on the fish species of community interest (Annex II of Habitats Directive), its position in the ichthyocoenose (fish species richness, abundance and ecological parameters) and anthropogenic pressure. In investigated SCIs rivers researchers found 27 fish species including 11 species of community interest. IBI index shows moderate to good, or excellent levels of the evaluation integrity degree in fish fauna ecosystems.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">This research indicated that one cave fish species of <italic>Oreonectes jiarongensis</italic> can recover the transparent to black under the light condition, this species belongs to the <italic>Oreonectes</italic>, Nemacheilinae, and distributes in Libo County, Guizhou Province, China. The changing process time was 14 days. This is the first time that suggests the cave vertebrates which lived in the dark environment not longer time could change the body color in the light environment, and has a new adaptive strategy for the darkness condition. The result may indicate that this species entrance the underground river not so long time, and the genes not mutation, which control the melanin express, it still has the physiological regulation mechanism under the light condition.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Herbicides are used to control weeds and are usually targeted to sites that are specific to plants. Butachlor is an herbicide of the acetanilide class, which is widely used in agricultural fields. At the present study, lethal concentration (LC50) of butachlor was calculated for <italic>Rutilus rutilus caspicus</italic> and <italic>Sander lucioperca</italic> with a mean weight of 4 ± 1 g (mean ± SD). Our results indicated that LC50 96 h butachlor for <italic>R. rutilus caspicus</italic> and <italic>S. lucioperca</italic> were 0.342 and 0.760 ppm respectively. These findings suggest that butachlor is moderately toxic and moderately irritating for these two species. Clinical symptoms included irregular protrusion of the eyes and irregular swimming.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Of the 37 species of the European Union concern eight are already present and two present a future potential risk for Romania. This paper brings updated information regarding these species in Romania. The presence of eight invasive alien species of concern to the European Union have already been recorded in Romania: two plant species <italic>Cabomba caroliniana</italic> and <italic>Heracleum sosnowskyi</italic>, two crustaceans <italic>Orconectes limosus</italic> and <italic>Eriocheir sinensis</italic>, two fish species <italic>Pseudorasbora parva</italic> and <italic>Perccottus glenii</italic>, one reptile <italic>Trachemys scripta</italic> and one mammal <italic>Myocastor coypus</italic>. Other two species of Union concern (<italic>Lithobates catesbeianus</italic> and <italic>Procyon lotor</italic>) may soon become invaders in Romania. We emphasize the urgent need to assess their current distribution and impact or potential to establish and possible impact at national level.</abstract>
