Globally, there is growing concern regarding the effects of the increasing anthropogenic pressures in marine communities. Artificial structures such as marinas and aquaculture facilities serve as invasion hotspots; hence, monitoring fouling communities on these structures can be valuable for detecting new invasions. In the current study, 24 settlement PVC plates were deployed for three months to compare the recruitment ability of these two artificial environments along the south coast of the offshore island of Madeira (NE Atlantic). The results showed higher variations in the species richness between regions (SW vs. SE) than between artificial habitats (sea-cages vs. marinas), although the community composition differed. Cnidaria and Bryozoa were the most representative groups in the aquaculture systems, while Bryozoa and Chordata were in the marinas. A sum of 18 NIS was recorded for the study, accounting for between 21.88% and 54.84% of the total number of species in the aquaculture facilities and marinas, respectively. The higher NIS percentage from the marinas was even more explicit in the SE coast, where Cradoscrupocellaria bertholletii, Parasmittina alba, and Botrylloides niger distinctly dominated fouling populations. The results suggest that at least some particular NIS previously reported in the studied marinas successfully colonized sea-cages. Future assessments need to address the potential role of aquaculture facilities as drivers for the secondary spread of NIS. Additionally, two new records are considered for Madeira: Eudendrium capillare and Ericthonius punctatus.

This study was conducted in the sacred grove of Lumbini to elucidate its potential role in biodiversity conservation in Nepal. Lumbini Development Trust enumerated tree species of the grove. We have assessed taxonomic validity by identifying the species. A total of 65 tree species, 39 are indigenous to Nepal, were found in the grove. Most of the species were tropical/subtropical elements that are found to be distributed in Nepal from 100 to 2400m asl. Among total indigenous trees, 64 % trees have their distribution in the whole Nepal, whereas 19 %, 14 % and 3 % are limited to central, eastern, and both central and western part of Nepal respectively. The indigenous species found in the grove accounts for 11 % of total tree diversity of Nepal. Of these tree species, five are of threatened, vulnerable and endangered categories. The forest formation of the grove conforms to Dalbergia sisoo-Acacia catechu type's forest of Nepal. However, majority of the trees in the grove were produced by plantation so it has contributed to ex-situ conservation of trees, and hence this reflects the importance of sacred grove. Key words: conservation, distribution, indigenous trees, Lumbini, Sacred grove, sacred plants, tree species.   doi: 10.3126/banko.v18i1.2163 Banko Janakari, Vol. 18, No. 1, 25-31

Previous research has shown that subjective underemployment is inversely associated to job satisfaction, psychological well-being and health. To our knowledge, the current is the first study that explores subjective underemployment in undergraduates in Colombia. One hundred and forty-two workers participated in a correlational, and comparative study. Results replicated previous findings: as subjective underemployment perception increased, job satisfaction and general life satisfaction decreased. Significant differences were found in the indicators of job satisfaction and general life satisfaction among those who perceive underemployment and those who do not. Finally, the potential role of subjective underemployment on employees’ health is discussed.

Abstract The Popeye domain-containing gene family encodes a novel class of cAMP effector proteins in striated muscle tissue. In this short review, we first introduce the protein family and discuss their structure and function with an emphasis on their role in cyclic AMP signalling. Another focus of this review is the recently discovered role of POPDC genes as striated muscle disease genes, which have been associated with cardiac arrhythmia and muscular dystrophy. The pathological phenotypes observed in patients will be compared with phenotypes present in null and knockin mutations in zebrafish and mouse. A number of protein–protein interaction partners have been discovered and the potential role of POPDC proteins to control the subcellular localization and function of these interacting proteins will be discussed. Finally, we outline several areas, where research is urgently needed.

In serial memory for spatial information, some studies showed that recall performance suffers when the distance between successive locations increases relatively to the size of the display in which they are presented (the path length effect; e.g., Parmentier et al., 2005) but not when distance is increased by enlarging the size of the display (e.g., Smyth & Scholey, 1994). In the present study, we examined the effect of varying the absolute and relative distance between to-be-remembered items on memory for spatial information. We manipulated path length using small (15″) and large (64″) screens within the same design. In two experiments, we showed that distance was disruptive mainly when it is varied relatively to a fixed reference frame, though increasing the size of the display also had a small deleterious effect on recall. The insertion of a retention interval did not influence these effects, suggesting that rehearsal plays a minor role in mediating the effects of distance on serial spatial memory. We discuss the potential role of perceptual organization in light of the pattern of results.
