Correct assessment of its impact on coral reef ecosystems requires an understanding to its biology and ecology. This present study was conducted to determine the abundance, size structure and preyed corals of A. planci in Lungui Island, Dimataling, Southern Philippines. Four replicates of 50 × 4 m belt transects were laid in each of three sampling stations. A total of 112 A. planci individuals were recorded, whose body sizes varied significantly between the three stations (H = 3.401; p = 0.0180 at α = 0.05) ranging from 120 to 270 mm. All detected A. planci individuals were observed foraging on corals. Five preyed coral genera were identified through morphology-based identification, where Pocillopora was the most preyed coral genus, foraged by 28.57% of total A. planci individuals. Although the number of A. planci individuals in Lungui Island has not reached the outbreak threshold level, its presence in the area should not be overlooked. In fact, this raises a need for continuous monitoring of its population level in these local reef areas of the coastal waters of Dimataling, Southern Philippines.","PeriodicalId":53270,"journal":{"name":"Environmental and Experimental Biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45642110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some parameters were assessed at the sampling sites and the others in the laboratory. Microbial diversity was explored by using morphological, biochemical, MALDI-TOF-mass spectrometry and molecular approaches. The α-diversity of Gauri Kund was 24 with 14 strains of bacteria, five strains of actinomycetes and five strains of fungi. The α-diversity of Gangnani Kund was 22 with 10 strains of bacteria, five strains of actinomycetes and seven strains of fungi. The α-diversity of Tapovan Kund was 18 with eight strains of bacteria, four strains of actinomycetes and six strains of fungi. The current study can be a good reference for further similar studies. The available data will also help to understand the reasons behind the curative properties of these hot water springs.

In Latvia, this species was first recorded in 1989 in Liepāja. Observations in recent years in Liepāja have shown that snails from their initial introduction sites on the railway have also spread to the sand dune habitats within the city limits. Given that there are no snails in dune habitats that are biologically equivalent to X. obvia, this species is considered to be potentially invasive. As the distribution trends of this species in Liepāja indicate a possible threat to dry habitats in natural areas, detailed study of the species was conducted for the population of this species located in Dobele. Monitoring was performed from May 26 to August 5, 2019, carrying out 11 surveys with one week interval using the capture and re-capture method. The maximum recorded distance travelled by of one snail was 29.7 m; the calculated minimum estimated population density was 170 individuals and the maximum was 2004 individuals.","PeriodicalId":53270,"journal":{"name":"Environmental and Experimental Biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47502532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The alga identified in the present study was earlier reported from the same state but 350 km (north) towards Belagavi, Karnataka. Morphological data of the current specimen showed more than 95% similarity with the species K. zeylanica in cluster analysis. Morphological characters like a distinct centrally inserted carposporophyte and contorted carpogonial branches allowed to categorize the alga under the genus Kumnaoa.

It is important to specify the cause of death, in order to recommend the correct treatment option. Dead bees have specific body positions (e.g. extended proboscis, separated wings, extended stingers), which can be described to help in the identification of the death cause. There are no previous evidence on links between body positions of dead bees and death cause. In this study, honey bee workers were exposed to various lethal conditions (low temperature, high temperature, starvation, suffocation, pesticide exposure, and food contamination). Then, the body positions of dead bees exposed to each lethal condition were described in detail. Differences in positions of antenna, proboscis, wings, legs, abdomens, and stingers were detected between dead bees exposed to the tested lethal conditions. These differences are discussed and further studies were then recommended. This study presents the potential use of baseline observations on relationships between the body position of dead bees to stress factors as a mean to predict the cause of death of honey bee workers.","PeriodicalId":53270,"journal":{"name":"Environmental and Experimental Biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44683847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both EOs had inhibitory effect against mycelial growth of all studied isolates. However, the antifungal effect of EO isolated from P. mauritanica was stronger than for that from M. debilis, with 100% inhibition against Alternaria tenuissema (isolates A18 and A57), Alternaria alternata (isolate AT4), Alternaria solani (A37) and Alternaria tomatophila (AT01), when used at 1.1 μL mL–1 concentration. EO from M. debilis had 100% inhibition against isolates A42 and A57 of A. solani and A. tenuissema when used at 1.1 μL mL–1 concentration.
