Term Rain

The distribution and abundance of intertidal organisms can be affected by short-term events, such as rain. We compared the effects of rain on intertidal mobile invertebrates in four common microhabitats with differing amounts of shelter (namely beds of oysters, coralline turf, bare patches and crevices) on sea walls in Sydney Harbour. There was an effect of rain on some, but not all taxa, although this was not consistent between locations or times. Effects of rain were observed for some species of gastropods and crustaceans, but not for polychaetes. Manipulative experiments using artificial rain indicated that rain, without the presence of run-off and independent of potential temporal confounding from differences in weather conditions, has a negative effect on abundances of amphipods in coralline turf. Pulse responses by mobile organisms to short-term rain events should be considered when designing experiments looking at temporal variability and processes responsible for observed patterns of distribution of marine organisms.

AbstractExercise can influence gut microbial community structure and diversity; however, the temporal dynamics of this association have rarely been explored. Here we characterized fecal microbiota in response to short term changes in training volume. Fecal samples, body composition, and training logs were collected from Division I NCAA collegiate swimmers during peak training through their in-season taper in 2016 (n=9) and 2017 (n=7), capturing a systematic reduction in training volume near the conclusion of their athletic season. Fecal microbiota were characterized using 16S rRNA V4 amplicon sequencing and multivariate statistical analysis, Spearman rank correlations, and random forest models. Peak training volume, measured as swimming distance, decreased significantly during the study period from 32.6±4.8 km/wk to 11.3±8.1 km/wk (ANOVA, p<0.05); however, body composition showed no significant changes. Coinciding with the decrease in training volume, the microbial community structure showed a significant decrease in overall microbial diversity, a decrease in microbial community structural similarity, and a decrease in the proportion of the bacterial genera Faecalibacterium and Coprococcus. Together these data demonstrate a significant association between short-term changes in training volume and microbial composition and structure in the gut; future research will establish whether these changes are associated with energy balance or nutrient intake.

Hydrometeorological Conditions

&lt;p&gt;To determine the specificity of functioning the Southern Baltic coasts, it is necessary to identify the hydrometeorological conditions that have the greatest effect on the dynamics of geomorphological processes in detail. For the offshore coastal zone, it is important to determine temporal variability (including trend, cyclicality and seasonality) and spatial diversity (i.e. for cliff and dune coasts) of occurrence of main hydrometeorological and geomorphological processes and events. Among hydrometeorological and geomorphological factors - which are decisive for violent, intense and sometimes irreversible changes in the natural environment - extreme events play an important and sometimes dominant role (Tylkowski, Hojan 2018).&lt;/p&gt;&lt;p&gt;Geomorphological changes of the cliff coast depend mainly on the dynamics of marine and slope erosion. The high sea level that occurs during storm swells and intense precipitation lead to the transformation of the cliff coast, which is seen in the retraction of the cliff crown, among others (Kostrzewski et al. 2015).&lt;/p&gt;&lt;p&gt;The purpose of the work was to determine the temporal variability of hydrometeorological conditions, which have the greatest effect on the dynamics of the erosion of the cliff shores of the Wolin island. Hydrometeorological conditions from 1985 &amp;#8211; 2019 period were compared to the annual measurements of the cliff crown retraction, which were carried out on 5 test sections in the coastal zone of the Pomeranian Bay on the island of Wolin. The work indicates the occurrence of above-average and extreme hydrometeorological events that potentially favoured the occurrence of erosive processes, e.g. mass movements, slopewash and aeolian erosion.&lt;/p&gt;&lt;p&gt;Using ARIMA modelling, time decomposition of hydrometeorological conditions was made and their short-term forecasts were formulated. The study determined non-seasonal and seasonal parameters that determine the occurrence of current and future meteorological and marine conditions. What is more, spatial differences in the scope of identification of the features of the analysed time series, estimation of parameters of selected models and the formulated forecast are indicated (Tylkowski, Hojan 2019).&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;&lt;p&gt;References&lt;/p&gt;&lt;p&gt;Tylkowski J., Hojan M., 2018.
