Seasonal dynamics of macroalgal communities was analyzed monthly by samplings in three stream segments of the Pedras River Basin, mid-south region of Paraná State, southern Brazil, from April 2004 to March 2005. The seasonal fluctuations in macroalgal species richness and abundance were correlated with selected environmental variables. In general, the seasonal distribution patterns of these communities were distinct from those reported from other tropical and temperate regions, with higher macroalgal richness and abundance observed from late spring to late fall. Multiple linear regression analysis revealed that the stream variable most closely related with the temporal distribution pattern observed was temperature, which had a very similar seasonal pattern to the biological parameters. On the other hand, the floristic composition was quite diverse in the streams sampled. Among the 25 taxa identified, only two were common to the three streams whereas 15 were restricted to a single sampling site. These data indicate that, although temperature seems to be an effective relationship with global temporal pattern, particular characteristics of each stream can strongly influence the seasonal tendencies in local scale. The results of Detrended Correspondence Analysis (DCA) and Cluster Analysis corroborated this observation.

Hip replacement is the most common surgical procedure among Medicare patients in the US and worldwide. The hospital length of stay (LOS) for hip replacement admissions is therefore important to be controlled, contributing to savings for hospitals. This study combined medical claims and hospital structure and service data to examine LOS fluctuations and trends, and admission distribution patterns, during weekdays, for hip replacement cases. The study furthermore examined associations of these patterns with the LOS performance. Most hospitals were found to admit hip replacement cases at the start of the week (Monday through Wednesday). There is an upward LOS trend as we approach late weekday admissions. Multiple linear regression analysis showed that LOS weekday inconsistencies, a large proportion of hip replacement admissions on Thursday and Friday, the government ownership status, the bed size, and the critical access status are associated with an increased LOS. On the other hand, the rate of hip replacement admissions over total ones, and the hospital being accredited, are associated with a lower LOS. Findings stress out the need for hospitals to maintain an effective and balanced distribution of hip replacement admissions, evenly during the week, and the need for standardized case management, to avoid practice variability and, therefore, LOS fluctuations for their hip replacement cases.

The aim of this paper was to describe the seasonal patterns of Chrysomelidae and of its most abundant species at eight sites in different geomorphological and floristic regions in the state of Paraná, southern Brazil. Samples with Malaise traps, from August 1986 to July 1988 were performed. The Chrysomelidae showed seasonal patterns with the highest abundance in the spring and/or summer at all sites, but with variations in the months of highest captures. Photoperiod was the variable that most influenced the seasonality of Chrysomelidae, and along with temperature and relative humidity, determined most of the seasonal patterns of the family at the different sites. Some dominant species of Chrysomelidae showed different seasonal pattern compared to the family level. A better knowledge of the seasonal distribution patterns of these species will only be possible when their life history, such as host plants and behavior, was better understood.

In regularly burned grassland on Morro Santana, Porto Alegre, RS, Brazil, we investigated differences in the floristic composition and their relation to soil properties, aspect and distance from the forest border. In 48 plots of 0.75 m², we identified a total of 201 species from a local species pool of approximately 450 to 500 species. Most species occurred in low frequencies, showing clumpy distribution patterns in the studied area. Multivariate analysis showed that plots close to the forest edge clearly differed from plots in the open grassland concerning composition and structure. Plots exposed to the north differed from plots on the top of the hill both in the composition of species as well as in soil variables, mainly due to shallower soil in the former. No strong relation between soil properties and variation in vegetation composition could be detected at a finer scale. The studied grassland, as all grassland vegetation in southern Brazil, is very rich in species compared to other grassland formations worldwide. However, this high biodiversity and conservational value of Campos vegetation in general has so far not been recognized properly. Disturbance is essential to maintain this open vegetation type and its species richness. Fire should be considered as a management option in the absence of grazing.

Open and species-poor stands with a dominance of <em>Alisma lanceolatum</em> were recorded in periodically flooded habitats of the southern part of central Slovakia (Ipeľ River catchment area) during the summer of 2013. Phytosociological relevés correspond to the association <em>Eleocharito palustris-Alismatetum lanceolati</em> (alliance <em>Eleocharito palustris-Sagittarion sagittifoliae</em>), which is reported and documented here for the first time from the territory of Slovakia. It inhabits predominantly temporarily flooded depressions on agricultural land – wet arable fields and extensively used pastures. Detrended correspondence analysis showed that the variability in species composition was most significantly influenced by water depth, the presence of arable fields in the contact area and water conductivity. Special attention was paid to a detailed description of the floristic composition, habitat requirements, distribution patterns and nomenclature of the community.

Objective: To examine the association between Anxiety Disorders (AD) and cognitive performance in young mothers at 30 months postpartum. Methods:  This is a cross-sectional study nested to a follow-up study was conducted with 539 young mothers in the city of Pelotas, in southern Brazil. The ADs were evaluated with the Mini International Neuropsychiatric Interview (MINI PLUS), cognitive performance was screened with the Montreal Cognitive Assessment (MoCA). We used multiple linear regression analysis to explore the association between ADs and cognitive performance. Results: The total MoCA score was associated with the following variables: marital status β= -0.86 (95%CI -1.60;-0.13), education β= 1.22 (95%CI 0.90;1.53), occupation β= 1.03 (95%CI 0.28;1.79), Generalized Anxiety Disorder (GAD) β= -2.28 (95%CI -4.07;-0.50) and at least one AD 30 months postpartum β= -0.10 (95%CI -0.20;-0.00). Together, these variables were responsible for 16% of the variance in the total MoCA score, GAD being the variable with the strongest negative association. Conclusions: The results showed that sociodemographic variables, a GAD diagnosis and the presence of at least one AD were significantly associated with low cognitive performance in young mothers at 30 months postpartum.

Acoustic Activity

Baseline knowledge of spatial and temporal distribution patterns is essential for cetacean management and conservation. Such knowledge is particularly important in areas where gillnet fishing occurs, as the Upper Gulf of California, which increases the probability of bycatch of cetaceans. In this area, the vaquita porpoise (Phocoena sinus) has been widely studied, but the knowledge of other cetaceans is scarce and based on traditional visual survey methods. We used data collected by an array of acoustic click detectors (C-PODs) during the summers 2011 to 2015 to analyze the distribution of dolphins in the Vaquita Refuge in the Upper Gulf of California. We recorded 120,038 echolocation click trains of dolphins during 12,371 days of recording effort at 46 sampling sites. Based on simultaneous visual and acoustic data, we estimated a false positive acoustic detection rate of 19.4%. Dolphin acoustic activity varied among sites, with higher activity in the east of the Vaquita Refuge. Acoustic activity was higher at night than during the day. We used negative binomial generalized linear models to study the count of clicks of dolphins in relation to spatial, temporal, physical, biological and anthropogenic explanatory variables. The best model selected for the response variable included sampling site, day-night condition, and vertical component of tide speed. Patterns in the spatial distribution of predicted acoustic activity of dolphins were similar to the acoustic activity observed per sampling season. Higher acoustic activity was predicted at night, but the tide speed variable was not relevant under this condition. Acoustic activity patterns could be related to the availability of prey resources since echolocation click trains are associated with foraging activities of dolphins. This is the first study of the distribution of dolphins in Mexico using medium-term systematic passive acoustic monitoring, and the results can contribute to better management to the natural protected area located in the Upper Gulf of California.
