One of the largest populations of crocodiles in Costa Rica is located at the Tempisque River. The species is threatened by habitat loss and poaching; but its populations have grown due to the protection given by law. The research was conducted in Guanacaste, Costa Rica. We made a characterization of popular knowledge, activities and perceptions of 374 residents of the study area. It was found that 55% believe that the crocodiles are abundant, 70% believe that populations have increased. The most dangerous activities done are recreation, swimming and fishing. There are significant differences between the proportions of response (X2: 71, n = 10, p <0.0001 X2). These activities are done daily (25%), weekly (30%), monthly (18%) and annually (10%). The risk of attack and the crocodile’s density in the river are not recognized. Also, a lack of knowledge about the natural history and ecology of the species is shown. The reasons for attacks are: the aggressiveness of the animals and their density. There are differences in the responses on the reasons of the attacks (X2: 35, n 8 p <0.0001). Generally, the crocodile perception is unfavorable.

In Costa Rica, Patagioenas fasciata is distributed in forested areas of the highlands, from 900 m above sea level to the top of the ridges. We identified the main habitats of this species with thematic maps in GIS and did a geophysical analysis. The species is found in the highlands of Rincon de la Vieja, SanIgnacio de Acosta and San Vito de Coto Brus. Our information about possible migration routes, altitudes, weather elements and geomorphology of the sites where it moves and lives is relevant to the species’ management and conservation.

The work deals with the theme artisanal fisheries and has as main objective, the characterization of the activity in the municipalities of Tramandaí and Imbé, located in the State of Rio Grande do Sul, the spatial distribution and the challenges to occur fisheries in this region. The research is justified by the large number of fishermen in the study area and the economic importance of the activity, mapping through popular knowledge areas of greatest value for fishing, the main existing species and the main features and instruments used in fish capture.

Ecological and morphological data on Ungaliophis panamensis is extremely limited as this species is rarely encountered. These knowledge gaps have been advanced in this study where data was analysed from a small sample of snakes collected in two tropical forested environments in Costa Rica and Panama. Standardised major axis testing and a Bayesian latent variable ordination revealed that the species is sexually dimorphic, closely associated with tree trunks in natural forested areas, and occasionally discovered in rural buildings. Although further investigation into its natural history is warranted, this study shows that even with just a few individuals it is possible to elucidate ecological information that is relevant to the conservation of snake species.

Fusarium species produce toxic mycotoxins that are known to exert adverse health effects in humans and animals. No attempts have been made to establish mycotoxin-producing capabilities of isolates of Fusarium species from bananas exhibiting symptoms of crown rot. Crown rot is one of the most serious post harvest problems in banana and the disease is caused by different fungal species, principally Fusarium species. Banana, which is of great economic significance in growing countries (i.e. Costa Rica, Cameroon, Ecuador) is seriously affected by crown rot and is a major cause of fruit loss

In der Schleiftechnik besteht ein erhebliches Wissensdefizit über den Einfluss der Schleifscheibentopographie auf das Schleifprozessverhalten und die Ausbildung der Bauteilrandzoneneigenschaften. Ziel der Untersuchungen war daher die Identifikation und Analyse quantitativer Kenngrößen zur Beschreibung der geometrischen Schleifscheibentopographieeigenschaften. Diese Kenngrößen ermöglichten fortführend die Modellierung des thermo-mechanischen Belastungskollektivs im Schleifprozess in Abhängigkeit von der Schleifscheibentopographie. &nbsp; In grinding technology, there is a considerable lack of knowledge about the influence of the grinding wheel topography on the process behaviour and the formation of the component surface zone properties. Therefore, the aim of the investigations was to investigate quantitative parameters for the description of the geometrical topography properties. These parameters enable to model the thermo-mechanical load collective in the grinding process as a function of the grinding wheel topography.

The Scottish eighteenth-century philosopher and historian David Hume can be considered a pioneer of the “natural history of religion” in the sense of a universal history of religion that is not based on theological presuppositions. This chapter offers a characterization of his methodological achievements and a reevaluation of his empirical claims concerning monotheism, polytheism, religion and tolerance. It also interprets the German reception of Hume in Herder and other eighteenth-century thinkers as a serious critical continuation that is free from Hume’s anti-Christian motives. This continuation opens the perspective of a serious study of the literary character of religious texts, in this case of the Bible. All simple contrasts between Enlightenment and religion are overcome as soon as we take this interaction of thinkers into account.
