Resumo. As abelhas Euglossina ocorrem exclusivamente na região neotropical, com cerca de 200 espécies descritas. Utilizando-se fragrâncias artificiais como iscas, é possível realizar levantamentos faunísticos e estudar diversos aspectos ecológicos do grupo. Com o intuito de contribuir ao conhecimento da biodiversidade dos brejos de altitude, no tocante às abelhas Euglossina, sete fragrâncias artificiais foram utilizadas como iscas em um remanescente na cidade de Areia, Paraíba, em distintos períodos climáticos. Foram coletados 2.981 machos pertencentes a 14 espécies de Euglossina. A abundância e a riqueza foram maiores no período de estiagem, havendo variação no horário de atividade de um período para o outro. De modo geral, no período chuvoso os machos foram mais ativos após as 11h e, no de estiagem, entre 8h e 11h. Euglossa carolina (Nemésio), Eulaema nigrita (Lepeletier) e Eulaema cingulata (Fabricius) foram as espécies mais abundantes nos dois períodos. Beta ionona foi a fragrância que atraiu o maior número de espécies e indivíduos. Seasonality and Daily Activity Patterns of Euglossina males (Hymenoptera: Apidae: Apini) and Preferences for Artificial Fragrances in a Montane Atlantic Forest Remnant, Paraíba Abstract. Euglossina bees are distributed exclusively in the Neotropical Region, with around 200 species described. By the usage of artificial fragrances as baits, it is possible to accomplish faunistic inventories and study several ecological aspects of the group. To contribute to the knowledge of the biodiversity of a Montane Atlantic Forest remnant, concerning to Euglossina, seven fragrances were used as baits in different climatic periods. A total of 2,981 males belonging to 14 species of Euglossina were collected. Abundance and richness were higher in the dry period. Changes in the daily activity patterns were observed from a period to the other. Generally, in the rainy season the males were more active after 11am and in the dry season between 8am and 11am. Euglossa carolina (Nemésio), Eulaema nigrita (Lepeletier) and Eulaema cingulata (Fabricius) were the most abundant species on both periods. Ionone beta was the fragrance which attracted more species and specimens.

Chapada dos Veadeiros National Park (CVNP) in central Brazil is one of the most important protected areas of Brazilian Cerrado yet the diversity that this park harbors remains unknown for many taxa. From 2006 to 2009, we studied the snake assemblage of CVNP to determine the species composition, abundance, seasonal and daily activity patterns, morphology, and habitat use. We documented 47 snake species from seven families within CVNP, with the most common species being Bothrops marmoratus, Oxyrhopus trigeminus, Crotalus durissus and Bothrops moojeni. The incidence of snakes was highly seasonal and appeared to be associated mainly with rainfall. Daily activity patterns revealed that the majority of snakes are strictly diurnal, whereas others are nocturnal or active during both periods. Species richness estimators suggest that more snake species than the 47 we documented likely occur within CVNP, indicating that it harbors one of the richest snake faunas among South American open biomes studied to date.

The seasonal and daily activity patterns of a Saskatchewan population of Crotalus viridus viridis is presented. Snakes emerged from hibernation in late April and migrated into the surrounding river valley and upland regions in early May. Adult migration preceded that of immature age-classes. Several gravid females occupied a rookery near the hibernaculum during the summer months and remained there until parturition. Females did not occupy this site in successive years and may have a biennial or greater reproductive cycle. Snakes returned to the hibernaculum in early September and remained active until early October. The behaviour of snakes in a field enclosure in response to time of day and body temperature (Tb) was recorded during the spring, summer, and fall. Significant differences in the Tb values of sunning, movement, and shading behaviours were noted. Gravid females were significantly more active in all seasons. However, no significant difference in mean Tb was found between males and females in the field, enclosure study, or laboratory thermal gradient. The observed greater level of activity may reflect the high energy demands of gravid females.

The purpose of this study was to examine the effects of participation in an aerobic exercise intervention on daily activity occurring outside of the structured exercise sessions. Participants were randomized into one of the following 4 conditions: 1) No-exercise, 2) Low volume, low intensity exercise (LVLI), 3) High volume, low intensity exercise (HVLI), 4) Low volume, high intensity (LVHI). Physical activity was measured over 7 days with an accelerometer at baseline and during week 8 of the intervention. Activity was defined as: sedentary behaviour (SED; < 100 counts/minute), light physical activity (LPA; 100 to 1951 counts/minute), moderate-to-vigorous physical activity (MVPA; ≥1952 counts/minute), and total physical activity (TPA; LPA + MVPA). Activity was quantified as average total minutes per day of each SED, LPA, MVPA, and TPA. A one-way ANOVA was used to determine if time spent in SED, LPA, MVPA, and TPA changed from baseline to week 8. Seventy-one participants (No-exercise; n=12, LVLI n=17, HVLI n=24, LVHI; n=18,) with a mean age of 54 y and waist circumference of 110 cm completed 8 weeks of the intervention. There were no significant differences in SED, LPA, MVPA, or TPA between groups at baseline. There was no significant change in SED, LPA, MVPA, or TPA at week 8 compared to baseline (p>0.05). Similarly, there were no significant differences in activity variables between exercise conditions. Our observations suggest that daily activity patterns do not change with the implementation of an exercise intervention in men and women.
