This study provides a comprehensive checklist of Odonata species from the protected area of Mananciais da Serra. The survey was conducted in the endangered Atlantic Forest domain at the southern Serra do Mar mountain chain within a well-preserved area in the municipality of Piraquara, state of Paraná, Brazil. Adults and larvae were sampled between June 2017 and March 2020 using different techniques in numerous mesohabitats, including phytotelmata, pools, small streams, and large reservoirs. A total of 1,708 specimens from 9 families, 43 genera and 84 species were sampled resulting in 53 new records for the state of Paraná, almost doubling the known occurrence records for dragonflies and damselflies in that state. Furthermore, two hitherto undescribed females from the genera Planiplax and Heteragrion, four ultimate stadium larvae from Planiplax, Neocordulia, Heteragrion, and Acanthagrion, and five undescribed species were detected, one each from the genera Heteragrion, Progomphus, Brechmorhoga, Erythrodiplax, and Dasythemis. The estimated richness of odonates in this area is greater than 100 species, while the observed richness corresponding to almost 10% of all Odonata species in Brazil, the species-richest country in the world. These results reiterate the need to investigate undersampled areas to improve knowledge on diversity, taxonomy, and distribution of neotropical species. Finally, taxonomic notes for some species, including the rare corduliid Neocordulia mambucabensis Costa & T.C. Santos, 2000, are provided.

Experiments were carried out to study the effects of ammonia and nitrite on food consumption of Macrobrachium amazonicum postlarvae. Postlarvae (average weight of 0.0625 g) were exposed during 21 days to four concentrations of total ammonia (0, 1.05, 2.1 and 4.2 mg. NH 3 +NH 4 + L -1 ) and four concentrations of nitrite (0, 0.075, 0.15 and 0.30 mg N-NO 2 - L -1 ). After the exposure period, six prawns per treatment were maintained individually in 250 mL experimental units to analyze the food consumption as a function of the amount of food offered and the leftovers during a 24 h period. The food consumption presented significant alterations for prawns exposed to all nitrite concentrations and at concentrations of twice the recommended safety level for total ammonia. According to the results obtained, high concentrations of total ammonia and nitrite affect the food consumption of M. amazonicum adversely, influencing the species performance in culture systems.

This study evaluated the effect of the addition of biomass and aqueous extract of the green microalga Desmodesmus subspicatus on asymbiotic germination and seedling development in the orchid Cattleya warneri. Seeds were germinated in MS culture medium with the macronutrients reduced by half (MSM/2), supplemented with 0, 0.25, 0.5, 1.0, and 2.0 g L−1 of microalgal biomass or its aqueous extract. Chlorophyllous protocorms were observed at 4 weeks and the addition of biomass or extract (0.25 g L−1) accelerated germination. Twenty-four weeks after sowing high percentages of seedlings (greater than 95%) were observed in all treatments with biomass, as well as with the addition of 0.25 or 0.5 g L−1 of microalgal extract. Shoot elongation and root development were increased in the semi-solid medium supplemented with 2.0 g L−1 of activated charcoal. Plantlets cultivated in a double-phase medium (a thin layer of liquid medium, containing 0.5 to 2 g L−1 of extract on the semi-solid medium) demonstrated the positive effect of zeatin on the formation of new shoots and plants. Plantlets were successfully acclimatized, showing high percentages of survival (over 80%) with foliar sprays of 2.0 g L−1 of biomass or 1.0 g L−1 extract for 4 months. The addition of D. subspicatus biomass or extract accelerated germination, induced shoot formation, and produced well-developed seedlings during acclimatization. A complete and efficient protocol of germination and seedling development of C. warneri was therefore achieved using biomass and aqueous extract of D. subspicatus.

The Atlantic Forest, a hotspot for biodiversity conservation, harbours five forest deer species (Mazama spp.). Due to their elusiveness, there is a severe scarcity of occurrence data to support ecological studies and conservation planning. Thus, we assembled an occurrence dataset of Atlantic Forest deer with reliable taxonomic information aggregating data from scat and camera traps surveys, and opportunistic data collection over the last 20 years. From 2002 to 2019, we surveyed 77 protected areas using scats detection dogs and genetically identifying the faecal samples. We successfully identified 1,147 out of 1,450 collected samples. From 2000 to 2020, we sampled six protected areas in 92 sampling points with 13,328 camera trap days of sampling effort. In addition, we established an active search for potential contributors within the scientific community and environmental consultants since 2010, offering a taxonomic identification service for camera traps images, and biological field-collected samples. With our efforts, we assembled a dataset with 1,456 records of forest deer occurrence at the Atlantic Forest. Of these records, 494 are from M. americana, 350 from M. bororo, 309 from M. gouazoubira, 268 from M. nana and 35 from M. nemorivaga. The faecal sampling was the most predominant method in these records (n = 1043) followed by photographs from camera traps (n = 388); both methods represent 98.2% of our dataset records. Most of the records (79.5%) in the dataset are inside protected areas (n = 1,130). Our dataset is the most comprehensive source of information on Neotropical forest deer occurrence to date.
