This study presents a list of anurans and lizards of a Central Amazonian terra-firme rainforest site at Rio Preto da Eva, Amazonas, Brazil sampled for 38 days from December 2003 to February 2004. The study area is located close to highway AM-010 (Manaus-Itacoatiara), where deforestation represents the main threat to the local biota. Using two complementary sampling methods, active search and pitfall traps with drift fence, we recorded 23 anuran species in 12 genera and six families and 20 lizard species in 16 genera and seven families. Relative to other sites in Central Amazon, our study site presented a similar number of species of lizards but fewer amphibians.

On The Road

We present the first lizard species list for the municipality of Juruti, state of Pará, Brazil. The list was drawn up as a result of data obtained from specimens deposited in the Herpetological Collection of the Museu Paraense Emílio Goeldi and from inventories conducted in 2008-2011. Sampling methods included pitfall traps with drift fences and time constrained searches. We considered the data collected by other researchers, incidental encounters and records of dead individuals on the road. We recorded 33 species, 26 genera and ten families. Norops tandai was the most abundant species. Compared with the other regions of Amazonia, the region of Juruti presented a large number of lizards. However, further studies with an increase in the sampling effort, could prove this area to be richer in lizards than that observed so far.

Faunal Similarity

The present study reports an inventory of lizard species from a region at the central Jatapú River located in the state of Amazonas, Brazil. The lizard fauna was surveyed using three sampling methods: diurnal and nocturnal visual search, pitfall traps with drift fences, and incidental collections. We recorded 24 lizard species belonging to 18 genera and eight families. Non-parametric estimators of richness (Bootstrap, Chao 2, Jackknife 1, Ace) were used to estimate the percentage of total richness sampled. Expected species richness varied from 27 species estimated via Bootstrap to 30 species with Jackknife 1. The composition of the lizard fauna encountered in the rio Jatapú plot was compared with seven other published surveys carried out in the region of the Brazilian Guiana Shield. The composition of the Jatapú lizard fauna was most similar to FLOTA Faro (84%) and least similar to ESEC Grão-Pará Center (66%). There was no association between faunal similarity and geographic distance. The present species list contributes to our knowledge of lizards of the southern portion of the Guiana Shield in Brazil.

There are different methodologies used to make an inventory of social wasps. In general, these methods are divided into active search and passive collections. Each method has a different performance, depending on the environment in which the collection is being carried out. Thus, the choice for the proper methodology according to the study area will impact the success of sampled species. This study aimed to evaluate the performance of sampling methodologies for social wasps (active search and bait traps) in different phytophysiognomies (Regenerating Cerrado, “Cerradão”, Restored Forest, Semideciduous Forest and Riparian Forest) in the state of São Paulo, Southeastern Brazil. The active search sampled a greater number of species, with the exception of the Regenerating Cerrado. Regarding abundance, the active search was also more efficient, except in “Cerradão”, where there was no difference between the methods, and in Regenerating Cerrado, where the traps sampled a higher number of individuals. The fact that none of the methods collected all the sampled species indicates that it is appropriate to use more than one collection method in order to obtain a sampling closer to the true richness of the studied sites.

Changes in the floristic composition over an eight-year period in a logged area at the Tapajós National Forest in Brazilian Amazonia arc discussed. Two treatments of different intensities of logging were compared with an undisturbed (control) forest. Data were collected from permanent sample-plots. The effects of logging on floristic composition were stronger in the more heavily logged treatment. The number of species decreased immediately after logging, but started to increase before the fifth year after logging and was higher at the end of the study period than before logging. The more heavily logged plots responded more to disturbances, as judged by the increase in the number of species during the period after logging. This forest appears to recover its initial floristic composition after disturbance without intervention.

On The Road

We present the first species amphibian list for municipality of Coari, state of Amazonas, Brazil. The list was drawn up as a result of data obtained from specimens deposited in the Herpetological Collection of the Museu Paraense Emílio Goeldi and inventories conducted in the Urucu Petrol Base, in 2003-2004 and 2007-2009. Sampling methods included pitfall traps with drift fences and time constrained searches. We considered the data collected by other researchers, incidental encounters and records of dead individual on the road. Fifty four species were recorded. Rhinella gr. margaritifera (n= 68), Adenomera gr. marmorata (n= 59), and Osteocephalus leprieurii (n= 20) were the most collected, while ten species were less collected. Compared with other studies in eastern Amazonia, the region of Urucu presented a large number of anurans. Nonetheless, it ́s not possible to confirm this because the data collected were not standardized among studies. However, further studies by, increasing the sampling effort, could prove this area to be richer in anurans than that observed so far.

AbstractAnnual patterns of breeding activity of 28 anuran species were studied at Boracéia, an Atlantic Rainforest locality in the coastal mountains of Southeastern Brazil. Five patterns were evident: (1) species that call year-round; (2) opportunistic calling activity associated with rainfall; (3) explosive breeding; (4) winter activity; and (5) summer species with variable breeding seasons. The number of species with calling males was positively correlated with mean monthly temperature.

Collecting Techniques

The shining fungus beetles (Coleoptera: Staphylinidae: Scaphidiinae) comprise more than 1800 described species, which are usually small (≅0.84–14.30 mm long) (Tang et al. 2014 ; Löbl & Ogawa 2016) and found on bracket and resupinate fungi, mushrooms and slime molds (Newton 1984; Löbl & Leschen 2003; Löbl 2018). They are known to be diverse in forests of tropical and subtropical regions, which contrast to the low number of species currently known from Brazil: only 34 species and two subspecies from seven genera (Löbl 2018; von Groll & Lopes-Andrade, 2021). Any active search for Scaphidiinae in the Brazilian Atlantic forest reveals a considerable abundance and diverse of these organisms (pers. obs.), but they disperse rapidly if disturbed, and the success of field collections relies on the collectors’ skills, luck and collecting techniques and devices. The most common methods and devices for collecting shinning fungus beetles are sifting leaf litter, rotten wood and fungi, flight intercept (FIT) and V-flight intercept (V-FIT) traps, aspirators, sweeping, and hand collecting (Löbl & Leschen 2003; Tang et al. 2014; Löbl et al. 2021). Hand collecting is considered the best method, because the host fungi and larvae can be collected together to make associations (Löbl & Leschen 2003).

Fish Spawning

Wet–dry tropical rivers are characterised by highly predictable, yet highly variable, seasonal flow regimes. The wet season is often regarded as an important period of ecosystem productivity, dispersal and connectivity, and also for freshwater-fish spawning and recruitment. However, few studies have examined fish spawning across hydrological seasons in these rivers. We conducted a pilot study to determine (1) the temporal occurrence (and hence spawning period), and (2) the suitability of standard sampling methods of young fish in the Daly River, Northern Territory, Australia. Fish spawned throughout the year, with spawning phenologies varying substantially among species. The highest diversity and abundance of young fish occurred during the wet season, although early life stages of a high number of species were also present in the dry-season and transition periods. A high number of species spawned all year round, whereas other species had very discrete spawning periods. Three of the four sampling methods tested were successful in catching early life stages and should be employed in future studies. The present study highlighted that all hydrological seasons in the wet–dry tropics are important for fish spawning, and has important implications for future research on the drivers of spawning patterns, and for predicting the effects of flow modifications on freshwater fishes of the wet–dry tropics.

The Relationship

This study aimed to verify the relationship between habitat and the composition of anuran species in dune and restinga habitats in southernmost Brazil. The habitats were sampled between April 2009 and March 2010 using pitfalls with drift fence. We have captured 13,508 individuals of 12 anuran species. Species richness was lower in the dunes and dominance was higher in the resting. Apparently the less complex plant cover, water availability, and wide daily thermal variation in dunes act as an environmental filter for frogs. This hypothesis is reinforced by the fact that the most abundant species (Physalaemus biligonigerus and Odonthoprynus maisuma) bury themselves in the sand, minimizing these environmental stresses. Despite being in the Pampa biome, the studied community was more similar to those of coastal restinga environment of southeast Brazil than with other of the Pampa biome. The number of recorded species is similar to those observed in other open habitats in Brazil, showing the importance of adjacent ones to the shoreline for the maintenance of the diversity of anurans in southernmost Brazil.
