A test of community assembly rules using foliar endophytes from a tropical forest canopy ArchiMer
Donald, Julian; Roy, Mélanie; Suescun, Uxue; Iribar, Amaia; Manzi, Sophie; Péllissier, Léonie; Gaucher, Philippe; Chave, Jérôme.
1.Community assembly theory assumes that ecological communities are spatially delimited into patches. Within these patches, coexistence results from environmental filtering, competition, and immigration. Truly delineated communities exist in laboratory studies of microbial cultures in Petri dishes, yet empirical tests conducted in continuous environments often use patches defined by convention as opposed to realised boundaries. 2.Here we perform a test of ecological community assembly rules using foliar endophyte communities from a tropical rainforest, where leaves are considered as patches for both fungal and bacterial communities. We determined the diversity of fungal and bacterial endophytes using environmental DNA sequencing of 365 top‐canopy leaves,...

Amazon Forest maintenance as a source of environmental services Anais da ABC (AABC)
Fearnside,Philip M..
Amazonian forest produces environmental services such as maintenance of biodiversity, water cycling and carbon stocks. These services have a much greater value to human society than do the timber, beef and other products that are obtained by destroying the forest. Yet institutional mechanisms are still lacking to transform the value of the standing forest into the foundation of an economy based on maintaining rather than destroying this ecosystem. Forest management for commodities such as timber and non-timber forest products faces severe limitations and inherent contradictions unless income is supplemented based on environmenta lservices. Amazon forest is threatened by deforestation, logging, forest fires and climate change. Measures to avoid...

Anurans from preserved and disturbed areas of Atlantic Forest in the region of Etá Farm, municipality of Sete Barras, state of São Paulo, Brazil Biota Neotropica
Fiorillo,Bruno Ferreto; Faria,Carolina Sconfienza; Silva,Bruno Rocha; Martins,Marcio.
Abstract: We provide information on the diversity and natural history of anurans from preserved and disturbed habitats in the region of Etá Farm, municipality of Sete Barras, state of São Paulo, Brazil. The region is covered by rainforest and plantations of banana and peach palm. From April, 2013 to March, 2014 we sampled amphibians mainly with pitfall traps with drift fences and visual and auditory surveys. A total of 9813 individuals of 36 species of anurans from nine families were recorded in this study. A larger number of species was found in forests (29 species), followed by peach palm plantations (21 species), and banana plantations (17 species). The areas of peach palm plantation and forests showed the greatest similarity in species composition. The...

Are fungivorous Scarabaeidae less specialist? Ecología austral
Falqueto,Silvia A; Vaz-De-Mello,Fernando Z; Schoereder,José H.
In a tropical forest patch of Southeastern Brazil, adult Scarabaeidae beetles were used to test the hypothesis that fungivorous guilds have a higher proportion of generalist species than either frugivorous, necrophagous or coprophagous ones. No significant differences were found between guilds in relation to either the proportion of generalists or niche breadths of the component species. Only two fungivorous specialist species were sampled. These results indicate that sporocarps eaten by Scarabaeidae are not as rare as literature suggests. Fungi may help maintain high species diversity of Scarabaeidae in tropical forests.

Birds - Their importance to visitors to an Australian Rainforest AgEcon
Tisdell, Clement A.; Wilson, Clevo.
Lamington National Park in Queensland, Australia is noted for its rainforest and is part of Australia’s fourteen World Heritage listed properties but no systematic study has been done of the importance of birds to its visitors. This study rectifies this situation. It is based on data from survey forms handed to visitors at an important site in this park and completed by visitors following their visit. This yielded 622 useable replies. These enabled us to establish the comparative importance of birds as an attraction to this site. Furthermore, logit regression is used to analyze and to identify factors that increase the likelihood of a visitor saying that birds are an important attraction. In addition, the relative importance to visitors of various...

Characterization saprobic fungi on leaf litter of two species of trees in the Atlantic Forest, Brazil BJM
Costa,Loise Araujo; Gusmão,Luís Fernando Pascholati.
Abstract We investigated the composition and structure of fungal communities associated with leaf litter generated by Clusia nemorosa and Vismia guianensis that belong to phylogenetically-related botanical families and exist together in a remnant of the Atlantic Forest in Bahia, Brazil. Samplings were conducted during wet (June 2011) and dry (January 2013) seasons in Serra da Jibóia. The fungi were isolated using particle filtration and the 1,832 isolates represented 92 taxa. The wet season yielded the largest number of isolates (1,141) and taxa (76) compared with the dry season (641 isolates and 37 taxa). The richness and diversity of fungal species associated with C. nemorosa (64 taxa, Simpson=0.95)were higher compared with those of V.guianensis (59...

Chironomidae from Eastern Amazon: understanding the differences of land-use on functional feeding groups. Repositório Alice
SONODA, K. C.; MONTELES, J. S.; FERREIRA, A.; GERHARD, P..
Abstract: Deforestation for agricultural purposes is the most dangerous human action against the conservation of the Brazilian Amazon Forest; its rates reached almost 20% of the original forested area. Many studies have been conducted on Chironomidae systematics and ecology over the Amazon biome, but most concerned the Central Amazon, while little is known about Chironomidae diversity and the effects of land development and agriculture intensification on the aquatic biota from Eastern Brazilian Amazon. The present study analyzed the effects of different land-use and land-cover on Chironomidae assemblages. Land-Use and Land-Cover (LULC) at the riparian zone were assessed from satellite imagery and three categories were defined: Forest, Secondary (Capoeira)...

Diet of the lizard Ecpleopus gaudichaudii (Gymnophthalmidae) in Atlantic Rainforest, state of Rio de Janeiro, Brazil Rev. Bras. Zool.
Maia,Thiago; Almeida-Gomes,Mauricio; Siqueira,Carla C.; Vrcibradic,Davor; Kiefer,Mara C.; Rocha,Carlos Frederico D..
In this study we analyzed the diet of the gymnophthalmid lizard Ecpleopus gaudichaudii Duméril & Bibron, 1839, a typical inhabitant of the forest-floor leaf litter, in an Atlantic Forest area in the state of Rio de Janeiro, southeastern Brazil. The 26 individuals sampled during the study had a mean snout-vent length (SVL) of 36.2 ± 4.2 mm and a mean jaw width (JW) of 4.1 ± 0.5 mm. We did not find differences in SVL between males and females, though the sexes differed in JW when the effect of body size was factored out, with females presenting higher values. The diet of the lizards was composed exclusively of arthropods, especially isopods and orthopterans. The similarity in trophic niches among seasons (volumetric and numerical proportions of prey...

Effect of species and log diameter on the volumetric yield of lumber in northern Brazilian Amazonia: preliminary results. Repositório Alice
LIMA, R. B. de; FERREIRA, R. L. C.; SILVA, J. A. A. da; GUEDES, M. C.; SILVA, D. A. S. da; OLIVEIRA, C. P. de; RABELO, F. G.; SILVA, L. F. da C..
Volumetric yield analysis is critical to optimizing performance in the timber industry. In the Amazon and in the Amapá state, this information is still little known and scarce, and therefore this study was developed to obtain and analyze the volumetric yield coefficient of ten commercial tree species and to test the variation by diameter class. We collect data of volumetric yield from for ten commercial species. For each species, the yields in different diameter classes were analyzed, as well as the yield difference between the species. The overall yield obtained for the sawmills (43.95%) and the yield of each species are within the established standards for operations in the industry according to the legal requirements.

Environmental and ecological architects: Guidelines for the Chilean temperate rainforest management derived from the monito del monte (Dromiciops gliroides) conservation RChHN
FONTÚRBEL,FRANCISCO E; JIMÉNEZ,JAIME E.
Land use change is one of the main biodiversity threats. Due to this change, natural habitats such as the South American temperate rainforests have been rapidly degraded, fragmented, and lost. Consequently, the management and conservation of the remaining forest is a priority and having an appropriate environmental policy is mandatory for this purpose. Conservation actions in the temperate rainforest have been addressed from an individual species perspective, giving less attention to the ecosystem level conservation. Moreover, conservation-related information has not reflected yet on environmental policy development. We used the case study of the monito del monte (Dromiciops gliroides) to illustrate how our current ecological and conservation knowledge of...

Filling gaps in the distribution of the white-winged vampire bat, Diaemus youngii (Phyllostomidae, Desmodontinae): new records for southern Amazonia Acta Amazonica
PEDROSO,Mônica A.; ROCHA,Patrício A. da; BRANDÃO,Marcus V.; GARBINO,Guilherme S. T.; MORAES,Carolina O. de; AIRES,Caroline C..
ABSTRACT Bats of the subfamily Desmodontinae are the only hematophagous mammals, represented by three species. Among them, Diaemus youngii has the fewest records in Brazil, being poorly known demographically and ecologically. We report the first record of D. youngii for Mato Grosso state, in central-western Brazil, and provide additional records for the states of Rondônia and Tocantins, in northern Brazil, extending the known distribution of D. youngii in the southern Amazon region.

From forest to cropland and pasture systems: a critical review of soil organic carbon stocks changes in Amazonia. Repositório Alice
FUJISAKI, K.; PERRIN, A.-S.; DESJARDINS, T.; BERNOUX, M.; BALBINO, L. C.; BROSSARD, M..
Abstract - The impact of deforestation on soil organic carbon (SOC) stocks is important in the context of climate change and agricultural soil use. Trends of SOC stock changes after agroecosystem establishment vary according to the spatial scale considered, and factors explaining these trends may differ sometimes according to meta-analyses. We have reviewed the knowledge about changes in SOC stocks in Amazonia after the establishment of pasture or cropland, sought relationships between observed changes and soil, climatic variables and management practices, and synthesized the ?13C measured in pastures. Our dataset consisted of 21 studies mostly synchronic, across 52 sites (Brazil, Colombia, French Guiana, Suriname), totalling 70 forest?agroecosystem...

Modelling Amazonian forest eddy covariance data: a comparison of big leaf versus sun/shade models for the C-14 tower at Manaus I. Canopy photosynthesis Acta Amazonica
Mercado,Lina; Lloyd,Jon; Carswell,Fiona; Malhi,Yadvinder; Meir,Patrick; Nobre,Antonio Donato.
In this study, we concentrate on modelling gross primary productivity using two simple approaches to simulate canopy photosynthesis: "big leaf" and "sun/shade" models. Two approaches for calibration are used: scaling up of canopy photosynthetic parameters from the leaf to the canopy level and fitting canopy biochemistry to eddy covariance fluxes. Validation of the models is achieved by using eddy covariance data from the LBA site C14. Comparing the performance of both models we conclude that numerically (in terms of goodness of fit) and qualitatively, (in terms of residual response to different environmental variables) sun/shade does a better job. Compared to the sun/shade model, the big leaf model shows a lower goodness of fit and fails to respond to...

New genus of Psychodinae (Diptera, Psychodidae) from Argentina Iheringia, Sér. Zool.
Omad,Guillermo; Mangudo,Carolina; Gleiser,Raquel M..
ABSTRACT Adults (male and female) and pupae of Chuspilepia saltenia gen. nov., sp. nov. were collected in tree holes in the Yungas rainforest, near San Ramón de la Nueva Orán city, Salta province, Argentina. It was not possible to place this new species in any known genera using the available keys and published descriptions, thus a new genus is proposed for the Neotropical region of Argentina.

The known distribution of Perichaena calongei, P. chrysosperma, P. corticalis, P. depressa, P. microspora, P. pedata and P. vermicularis in the nine states that comprise Brazil's Northeast Region (1,548,672 km2) is presented herein, enhancing our understanding of the distribution of the genusPerichaena (Trichiaceae, Myxomycetes) in the Neotropics. This inventory encompasses a 100-year period (1914-2014), and analyzes material deposited in herbaria and collected by the authors. The collected material came from areas of thorny deciduous vegetation typical of the Caatinga biome and portions of savannah in the continent's interior, rainforests,restingas (tropical moist broadleaf forests found along Brazil's coastal spits) and mangroves of the Atlantic Forest...

On the diagnostic characters, ecogeographic distribution, and phylogenetic relationships of Gracilinanus emiliae (Didelphimorphia: Didelphidae: Thylamyini) Mastozool. neotrop.
Voss,Robert S.; Fleck,David W.; Jansa,Sharon A..
Gracilinanus emiliae is a species of gracile mouse opossum that is currently known from fewer than a dozen specimens. The material we examined exhibits a distinctive suite of external and craniodental characters that are unlike those of any other congeneric species. We review all published records for G. emiliae, several of which are based on misidentifications or lost material, and we report a new specimen from northeastern Peru, the first to be recorded from that country, and the first to be unequivocally associated with primary lowland rain forest. The available distributional data suggest that G. emiliae (or a complex of cryptic taxa with the same morphological characters) is very widely distributed in Amazonia and perhaps also in Venezuelan coastal...

Preventing injuries caused by radiotelemetry collars in reintroduced red-rumped agoutis, Dasyprocta leporina (Rodentia: Dasyproctidae), in Atlantic Forest, southeastern Brazil Rev. Bras. Zool.
Cid,Bruno; Costa,Rodrigo de C. da; Balthazar,Daniel de A.; Augusto,Anderson M.; Pires,Alexandra S.; Fernandez,Fernando A. S..
Reintroduction has been recognized as a powerful conservation tool, but in order to ensure its success, animal monitoring is highly recommended. One way to monitor released animals is to put radiotelemetry collars on them. These devices, however, can harm the subjects, causing serious wounds. Our objectives in this work were to describe the injuries caused by a radiotelemetry collar model on reintroduced agoutis and to propose modifications to it. We equipped agoutis with TXE-311C radio collars (Telenax Wildlife Telemetry) before releasing them in the wild. They acquired serious wounds and one animal died. We then modified the collar structure to reduce its width and retention of water. After these modifications, the injuries did not occur again. As...

Range extension of Centronycetris maximiliani (Mammalia: Chiroptera) for southern Amazonia Acta Amazonica
ROCHA,Patrício A. da; BRANDÃO,Marcus V.; OLIVEIRA JÚNIOR,Adalberto Césari de; AIRES,Caroline Cotrim.
Bat species of the genus Centronycteris are some of the rarest Neotropical Emballonuridae and fewer than 50 specimens have been deposited in scientific collections. The aim of this study is to extend the distribution of Centronycteris maximiliani. Three C. maximiliani specimens were recorded in the Brazilian Amazonia, providing the first record of the species for the state of Rondônia, the southernmost record of the species for the Amazon biome in Brazil, and an additional record for the state of Pará. Although these new records of C. maximiliani reinforce the idea that this species is widely distributed throughout the Amazon biome, its low capture rate reflects the rarity of this species, since only three specimens were collected during three to four year...

Spotlight on Plasmodium falciparum evolutionary system in the southeastern Atlantic forest Biota Neotropica
Laporta,Gabriel Zorello.
Abstract Malaria elimination is now set to occur in Brazil until 2030. While this achievement is feasible, as it is for other endemic regions worldwide, it is important to recognize resistance of parasites and vectors against anti-malarial interventions. Resistance against drugs and insecticides can lead to discontinuities of malaria transmission, known as residual malaria transmission. Herein, we described a novel phenomenon that is occurring in a residual malaria transmission scenario in the southeastern Atlantic forest. This novel phenomenon does not belong to what is known and therefore we decided to explain it based on an evolutionary perspective. Although it shall not be viewed as a threat to public health, the phenomenon has important aspects that...
