Abstract The diversity of montane environments is dictated by a variety of environmental conditions. Parque Estadual do Ibitipoca is located in the Serra da Mantiqueira, between ~1,000-1,800 m, and harbors approximately 300 ha of cloud forests. The composition of vascular epiphytes was determined by analyzing data from expeditions conducted between July 2014 and July 2015, and specimens deposited at herbaria. The 224 species were distributed into 82 genera of which Pleurothallis s.l. was the richest (13 spp.) and 23 families of which Orchidaceae was the richest (87 spp.). This richness corresponds to approximately 9.5% of the vascular epiphytic flora of the Atlantic Forest concentrated in an area that comprises 0.00085% of this phytogeographic domain, which represents one of the largest diversities ever sampled in the Brazilian Atlantic Forest. This fact is more relevant given that 13 species are threatened at the country level and 23 at the state level.

Rhipsalis Gaertner (1788: 138) belongs to Cactaceae Juss., which is among the major taxonomic groups including the highest numbers of threatened species in the world (Goettsch et al. 2015). The center of diversity and endemism of this genus is in the Atlantic Forest in Brazil, a world hotspot of biodiversity (Myers et al. 2000). This forests harbors 5% of all flowering plants species on the planet (Stehmann et al. 2009), including a high diversity of vascular epiphytes. Cactaceae is the sixth most expressive family in terms of number of epiphytes in the Atlantic Forest (2.2% of all vascular epiphyte species at the domain; Freitas et al. 2016) and Rhipsalis is the largest genus of epiphytic cacti (40 species according to Calvente 2012), highlighting the importance of this genus amongst the global epiphytic flora.

Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.

ABSTRACT While studying Croton material collected in Espírito Santo, we found several specimens of Croton sapiifolius, a species previously restricted to the State of Bahia. The present paper updates our knowledge about the taxonomy, habitat and geographic distribution of C. sapiifolius. This finding increases the number of known Croton species occurring in Espírito Santo State to 20 and contributes to the knowledge of Croton of the Brazilian Atlantic Forest.

We present the first record of the Dipsadidae snakes Xenopholis scalaris for the state of Rio de Janeiro and a general distribution map for this species. This record for the Brazilian Atlantic Forest expands the known geographical distribution of X. scalaris and reveals that its populations might not be isolated or disjunctive, but rather rare in this biome. We also provide some recommendations for future conservation of X. scalaris.

We report from three localities four new records of the threatened Brazilian Atlantic Forest endemic Chaetomys subspinosus (Olfers, 1818). These are the first records of this porcupine species from the state of Minas Gerais, and these new data extend the distribution of this species by approximately 220 km to the southwest. As C. subspinosus was observed in areas of transitional vegetation, this species may be found in a much broader spectrum of habitat types than previously thought. We recommend further surveys focusing on documenting this species.

The Brazilian Atlantic Forest has a rich biodiversity increasingly threatened by human activities. Since the colonial period, the coast of the state of Bahia is among the most affected regions of Brazil by anthropic pressure. Bahia encloses Atlantic Forest remnants distributed in an area reaching 100-200 km along the east-west axis, by 1,000 km along the north-south axis, parallel to the coast of the Atlantic Ocean. We report hereafter the results of an intensive field survey of leaf litter and epigaeic ants realized in forest remnants of the Atlantic Forest landscapes within the original extension of the biome in 11 localities distributed along four degrees of latitude in the state of Bahia. In each site, 16 plots were collected using pitfall and eight using Winkler traps. We identified 391 ant species belonging to 71 genera and nine subfamilies. Among all species recorded, 21 were common to the whole 11 localities, while 98 species were recorded in a single locality. This study highlights the richness and diversity of epigaeic and leaf-litter ants living in the northern part of the Brazilian Atlantic Forest, and is one of the most representative soil ants’ inventories ever done in this biome for a single state of Brazil.

Vascular Epiphyte

Arboreal epiphytes (plants residing in forest canopies) are present across all major climate zones and play important roles in forest biogeochemistry. The substantial water storage capacity per unit area of the epiphyte “bucket” is a key attribute underlying their capability to influence forest hydrological processes and their related mass and energy flows. It is commonly assumed that the epiphyte bucket remains saturated, or near-saturated, most of the time; thus, epiphytes (particularly vascular epiphytes) can store little precipitation, limiting their impact on the forest canopy water budget. We present evidence that contradicts this common assumption from (i) an examination of past research; (ii) new datasets on vascular epiphyte and epi-soil water relations at a tropical montane cloud forest (Monteverde, Costa Rica); and (iii) a global evaluation of non-vascular epiphyte saturation state using a process-based vegetation model, LiBry. All analyses found that the external and internal water storage capacity of epiphyte communities is highly dynamic and frequently available to intercept precipitation. Globally, non-vascular epiphytes spend <20% of their time near saturation and regionally, including the humid tropics, model results found that non-vascular epiphytes spend ~1/3 of their time in the dry state (0–10% of water storage capacity). Even data from Costa Rican cloud forest sites found the epiphyte community was saturated only 1/3 of the time and that internal leaf water storage was temporally dynamic enough to aid in precipitation interception. Analysis of the epi-soils associated with epiphytes further revealed the extent to which the epiphyte bucket emptied—as even the canopy soils were often <50% saturated (29–53% of all days observed). Results clearly show that the epiphyte bucket is more dynamic than currently assumed, meriting further research on epiphyte roles in precipitation interception, redistribution to the surface and chemical composition of “net” precipitation waters reaching the surface.
