The complex vocalization of Scinax cardosoi (Anura: Hylidae), with comments on advertisement calls in the S. ruber Clade. The complex vocalization of Scinax cardosoi from a population of Minas Gerais in southeastern Brazil is described and compared with available acoustic data for the other species of the S. ruber Clade. Three distinct types of high-pitched, pulsed calls were identified, and are referred to as “short,” “long,” and “trilled” calls. Short calls (16–66 ms) resemble squeaks, and consist of a pulsed signal (8–28 pulses/call) with regular amplitude modulations throughout their duration; the amplitude peak occurs at about the midpoint of the call duration. Long calls (268–518 ms) resemble giggles, and have lower amplitude than short calls; typically, they consist of pulsed note series (1–6 notes/call). Trilled calls resemble insect chirps and have the lowest amplitude of the three call types; they consist of long (1.1–3.0 s) pulsed note series (9–25 notes/call). Acoustic data are taxonomically informative in the Scinax ruber Clade and provide phenotypic characters diagnosing S. cardosoi in addition to those features proposed in its original description. The vocalization repertoire of S. cardosoi resembles the complex vocal repertoires (i.e., multiple call types emitted in variable combinations) of members of the S. catharinae Clade more than some species of the S. ruber Clade, which tend to have simpler call structures (i.e., a single type of multipulsed note).

Acoustic Diagnosis

The vocalizations of Ololygon hiemalis, O. ranki, and O. canastrensis are redescribed to provide further details on their complex vocal repertoires. The acoustic diagnosis of O. hiemalis is updated in relation to congeners, especially with respect to the morphologically similar O. ranki, for which we also evaluate the morphological diagnosis of both species. Three distinct types of notes are recognized in the vocalization of the three species (short squawk-like, long squawk-like and click-like), which are emitted in distinct acoustic organizations. The main organization of the three species is herein referred as the call Type “A”, each of which has a multi-note structure composed of a series of short squawk-like notes with note-by-note increase in amplitude along call duration. The call Type A of O. hiemalis was not described in the species original description. That of topotypes of O. ranki structurally resembles the call described in the original species description. Likewise, The call Type A of O. canastrensis matches that described in the original species description. Although O. hiemalis and O. ranki are phenotypically indistinguishable, there are quantitative differences in some call traits. Many species of Ololygon have complex vocalizations consisting of, at least, two types of notes, which can be emitted in different combinations. Despite the complexity of acoustic emissions, the call Type A of many species seems to be phylogenetically conserved. Because calls sometimes are only briefly described, we emphasize the need for, and importance of, comprehensive characterizations of anuran vocalizations to support future acoustic comparisons

Ischnocnema izecksohni inhabits the gallery forests from the Quadrilátero Ferrífero, Southern Espinhaço range, state of Minas Gerais, southeastern Brazil, and it is considered endemic to this region. Its closest related species is I. nasuta according to the original description. We describe the advertisement call of I. izecksohni based on specimens recorded and collected at the municipality of Nova Lima, state of Minas Gerais, distant about 10 km straight line from its type locality. The advertisement call consists of a group of notes emitted sporadically without a regular interval between the calls. Call duration (n = 36 calls in four individuals) ranged from 1.03 to 1.85 s (= 1.52 ± 0.21 s) and the call rise time from 0.66 to 1.52 s (= 1.16 ± 0.25 s), with 34-57 notes per call (= 47.42 ± 6.03). Peak frequency ranged from 2250 to 2625 Hz, the dominant frequency from 1317.8 to 3128.0 Hz and interval between notes from 22.00 to 41.00 ms (= 28.63 ± 0.03 ms). From the examination of herpetological collections, morphological and bioacoustical data we extended the species known distribution ca. 200 km eastward, to ten new localities, all of them outside the Quadrilátero Ferrífero region, at the Mantiqueira mountain range. We analyzed color patterns and we find some dorsal patterns not described at the original description of I. izecksohni. We also make some comments concerning the taxonomic status of I. izecksohni and I. nasuta.

The orchid-bee fauna of ‘Reserva Particular do Patrimônio Natural Feliciano Miguel Abdala’, a 957-ha preserve of Atlantic Forest in eastern Minas Gerais, southeastern Brazil, was surveyed 12 years after the first inventory in the area. Orchid-bee males were actively collected with insect nets when attracted to seventeen chemical compounds used as scent baits. Three hundred and nineteen males belonging to nine species were collected during 40 hours in late December, 2011, when orchid bees are supposedly more active. Euglossa despecta Moure, 1968, one of the dominant species in the area 12 years ago, was not recorded in the present study. Eulaema nigrita Lepeletier, 1841, on the other hand, represented only 16% of the collected bees in 1999 and 61% in the present study. Possible causes and consequences of these changes are discussed.

AbstractThe advertisement call of Peltophryne florentinoi, an endemic toad from Zapata Swamp, Matanzas, Cuba, is described in terms of temporal properties and dominant frequency. A comparison with the advertisement calls produced by the other three species of large toads in Cuba (P. peltocephala, P. fustiger and P. taladai) is also provided. Like other large toads from Cuba, P. florentinoi produces advertisement calls with long duration (> 10 s), low dominant frequency (< 1 kHz), and a series of complex pulses that are composed of two to five sub-pulses. All temporal features of the P. florentinoi call are significantly different from P. fustiger calls: number of pulses, pulse duration, and pulse rate separates it from P. peltocephala. P. florentinoi differs from P. taladai in call duration, number of pulses, and pulse rate. The occurrence of different types of complex pulses differed in all species studied. Typically, P. florentinoi pulses contain three sub-pulses, P. taladai four, and P. fustiger and P. peltocephala contain two sub-pulses. The dominant frequency of the advertisement call of P. florentinoi did not differ from the other species' calls. Call duration and pulse rate are the most useful acoustic properties to distinguish P. florentinoi advertisement calls from those of the other three large Cuban toads.

What Matters

The study of anuran advertisement calls is very significant for it is an important premating premating mechanism. Herein we redescribe the advertisement call of Aplastodiscus arildae from an area near type-locality and describe the advertisement call of A. weygoldti comparing them to previously described advertisement calls of species of the genus Aplastodiscus. Both advertisement calls are simple, non-modulated calls, very similar to each other, but significantly different in what matters to call duration. We describe the first distress call registered for the genus, the distress call of A. arildae, that does not have rigid form and was only recorded for one individual. Some general notes of the genus Aplastodiscus are given.

AbstractAdvertisement calls of Discoglossus galganoi jeanneae from two localities in southern Spain and D. pictus scovazzi from Ceuta were analyzed. Call duration as well as ratio of pulse group intensities and durations clearly group D. pictus scovazzi with the other subspecies of D. pictus (pictus and auritus). The calls of the taxon jeanneae show some differences to calls of populations of D. g. galganoi from northern Spain, but are more similar to calls of D. g. galganoi than to those of D. pictus scovazzi. These data support the status of jeanneae as subspecies of galganoi.

Many species and infraspecific taxa in Mimosa are narrow endemics. Following the same pattern, two new Brazilian species of the genus, M. perplicata and M. serpensetosa are described, both from the Southern Espinhaço Range (one from Serra do Cabral, the other from Serra de Capanema and Serra do Cipó), in Minas Gerais state, a region known as a key area for Mimosa diversity. The description of more species sharing affinities with M. setosa var. paludosa indicates that the latter may be acting as a species pump.

First Time

We analyzed the advertisement calls of four species of Physalaemus (P. olfersii, P. moreirae, P. bokermanni, and P. jordanensis) from the Brazilian Atlantic Forest. The tadpole of P. olfersii is described for the first time. Calls of all species are composed by just one kind of note. Those of P. olfersii are long (4035 ms), pseudo-pulsed, with dominant frequency around 2375 Hz; 7–10 sidebands are well distinguishable. The calls of P. moreirae are pulsed, with duration about 604 ms, mean dominant frequency around 1369 Hz and 3–5 sidebands. Physalaemus bokermanni has a call structurally different from the other species by the absence of sidebands or harmonics, larger inter-pulse breaks (around 34–42 ms) and a wider frequency range (around 3700 Hz). Calls of P. jordanensis are pulsed and have 7–8 harmonics, last about 1068 ms and dominant frequency around 2742 Hz. Physalaemus olfersii tadpoles show typical features of other Physalaemus larvae, measuring about 19 mm in total length. Our data on call of P. olfersii suggest that a broader taxonomic survey would be worthwhile by revealing that different species are included under this name. Calls of P. moreirae and P. bokermanni, in general, are in agreement with those previously described from other sites, but complementary features are given. Those of Physalaemus jordanensis show some differences in relation to the calls from the type locality, but additional data are still necessary for a taxonomic conclusion.

Coffee Plantations

The use of green manure may contribute to reduce soil erosion and increase the soil organic matter content and N availability in coffee plantations in the Zona da Mata, State of Minas Gerais, in Southeastern Brazil. The potential of four legumes (A. pintoi, C. mucunoides, S. aterrimum and S. guianensis) to produce above-ground biomass, accumulate nutrients and mineralize N was studied in two coffee plantations of subsistence farmers under different climate conditions. The biomass production of C. mucunoides was influenced by the shade of the coffee plantation. C. mucunoides tended to mineralize more N than the other legumes due to the low polyphenol content and polyphenol/N ratio. In the first year, the crop establishment of A. pintoi in the area took longer than of the other legumes, resulting in lower biomass production and N2 fixation. In the long term, cellulose was the main factor controlling N mineralization. The biochemical characteristics, nutrient accumulation and biomass production of the legumes were greatly influenced by the altitude and position of the area relative to the sun.
