Such information is needed for effective conservation planning and management of forests and woodlands, including monitoring of amphibian populations in a period of apparent global decline. Amphibian surveys can be time-consuming and expensive, and many issues must be addressed to maximize the reliability of the resulting data. Sampling techniques that are effective in one region or habitat type may be less so in another, and a preliminary study comparing different techniques before undertaking a survey may be necessary. Data collected in poorly designed surveys can be unsuitable for statistical analysis, and may sometimes present a misleading picture of the distribution, abundance and habitat requirements of amphibian species. This review examines issues of survey design, assesses past amphibian surveys in forest and woodland habitats, and provides recommendations for planning an amphibian survey. Firstly, the study area and survey aims should be identifi ed, and proposed sampling techniques assessed using relevant literature or a pilot study. Ethical issues associated with proposed sampling techniques should also be considered. The number, size and arrangement of the survey units (e.g. plots, sites or transects) should be sufficient to address the survey aims. The survey units should be systematically surveyed several times with appropriate sampling techniques.","PeriodicalId":173367,"journal":{"name":"Contemporary Herpetology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117131736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advertisement, courtship, territorial, encounter, reciprocation, release and distress calls are main kinds of anuran vocalizations (Duellman and Trueb 1994; Gerhardt and Huber 2002). Besides advertisement call, some species of Leptodactylus of the L. pentadactylus group (sensu Heyer 1979, 2005) present reciprocation, release and distress calls (Heyer 1979; Hödl and Gollmann 1986; Hero and Galatti 1990; Kaiser 1994; Davis et al. 2000; Heyer and Thompson 2000; Heyer 2005; Toledo et al. 2005). The vocal repertory of L. labyrinthicus includes advertisement, courtship, distress, and territorial calls (Márquez et al. 1995; Toledo et al. 2005; Zina and Haddad 2005).

Herein we describe fi ve new types of vocalizations for two foam-nesting species of the Leptodactylus pentadactylus group, L. syphax and L. labyrinthicus. Behavioral observations and recordings were done in four localities within the Cerrado biome, at southeast and central Brazil. Before emitting advertisement calls, males of L. syphax often started producing a sequence of notes, which gradually turned into the advertisement call. These different notes may be an introductory call, which would serve to prepare the vocal structures for the emission of the high-frequency/amplitude advertisement calls. A male of L. syphax was emitting advertisement calls when a female approached and started to emit brief and low-amplitude calls; these vocalizations probably are reciprocation calls. Males of L. labyrinthicus involved in agonistic interactions can emit vocal cracks (encounter call) and deep rough sounds (territorial calls). Five courting males of L. labyrinthicus released screams with their mouth slightly opened in response to the approach of human observers. We conclude that these screams do not represent distress or territorial calls.","PeriodicalId":173367,"journal":{"name":"Contemporary Herpetology","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115830437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many early observations from Kentucky, Tennessee, Virginia, and West Virginia report A. aeneus taken from woody and arboreal habitats. There have been only four published records of A. aeneus using such habitats within the Blue Ridge Disjunct population of southwest North Carolina, northeast Georgia, and northwest South Carolina, and no records since 1952. Here I report two personal observations of A. aeneus using arboreal habitats in North Carolina. Additionally, I report nine observations, made by others, of A. aeneus using woody, arboreal, or otherwise non-rock-crevice habitats in North and South Carolina, including the first non-rock-crevice A. aeneus nesting record for the Blue Ridge. I also speculate that woody and arboreal habitats play a much larger role in the life-history of A. aeneus than generally thought, and that the rarity of A. aeneus is linked to the loss of American Chestnut and old-growth forests. INTRODUCTION AND METHODS The green salamander (Aneides aeneus) is distributed from central Alabama to southwestern Pennsylvania along the Appalachian Plateau (Petranka, 1998). A separate and smaller cluster of populations, the “Blue Ridge Disjunct”, occurs in the mountains of southwest North Carolina, northeast Georgia, and northwest South Carolina (Bruce, 1968; Petranka, 1998). The green salamander is the only representative of the genus Aneides, or “Climbing Salamanders”, in the eastern United States and is generally uncommon across its range due to specialized habitat requirements (Petranka, 1998). Aneides aeneus is almost exclusively observed inhabiting rock crevices of outcrops, which are located within associations of the mixed-mesophytic forest (Gordon, 1952; Corser, 1991; Petranka, 1998). However, early observations from Kentucky, Tennessee, Virginia, and West Virginia report A. aeneus breeding and foraging within woody and arboreal habitats (Gordon, 1952). Pope (1928) and Barbour (1949) report A. aeneus being taken almost exclusively from beneath the exfoliating bark of standing or fallen, yet “solid”, dead trees, mostly American Chestnut (Castanea dentata). Fowler (1947) reports A. aeneus being found under the bark of a fallen American Chestnut tree. Barbour (1949) reports one A. aeneus within the cavity of a standing dead American Chestnut and a brooding female beneath the bark of a fallen tree. Pope (1928) reports one individual within a rotted log and a brooding female within the small cavity of a prostrate limb of an Oak (Quercus spp.) tree. Welter and Barbour (1940) and Canterbury (1991) also report observations of A. aeneus beneath the loose bark of dead trees or within rotted stumps. In contrast with these widespread observations of the use of arboreal habitats and woody debris by A. aeneus in the main range populations, there are only four published records of A. aeneus individuals observed in habitats other than r","PeriodicalId":173367,"journal":{"name":"Contemporary Herpetology","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131662406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Augustine","doi":"10.17161/ch.vi1.11966","DOIUrl":"https://doi.org/10.17161/ch.vi1.11966","url":null,"abstract":"We investigated the relationship between arboreal frogs, tank bromeliads and landscape transformation in tropical forests of southeastern Campeche, Mexico. We surveyed frogs in six distinct habitats: slash and burn agriculture, seasonally flooded forest (bajo), aquatic habitats (lagoons and small ponds), second growth upland forest, primary forest and creek habitat using both systematic and non-systematic surveys. The highest species richness of frogs was documented in primary forest and small ponds. In contrast, no frogs were recorded in second growth forest. Similarly, tank bromeliads (Aechmea bracteata) were completely absent from early successional stages and were almost twice as abundant in seasonally flooded forest as in upland forest. The vertical distribution of A. bracteata differed between forest types, and they significantly more abundant in larger diameter trees. We examined 60 tank bromeliads during the peak of the dry season to test their use as refugia by frogs. Approximately 27% of tank bromeliads sampled had arboreal frogs belonging to three species, but 9 species have been recorded as occasional users of bromeliads in the region. There were significantly more frogs on large than on medium-sized bromeliads, and frogs were more abundant on bromeliads higher on host trees, particularly those above 3 m in height. Our results suggest that the loss of tank bromeliads from drier and less structurally complex habitats created by slash and burn agriculture and selective logging results in loss of refugia for arboreal frogs in this seasonal tropical forest. We suggest that Aechmea bracteata be a keystone species in seasonal tropical forest.

Hicimos muestreos de ranas en seis hábitats distintos: agricultura de roza, tumba y quema, selvas inundables (bajos), hábitats acuáticos (laguna, estanque pequeño), selva perturbada, selva primaria y hábitat ribereño utilizando métodos sistemáticos y no sistemáticos. Encontramos la mayor riqueza de especies de ranas en bosque primario y en el pequeño estanque. Por el contrario, no registramos ranas en selva secundaria. De igual manera, no registramos ninguna bromelia de tanque (Aechmea bracteata) en etapas sucesionales tempranas. Hubo casi el doble de bromelias en selvas inundables que en selvas no inundables. La distribución vertical de A. bracteata cambia en diferentes tipos de selvas y son más abundantes en árboles con diámetros mayores. Examinamos 60 bromelias de tanque para probar su utilización como refugio de ranas. Durante la época mas seca 27% de las bromelias de tanque muestreadas tuvieron ranas arbóreas.
