The distributions of 127 tree species, each with at least part of their range in the moist coastal forest of eastern Brazil, are analyzed. Of these, 53.5% are endemic to the coastal forest, 11.8% endemic to the coastal forest plus some part of the Planalto of Brazil, 7.8% disjunct with the Amazonian hylaea, and 26% widespread. This high endemism in the coastal forest of eastern Brazil, in view of its rapid destruction, emphasizes the need for increased preservation of the few remaining natural areas. In addition, this study supports the theory that there are at least two centers of endemism in the coastal forests, one centering around Rio de Janeiro and one in southern Bahia/Rio Doce, Espírito Santo. In order to protect the diverse flora of the coastal forests, preservation areas should be established intermittently along their entire length and especially in the centers of endemism. 相似文献

Biodiversity corridors comprise a mosaic of land uses connecting fragments of natural forest across a landscape. Two such corridors have been established along the eastern coast of Brazil: the Serra do Mar and the Central da Mata Atlantica corridors, along which most of the coastal plains are restinga areas. In this study, we analyze the present status of the endemic and endangered terrestrial vertebrates of both corridors. We sampled 10 restingas in both corridors, recording species of amphibians, reptiles, birds, and mammals. Some restingas harbor a relatively large number of endemic species,and two main regions of endemism can be identified along the restingas of both corridors: the coastal restingas from northern Espirito Santo State to southern Bahia State (between Linhares, ES, and Tarancoso, BA), and the coastal region between the restingas of Maricá and Jurubatiba, Rio de Janeiro State. Six species of terrestrial vertebrates considered threatened with extinction are found in the restingas of Serra do Mar and Central da Mata Atlantica biodiversity corridors (Liolaemus lutzae, Formicivora littoralis, Mimus gilvus, Schistochlamys melanopis, and Trinomys eliasi). The region located between the restinga of Maricá and that of Jurubatiba is of special relevance for the conservation of vertebrate species of the restingas of the corridors because a considerable number of threatened species of terrestrial vertebrates are found there. We strongly recommend efforts to develop checklists of threatened faunas for the States of Espirito Santo and Bahia. 相似文献

Aim To use the method of parsimony analysis of endemism to identify areas of endemism for passerine birds in the Atlantic Forest, South America, and to compare the locations of these areas with areas previously identified for birds as well as other taxa. Location The Atlantic Forest, eastern South America. Methods We analysed a matrix composed of the presence (1) or absence (0) of 140 endemic species in 24 quadrats of 1 × 1 degree distributed along the Atlantic Forest to find the most parsimonious area cladogram. Results Fourteen most parsimonious cladograms were found and then summarized in a single consensus tree. Four areas of endemism were identified: Pernambuco, Central Bahia, Coastal Bahia, and Serra do Mar. Main conclusions Avian areas of endemism in the Atlantic Forest have significant generality, as they are highly nonrandom and congruent with those of other groups of organisms. A first hypothesis about the historical relationships among the four areas of avian endemism in the Atlantic Forest is delineated. There is a basal dichotomy among areas of endemism in the Atlantic Forest, with Pernambuco forming a northern cluster and Coastal Bahia, Central Bahia and Serra do Mar comprising a southern cluster. Within the southern cluster, Central Bahia and Serra do Mar are more closely related to each other than to Coastal Bahia. 相似文献

The maned sloth Bradypus torquatus (Pilosa, Bradypodidae) is endemic to a small area in the Atlantic Forest of coastal Brazil. It has been listed as a threatened species because of its restricted geographic range, habitat loss and fragmentation, and declining populations. The major objectives of this study were to estimate its potential geographic distribution, the climatic conditions across its distributional range, and to identify suitable areas and potential species strongholds. We developed a model of habitat suitability for the maned sloth using two methods, Maxent and Mahalanobis Distance, based on 42 occurrence points. We evaluated environmental variable importance and the predictive ability of the generated distribution models. Our results suggest that the species distribution could be strongly influenced by environmental factors, mainly temperature seasonality. The modeled distribution of the maned sloth included known areas of occurrence in the Atlantic Forest (Sergipe, Bahia, Espírito Santo, and Rio de Janeiro), but did not match the observed distributional gaps in northern Rio de Janeiro, northern Espírito Santo or southern Bahia. Rather, the model showed that these areas are climatically suitable for the maned sloth, and thus suggests that factors other than climate might be responsible for the absence of species. Suitable areas for maned sloth were located mainly in the mountainous region of central Rio de Janeiro throughout Espírito Santo and to the coastal region of southern Bahia. We indicate 17 stronghold areas and recommended survey areas for the maned sloth. In addition, we highlight specific areas for conservation, including the current network protected areas. Our results can be applied for novel surveys and discovery of unknown populations, and help the selection of priority areas for management and conservation planning, especially of rare and relatively cryptic species directed associated with forested habitats. 相似文献

- 1 The endemic maned sloth Bradypus torquatus is globally threatened due to deforestation, habitat fragmentation and isolation of populations. Despite increased interest in the species in recent years, information on its geographic distribution is limited and is derived mainly from a few museum species and from a survey based mostly on interviews carried out more than 20 years ago. Information on its habitat and altitudinal preferences is lacking. We therefore compile, update and review all occurrence records of this species using geographical information system (GIS) tools and produce a distribution map for the species.
- 2 Our compilation totalled 188 occurrence records, of which 130 (69%) were considered confirmed (museum specimens or individuals captured or seen in the field), most of which (62%) were restricted to the states of Bahia and central‐south Espírito Santo (29%). The species occurs predominantly in ombrophilous forest (80%), from sea level to 1290m, but mainly (79%) below 200m altitude.
- 3 We used GIS techniques and the alpha shape algorithm to calculate the extent of occurrence of the species and compared the resulting map with distribution maps available in the literature. We found a great deal of variation in distribution area shape and an almost two‐fold variation in distribution area size among sources.
- 4 We confirmed the existence of a main distribution gap between southern Bahia and northern Espírito Santo and discovered a second smaller gap between southern Espírito Santo and northern Rio de Janeiro.
- 5 We also confirmed that B. torquatus is sympatric with the common three‐toed sloth Bradypus variegatus in a large part of the Atlantic forest and that the two species are syntopic in at least 11 locations.

Eschweilera tetrapetala Mori andE. alvimii Mori are described and compared withE. compressa (Vellozo) Miers, the only other species of this genus known to have four petals. It is concluded that this small group of species probably evolved from a common ancestor whose range was fragmented by climatic and vegetational changes in the Pleistocene. The distributions ofE. compressa andE. alvimii support the hypothesis that moist forest refuges existed around Rio de Janeiro and southern Bahia/northern Espírito Santo throughout the Pleistocene. 相似文献

Dichotomius schiffleri Vaz-de-Mello et al is often cited as endemic to the preserved coastal sandy-dune vegetation (restinga) of Guriri Island, Espírito Santo state, and is included in the Brazilian List of Endangered Fauna as "critically endangered" (CR). However, we recorded its occurrence in twelve additional sites along the coasts of Espírito Santo, Bahia, Sergipe and Pernambuco. The geographic distribution of D. schiffleri is limited to the coastal Atlantic Forest domain, mainly in preserved restinga patches. We recommend that D. schiffleri remains in the List of Endangered species, but in the "endangered" (EN) category, according to the IUCN criteria. 相似文献

We measured canine teeth from 28 woolly spider monkeys (Brachyteles arachnoides) to assess sexual dimorphism and population differences. The specimens are from the Brazilian states of Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, and São Paulo. We found strong sexual dimorphism in canine length for individuals belonging to populations south of 22°00 latitude but no sexual dimorphism in canine length from individuals of populations north of 21°00 latitude. Canine length did not vary among females of northern and southern populations. However, southern males had significantly longer canines than northern males. This geographical difference in canine morphology, together with the presence or absence of thumbs and published accounts of differences in genetics and social structure between northern and southern populations, suggests thatBrachyteles arachnoides may be composed of at least two subspecies, which appear to be separated by the rivers Grande and Paraiba do Sul and the Serra da Mantiqueira. 相似文献

Examination of 248 adult specimens of whitemouth croaker Micropogonias furnieri from five localities along the Brazilian coast revealed 8735 parasites belonging to 41 metazoan species. Samples from Ceará to Bahia and Rio de Janeiro to Santa Catarina showed a high level of correct assignation (92 and 87%, respectively) and cross assignation (i.e. almost all specimens misidentified in Ceará were assigned to Bahia and almost all specimens misidentified in Bahia were classified as Ceará), so samples were pooled in the northern and south‐eastern samples, and Rio Grande do Sul was considered a southern area. Eight parasite species were characteristic of the northern localities, five species were found just in the area associated with south‐eastern localities and two species were characteristic of the southern area providing first evidence of stock discreteness. The multivariate discriminant analysis successfully discriminated three groups of localities associated with three stocks of M. furnieri in Brazil: a northern stock associated with Ceará and Bahia, a south‐eastern stock related to Rio de Janeiro and Santa Catarina and a southern stock in the area of Rio Grande do Sul, which could be considered as the northern limit of the stock associated with the Common Fishing Zone of Uruguay and Argentina. 相似文献

Three new species of Galipea (Rutaceae, Galipeinae) are described and illustrated. Galipea carinata Pirani sp. nov. is known from the pluvial tropical forest in southern Espírito Santo State, eastern Brazil, and its main diagnostic features are the urceolate and conspicuously keeled calyx, the relatively short (14–16 mm) corolla tube, the long pedunculate, divaricate and loosely branched inflorescence, with few flowers crowded on tip of side branchlets, and the chartaceous leaflets, with lateral veins very prominent on both sides of the blade. Galipea revoluta Pirani sp. nov. is probably endemic to the coastal hygrophyllous Atlantic Forest in southern Bahia, eastern Brazil, and is very distinct by its mostly unifoliolate leaves, with a leathery, shiny lamina that is thickened and usually revolute at margin, by its calyx with large glands only at the base, and median nerve on each sepal. Galipea congestiflora Pirani sp. nov. is from forests on terra firme (non-inundated vegetation) of eastern Amazonia, most of them from the State of Pará, some others from eastern Maranhão and north of Tocantins. It is characterized mainly by 3-foliolate, chartaceous and dull leaves; a dense, corymbiform thyrsoid (partial inflorescences very short, crowded on top of the peduncle), which is smaller than the leaves; relatively large capsules (the largest in the genus) with an acute rim at the tip of each valve, and by the marmorate surface of the seeds. A brief discussion on the relationships of the new taxa to other species of Galipea is provided. © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 144, 365–373. 相似文献

The Espinhaço Range, located in the states of Minas Gerais andBahia, has a type of vegetation with one of the highest degrees of endemism inBrazil: the campos rupestres. In this area, Asclepiadoideaeis among the most diverse angiosperm groups, including species with broaddistributions and others restricted to small areas. This study attempts toevaluate the species richness and the degree of endemism in this region, as wellas the influence of collecting efforts on the perception of biodiversity. It isbased especially on the Asclepiadoideae from the Espinhaço Range of MinasGerais (ERMG), though a brief consideration of the situation in Bahia is alsointroduced. For comparative studies, the ERMG was divided into four regions:South, Serra do Cipó, Diamantina Plateau, and North. The species werethen characterized according to their distribution and occurrence in each ofthese regions. Ninety-seven species of Asclepiadoideae are native to the ERMG;about 30% of them are endemic to this area and almost 25% are restricted to onlyone of the four regions. The Serra do Cipó and the Diamantina Plateaupresent the highest degrees of endemism, and the highest richness innumber of species is found in the South. Nevertheless, there is a progressive decrease in collectingefforts northwards, which may distort species distribution and occurrence, andlead to misinterpretations about centers of diversity and endemism. TheEspinhaço Range should be considered vulnerable in its entirety becauseof the singular flora still incompletely known and the restricted distributionof many species. Programs that establish priority areas of conservation withoutconsidering the region as a whole will only offer temporary, partial protectionfor its biodiversity. 相似文献

We studied the amphibian community of the Private Reserve of Natural Heritage (RPPN) Serra Bonita, an area of 20 km2 with steep altitudinal gradients (200–950 m a.s.l.) located in the municipalities of Camacan and Pau-Brasil, southern Bahia State, Brazil. Data were obtained at 38 sampling sites (including ponds and transects within the forest and in streams), through active and visual and acoustic searches, pitfall traps, and opportunistic encounters. We recorded 80 amphibian species distributed in 15 families: Aromobatidae (1), Brachycephalidae (3), Bufonidae (4), Centrolenidae (2), Ceratophryidae (1), Craugastoridae (7), Eleutherodactylidae (2), Hemiphractidae (2), Hylidae (42), Hylodidae (1), Leptodactylidae (7), Microhylidae (3), Siphonopidae (1), Odontophrynidae (3) and Pipidae (1). Species richness was positively correlated with monthly rainfall. Near 36% of the species were found in strictly forest environments, 15% are endemic to Bahia State and 77.2% are endemic to the Atlantic Forest biome. The large species diversity of this small area, the high degree of endemism and the taxonomic and biogeographic significance turn the Serra Bonita mountain into a hotpoint for amphibians within Brazil’s Atlantic Forest hotspot. 相似文献

In this study, we analysed the processes resulting in the origin of two endemic sister species of bumblebees in the Brazilian Atlantic Forest. We studied the historical distribution pattern of Bombus bahiensis, which is restricted to small fragments in eastern Brazil and the phylogeographic pattern and historical demography of B. brasiliensis, which is widely distributed in southern and south-eastern Brazil and neighbouring regions of Uruguay, Paraguay, and Argentina. We used ecological niche models, niche analyses, and genetic and distribution data (i) to test the role of niche differentiation on the divergence between the two species, (ii) to find potential distribution areas for the most restricted B. bahiensis, and (iii) to evaluate the conservation status of both species. Our results showed that B. brasiliensis populations are able to disperse across mosaics of anthropogenic and preserved areas and exhibit low levels of spatial genetic structure. Otherwise, B. bahiensis presented a restricted distribution range and likely a lower diversity, where it is suffering with an increasing habitat loss. The climatic oscillations of the Pleistocene influenced the population structure of both species in different ways, probably due to differences in their effective population sizes, physiology and past demographic fluctuations. Specifically, while B. brasiliensis expanded its distribution range in the last 500,?000?years throughout most of the Atlantic Forest, B. bahiensis remained restricted to a small rainforest area between southern Bahia and northern Espírito Santo states in Brazil. In its southern distribution, in the state of Espírito Santo, B. bahiensis is currently very rare or extinct. Currently, the adjacent ranges of Bombus brasiliensis and B. bahiensis do not overlap and our results indicate that these species may have further diversified through a reinforcement process associated to niche specialization and differentiation. 相似文献

Nests of Synoeca septentrionalis were collected in two Brazilian Atlantic Rain Forest localities (Itabuna and Santa Terezinha, in the state of Bahia and Alfredo Chaves in the state of Espírito Santo). Synoeca septentrionalis was previously recorded only from Central America and northwestern South America. This findingextends its geographical distribution to Northeast and Southeast regions of Brazil, and represents the first record for Synoeca septentrionalis in the Brazilian Atlantic Rain forest, raising to three the number of Synoeca species known from Bahia State. 相似文献

Most studies of the sand fly fauna in southeastern Brazil are conducted in the peridomiciliary environment of leishmaniasis endemic regions. Therefore, to increase the knowledge about diversity and richness of sand fly conservation areas, we describe here the sand fly fauna from the National Forest of Goytacazes (NFG), state of Espírito Santo, Brazil, and its surroundings areas. We also used sand fly fauna records from eight conservations units within the state of Espírito Santo to understand the similarity and relationships among them. The sand flies were simultaneously collected from June, 2008 to May, 2009 in two different environments: a preserved environment represented by the NFG and a modified environment represented by a peridomicile. To establish the similarity among the conservation units, we used a method very similar to parsimony analysis of endemism. We collected 2,466 sand fly specimens belonging to 13 species. Pressatia choti and Nyssomyia intermedia were the most abundant sand fly species. Ny. intermedia is a known vector of Leishmania braziliensis and epidemiological surveillance must be conducted in the area. We discuss aspects regarding the diversity of sand flies as well as the risk of transmission of Leishmania parasites in the area. We also provide for the first time a hypothesis of similarity relationships among conservation units within the state of Espírito Santo. 相似文献

Knowledge of species richness centers is necessary for the design of conservation areas. In this study, we present a GIS analysis
of two years of field data on animal and plant diversity distributions in evergreen, coastal rain forests of southern Chile
(39°30′–41°25′ S). Despite their high endemism, these forests have remained largely unprotected. Field records were complemented
with data from museum collections and scientific literature. We used selected environmental variables (evapotranspiration,
altitude) and, in some cases, forest types as predictors of species distributions. Our study focused on the distribution of
forest bryophytes, vascular plants, soil invertebrates, amphibians and birds. We generated distributional maps for each taxa
based on their field records in the study area, complemented by natural history information, except in the case of bryophytes
and soil invertebrates. In general, species richness was lower at 600 m elevation or above for all the taxa studied. Species
richness tends to increase in the northern sector of the study area. We observed a greater richness of vascular plants near
rivers and streams, and noted important floristic differences between west and east-facing slopes of the Coastal Range, with
more species in the oriental side. Because species in high altitude forests are not a subset of those found at lower elevations,
we propose that conservation strategies should prioritize the protection of the entire altitudinal gradient of the southern
Coastal Range, especially in the more diverse oriental and northern sectors. 相似文献

The Espinhaço Range, a mountain chain located in the Brazilian states of Minas Gerais and Bahia, contains one of the richest floras in Brazil, with a high frequency of endemic species. Since 2005 it is designated as UNESCO biosphere reserve and is situated at the joint border of two global hotspots for biodiversity conservation. Endemic species with congruent occurrence patterns were identified in order to establish areas of higher endemism within the Espinhaço Range. Taxonomic reviews were analyzed in order to identify endemic taxa and a dataset was elaborated containing 1765 records from 178 endemic species of vascular plants, representing 17 families and including the geographic coordinates for each record. Two maps were produced showing species richness and collection effort in 15′ quadrats. The congruent occurrences were identified and a third map was provided, delimiting 10 candidate areas of endemism for a “parsimony analysis of endemicity” (PAE). One most parsimonious cladogram is then retrieved, evidencing three major clades corresponding to the northern, central and southern portions of the Espinhaço, in addition to four subclades included into the central clade. We finally identified six major areas of endemism. Furthermore, there is a strong correlation between species richness and collector effort, revealing which areas are in need of further field inventories. 相似文献

Coastal forests of eastern Africa: status, endemism patterns and their potential causes 总被引:3,自引:0,他引:3

Eastern African coastal forests are located within the Swahili regional centre of endemism and Swahili-Maputaland regional transition zone in eastern Africa, between 1d? North and 25d? South, and 34—41d? East. Approximately 3167 km2 coastal forest remains: 2 km2 in Somalia, 660 km2 in Kenya, 697 km2 in Tanzania, 16 km2 in Malawi, 3 km2 in Zimbabwe and perhaps 1790 km2 in Mozambique. Most forests are small (≤ 20 km2), and all but 19 are under 30 km2 in area. Over 80% of coastal forest is located on government land, principally Forest Reserves; only 8.3 km2 is found in National Parks (6.2 km2 in Kenya (Arabuko-Sokoke), 2 km2 in Tanzania (Mafia Island) and tiny patches in Zimbabwe). Coastal forests are an important and highly threatened centre of endemism for plants (c 550 endemic species), mammals (6 species), birds (9 species), reptiles (26 species), frogs (2 species), butterflies (79 species), snails (>86 species) and millipedes (>20 species). Endemic species are concentrated in the forests of the Tana River, between Malindi in Kenya to Tanga in northern Tanzania, and in southern Tanzania. Forests with highest numbers of endemics are: lower Tana River, Arabuko-Sokoke, Shimba Hills (Kenya); lowland East Usambara, Pugu Hills, Matumbi Hills, Rondo and Litipo and other plateaux near Lindi (Tanzania); the Tanzanian offshore island of Pemba; Bazaruto archipelago (Mozambique), and tiny forest remnants of southern Malawi, eastern Zimbabwe and Mozambique. Most coastal forest endemics have a narrow distributional range, often exhibiting single-site endemism or with scattered or disjunct distributional patterns. They are best interpreted as relicts and not the result of recent evolution. Relictualization probably started with the separation of the ancient Pan African rainforest into two parts during the Miocene. The coastal forests are interpreted as a ‘vanishing refuge’ with the endemic species gradually becoming more and more relict (and presumably extinct) due historically to climatic desiccation and more recently to human destruction. 相似文献

Melipona capixaba, popularly known as “uruçu preta”, is a stingless bee restricted to the mountainous Atlantic Rainforest areas of Espírito Santo State, Brazil. Due to the endemism and small population size, this species discovered in 1994 is now considered “vulnerable to extinction”. Using ISSR, PCR–RFLP and microsatellites markers, we studied the genetic variability and structure of M. capixaba from 88 colonies collected throughout the distribution area of the species within Espírito Santo State. The microsatellite, ISSR and mitochondrial haplotype analyses showed that M. capixaba has low genetic variability compared to other insect species. The molecular analyses also indicated a high genetic similarity among the M. capixaba samples, with no clear pattern of structuring. The analyses of molecular variance results indicated that most of the total genetic variation in M. capixaba was explained by the genetic diversity within local populations. Results suggest that the analyzed samples could be treated as a single population for preservation purposes. Thus, given its endemism, local adaptation and low number of natural colonies, efforts for the conservation of M. capixaba should focus on preservation and increasing the number of colonies in the wild, so that M. capixaba can support constant captures and the effects of habitat deforestation in Espírito Santo State. 相似文献
