“…). Today, in the mountainous areas of the Nordeste, Ficus calyptroceras and F. guianensis are the most frequent species (Andrade et al ., ; Ferraz & Rodal, ; Araújo et al ., ; Costa‐Junior et al ., ; Lima et al ., ). Ficus , represented mostly by entomophilous trees with generally low pollen dispersion, probably grew near the coring site.…”

“…). Based on botanical inventories carried out in mountainous areas in the Nordeste (Andrade et al ., ; Ferraz & Rodal, ; Araújo et al ., ; Costa‐Junior et al ., ; Lima et al ., ), the Moraceae–Urticaceae‐type is represented by several genera ( Artocarpus , Brosimum , Clarisia , Helicostylis , Pourouma , Sorocea , Urera ). In the mountainous areas of the Nordeste, most of the trees included in these genera are associated with dense ombrophilous forests, as has been observed in the Atlantic and Amazonian rain forests (Rolim et al ., ; Ferraz et al ., ).…”

Aim The primary objectives of this study were (1) to assess, in the light of palaeoecological reconstruction, the climate stability hypothesis used by evolutionary biologists to explain high diversity in historically stable areas, and (2) to identify the response mechanisms of a tropical rain forest microrefugium to climatic variability. Location North-eastern Brazil, Serra de Maranguape. Methods Vegetation and climatic changes were reconstructed using a pollen record in a sediment core from a forest hollow, and the chronology was based on accelerator mass spectrometry radiocarbon analyses. Results Past vegetation dynamics consisted of three main forest types, shown by major compositional changes in rain forest assemblages between 5000 and 1000 cal. yr bp. Dense ombrophilous forest was abruptly replaced by heliophilous early successional tree taxa at 4275 cal. yr bp. These early successional tree taxa were established over a period of c. 100 years, and their dominance lasted for c. 750 years and was associated with dry conditions until 3525 cal. yr bp. Subsequently, the expansion of secondary successional tree taxa over a period of c. 550 years enabled the recovery of ombrophilous forest. Main conclusions The vegetation changes in the Serra de Maranguape provide evidence for the high sensitivity of this rain forest microrefugium to climatic variability on a multidecadal to millennial time-scale during the mid- to late Holocene. Despite the substantial compositional and climatic changes, this microrefugium apparently was continuously forested and responded to climatic instability by recruiting key species to its highly diverse stock. This evidence helps to address the joint concerns of evolutionary biologists and palaeoecologists regarding how forests can persist during periods of climatic variability by showing that some tropical regions can remain continuously forested despite reorganization during abrupt and short-term climatic changes.

ResumoEsse artigo apresenta uma revisão dos tipos vegetacionais do estado do Ceará a partir de sua diversidade paisagística, centrando-se, notadamente, nas condições climáticas e unidades geomorfológicas. Com base em levantamentos de campo, literatura especializada e mapas das unidades fitoecológicas e geomorfológicas, pretendemos expor, de forma didática, a caracterização, distribuição e principais ameaças antrópicas concernentes a cada vegetação. Por fim, utilizamos métodos de análise multivariada para comparar a similaridade de espécies entre os diferentes levantamentos florísticos disponíveis para o estado e discutimos os padrões biogeográficos observados.

“…Neolentinus cirrhosus was collected near a water reservoir at the locality called Juá dos Vieiras, Viçosa do Ceará Municipality, Ceará State, Northeast Brazil. The region comprises the 'Área de Proteção Ambiental (APA) Planalto da Ibiapaba' federal reserve and comprises mostly carrasco, a tall-shrubby vegetation that is relatively closed and xerophilous, with a high density of woody plants, especially small trees (3-4 m high) with thin trunks (Araújo & Martins 1999;Lima et al 2011).…”

Neolentinus is a brown-rot genus (order Gloeophyllales) rarely found in the Neotropics. The only known species in the region is N. cyatiformis, reported from Argentina. This paper reports the discovery of a second species of Neolentinus in the Neotropics: N. cirrhosus. The species has a set of unique characteristics: lentinoid habit, squamulose pileus with ciliate/pilose margin, decurrent lamellae, small basidiospore size, and habitat on sand, with soil-incrusted sclerotium. The species is described, illustrated and discussed.
