Synopsis of Poaceae in the grassland formations of the Parque Estadual do Guartelá, Paraná State, Brazil

Abstract

Poaceae is a cosmopolitan family that includes species found in both forest and grassland formations. The objective of this study was to carry out the first floristic survey of Poaceae in the Parque Estadual do Guartelá (PEG), one of the last remnants of native grassland vegetation in the State of Paraná, Brazil, and provide resources to assist the identification of genera and species. The survey was conducted based on field collections and searches in the Species Link online database. In the PEG, Poaceae is represented by 29 genera and 54 species, being Paspalum L. (eight spp.), Andropogon L. (five spp.) and Eragrostis Wolf (four spp.) the richest genera. The number of species in the PEG was incremented by 29 new records. In addition, five species were classified as exotic, five as endemic to Brazil, and two were considered least concern in relation to their conservation. We also present information regarding the distribution, habitat and conservation status for each species.

A new species of Proceratophrys Miranda-Ribeiro, 1920 (Anura, Odontophrynidae) of the P. bigibbosa species group from Southern Brazil

“…Grassland physiognomies (e.g., rocky vegetational refuge, hygrophilous steppe, and grassy-woody steppe) are predominant in this region (Fig. 8), consisting of relictual vegetation that include Mixed Ombrophilous Forest and Cerrado mosaics (Carmo et al 2012;Souza et al 2018). Calling males and a female were found in temporary puddles and slow running waters associated to flooded grasslands in the Private Reserve of Natural Heritage (RPPN Rancho Table 1.…”

“…In the Tibagi area, the Guartelá Canyon region is a landscape of the Campos Gerais corresponding to the second plateau of Paraná state. The native landscape is characterized as a vegetational relict associated to southern grasslands (Campos Sulinos), Araucaria Forest (Floresta Ombrófila Mista), and Tropical savannah (Cerrado) (Carmo et al 2012;da Maia and Goldenberg 2014;Souza et al 2018). At least two other species occur in this region, Melanophryniscus vilavelhensis and Scinax rossaferesae, with distributions strongly associated to the region (Crivellari et al 2014;Conte et al 2016).…”
