Birds in the genus Cinclodes are habitat specialists, with most restricted to the highlands of South America. The recently described Cipo Cinclodes (C. espinhacensis) is isolated in the southern Espinhaço Range of Brazil and is considered Endangered in Brazil and Near Threatened by the IUCN, but as a subspecies of Long‐tailed Cinclodes (C. pabsti). We examined the population and spatial ecology of Cipo Cinclodes at two geographic scales to improve our understanding of their basic biology and conservation status. We monitored 30 birds at Serra do Breu and found relatively large home ranges (mean = 9.3 ha), a density of paired adults of 0.09/ha, a male‐skewed adult sex ratio (males/total adults = 0.57) due to territories occupied by unpaired males, and long‐term site fidelity. Cipo Cinclodes used all habitat types available in our study area, including rocky outcrops, grasslands, and riparian areas, but habitat selection analyses revealed the importance of riparian areas for foraging and rocky outcrops for nesting. At the species distribution scale, we compiled known and novel recorded occurrence points and used them to calculate the extent of occurrence (EOO) and the area of occupancy (AOO). We used a Maxent species distribution model to generate a binary map to estimate upper limits for EOO (EOO around the model predicted area) and AOO (comprised by the model predicted area within the EOO). We obtained 41 locations, resulting in an EOO of 890.7 km2 (up to 1748.7 km2) and an AOO of 100 km2 (up to 327.5 km2). The global population is estimated to be between 880 and 2882 birds, which is concerning because small populations are at risk of extinction due to demographic stochasticity, genetic drift, and the interaction of these factors. As such, our results support the designation of Cipo Cinclodes as Endangered on the Brazilian red list.

“…Tal medida propiciaria o retorno do ecossistema a uma dinâmica consistente com a necessidade de conservação da fisionomia campestre (Alves e Silva, 2011; Ribei- ro e Figueira, 2011). Isso evidencia o grande dilema dos impactos provocados pelo fogo: por um lado, a exclusão completa do fogo coloca em risco a vegetação campestre como um todo, em detrimento das espécies com porte arbóreo (Moreira, 2000;Veldman et al, 2015;Durigan e Ratter, 2016;Honda e Durigan, 2016), por outro lado, um aumento na frequência de incêndios poderá afetar de maneira relevante mesmo as populações de vegetações primariamente campestres (Arkle e Pilliod, 2010;Neves et al, 2011;van Wilgen, 2013;Aximoff et al, 2016;Figueira et al, 2016).…”

“…Nesse contexto, o presente estudo teve como objetivo a avaliação da resiliência ao fogo em Coccoloba cereifera Schwacke (Polygonaceae), uma espécie arbustiva ameaçada de extinção (Guimarães et al, 2014) e endêmica dos campos rupestres (Melo, 2009). Esse arbusto ocorre em um ecossistema tropical extremamente infértil, com baixa resiliência a distúr-bios no solo Silveira et al, 2016) e sujeito a um regime de queimadas que vem aumentando a frequência nas últimas décadas (Figueira et al, 2016). Especificamente, avaliamos a capacidade de rebrotamento pós-fogo de C. cereifera, e comparamos plantas de populações queimadas e não queimadas em relação à taxa de crescimento e ao investimento reprodutivo.…”

ResumoEmbora existam evidências de que a vegetação dos campos rupestres seja resiliente à passagem do fogo, são incipientes as investigações sobre os efeitos da crescente frequência de incêndios de origem antrópica em plantas raras e endêmicas desse ecossistema. Neste estudo, monitoramos o rebrotamento pós-fogo da espécie Coccoloba cereifera Schwacke (Polygonaceae), um arbusto ameaçado e endêmico dos campos rupestres do sudeste do Brasil. Cinco meses após o incêndio, rebrotaram 100% dos indivíduos monitorados. Entretanto, um ano após o incêndio, as plantas queimadas ainda apresentaram comprimento da rameta 24% inferior e número de folhas 53,5% inferior em relação ao porte das plantas não queimadas. As plantas queimadas apresentaram taxa de crescimento relativo em número de folhas muito superior e investimento reprodutivo muito inferior em comparação com as plantas não queimadas. Embora a espécie estudada demonstre alta capacidade de rebrotamento pós-fogo, o padrão de crescimento vegetativo e investimento reprodutivo apresentado pelas plantas rebrotadas indica que a crescente frequência de incêndios antrópicos represente uma séria ameaça para C. cereifera.

AbstractAlthough there is evidence that the vegetation from rupestrian grasslands is resilient to fire, investigations about the effects of increasing frequency of anthropogenic fires in the rare and endemic plants from this ecosystem are still incipient. In this study, we monitored the post-fire resprouting of the endemic and endangered shrub species Coccoloba cereifera Schwacke (Polygonaceae) from rupestrian grasslands, southeastern Brazil. Five months after the fire 100% of the monitored individuals resprouted. However, one year after the fire, the burned plants had the ramet length 24% lower and number of leaves 53.5% smaller in relation to unburned plants. Burned plants showed a much higher relative growth rate in number of leaves and much lower reproductive investment compared to unburned plants. Although the studied species showed a high ability to resprout after fire, the pattern of vegetative growth and reproductive investment showed by the burned plants suggested that the increasing frequency of anthropogenic fires represents a serious threat to C. cereifera.

“…Periandra mediterranea exhibited high biomass allocation to the shoot, which also occurs with other native species of shallow and stony soil environments, in which root growth is difficult (Negreiros et al 2009). Nevertheless, under natural conditions the species is fairly capable of re-growing after burning (Hoffmann & Solbrig 2003;Neves & Conceição 2010;Figueira et al 2016). This feature is particularly relevant for revegetation of degraded areas of rupestrian grasslands, in which fires are common (Figueira et al 2016).…”

Growing Periandra mediterranea on post-mining substrate: native Fabaceae with potential for revegetation of degraded rupestrian grasslands in Brazil

et al. 2018

Recovery of degraded areas of rupestrian grasslands is hampered mainly by the limited knowledge regarding substrate management and the biology of native species suitable for revegetation of these areas. Th e aim of our study was to examine the establishment and growth of Periandra mediterranea in diff erent textures of lateritic substrate from a mining-degraded area. Th e growth of P. mediterranea was evaluated using fi ne and coarse laterite, both with and without the addition of topsoil. Survival, dry biomass, content of chemical elements and nodulation were evaluated in ten individuals per treatment sixteen months after planting. Although the substrate has low nutrient content, yet high metal concentrations, all plants survived. Plants growing on coarse laterite had 140 % greater biomass than those growing on fi ne laterite. Th e addition of topsoil increased biomass in coarse and fi ne laterite by 46 and 151 %, respectively, and doubled the number of nodulated plants, regardless of grain size. Th e biomass accumulation of P. mediterranea to a dystrophic substrate revealed its potential for use in the revegetation of degraded areas of rupestrian grasslands. Furthermore, the addition of topsoil facilitated the association of P. mediterranea with nitrogen-fi xing bacteria, and increased its growth and capacity to improve substrate fertility.
