A dark scenario for Cerrado plant species: Effects of future climate, land use and protected areas ineffectiveness

Diversity and Distributions, Journal Year: 2019, Volume and Issue: 25(4), P. 660 - 673

Abstract Aim The anthropogenic climate change and land use are considered two of the main factors that altering biodiversity at global scale. An evaluation combined both can be relevant to detect which species could most vulnerable reveal regions highest stability or susceptibility biodiversity. We aimed to: (a) assess effect on distribution Cerrado plant for different countries where they occur, (b) evaluate effectiveness current network protected areas (PAs) safeguards under greenhouse–gas (GHG) emissions scenarios, (c) estimate vulnerability based protection habitat loss. Location Bolivia, Brazil Paraguay. Methods modelled 1,553 evaluated range loss caused by present future GHG 2050 2080. assessed combining representativeness within conservation units with species’ ranges outside PAs. Results found will cause great damage flora 2080, even optimistic conditions. greatest impacts occur in richness harboured. seriously affected since PA is not as effective safeguarding them Main conclusions low level together losses advance agricultural lands lead being highly vulnerable. Due distinct over three countries, strategies should implemented transboundary national levels.

The underestimated biodiversity of tropical grassy biomes

For decades, there has been enormous scientific interest in tropical savannahs and grasslands, fuelled by the recognition that they are a dynamic potentially unstable biome, requiring periodic disturbance for their maintenance. However, not translated into widespread appreciation of, concern about threats to, biodiversity. In terms of biodiversity, grassy biomes considered poor cousins other dominant biome tropics—forests. Simple notions being species-poor cannot be supported; some key taxa, such as vascular plants, this may valid, but others it is not. Here, we use an analysis existing data to demonstrate high-rainfall (TGBs) have vertebrate species richness comparable with forests, despite having lower plant diversity. The Neotropics stand out both overall number range-restricted TGBs. Given high rates land-cover conversion Neotropical biomes, should priority conservation greater inclusion protected areas. Fire needs actively maintained these systems, many cases re-introduced after decades inappropriate fire exclusion. relative intactness TGBs Africa Australia make them least vulnerable biodiversity loss immediate future.

Protected areas: A focus on Brazilian freshwater biodiversity

Diversity and Distributions, Journal Year: 2018, Volume and Issue: 25(3), P. 442 - 448

Published: Nov. 17, 2018

Abstract Brazil has a variety of aquatic ecosystems and rich freshwater biodiversity, but these components have been constantly damaged by the expansion unsustainable activities. An array different conservation strategies is needed, especially creation protected areas (PAs, hereafter). However, Brazil's PAs are biased towards terrestrial we argue that current limited efficacy in protection biodiversity. New should better consider environments, covering entire basins, rivers other habitats. We recommend ways to implement provide guidance avoid social impacts. Freshwater systems essential goods services being rapidly degraded will be lost if not adequately protected.

Woody encroachment and its consequences on hydrological processes in the savannah

Woody encroachment due to changes in climate or the disturbance regimes (fire and herbivory) has been observed throughout savannah biome over last century with ecological, hydrological socioeconomic consequences. We assessed tree density basal area estimated rain interception by canopies across a 5-year period biomass gradient Cerrado vegetation protected from fire. modelled throughfall, stemflow net rainfall on basis of (TBA).

Classification of South Brazilian grasslands: Implications for conservation

Applied Vegetation Science, Journal Year: 2018, Volume and Issue: 22(1), P. 168 - 184

Published: Nov. 17, 2018

Abstract Aims We offer a first classification of South Brazilian grasslands ( Campos Sulinos ) based on quantitative vegetation data and describing grassland types in terms dominant indicator species. Location (Paraná, Santa Catarina, Rio Grande do Sul states). Methods described plots 167 sampling units throughout the region using stratified nested design, totalizing 1,502 1 m² quadrats. classified cluster analysis Bray–Curtis dissimilarities, establishing three ten subtypes. conducted species within resulting subtypes, for all possible combinations Results In analyses, clear separation poorly drained from drier sites appeared. Further, distinction between highland region, situated Atlantic Forest biome, Pampa to south, emerged, reflecting climatic management differences. Highland showed lower cover dominance, while Pampa, Paspalum notatum clearly was most important abundance exotic higher. Conclusions Our study provides recorded standardized design. The support division into main phytogeographic (Brazilian biome classification). Grasslands these two regions also differ dominance pattern (higher grasslands, likely due higher grazing levels) conservation state (low presence grasslands). results are policies, which can now consider different but more will be necessary detailed that considers abiotic features detail.
