Scale-dependent shifts in functional and phylogenetic structure of Mediterranean island plant communities over two centuries
Chunhui Zhang, Marc William Cadotte, Alessandro Chiarucci, Michel Loreau, Charles Willis, Xingfeng Si, Lanping Li & Marcus Cianciaruso
1. Since the Industrial Revolution, the rapid global population and economic expansion has had tremendous impacts on biodiversity across spatial scales, especially for islands. While changes in species richness are easily inferred, the impact of human activity on the underlying community assembly processes has been difficult to ascertain because of lack of long-term community data. 2. Here, we document how the manifestations of plant community assembly have changed over time and space in a Mediterranean...
Acaulescence promotes speciation and shapes the distribution patterns of palms in Neotropical seasonally dry habitats
Cibele Cássia-Silva, Rafael Silva Oliveira, Lílian P. Sales, Cíntia G. Freitas, Lucas Jardim, Thaíse Emilio, Christine D. Bacon & Rosane G. Collevatti
Rainforests have been a source of lineages to open and seasonally dry habitats throughout Angiosperm evolution, especially in the Neotropics. However, the underlying mechanisms that allow such shifts remain poorly understood at large spatial scales. Here, we test whether acaulescence (an underground stem or a very short stem concealed in the ground) has affected the colonization and speciation in Neotropical seasonally dry habitats by cocosoid palms (Cocoseae). Acaulescent species maintain their growth underground, which increases...
Landscape structure and local variables affect plant community
Juliana Silveira Dos Santos, Carlos M. Silva-Neto, Thiago Castro Silva, Karoline Nascimento Siqueira, Milton Cezar Ribeiro & Rosane Collevatti
The biodiversity in agricultural landscapes depends on land-use types, natural elements, and farming intensity. The Brazilian Cerrado is a biodiversity hotspot, however, the native vegetation loss rates have increased in the last years, leading several plant species to extinction risk. Here, we analyze the effects of local (soil fertility and litter amount) and landscape variables (patch shape, habitat amount, compositional heterogeneity, matrix dominance and connectivity) on alpha species richness and diversity, and basal area of...
Temporal changes in the potential geographic distribution of Histiotus velatus (Chiroptera, Vespertilionidae), the “decade effect\"
Liriann Chrisley Da Silva, Rafaela Almeida, Pablo Henrique Da Silva, Monik Oprea, Poliana Mendes, Daniel Brito & Thiago Vieira
Also investigate how the potential distribution of this species changes with the addition of new records over the decades (decade effect). Assuming that (1: hypothesis of the effect of the decade) the addition of new occurrence records over time increases the potential size of the species distribution; and (2: Wallacean distance hypothesis) over the years, the new points added are increasingly distant from the research centers. Considering the geographic knowledge gap of Histiotu velatus, our...
Quantitative genetics of extreme insular dwarfing: the case of red deer (Cervus elaphus) on Jersey
José Alexandre Felizola Diniz-Filho, Ana Santos, Elisa Barreto, Felipe Naves, Wanderson Santos, Kelly Souza, Rejane Santos-Silva, Ricardo Dobrovolski, Thannya Soares, Rosana Tidon, Zander Spigoloni, Thiago Rangel, Pasquale Raia, Joaquín Hortal & Lucas Jardim
Aim: The Island Rule – i.e. the tendency for body size to decrease in large mammals and increase in small mammals on islands has been commonly evaluated through macroecological or macroevolutionary, pattern-orientated approaches, which generally fail to model the microevolutionary processes driving either dwarfing or gigantism. Here, we seek to identify which microevolutionary process could have driven extreme insular dwarfism in the extinct dwarf red deer population on the island of Jersey. Location: Jersey, UK...
Positive forest cover effects on coffee yields are consistent across regions
Adrian González-Chaves, Luísa Carvalheiro, Lucas Garibaldi & Jean Paul Metzger
1. Enhancing biodiversity-based ecosystem services can generate win-win opportunities for conservation and agricultural production. Pollination and pest control are two essential agricultural services provided by mobile organisms, many depending on native vegetation networks beyond the farm scale. Many studies have evaluated the effects of landscape changes on such services at small scales. However, several landscape management policies (e.g., selection of conservation sites) and associated funding allocation occur at much larger spatial scales (e.g., state or...
