Waterlogging as an environmental filter to tree recruitment in tropical wet gra...
Ribeiro, Jonathan Wesley Ferreira [UNESP]; Gonçalo, Rafael Reis [UNESP]; Kolb, Rosana Marta [UNESP]Made available in DSpace on 2022-05-01T09:47:17Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Wet grasslands from the Brazilian Savanna (Cerrado) are open-canopy vegetation dominated by subshrubs and herbaceous plants. Although they frequently occur between gallery forests and savannas, tree species are rarely observed colonising these grasslands. Here, seed germination and seedling development ...
Woody plant encroachment constrains regeneration of ground-layer species in a n...
Pinheiro, Luiz Felipe Souza [UNESP]; Kansbock, Leticia [UNESP]; Rossatto, Davi Rodrigo [UNESP]; Kolb, Rosana Marta [UNESP]Made available in DSpace on 2022-05-01T13:57:12Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Woody plants have been encroaching into savannas on a global scale. Global climatic changes, along with changes to disturbance regimes, are considered to be the main drivers of this process. Particularly, many formerly open physiognomies of the Brazilian savanna have become encroached by woody species o...
Rocks and leaves: Can anatomical leaf traits reflect environmental heterogeneit...

No. of bitstreams: 0 Previous issue date: 2016-01-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Savanna vegetation maintains its openness and its diverse plant composition because of frequent fire events; however, when these are suppressed, encroachment is caused by ...
Distinct germination responses may contribute to the distribution pattern of tw...
Ferreira Ribeiro, Jonathan Wesley [UNESP]; Kolb, Rosana Marta [UNESP]Made available in DSpace on 2018-11-26T17:10:27Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-08-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Understanding how germination traits can influence the distribution pattern of adult plants is still an important issue for seed ecologists and biologists. Here, we evaluated if seed germination responses to abiotic factors may be related to...

A gravitational model for plant classification using adaxial epidermis texture
Backes, André Richard; Sá, Jarbas Joaci de Mesquita; Kolb, Rosana Marta [UNESP]Made available in DSpace on 2018-12-11T17:25:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-01-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); The leaves are very informative plant organs. They are extensively used in plant anatomical studies focusing taxonomy. Their both inner and outer structures provide very discriminant features from vegetal species. In this study, we pr...

Backes, André R.; de Mesquita Sá Junior, Jarbas Joaci; Kolb, Rosana Marta [UNESP]Made available in DSpace on 2018-12-11T17:29:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-01-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); The leaves are an important plant organ and source of information for the traditional plant taxonomy. This study proposes a plant classification approach using the adaxial epidermis tissue, a specific cell layer that covers the leaf. ...
