Floristic composition in headwaters areas of the Piauitinga river Sub-Basin in ...
Calazans, Crislaine Costa; Freire, Gilmara da Silva; Prata, Ana Paula do Nascimento; Ferreira, Robério AnastácioDespite the riparian forest importance, it is evident that areas compose sub-basins undergo constant changes, culminating in these ecosystems’ degradation. Thus, the floristic composition of nine headwaters of the Piauitinga River Sub-Basin, located in Sergipe, Brazil, will be presented. A collection of botanical material was taken within a radius of 50 m from the water edge of each source. The taxonomic identi...
The use of species distribution modeling for forest restoration: A systematic r...
Amaral, Luise Andrade; Ferreira, Robério Anastácio; Mann, Renata SilvaThe objective of this work was to carry out a systematic review of the scientific production on the use of species distribution modeling for forest restoration. Searches for scientific articles in the Scopus and Web of Science databases for the last 15 years were performed in December 2020 using the terms: "ecological modeling" OR "biodiversity modeling" OR "predictive models" OR "modeling of niche" OR "habitat...
Survival of native forest seedlings in riparian forest at Sergipe State, Brazil
Jesus, Janisson Batista de; Ferreira, Robério Anastácio; Gama, Dráuzio Correia; Oliveira, Alisson Marcel Souza deThe objective of this study was to analyze the temporal behavior of seedlings survival from seeds without and with the application of treatment to overcome dormancy. We used native forest species, in a riparian forest area of the Piauitinga River, at the municipality of Lagarto, Sergipe State, Brazil. In the field, the design of the direct sowing was in randomized blocks, testing 5 native species (2 pioneer: Gu...

Sobral, Ivana Silva; Chagas, Danielle Costa Oliveira; Gomes, Laura Jane; Ferreira, Robério AnastácioEnviromental Protected Area South Coast Sul is one Protection Areas with serious problems about its implementation. An ineffi cient management added to environmental unconsciousness by the visitors and local community has deeply degraded its ecosystems. In attention to that situation, this work intended to show sustainability indicators to offer subsides to the manegement of tourism at this planning unit. The u...
Variabilidade genética de Spondias lutea L. em uma população do baixo São Franc...
Gois, Itamara Bomfim; Silva-Mann, Renata; Ferreira, Robério AnastácioThe knowledge about the reproduction system, its structure and genetic diversity are necessary for the genetic conservation of a species. This study aimed to determine the genetic diversity in a Spondias lutea L. population located in the Lower San Francisco River, Sergipe State, by isozyme markers; in order to allow elaborating strategies for seed production to restore a riparian forest. For this, young leaves...

Levantamento fitossociológico em área de Caatinga no monumento natural Grota do...
Ferraz, Raphael Cavalcanti; Mello, Anabel Aparecida de; Ferreira, Robério Anastácio; Prata, Ana Paula do NascimentoThe Caatinga is a vegetation that occurs exclusively in Brazil, typically in the Northeastern region and studies on the floristic composition and phytosociological are prerequisites for understanding the behavior, distribution and structure of the vegetation. Therefore, this study aimed to conduct a phytosociological survey of an area approximately 191 hectares of Caatinga, located within of the Unity Conservat...
Identificação de conflitos como estratégia para restauração florestal no riacho...
Hora, Fatima Maria Diaz da; Gomes, Laura Jane; Ferreira, Robério AnastácioExperiences in environmental management have showed the need for methodology research to restore riparian vegetation considering technical, not only encompassing social and environmental aspects, but also the social actors. The objective of this paper was to identify the social and environmental conflicts related to human activities as strategies in forest restoration in the Cajueiro dos Veados Rivulet hydrolog...
Efeito do estresse salino sobre atributos da germinação de sementes de girassol
Rabbani, Allívia Rouse Carregosa; Silva-Mann, Renata; Ferreira, Robério Anastácio; Álvares-Carvalho, Sheila Valéria; Nunes, Francisco Bruno da SilvaThe objective of this study was to evaluate the germination of sunflower seeds under different concentrations of sodium chloride at 0, 25, 50, 100, 200 and 250 Mol.m-3. The experiment was carried out with four replications of 25 seeds per treatment. The parameters evaluated were: percentage, index of speed germination, average time and average speed of germination. Treatment with highest germination was 25 Mol....
