Nutrient retranslocation in forest species in the Brazilian Amazon

open access: yesActa Scientiarum. Agronomy, 2016
Internal retranslocation is an important mechanism for nutrient conservation in plants, which depends on different factors. However, there are little data about this subject, especially on tropical forest species.

Pinus massoniana population dynamics: Driving species diversity during the pioneer stage of ecological restoration

open access: yesGlobal Ecology and Conservation, 2021
As a dominant and active component across ecological restoration processes, the population dynamics of pioneer tree species significantly affect species composition and community assemblage.

Drought resistance of native pioneer species indicates potential suitability for restoration of post-mining areas [PDF]

open access: yesWeb Ecology, 2015
In order to test whether invasive exotic species, predominantly used for restoring post-mining areas in north-eastern Vietnam, may be replaced by ecologically superior native pioneer species, we conducted a drought stress experiment in a greenhouse.

Microsatellite Analysis of Genetic Diversity in Indian Chicken Populations

open access: yesThe Journal of Poultry Science, 2007
Characterization of genetic diversity by employing molecular tools is a prerequisite in developing strategies for conservation and utilization of poultry genetic resources. We assessed genetic variation within and between six Indian chicken populations (

Morphological Features of Plants on Ash Settling Ponds. Case Study

open access: yesPlants, 2021
Owing to variable water conditions, chemical conditions of water or ash substrate, ash settling ponds belong to anthropogenic objects which do not easily undergo plant succession.

Carbon dioxide-enriched atmosphere enhances biomass accumulation and meristem production in the pioneer shrub Baccharis dracunculifolia (Asteraceae)

open access: yesActa Botânica Brasílica, 2014
The increase in atmospheric CO2 concentration predicted to the end of this century may cause several alterations on plant species development, which shall result in changes in the structure and function of plant communities.

Current State of Ammophila arenaria (Marram Grass) Distribution in the Eastern Cape, South Africa, and the Possible Effect of the Grass on the Dune System Dynamics

open access: yesPlants, 2022
The principal aim of this paper is to show that marram grass is not an invasive alien in South Africa although it affects the dune dynamics as a useful pioneer species in the dune successional process. The historical perspective of marram introduction as

Pioneer tree species accelerate restoration of tree‐related microhabitats in 50‐year‐old reserves of Białowieża Forest, Poland

open access: yesEcology and Evolution, 2023
Retention of structural elements such as deadwood and habitat trees at the level of forest stands has been promoted to integrate biodiversity conservation into multiple‐use forest management.

Successional Herbaceous Species Affect Soil Processes in a High-Elevation Alpine Proglacial Chronosequence

open access: yesFrontiers in Environmental Science, 2021
The study investigated plant-soil interactions along a proglacial chronosequence in the Italian Alps, with a specific focus on pioneer and grassland species structure and biogeochemical processes, with the aim to evaluate the biotic patterns in ecosystem
