Fish on Fire: Shifts in Amazonian fish communities after floodplain forest fires

open access: yesJournal of Applied Ecology, Volume 60, Issue 8, Page 1637-1646, August 2023., 2023
Amazonian fish communities change after floodplain forest fires. Unburnt forests have diverse fish communities, with a large proportion of unique and small omnivorous species. In contrast, carnivores and detritivores become more common in fire scars and white‐sand savannas formed after forest fires. Less omnivore fish after forest fires can reduce tree

Effects of time since invasion and control actions on a coastal ecosystem invaded by non‐native pine trees

open access: yesEcological Solutions and Evidence, Volume 3, Issue 1, January–March 2022., 2022
Pine invasion reduced native species abundance, plant cover, richness and diversity, with an increase over time since invasion. Species diversity and richness were lower in the managed area than in the area that had not been invaded. Restoration activities are therefore required to increase native species diversity.

Is the search for cerebral palsy ‘cures’ a reasonable and appropriate goal in the 2020s?

open access: yesDevelopmental Medicine &Child Neurology, Volume 64, Issue 1, Page 49-55, January 2022., 2022
In the field of disability research and advocacy, the notion of ‘cures’ is contentious. Cerebral palsy (CP) is no exception. In this narrative review, we combine perspectives gained during community consultation undertaken for the Australian and New Zealand Cerebral Palsy Strategy, 2020 with those published in the scientific and grey literature to ...

Variation in biomass allocation and root functional parameters in response to fire history in Brazilian savannas

open access: yesJournal of Ecology, Volume 109, Issue 12, Page 4143-4157, December 2021., 2021
Fire stimulated the increase of absorptive root biomass in the upper soil layer in response to the higher demand for below‐ground resources, but did not promote modification of morphological root parameters. Differences in morphological root parameters reflected variation in soil properties, especially soil P, as well as differences in graminoid ...

Rat Olfactory Mucosa Mesenchymal Stem/Stromal Cells (OM‐MSCs): A Characterization Study

open access: yesInternational Journal of Cell Biology, Volume 2020, Issue 1, 2020., 2020
Stem/stromal cell‐based therapies are a branch of regenerative medicine and stand as an attractive option to promote the repair of damaged or dysfunctional tissues and organs. Olfactory mucosa mesenchymal stem/stromal cells have been regarded as a promising tool in regenerative therapies because of their several favorable properties such as ...

Relação entre a altura de inundação, riqueza específica de plantas e o tamanho de clareiras naturais em uma floresta inundável de igapó, na Amazônia Central Relationship between flooding level, plant species diversity and tree fall gap size in a seasonally flooded forest in Central Amazonia, Brazil

open access: yesRevista Árvore, 2005
Apesar do considerável número de estudos publicados sobre clareiras em regiões tropicais, nenhum deles foi publicado sobre a regeneração de espécies de plantas em clareiras naturais nas florestas inundadas da Amazônia.

Banco de sementes em sistemas de produção de agricultura com queima e sem queima no município de Marapanim, Pará

open access: yesBoletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2006
Na agricultura de corte e queima, a capoeira tem como papel principal a fertilização da terra após a queima de sua biomassa vegetal. Geralmente as repetidas queimadas acabam destruindo todas as formas de regeneração, incluindo o banco de sementes ...
