Importance of socio-economic and institutional factors in the collection of dry forest products: The case of gum and resin in Jawi District, Northwest Ethiopia

open access: yesTrees, Forests and People, 2023
Although the important role of dry forests in livelihoods is immense, empirical evidence on the role of socioeconomic factors in the collection of dry forest products is still lacking.

Tree canopy density thresholds for improved forests cover estimation in protected areas of Madagascar

open access: yesEnvironmental Research Communications, 2023
The rich endemic biodiversity of Madagascar is concentrated in different types of natural forests primarily conserved within the network of protected areas (PAs). Since 1990, remote sensing has been utilized to monitor forest cover.

Modeling forest bird population trends at U.S. Army Garrison Pōhakuloa Training Area, Hawaiʻi

open access: yesAvian Conservation and Ecology
Hawaiian avifaunal communities have suffered irrevocable harm and significant threats remain for extant species. It is increasingly important to monitor and document bird density to improve our understanding of how remaining species respond to changing ...

Can we set a global threshold age to define mature forests? [PDF]

open access: yes, 2015
Globally, mature forests appear to be increasing in biomass density (BD). There is disagreement whether these increases are the result of increases in atmospheric CO2 concentrations or a legacy effect of previous land-use. Recently, it was suggested that

Geographic distribution, conservation status and lectotypification of Pedersenia weberbaueri (Suess.) Holub (Amaranthaceae), an endemic and highly threatened shrub from the Marañón valley of Peru

open access: yesRevista Peruana de Biología, 2022
The present study analyses the geographical distribution, conservation status, and nomenclature of Peruvian endemic Pedersenia weberbaueri. The species distribution was modelled using MaxEnt based on occurrence data and bioclimatic variables.

Does degradation from selective logging and illegal activities differently impact forest resources? A case study in Ghana [PDF]

open access: yes, 2016
Degradation, a reduction of the ecosystem’s capacity to supply goods and services, is widespread in tropical forests and mainly caused by human disturbance.

Interaction of HS1BP3 with cortactin modulates TKS5 localisation, cell secretion and cancer malignancy

open access: yesMolecular Oncology, EarlyView.
Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...
