Yoruba Histories of Marriage and Belonging: Gender, Power and Innovation in Eighteenth‐Century West Africa

open access: yesGender &History, EarlyView.
ABSTRACT This article argues that marriage was central to historical change in the Yoruba‐speaking region of West Africa during the eighteenth century. It draws on ìtàn, a distinct oral source, to show that conjugality shaped Yoruba processes of urbanisation and political centralisation, gendered divisions of labour and social innovation and creativity.

Automation of the Acorn Scarification Process as a Contribution to Sustainable Forest Management. Case Study: Common Oak

open access: yes, 2017
The basic principle of silviculture is the rational use of natural regeneration. The acceleration and equalisation of seed germination and an increase of the field seed germination ability are affected by seed scarification, which results in the ...

Nonlinear criteria and the influence of the average principal stress on rocks destruction [PDF]

open access: yes, 2018
Purpose. Consider possible series methods of Mohr-Coulomb nonlinear criterion that takes into account stresses in the plane of fracture. Investigate the influence of the average principal stress on rocks destruction when cylinder modeling under axial and

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

open access: yesConservation Biology, EarlyView.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Effects of gut passage on the germination of seeds ingested by didelphid marsupials in a neotropical savanna

open access: yesActa Botânica Brasílica, 2013
We analyzed the effects that passage through the guts of seven didelphid species had on the seed germination of 10 plant species. This study was conducted in an area of riparian woodland in a cerrado (savanna) reserve in southeastern Brazil.

Assessment of Selected Parameters of the Automatic Scarification Device as an Example of a Device for Sustainable Forest Management

open access: yes, 2017
Due to technological progress in forestry, seedlings with covered root systems—especially those grown in container nurseries—have become increasingly important in forest nursery production. One the trees that is most commonly grown this way is the common

Germination and seedling establishment of Norway spruce (Picea abies) after clear-cutting is affected by timing of soil scarification

open access: yesNew forests, 2018
Natural regeneration of Norway spruce (Picea abies (L.) Karst.) is a relatively common practice in Norway on medium to low site indices. However, seedling establishment is often hampered by rapid regrowth of competing vegetation in scarified patches. The
