Gender &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.

, 1986 The regeneration of interior Alaska’s commercial forest lands is mandated by Alaska’s Forest Resources and Practices Act (1979). This act requires that regeneration be established adequate to ensure a sustained yield on forested lands from which the ...

, 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 ...

New 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

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

A study of seed vigour test methodology variables : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Seed Technology at Massey University [PDF]
, 1998 Further research of some variables and procedures for promising seed vigour tests, such as the conductivity, Accelerated Ageing (AA) and Controlled Deterioration (CD) tests, is needed for their wider application and standardisation.

, 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

Rhizobial motility preference in root colonization of Medicago truncatula
New Phytologist, EarlyView.Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.
