- Abstract:
- ... The critically endangered and iconic plains-wanderer (Pedionomus torquatus) is phylogenetically distinct and endemic to south eastern Australia, and is a high conservation priority. Furthermore, it relies on critically-endangered native grasslands for its survival, which vary temporally in structure and hence do not always provide suitable habitat. To manage the remaining native grasslands appropr ...

- Abstract:
- ... The perennial sunflower Silphium integrifolium Michx. (Asteraceae), also known as silflower, is a prospective dual-purpose forage plus grain crop. Pre-flowering biomass harvest for animal feed and the subsequent delay in plant growth and anthesis has the potential to benefit seed yield and/or offset yield loss from native pests, such as the native North American Eucosma giganteana (Lepidopera: Tor ...

- Abstract:
- ... Mediterranean-type climate California experiences both frequent wildfires and periodic drought. Climate change models predict increased severity of drought, and wildfire size and frequency, leading to concern about the ability of some plant species to recover to pre-fire conditions when wildfires and drought coincide. During exceptional drought, drought-adapted native vegetation, such as perennial ...

- Abstract:
- ... QUESTIONS: In terms of biodiversity conservation, forest plantations are often considered problematic because they usually have negative effects on natural ecosystems. Soil seed banks could play an important role in restoring vegetation that was originally present, by recruiting species that have disappeared above‐ground. We addressed this topic in plantations located in the Patagonian steppe by a ...

Four single primer based DNA markers viz., ISJ, DAMD, ISSR and SCoT were used for genetic diversity analysis of 48 accessions of L. sindicus collected from 24 sites. The percentage polymorphic bands (PPB) produced for ISJ, DAMD, ISSR and SCoT were 86.73%, 75. ...

- Abstract:

It is commonly thought that fire promotes regeneration indirectly by reducing competition for light and providing gaps for recruitment, rather than directly stimulating germination. However, physiological dormancy and morphophysiological dormancy are common, and few studies have explored responses to fire‐cue ...

In this study, we compared the success of three restoration measures, spontaneous recovery, perennial‐crop–mediated restoration, and sowing native grasses, by using a unique combination of species‐based and trait‐based approaches. We sampled 373 4‐m² plots in nearly 1,000 ha of 20‐y ...

- Abstract:

In plants of water-limited ecosystems, tradeoffs between growth and water use may impose an important physiological constraint within and across species. I investigated how functional traits associated with this tradeoff differ between seed ...

Perennial herbaceous and woody plants were col ...

Agri-environment measures to support biodiversity in intensively used agricultural landscapes have been implemented in many European countries, but the large-scale downward trend in many species groups continues. The arable flora is one of the species groups that suffered the steepest declines in European cultural landscapes. Despite their fundamental importance in agroecosystems as the basis of t ...
