Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Establishing native wildflower habitats in urban settings on a low budget

Folia Horticulturae
This study aimed to compare the costs of two methods in establishing a native wildflower habitat using transplants while controlling weeds. The first method involved no-tillage and glyphosate herbicide and the second method used dazomet herbicide with ...

Multifunctional Bracts in the Dove Tree Davidia involucrata (Nyssaceae:Cornales) [PDF]

, 2008
Although there has been much experimental work on floral traits that are under selection from mutualists and antagonists, selection by abiotic environmental factors on flowers has been largely ignored.

A simple and affordable protocol to assess censer seed dispersal: First confirmation of the mechanism in the genus Solanum

Applications in Plant Sciences, EarlyView.
Abstract Premise The censer seed dispersal mechanism, whereby mature fruits are retained on plants and seeds dispersed by mechanical shaking, is among the most specialized wind‐aided seed dispersal strategies employed by the flowering plants. An efficient, affordable, and easily repeatable protocol for determining whether a species uses this unusual ...

The impact of urbanisation on social behaviour: a comprehensive review

Biological Reviews, EarlyView.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
