Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

The effect of light supplementation on the changes in outer and inner fruit quality of different Selenicereus spp. cultivars

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Selenicereus spp., belonging to the Cactaceae family, produces pitaya, a fruit recognized for its exotic appearance and rich phytochemical composition. In regions with shorter photoperiods, flowering and fruit development are limited, making light supplementation a promising strategy.

Northern bobwhites associated with native grass and shrubs have improved survival

open access: yesThe Journal of Wildlife Management, EarlyView.
Survival rates of adult northern bobwhites were improved by a combination of grazed native warm‐season grasses and well‐interspersed shrubs. Our study suggests that incorporating native warm‐season grass cattle forages into existing operations across the southeastern United States may be a viable working‐lands conservation strategy to create habitat ...

Agent‐Related Perceptions of Automated Versus Human Agents and the Role of Task‐Related Risk: A Meta‐Analysis

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Firms often seek to replace human agents (HAs) with automated agents (AAs) for customer service, but customers still tend to react more negatively to AAs than to HAs. This meta‐analysis examines agent‐related perceptions (i.e., humanlikeness, warmth, and competence), which represent the key upstream customer reactions shaping downstream ...

Quarantine is important in restricting the spread of exotic seed-borne tree pathogens in the southern hemisphere [PDF]

open access: yes, 2002
The lack or destruction of indigenous forests in the southern hemisphere has in some cases led to extensive afforestation with exotic softwoods that subsequently developed into large successful forestry industries.

Two new endemic species of Portulaca (Portulacaceae) from the Brazilian Pampa grasslands

open access: yesNordic Journal of Botany, EarlyView.
Portulaca L. is a monophyletic, cosmopolitan genus of succulent plants comprising ca 153 species, with particularly high diversity in xerophytic ecosystems in tropical and subtropical regions. Based on morphological evidence, we describe and illustrate two new species from the Brazilian Pampa, Portulaca guaritensis and Portulaca guenoa.

Interplanetary frontiers: terraforming from an invasion science perspective

open access: yesOikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Mechanisms and impacts of future plant invasions: research agendas and management needs under disruptive social‐ecological change scenarios

open access: yesOikos, EarlyView.
No‐analogue futures are characteristic of the Anthropocene, but how global change, and societies' responses, will affect plant invasions remains unclear. Conducting research now to address future needs is crucial for guiding invasion management and policy.
