Plant ontogeny is a common source of variation in defense and herbivory. Yet, few studies have investigated how the induction of physical defense traits changes across plant ontogeny. Physical defense traits are costly to produce, and thus, it was predicted that induction as a cost-saving strategy would be particularly favorable for seedlings, leading to ontogenetic declines in the inducibility...

Since their introduction at the beginning of 19th century, Casuarina species have become important components Algerian landscape, yet numbers present in Algeria and identity, distribution, symbiotic status are still not well understood. A survey conducted on 2,304 trees 96 stands across indicates that they represented exclusively by five species: cristata Miq., C. cunninghamiana equisetifolia L...

Nocardia sp. strain BMG111209 is a non-Frankia actinobacterium isolated from root nodules of Casuarina glauca in Tunisia. Here, we report the 9.1-Mbp draft genome sequence of Nocardia sp. strain BMG111209 with a G + C content of 69.19% and 8,122 candidate protein-encoding genes.

The temperate deciduous species Nothofagus glauca (Phil.) Krasser exhibits characteristics commonly found in fire-adapted vegetation, yet the role of fire in the evolutionary history of the vegetation in south-central Chile has not been well investigated. We examined the effects of a wildfire on early succession in a Nothofagus glauca forest in the Coastal Cordillera of south-central Chile by c...

INTRODUCTION Nicotiana glauca (wild tobacco, tree tobacco), a member of the Solanaceae family, is a slender shrub or a small erect tree growing up to 5 m high with long, lax branches (Fig. 1). This plant is a native of Argentina that has become widespread in South Africa, occurring mostly on disturbed soil such as old lands, trampled areas and road verges. It is also a common weed along inland ...

Marine ecosystems are constantly being threatened by contaminants produced by human activities. There is an urge to better understand their impacts on marine organisms and develop reliable tools for biomonitoring studies, while also assessing their potential impacts on human health. Given their position on top of food webs, sharks are particularly susceptible to bioaccumulation, making them pot...
