Native-Invasive Plants vs. Halophytes in Mediterranean Salt Marshes: Stress Tolerance Mechanisms in Two Related Species

2016

Dittrichia viscosa is a Mediterranean ruderal species that over the last decades has expanded into new habitats, including coastal salt marshes, ecosystems that are per se fragile and threatened by human activities. To assess the potential risk that this native-invasive species represents for the genuine salt marsh vegetation, we compared its distribution with that of Inula crithmoides, a taxonomically related halophyte, in three salt marshes located in “La Albufera” Natural Park, near the city of Valencia (East Spain). The presence of D. viscosa was restricted to areas of low and moderate salinity, while I. crithmoides was also present in the most saline zones of the salt marshes. Analyses…

A manipulative parasite increasing an antipredator response decreases its vulnerability to a nonhost predator.

2009

8 pages; International audience; Trophically transmitted parasites have to deal with the antipredator adaptations of their intermediate hosts. Some of these parasites induce behavioural changes in their intermediate hosts that make them more vulnerable to predation by definitive hosts. However, the adaptiveness of behavioural manipulation also depends on the probability of being eaten by a nonhost predator. Parasites might therefore try to use specific antipredator responses of intermediate hosts to avoid this dead end. We tested this hypothesis using the acanthocephalan Polymorphus minutus and its intermediate amphipod host, Gammarus roeseli. In their natural habitat, uninfected G. roeseli…

Spatio-temporal pattern of Pentastiridius leporinus migration in an ephemeral cropping system

2010

International audience; * 1 Cixiid planthoppers (Hemiptera: Fulgoromorpha: Cixiidae) are considered to be important economic pests because of their ability to transmit phloem-restricted prokaryotes causing emerging plant diseases worldwide. However, little information is available on the biology and ecology of such species. This is the case for Pentastiridius leporinus (Linnaeus), a cixiid planthopper reported to live on common reed across Countries of Central and Northern Europe. However, in the east of France, the same planthopper species appears to complete its life cycle in the sugar beet-wheat cropping system and has been repeatedly shown to transmit prokaryotic plant pathogens that ar…

A conspectus of the genus Cherleria (Minuartia s.l., Caryophyllaceae)

2017

Abstract: Minuartia s.l. (Caryophyllaceae) is polyphyletic, with its species belonging to eleven major clades, all of which have been recognized at the generic rank. Cherleria is one of these segregate genera, based on the Linnaean species Cherleria sedoides. Its centre of diversity is on the Balkan Peninsula, but species also occur in the European and North American high mountains and in the Arctic. The species of Cherleria show ecological, especially substrate, differentiation and multiple colonisations of alpine habitats. We make new combinations for the 17 (of 20) taxa in Cherleria that do not yet have Cherleria names and provide a key to all species of the genus. Citation: Moore A. J. …

Changes in the free amino acids and the biogenic amine contents during lactic acid fermentation of different lupin species

2016

Summary The aim of the work was to evaluate the profile of free amino acids (FAA) as the possible precursors of biogenic amines (BAs) in different varieties and hybrid lines of Lupinus luteus and Lupinus angustifolius and its changes during fermentation. Lupins have high amounts of FAA, and therefore, significant contents of BAs by the action of bacterial amino acid decarboxylases can be formed. In view of this, the effect of three Pediococcus pentosaceus strains KTU05-8, KTU05-9 and KTU05-10 on BA formation during lupin fermentation was studied. The formation of BAs was monitored during 48-h fermentation at solid-state conditions and compared with that in samples after submerged fermentati…

Community structure affects trophic ontogeny in a predatory fish.

2016

While most studies have focused on the timing and nature of ontogenetic niche shifts, information is scarce about the effects of community structure on trophic ontogeny of top predators. We investigated how community structure affects ontogenetic niche shifts (i.e., relationships between body length, trophic position, and individual dietary specialization) of a predatory fish, brown trout (Salmo trutta). We used stable isotope and stomach content analyses to test how functional characteristics of lake fish community compositions (competition and prey availability) modulate niche shifts in terms of (i) piscivorous behavior, (ii) trophic position, and (iii) individual dietary specialization. …

Population Trends of Cave-Dwelling Bats in the Eastern Iberian Peninsula and the Effect of Protecting Their Roosts

2017

Populations trends of cave-dwelling bats in the Eastern Iberian Peninsula and the effect of placing a perimeter fencing around their roosts (to avoid human disturbance on breeding colonies) were evaluated from 1997 to 2014. The species with the highest relative abundance was Miniopterus schreibersii (62.4%), followed by Myotis myotis/blythii (18%), and both populations showed positive trends. On the other hand, Myotis capaccinii (6.2%), M. escalerai (4.8%) and M. emarginatus (0.9%) showed significant, but minor increases, particularly in recent years. Rhinolophus mehelyi (0.2%) displayed no significant trends, while a moderate population decline was recorded for R. euryale (5.1%). Rhinoloph…

Essential Oils Extracted from Different Species of the Lamiaceae Plant Family as Prospective Bioagents against Several Detrimental Pests

2020

On the basis of the side effects of detrimental synthetic chemicals, introducing healthy, available, and effective bioagents for pest management is critical. Due to this circumstance, several studies have been conducted that evaluate the pesticidal potency of plant-derived essential oils. This review presents the pesticidal efficiency of essential oils isolated from different genera of the Lamiaceae family including Agastache Gronovius, Hyptis Jacquin, Lavandula L., Lepechinia Willdenow, Mentha L., Melissa L., Ocimum L., Origanum L., Perilla L., Perovskia Kar., Phlomis L., Rosmarinus L., Salvia L., Satureja L., Teucrium L., Thymus L., Zataria Boissier, and Zhumeria Rech. Along with acute to…
