Thresholds for impaired species recovery

2015

Studies on small and declining populations dominate research in conservation biology. This emphasis reflects two overarching frameworks: the small-population paradigm focuses on correlates of increased extinction probability; the declining-population paradigm directs attention to the causes and consequences of depletion. Neither, however, particularly informs research on the determinants, rate or uncertainty of population increase. By contrast, Allee effects (positive associations between population size and realized per capita population growth rate, r realized , a metric of average individual fitness) offer a theoretical and empirical basis for identifying numerical and temporal threshol…

Utility of island populations in re-introduction programmes--relationships between Arabian gazelles (Gazella arabica) from the Farasan Archipelago an…

2014

Understanding local adaptation and population differentiation is vital to the success of re-introduction initiatives. As other mammals living on islands, Arabian gazelles (G. arabica) show reduced body size on the Farasan archipelago, which we corroborated in this study through morphometric analyses of skulls. In the light of the steep population decline on the Arabian Peninsula – but stable population development on the archipelago – we tested the potential suitability of Farasan gazelles as a source for re-introductions on the mainland. We therefore investigated genetic differentiation between Farasan and mainland populations using eleven nuclear microsatellite loci and detected a distinc…

Lower cortisol response in high-resilient caregivers of people with autism: the role of anger

2016

Caring for an offspring with an autism spectrum disorder (ASD) has been related to high stress levels and health disturbances. However, a protective effect against these negative health outcomes has been described in high-resilient caregivers. In this context, the main aim of the present study was to assess the association between resilient coping and cortisol response to acute stress in caregivers of people with ASD. Furthermore, the study aimed to explore the mediating role of anger in this association. We exposed 40 caregivers of people with ASD to an acute psychosocial stressor in the laboratory. Salivary cortisol samples were obtained before, during, and after the stressor. Resilient c…

Background Coping plays an important role for emotion regulation in threatening situations. The model of coping modes designates repression and sensitization as two independent coping styles. Repression consists of strategies that shield the individual from arousal. Sensitization indicates increased analysis of the environment in order to reduce uncertainty. According to the discontinuity hypothesis, repressors are sensitive to threat in the early stages of information processing. While repressors do not exhibit memory disturbances early on, they manifest weak memory for these stimuli later. This study investigates the discontinuity hypothesis using functional magnetic resonance imaging (fM…

In situ behavior of wild long-snouted seahorse Hippocampus guttulatus Cuvier, 1829

2021

The study of behavior is one of the fundamental aspects of conservation biology. While for animals such as mammals there are well-defined protocols that have been applied for a long time, for marine animals, and fish in particular, studies are available for a limited number of species. The behavior of seahorses, for example, is poorly studied and in this work, we made a first attempt of using video recordings to analyze behavior of these endangered species in Mar Piccolo of Taranto (Southern Italy). The study presents preliminary data on behavioral activities and their comparisons among different life stages of Hippocampus guttulatus, namely females, males, and juveniles. Juveniles and fema…

Better Access to Terminology for Crisis Communications

2016

International audience; Crisis management depends on efficient communications with professional staff and with people who are affected by the crisis. The correct interpretation of general language and technical terms is crucial to take good actions and to save valuable time. To reduce the risk of misunderstandings we need a well-established crisis management terminology. Several collections of terms have been prepared for hazard areas such as pollution, radiation, fire safety, and dangerous goods. Today such terminologies can be provided on different websites, depending on how the national crisis management is organised. This distribution and a variation of different formats and user interf…

Sustainable recovery of critical elements from seawater saltworks bitterns by integration of high selective sorbents and reactive precipitation and c…

2023

The availability of raw mineral resources containing elements included in the Critical Raw Materials (CRMs) list is a growing concern for the European Union. Sea mining has been identified as a promising secondary source. In particular, brines obtained in solar saltworks (bitterns) contain relevant amounts of valuable CRMs such as Mg(II), B(III), other alkaline/alkaline earth metals (Rb(I), Cs(I), Sr(II)) and transition/post-transition elements (Co(II), Ga(III), Ge(IV)). However, the low concentration of some of these elements (µg/L) requires an effort to develop recovery routes that are sustainable and economically feasible where the required chemicals and energy are produced on-site from …

Conservation aspects for chasmophytic species: Phenological behavior and seed strategies of the Central Apennine threatened endemismMoehringia papulo…

2012

Abstract Chasmophytic vegetation growing on the cracks of cliffs in the Mediterranean and in the Euro-Siberian phytogeographic regions shows a great regional diversity, with a large number of endemic plant species, many of them endangered and at risk of extinction. Moehringia papulosa is an example of a threatened plant living in this kind of habitat. It is an endemism of the Marche region in central Italy, whose natural populations are considered as critically endangered (CR) under the IUCN criteria and the habitat is protected by the E.U. (Directive 92/43/EEC) with the habitat 8210 “calcareous rocky slopes with chasmophytic vegetation”. The phenology of natural populations was analyzed, s…

Conservation priorities for harlequin frogs (Atelopus spp.) of Peru

2005

Populations of harlequin frogs Atelopus are declining throughout their geographical range. In Peru six of the 11 nominally described species are Critically Endangered, and there are at least 17 undescribed additional forms (all representing apparently distinct species), the conservation status of which is unknown. Most Atelopus taxa in Peru have relatively small geographical ranges, some known only from single populations, and have only a limited chance of survival. Conservation will require: (1) improvement of the faunistic and taxonomic knowledge of the genus, (2) field surveys, including in remote areas, (3) assessment of all species and populations for chytridiomycosis and research on t…
