Accumulation of trace elements and tolerance to metal stress of the halophytes that colonize the edges of the lagoon of Bizerte (Tunisia).
The lagoon of Bizerte underwent a mixed anthropic pollution, essentially enhanced by the unlimited industrial waste derived from Iron Factory “ El Fouledh”, Industrial Refining Tunisian Company, Cement Company and from 400 industrial units established around it. This waste includes major pollutants conducive to a degradation of the ecological conditions of this lagoon. Previous research dealt with most of the different ecosystem components : soil, sediments, water, and aquatic organisms. In the present study, we have been interested in the halophytes inhabiting the edges of Bizerte lagoon. This study would allow us to identify the accumulating species to be used in the programs of phytoremediation. Shoots of Atriplex portulacoides, Arthrocnemum indicum, Salicornia arabica and Suaeda fruticosa were harvested, rinsed, dried and then crushed. Analyses were focused on few trace metals : Pb, Cu, Zn and Cd. Our results have allowed us to classify the halophytes “A. portulacoides, A. indicum, S. arabica and S. fruticosa” among the accumulating species of Pb (respectively 84.6, 92.2, 102.9 and 86.3 μg. g-1 DW), of Cu (respectively 14.5, 15.1, 24.2 and 14.9 μg. g-1 DW) and of Zn (respectively 1370.1, 625.1, 1601.4 and 772.5 μg. g-1 DW). Also, A. portulacoides and S. arabica are distinguished by their ability to store significant amounts of Zn which gives them a potential utility in the remediation programs. As regards Cd, we have shown that all studied species are hyper-accumulators of this metal (A. portulacoides : 274.0 μg. g-1 DW ; A. indicum : 280.4 μg. g-1 DW ; S. arabica : 211.6 μg. g-1 DW and S. fruticosa : 209.0 μg. g-1 DW). It should be noted that the harvested halophytes do not show any sign of toxicity, and they are able to accumulate more important amounts of heavy metals and to tolerate the metallic stress. These results show that the studied halophytes can be recommended for all programs of phytoremediation in polluted and salty areas.

Reproductive phenology and nestling diet of African Blue Tit Cyanistes teneriffae.
In this study, we investigated the reproductive phenology of Blue Tit (Cyanistes teneriffae) in a lowland Cork Oak (Quercus suber) of North-eastern Algeria. We analysed the diet of this species and the taxonomic characterization of prey and their water content. Nest boxes were installed on trees in late February and early March, at 2 meters above the ground and separated by 35-40 m. They were visited once a week from March 15 until July 15, noting the date, the timing and magnitude of spawning, the average number of chicks flown per nest and nest thickness. The diet was studied at different times of the season, harvesting of prey was carried out by the technique of laying collar in all chicks aged 5 to 9 days, and those two early season broods aged 12 days. The results showed that mean laying date is April 29, mean clutch size was 6.6 eggs per female, height of the nest positively related to laying date and number of fledged young. The average number of fledged chicks per nest is 4.5 and decreases during the season. The diet consists mainly of Lepidoptera larvae, but it is quite diverse with 33 species including 21 belonging to Lepidoptera, 6 to Orthoptera and three species of Arachnids. The rest of the diet consists of a species of Phasmid, Dictyoptera and Hymenoptera. Two peaks of food abundance were observed respectively in April 25-27 and May 1-4, and are diverse with respect to diet-season, consisting of adults and egg pockets. The amount of water in prey decreased during the season. The frequency of feeding of the chicks was higher at the age of 9 days than 15 days.

National distributional atlases and species inventory : toward a more iterative approach and a taxonomic balancing.
This synthesis analyses the use and limitations of the distributional atlases data for applied nature conservation studies. From the gaps and opportunities observed in France, we suggest a set of practical and scientific recommendations in order to strengthen their use in systematic conservation planning for terrestrial biodiversity (protected networks, green infrastructure and land settlement). The two main advices are to adopt an iterative approach between field survey and data analysis, and the selection of the species groups to inventory. The iterative process consists of regularly using available valid data to identify spatial and taxonomic gaps in the inventory, to model the potential distribution of each species and to estimate their ecological niche. During the distribution inventory project, this information can enable the sorting of new data according to their plausibility (data validation process) and should be used to identify priority areas for new field surveys. As scientific literature concludes that there is low consistency of biodiversity congruence relationship, we suggest increasing taxonomic representation in new atlases projects in order to provide a more complete view of species distribution for nature conservation initiatives. Ideally, the species groups should be rich in restricted range and low mobility species, or rich in habitat specialist species or contain species playing a recognized role in ecosystem functioning. Taking into account practical and technical criteria, a list of taxa is proposed for new distribution atlases. This proposal would cover about 20 % of known terrestrial species compared to current 5 %, with more effort on invertebrates, plants and fungi.
Typologie fonctionnelle et taxinomique des pinèdes de l’Algérois et de l’Oranais (Algérie)

Functional and taxonomic typology of pine communities in Algiers and Oran areas (Algeria).
Standard measurements of biodiversity, such as those based on species diversity and abundance, do not take into account the ecological and evolutionary characteristics of species per se, and provide us with an incomplete understanding of the causes and consequences of changes in biodiversity. Communities of Aleppo pines Pinus halepensis Mill. are under study in two Algerian phytogeographical areas : Algiers’ subhumid and humid bioclimate, and Oran’s semi-arid bioclimate. The purpose of this study is to analyse the floristic diversity of various communities of Aleppo pines, and to provide a typology based on twin approaches : a taxonomic analysis of the flora, and an analysis of the plants’ functional traits in these two areas. Correspondence factor analysis (CFA) has been conducted in both cases, and the results have been compared and discussed. The taxonomic analysis brings out contrasting ecological descriptors (altitude, substrate, etc.) and explains the plants’ distribution in relation to their environmental factors, but reveals no significant difference between the two areas under consideration. The functional analysis allowed for the identification of the main functional traits in each of the areas under study, and helped us define several functional groups in each case. A comparison of the results in both sectors shows that the organization of the Aleppo pine communities under consideration is principled upon phytogeographical, altitudinal, and disturbance gradients. Standard ecological factors evidenced by the taxonomic approach cannot single-handedly explain the dynamics of the communities ; however, their functional traits have clarified and supplemented the flora’s history in these two areas.
Analyse comparée à l’échelle mondiale des techniques d’ingénierie écologiques adaptées à la restauration des récifs coralliens

A comparative study at the global scale of ecological engineering techniques suitable for coral reef restoration.
To limit the impact of development projects on the decline of coral ecosystem while following a trend already started in Europe and in the world ; the French regulation has, since 2009, made obligatory the establishment of initiatives to offset the impacts caused to the environment. Artificial reefs and coral transplantation (or both together) are the two tools providing the most positive experience feedbacks worldwide. The study and comparison of 22 restoration projects of coral reefs conducted worldwide has shown that since the new regulatory obligations of mitigation, European projects have been multiplied, trying to find more effective techniques at lower costs. However, despite undeniable advances in applied research on the effectiveness of ecological engineering techniques used in experimental conditions, there is still no standard methodology of evaluation for each case of their application, in the context of mitigation measures for environmental impacts. This methodological gap often results in a gap between the “scientific” and the “practical” restorations and by frequent disagreement on the best practices for evaluation.
Suivi à long-terme dans la steppe d’Armoise blanche (Artemisia herba-alba Asso.) du Sud-Oranais (Algérie) : facteurs et indicateurs de changements

Long-term monitoring of Gray-leaved Sagebrush (Artemisia herba-alba Asso.) steppe in southern Oran Region (Algeria) : factors and indicators of change.
The Gray-leaved Sagebrush (Artemisia herba-Alba Asso.) steppes in the Southern Oran region in Algeria are rangelands of great pastoral interest. 40 years long-term dynamics of these steppes has been studied since 1975 using a diachronic monitoring (i) in permanent site considering five reference years and (ii) in 30 sites in the rest of the sagebrush steppe in 1975-76 and 2013-2015. Results generally show degradation with changes in the community composition and species dominance with appearance or extension of indicator species reflecting changes in land-use and environmental conditions. The increase in ephemeral species may explain the increase in the beta diversity, while the gamma diversity decreased underlying a trend toward banalization of the plant community composition. Unlike the rest of the pre-existing sagebrush steppe, in the monitoring site, following a series of rainy years, sand which had been fixed would have played an important role in the recovery of the vegetation cover.
Implications des communautés végétales péri-agricoles dans la dynamique environnementale des pollutions par les pesticides

Implications of field margin plant communities in the environmental dynamics of pesticides pollutions.
Several types of regulations, at the European and national levels, advocate setting up vegetative buffer strips in order to control or prevent the contamination of ecosystems by agricultural pollutions. The specific implication of the plant communities that are part of the make-up of buffer zones will be assessed in the context of agriculture-linked pollutions by pesticides. The distribution of environmental contaminations involving pesticides and associated products shows that plant communities of vegetative buffer strips are confronted with chemical and xenobiotic stresses that show great fluctuations and complexity, with, among other characteristics, exposures to mixtures of low levels of pollutants. The physical and microbiological dimensions of plant action on the environmental dynamics of contaminating pesticides are well understood, but higher plants are also capable of efficient responses to chemical and xenobiotic stresses and of phytoremediation of pollutants. However, the direct phytoremediating roles of plants in vegetative buffer-zones have remained poorly appreciated, and the interferences that affect this capacity for phytoremediation are not fully understood either. It is therefore essential that integrative studies take into account the diversity of contaminants, the diversity of plant species that are used in buffer zones, their capacity to respond to organic xenobiotics under laboratory controlled conditions, and their ecophysiological behaviour under real field conditions. Such studies will be useful to optimize the depollution capacities of buffer zones in relation with the various modalities of contamination and combinations of pollutants.
Suivi radio-télémétrique du Ganga cata (Pterocles alchata) en France. La faible survie observée questionne les effets de la capture et des émetteurs

Weak short-term survival of radio-tagged Pin-tailed Sangrouse (Pterocles alchata) in France raises questions about capture and attached transmitters.
Radio-telemetry is widely used by conservation biologists for collecting data on habitat use by animal species, a central topic in population ecology. For this purpose, the capture of individuals and attachment of transmitters on animals are necessary. Those actions might have a harmful effect on birds but when species are difficult to detect it remains the only method available. We report results of a radio-telemetry study on Pin-tailed Sandgrouse (Pterocles alchata) in France. Although the capture and attachment of transmitters are possible, short-term mortality is very high. Collected data do not explain such a rate. We compare those results to a recent study on the same species in Spain and to a meta-analysis on birds.

Use by small and medium mammals of wildlife crossing structures on two motorways in south-western France. Results of the first two years of camera-trap surveys.
Since 2012, camera-trap surveys have been carried out to study the use by wildlife of 9 newly-constructed underpasses on two motorways in south-western France (8 modified culverts and 1 underpass for small animals). A total of 5338 successful crossings of 16 small, medium and large mammal species were detected over a 9 to 24 month period (the duration varied with each site). The results comprise the majority of roadkill species, but micro-mammals were excluded from the survey. The mean observed daily crossing rate of 1.20 ± 0.70 SD per structure is comparable to other studies carried out in Western Europe at similar sites. Of the detected crossings, 91 % were made by 5 species : Eurasian badger Meles meles (45 %), Red fox Vulpes vulpes (19 %), Common rabbit Oryctolagus cuniculus (9 %), Common genet Genetta genetta (9 %) and Stone marten Martes foina (9 %). For these abundant species both the duration of the survey (number of days) and the season were shown to have a significant influence on the number of crossing events. Monitoring began shortly after the installation of each crossing structure. Over a 2-year period, an almost eight-fold increase in use was observed as wild fauna found the crossing structures and incorporated them into their movement patterns through adaptation periods and learning processes. Throughout the survey a decrease in refusal rate by Red fox and Badger was observed, supporting the ''habituation'' hypothesis. Usage was significantly different throughout the seasons for Badger, Red fox, Rabbit, and Stone marten. Each of these seasonal patterns could be correlated with species activity throughout the year. The initial survey results are encouraging and suggest that continued long-term monitoring is important to assess the effectiveness of crossing structures after the period of adaptation. To this end, our camera-trap surveys must be accompanied by appropriate additional sampling to measure the individual and population benefits for wildlife of these underpasses.

Contribution à la modélisation du flux de phosphore dans le barrage de Hammam Boughrara (province de Tlemcen, Algérie) : application à la gestion de l’eutrophisation.
Dans la présente étude portant sur le barrage de Hammam Boughrara, mis en eau en 1999, nous avons appliqué plusieurs modèles de bilan du phosphore, à savoir les modèles de Vollenweider (1969), de Dillon & Rigler (1975), de Walker (1977), de Reckhow (1977) et d’Ostrofsky (1978). Afin de prendre en considération la vitesse de submersion graduelle des surfaces inondées, caractérisée ordinairement par un accroissement très important de l’état trophique résultant des apports endogènes du phosphore par lessivage, nous avons tenté d’adapter le modèle d’Ostrofsky (1978) à la réalité du réservoir étudié, et ce en ajoutant une nouvelle dimension. Les résultats obtenus montrent que le modèle proposé semble pertinent.

Incursion ou non ? Étude des corrélations écologiques du conflit Homme-Éléphant dans le Ranch de Gibier de Nazinga (Burkina Faso)
Le phénomène de conflit Homme-Éléphant constitue une préoccupation majeure dans de nombreux pays en voie de développement. Cependant, on ne dispose que de peu d’informations sur sa dynamique dans les pays de l’Afrique de l’Ouest. Dans cet article, nous analysons les corrélations écologiques de la conservation de l’Éléphant (Loxodonta africana) dans dix villages riverains du Ranch de Gibier de Nazinga, au sud du Burkina Faso, au cours des années 2002 et 2006. Pour chacune des deux années, les corrélats de dégât d’éléphants étaient consistants : les éléphants ont attaqué préférentiellement trois villages du sud, tandis que sept villages du nord ont été pratiquement ignorés bien qu’aucune différence significative n’existait entre les distances de ces groupes de villages par rapport au Ranch. De plus, les éléphants ont surtout ciblé les plantations d’igname ou les plantations mixtes d’igname et de manioc; et pendant au moins un an, ils ont activement évité d’autres cultures (sorgho, maïs, mil et coton). Ils ont également ciblé les petites plantations. La taille de la population humaine dans chaque village n’a pas influencé la probabilité des dégâts (les trois villages-cibles du sud n’étaient pas plus petits en termes de taille de la population que les villages qui n’ont pas ou rarement été ciblés). La taille des groupes d’éléphants qui causaient les dégâts a été plus importante en 2006 qu’en 2002 . Les implications écologiques et en matière de conservation de ces patterns sont discutées dans cet article.

A peculiar lichenic association on False acacia (Robinia pseudoacacia L.) posts in farmlands : Strangosporo moriformis-Calicietum notarisii ass. nov. prov.
Description of a provisional new lichenic association named Strangosporo moriformis-Calicietum notarisii in which Strangospora moriformis (Ach.) Stein. and Calicium notarisii (Tul.) M. Prieto and Wedin are the characteristics. This association brings together on wooden vine or fence posts made with False acacia the pioneer, lignicolous, acidophilous, astegophilous and pollutolerant lichens of the lowland in the biogeographical region of the nemoral domain of France. The lichenic association is described on the basis of surveys carried out in Limagne in the Massif central, but its French distribution should be more extensive compared of the geographical distribution of the species that compose it.
Quarante ans de suivi dans la steppe du Sud-Oranais (Algérie) : changements de diversité et de composition floristiques

Forty years monitoring in an Algeria alfa steppe in southern Oran Region (Algeria) : plant diversity and composition changes.
The loss of plant diversity as a degradation feature in arid steppic rangelands is one of the crucial concerns in the southern Mediterranean countries. These rangelands are facing two interacting driving forces : the arid climate with recurring and more or less lasting droughts on the one hand, and overgrazing on the other. Long-term monitoring of change in diversity and composition of plant communities is considered to be the best way to understand the history and mechanisms of ecosystem degradation and desertification. Starting from a pre-existing community in which alfa (Stipa tenacissima L.) was the dominant and the keystone species regarding ecosystem structure and functioning, forty years monitoring allowed analysing changes in floristic richness, diversity and community composition prior attaining its current state of degraded and impoverished steppe.
