This thesis is the report of this long process, but it cannot express the long days spent in both the field and the lab, battling shoulder to shoulder with my fellow scientists. It cannot also express the stress, the sadness and the tiredness because of the war and the victims in my country (Syria). The first year was only just unsuccessful attempts to detect both the nuclear microsatellite markers and the chloroplast markers (we used 4 pairs of universal primers (MatK 390F / 1440R, TrnK-MatK 3914F / 1110R, TrnL-trnF e / f and Trnt-L La / Lb), in dry and old herbarium’ specimens (Paris’ herbarium, Montpellier’ herbarium, Geneva’ herbarium and Barcelona’ herbarium). A new and different scheme to search was established in the second year. This work is to the best of my knowledge original except where references are made to previous work. This thesis has been writing based on experiments conducted in the scientific group of both two laboratories Center for Ecology and Conservation Sciences (CESCO; MNHN) and Ecology, Systematics and Evolution (ESE, CNRS, University of Paris-Sud Saclay). I would like to thank my supervisors Nathalie MACHON and Sonja SILJAK-YAKOVLEV for their excellent guidance and support during this process. It is great to have finally completed my thesis. Within, this interesting subject, I have gained much knowledge and discovered a domain, where I like to work in the future. At the end, thanks to you, reader, if you are reading this line after the others, you at least read one page of my thesis. Thank You VII Summary of the thesis Population-level conservation is being extremely required to restrain the biodiversity loss within a species. So, the assessment of the variability within the species complex is being renowned as an important first step to well implement the future conservation settings for threatened species. The species complex of Arenaria grandiflora is a short-lived perennial herbaceous and a threatened taxon in certain of sites of its distribution areas in Europe, with unresolved genetics and taxonomy, which lead to potential problems in the conservation and utilization of the resource. A differentiation among populations of the species complex of A. grandiflora is presented in this study based on the genetic, cytogenetic and phenotypic patterns. Intraspecific ploidy level variation is an important aspect of numerous species, so, the present study explores this phenomenon within the A. grandiflora species complex in some type of populations (27 natural populations). To infer the intraspecific genetic and cytogenetic patterns of variability among the studied natural populations of the investigated species complex (A. grandiflora), three methods were used: nuclear microsatellite markers, cytogenetic and flow cytometry approaches. Moreover, the phenotypic patterns of variation among both the stock of seeds and the herbarium materials of A. grandiflora were defined. These patterns were detected using three methods of seed germination (in vitro culture, filter papers and potting soil) and morphometric approaches. A significant differentiation among populations’ patterns of molecular, cytogenetic and phenotypic variation was detected within the A. grandiflora species complex. Presence of two closely related cytotypes (diploids 2n=2x=22 and tetraploids 2n=4x=44) was detected using both classical and more recent methods (chromosome number count and flow cytometry respectively). The species complex of A. grandiflora exhibits high variation in 2C-DNA value, the genome size ranges from 2.11±0.74 pg to 2.70±0.11 pg for the diploid populations and from 4.30±1.51 pg to 5.27±0.14 pg for the tetraploid populations. Moreover, the seeds of tetraploids germinate well and in high proportion than the seeds of the diploid ones. In addition, both acicular and linear leaves from the diploid populations differ significantly within the diploids and with the lanceolate leaves of the tetraploid ones. New protocol of seed germination for the tetraploids by in vitro culture after scarifying was described for the first time. The affected factors on seed germination percentages were determined by an explanatory model of six predictors (altitude, longitude, latitude, ploidy levels, both period and condition of seed storage). VIII Consequently, all these findings are fundamental for the determination of the evolutionarily significant units (ESUs) within A. grandiflora species complex and thus the definition of efficient restoration plans in the future. This study would consider as the preliminary signal for necessary revision for the intraspecific taxonomic keys problematic for this species complex. IX Table of Contents 1.

    Chimpanzees Balance Resources and Risk in an Anthropogenic Landscape of Fear Elena Bersacola1,2,3*, Catherine M

    www.nature.com/scientificreports OPEN Chimpanzees balance resources and risk in an anthropogenic landscape of fear Elena Bersacola1,2,3*, Catherine M. Hill2 & Kimberley J. Hockings1,3 Human-wildlife coexistence is possible when animals can meet their ecological requirements while managing human-induced risks. Understanding how wildlife balance these trade-ofs in anthropogenic environments is crucial to develop efective strategies to reduce risks of negative interactions, including bi-directional aggression and disease transmission. For the frst time, we use a landscape of fear framework with Bayesian spatiotemporal modelling to investigate anthropogenic risk-mitigation and optimal foraging trade-ofs in Critically Endangered western chimpanzees (Pan troglodytes verus). Using 12 months of camera trap data (21 camera traps, 6722 camera trap days) and phenology on wild and cultivated plant species collected at Caiquene–Cadique, Cantanhez National Park (Guinea-Bissau), we show that humans and chimpanzees broadly overlapped in their use of forest and anthropogenic parts of the habitat including villages and cultivated areas. The spatiotemporal model showed that chimpanzee use of space was predicted by the availability of naturalised oil-palm fruit. Chimpanzees used areas away from villages and agriculture more intensively, but optimised their foraging strategies by increasing their use of village areas with cultivated fruits when wild fruits were scarce. Our modelling approach generates fne-resolution space–time output maps, which can be scaled-up to identify human-wildlife interaction hotspots at the landscape level, informing coexistence strategy. Te majority of the world’s terrestrial biodiversity is impacted by humans 1,2. Anthropogenic activities, includ- ing hunting and forest conversion to agriculture, pasture land and urban areas are causing signifcant wildlife population declines globally 3.

McGough Wildlife Service Ireland DUBLIN PUBLISHED BY THE STATIONERY OFFICE 1988 ISBN 0 7076 0032 4 This version of the Red Data Book was scanned from the original book. The original book is A5-format, with 168 pages. Some changes have been made as follows: NOMENCLATURE has been updated, with the name used in the 1988 edition in brackets. Irish Names and family names have also been added. STATUS: There have been three Flora Protection Orders (1980, 1987, 1999) to date. If a species is currently protected (i.e. 1999) this is stated as PROTECTED, if it was previously protected, the year(s) of the relevant orders are given. IUCN categories have been updated as follows: EN to CR, V to EN, R to V. The original (1988) rating is given in brackets thus: “CR (EN)”. This takes account of the fact that a rare plant is not necessarily threatened. The European IUCN rating was given in the original book, here it is changed to the UK IUCN category as given in the 2005 Red Data Book listing. MAPS and APPENDIX have not been reproduced here. ACKNOWLEDGEMENTS We are most grateful to the following for their help in the preparation of the Irish Red Data Book:- Christine Leon, CMC, Kew for writing the Preface to this Red Data Book and for helpful discussions on the European aspects of rare plant conservation; Edwin Wymer, who designed the cover and who, as part of his contract duties in the Wildlife Service, organised the computer applications to the data in an efficient and thorough manner.

The species is best known for the edible seeds and oil it produces. In addition, it has numerous environmental, socio-economic, traditional and industrial uses. However, the species is declining at an alarming rate and thus, needs priority conservation. This decline is due to a number of factors of which are high rate of deforestation, increased population pressure, non-improvement and non-cultivation of the species. Urgent conservation measures are required to save the species. The conservation strategies could include; mass propagation and plantation establishment of the species, development of early- maturing and dwarf varieties as well as introduction of ‘Ukwa’ trade fair. Keywords: Forest Fruit Tree, Treculia africana, Endangered, Southern Nigeria INTRODUCTION Treculia africana is a multipurpose tree species commonly known as African breadfruit. It belongs to the family Moraceae and it grows in the forest zone, particularly the coastal swamp zone (Agbogidi and Onomeregbor, 2008). It is widely grown in Southern Nigeria for its seeds and it is known by various tribal names in the country. Such names include ―afon‖ (Yoruba), ―barafuta‖ (Hausa), ―ize‖ (Bini), ―eyo‖ (Igala), ―ediang‖ (Efik) and ―ukwa‖ (Igbo) [Irvine (1981) Onweluzo and Odume (2008)].
