Title: Giant pangolin Smutsia gigantea (Illiger, 1815) Author(s): Hoffmann, Michael; Nixon, Stuart; Alempijevic, Daniel; Ayebare, Sam; Bruce, Tom; Davenport, Tim R B; Hart, John; Hart, Terese; Hega, Martin; Maisels, Fiona; Mills, David; Ndjassi, Constant Editor(s): Challender, Daniel W S; Nash, Helen C; Waterman, Carly Abstract: The giant pangolin (Smutsia gigantea) is the largest of all living pangolins, approaching a total length of 180 cm and a weight of more than 30 kg. The species is widely distributed in West and Central Africa in a variety of habitats, including primary and secondary forest, swamp forest and wooded savanna, ranging from Senegal to western Tanzania south to central Democratic Republic of the Congo. Primarily solitary and nocturnal, giant pangolins use their large muscular forelimbs to open subterranean termitaries in contrast to Temminck’s pangolin (S. temminckii) which do little digging. Available data suggest the species is uncommon and declining in many parts of its range, with no recent data for several countries from which it has been previously recorded. Despite their presence in many protected areas and international trade controls, hunting and poaching for bushmeat and international trade remains the primary threat to the species.

Title: Annexe sur l'abondance Author(s): Sop, Tenekwtche; Cheyne, Susan M; Kühl, Hjalmar S; Maisels, Fiona; Wich, Serge; Williamson, Elizabeth A Abstract: Cette annexe présente l’estimation de l’abondance des populations de grands singes par site. Le terme « site » correspond à une aire protégée et/ou à sa zone tampon, à une concession forestière ou à un ensemble de concessions, ou à tout autre territoire précis ayant fait l’objet d’un recensement au cours des 20 dernières années. Cette annexe mentionne cependant également quelques sites dont le dernier recensement remonte aux années 1970 ou 1980. La majorité des estimations sont extraites de publications validées par un comité de lecture ou de la littérature grise ; certaines ont été validées par des experts ayant accès à des informations qui ne relèvent pas du domaine public (données brutes et documents à l’attention de tiers non communicables en intégralité sans autorisation). Les colonnes des « années de recensement » indiquent la date du recueil des données sur le terrain ; quand il s’agit d’estimations basées sur des modélisations et non pas sur des observations de terrain, la date est suivie de « (modélis.) ». En ce qui concerne les taxons d’orangs-outans, toutes les estimations proviennent de modèles de projection (voir les tableaux 11 à 15). Les chiffres absolus étant rarement disponibles, le tableau 1 de cette annexe définit des catégories d’abondance, c’est-à-dire des fourchettes d’effectifs. Les estimations de densité disponibles sont fournies pour les gibbons.

Title: The Antarctic Ice Sheet and sea level: contemporary changes and future projections Author(s): Galton-Fenzi, Benjamin K; Fricker, Helen A; Bassis, Jeremy N; Crawford, Anna J; Gomez, Natalya; Schoof, Christian Editor(s): Meredith, Michael P; Melbourne-Thomas, Jess; Naveira Garabato, Alberto C; Raphael, Marilyn Abstract: Antarctica holds Earth’s largest ice sheet, which is slowly shrinking in response to climate warming. Over the coming decades to centuries, the loss of ice will likely continue and accelerate, potentially contributing several metres to global sea level rise. How fast and how much the Antarctic Ice Sheet (AIS) will continue to shrink is subject to “deep uncertainty”, which includes how rapid deglaciation can be triggered by feedback related to fracturing processes and vulnerabilities with regions grounded below sea level. In this chapter, we review our understanding of the key processes and potential feedback that can accelerate AIS retreat, and summarise its recent changes. We discuss future projections and what is understood by deep uncertainty in this context and then examine the consequences of AIS loss on global and regional sea level change. We close with a brief discussion of future research directions that will reduce gaps in our understanding of key ice-sheet processes and how these processes contribute to ice-sheet evolution, risks of rapid ice loss and implications for the research and planning needed to adapt to a changing sea level and climate.

Title: Ape Population Abundance Estimates Author(s): Sop, Tenekwtche; Cheyne, Susan M; Kuhl, Hjalmar S; Maisels, Fiona; Wich, Serge; Williamson, Elizabeth A Abstract: In this online-only annex, ape population abundance estimates are presented at the level of a protected area and/or its buffer zone, a logging concession or group of concessions, or any discrete area where a survey has taken place in the past two decades.
