The Madagascar rosewood massacre
Valuable timber has been exploited from Madagascarâs rainforests for many decades, and Malagasy rosewood and palissandre (Dalbergia spp.) are among the most sought after hardwoods in the world. Large quantities have been harvested and exported at an increasing rate over the last decade, almost entirely from illegal logging in protected areas, in particular Masoala and Marojejy National Parks, which comprise part of the newly-established Atsinanana UNESCO World Heritage Site in the SAVA (Sambava - Antalaha-VohĂ©mar-Andapa) region of northeast Madagascar. We present information obtained from sources in the region that documents an unprecedented, highly organized expansion in the illegal timber trade operating openly in the wake of the countryâs current political turmoil, with more than 625 containers of rosewood worth an estimated US 130 millions du seul port de VohĂ©mar (Iharana), pour couvrir la demande du marchĂ© international. Les membres des communautĂ©s villageoises limitrophes des parcs de Masoala et de Marojejy ont peu profitĂ© de la manne que reprĂ©sente lâexportation de ce bois prĂ©cieux qui compromet par ailleurs lâintĂ©gritĂ© des zones protĂ©gĂ©es et leurs Ă©cosystĂšmes alors que la quasi-totalitĂ© des gains va Ă ceux qui organisent le trafic. Les revenus de lâĂ©cotourisme et dâautres activitĂ©s sont limitĂ©s aussi bien dans les parcs de Masoala que du Marojejy par le climat de la rĂ©gion, lâinaccessibilitĂ© relative et des infrastructures modestes qui font quâil est difficile aux gens de la rĂ©gion de rĂ©sister aux gains Ă court terme de lâexploitation forestiĂšre car elle reprĂ©sente leur seule bouĂ©e de sauvetage en cas de crise, quâil sâagisse dâun cyclone saisonnier ou dâune crise politique comme celle de 2009, dâautant que les agents des parcs nâont pas les moyens de sây opposer et ne sont pas assez nombreux. La course actuelle aux ressources des parcs et rĂ©serves de Madagascar compromet la lĂ©gitimitĂ© et la viabilitĂ© du plan de lâancien gouvernement de protĂ©ger 10% du pays et remet en cause lâengagement pour la protection de la nature du rĂ©gime actuel
Conservation status of vascular plant species from the QMM/Rio Tinto mining area at Mandena, Tolagnaro (Fort Dauphin) region, southeast Madagascar
A botanical inventory of the Mandena littoral forest, completed in 1991 as part of an environmental impact assessment study for a titanium oxide mining project being developed by QMM/Rio Tinto in the Tolagnaro (Fort Dauphin) region of southeastern Madagascar, identified 29 plant taxa as priorities for conservation, including 16 known only from the proposed mining path (Priority 1) and 13 restricted to the exploration zone (Priority 2). A re-evaluation in 2001 added 11 taxa from Mandena (the first of three sites targeted for mining, to be followed later by Petriky and then Sainte Luce) and removed 13 others, leaving a total of 27 taxa, five classified as Priority 1 and 22 as Priority 2. Using currently available data, we have removed four additional taxa from the list (three because populations were found outside the Tolagnaro area and one because itâs earlier inclusion on the list had been in error) and transferred four others from Priority 1 to Priority 2 as populations had been located within one or more of the newly - established conservation zones at Sainte Luce (747 ha), Mandena (230 ha) and Petriky (125 ha). Of the 15 currently recognized priority taxa present at Mandena, only two (an undescribed species in each of the genera Canthium and Pseudocatha) appear to be endemic there, but all remain a focus of QMMâs environment, conservation and restoration activities. A total of 15 Mandena taxa are listed as threatened on the 2008 IUCN Red List (3 Critically Endangered, 7 Endangered, and 5 Vulnerable), most of which must be regarded as important for conservation; only three of these taxa also appear on the priority list, and none of the 12 remaining priority taxa from Mandena have been assessed for the Red List, underscoring the urgent need to expand evaluation to encompass the entire Malagasy flora and in particular range-restricted taxa. RĂSUMĂ Un inventaire botanique de la forĂȘt littorale de Mandena, clĂŽturĂ© en 1991 dans le cadre dâune Ă©tude dâimpact environnemental portant sur un projet dâextraction miniĂšre dâoxyde de titane Ă©laborĂ© par QMM/Rio Tinto dans la rĂ©gion de Tolagnaro (Fort-Dauphin) au sud-est de Madagascar, a identifiĂ© 29 taxons de plantes prioritaires en matiĂšre de conservation, dont 16 taxons qui nâĂ©taient connus que des seules parcelles Ă exploiter (PrioritĂ© 1) et 13 taxons dont la distribution Ă©tait limitĂ©e Ă la zone dâexploration (PrioritĂ© 2). Une nouvelle Ă©valuation en 2001 ajouta 11 taxons de Mandena (premier site qui fera lâobjet de lâexploitation miniĂšre et qui sera suivi par Petriky puis Sainte Luce) et retira 13 autres taxons, ramenant ainsi la liste Ă 27 taxons dont cinq taxons de PrioritĂ© 1 et 22 de PrioritĂ© 2. En considĂ©rant les donnĂ©es actuellement disponibles, nous avons retirĂ© quatre autres taxons de la liste (trois taxons pour lesquels des populations ont Ă©tĂ© localisĂ©es au - delĂ de la rĂ©gion de Tolagnaro et un dernier taxon car son inclusion initiale sur la liste nâĂ©tait pas justifiĂ©e) et en avons dĂ©classĂ© quatre autres taxons en les passant de PrioritĂ© 1 Ă PrioritĂ© 2 avec des populations identifiĂ©es dans une ou plusieurs zone(s) de conservation nouvellement mise(s) en place Ă Sainte Luce (747 ha), Mandena (230 ha) et Petriky (125 ha). Sur les 15 taxons prioritaires actuellement reconnus et qui sont rencontrĂ©s Ă Mandena, seulement deux (une espĂšce non dĂ©crite dans chacun des genres Canthium et Pseudocatha) semblent y ĂȘtre endĂ©miques mais tous sont concernĂ©s par les activitĂ©s environnementales, de conservation et de restauration de QMM. Quinze taxons de Mandena figurent sur la Liste Rouge des espĂšces menacĂ©es 2008 de lâUICN (3 âen danger critique dâextinctionâ, 7 âen dangerâ et 5 âvulnĂ©rableâ) dont la plupart doivent ĂȘtre considĂ©rĂ©s comme importants pour la conservation ; seuls trois de ces taxons apparaissent Ă©galement sur la liste prioritaire alors quâaucun des 12 autres taxons prioritaires de Mandena nâa Ă©tĂ© Ă©valuĂ© pour la Liste Rouge, soulignant ainsi le besoin urgent dâĂ©tendre lâĂ©valuation pour inclure lâensemble de la flore malgache et plus particuliĂšrement les taxons avec des distributions rĂ©duites
Madagascarâs proposed domestic rosewood trade undermines species protection and exposes fatal flaws in the CITES regime
Madagascarâs proposal to expand its domestic trade in rosewood by allowing the use of logs from its âofficialâ stockpiles, which have been embargoed, undermines international conservation efforts and exposes critical weaknesses in the CITES regime. Despite the listing of all Malagasy rosewood species on CITES Appendix II and the implementation of a trade moratorium, illegal exports of rosewood persist, driven by criminal syndicates exploiting gaps in enforcement and forest governance. The proposal to remove 30,000 logs from CITES jurisdiction, purportedly for domestic use, lacks adequate safeguards to prevent their diversion into international markets. This move threatens to set a dangerous precedent for other countries, potentially facilitating illegal trade in other rare or endangered species. Immediate, stringent oversight and effective enforcement mechanisms are essential to mitigate these risks and uphold global conservation objectives.

Résumé
La proposition de Madagascar d'Ă©largir son commerce intĂ©rieur de bois de rose en autorisant l'utilisation des grumes provenant de ses stocks « officiels », qui avaient placĂ©s sous embargo, compromet les efforts internationaux de conservation et rĂ©vĂšle des faiblesses critiques dans le rĂ©gime de la CITES. MalgrĂ© l'inscription de toutes les espĂšces de bois de rose malgache Ă l'Annexe II de la CITES et la mise en place d'un moratoire sur leur commerce, les exportations illĂ©gales de bois de rose persistent, alimentĂ©es par des rĂ©seaux criminels exploitant les failles de l'application des lois et de la gouvernance forestiĂšre. La proposition de retirer 30 000 grumes de la juridiction de la CITES, soi-disant pour un usage domestique, ne prĂ©sente pas les garanties suffisantes pour empĂȘcher leur dĂ©tournement vers les marchĂ©s internationaux illĂ©gaux. Cette mesure risque de crĂ©er un prĂ©cĂ©dent pour d'autres pays, en facilitant potentiellement le commerce illĂ©gal d'autres espĂšces rares ou en danger. Une surveillance immĂ©diate et rigoureuse, accompagnĂ©e de mĂ©canismes d'application efficaces sont essentiels pour attĂ©nuer ces risques et maintenir les objectifs mondiaux de conservation
\u3cem\u3eAlectryon vitiensis\u3c/em\u3e: A New Species of Sapindaceae Endemic to Fiji
A new species of Alectryon Gaertn. (Sapindaceae) endemic to the Fijian archipelago is described as A. vitiensis Buerki, Lowry, Munzinger & Callm. based on morphological and molecular evidence. It can easily be distinguished from the two congeners currently known from Fiji by its smaller leaves, subsessile leaflets, apetalous flowers, and crested fruits. A phylogenetic analysis using ITS sequence data shows that the new species is closely related to two Australian endemics, A. diversifolius (F. Muell.) S. T. Reynolds and A. oleifolius (Desf.) S. T. Reynolds, but differs in having compound leaves covered with a golden indument. Moreover, the Australian taxa are associated with dry habitats, whereas the new species from Fiji is confined to evergreen humid forests. Among apetalous species (all of which belong to a well-supported clade), A. vitiensis morphologically most closely resembles the generic type, A. excelsus Gaertn., endemic to New Zealand, but they differ from one another in the type of indument covering their branches and leaves and the arrangement, shape, and nature of the indument on their leaflets; and they belong to different clades. The new species is provisionally assigned a conservation status of âEndangeredâ according to the IUCN Red List criteria
CITES must urgently take the steps to save Madagascarâs unique species of rosewood and ebony
This contribution is an open letter to all CITES Management and Scientific Authorities, which is signed by all of the co-authors. As CITES convenes its 19th Conference of the Parties in November 2022, some of the largest seizures in history of illegally harvested CITES-listed species are poised to be handed back to the criminals who smuggled them out of Madagascar. Nearly 40,000 rosewood logs were illegally exported from the country in 2014, in clear violation of CITES and national embargos, as explicitly declared in Notices issued by the CITES Secretariat. The logs were seized by Singapore, Kenya, and Sri Lanka, but as a result of both passive and active interference from various Malagasy officials and aggressive use of these countriesâ national court and political systems, orders have now been issued for the logs to be returned to the smugglers. Release of this wood would have catastrophic consequences for the future sustainable management of Madagascarâs remaining rosewood and ebony resources. We propose five essential steps that should be taken at the upcoming CITES CoP 19 in Panama to prevent this from happening
Identification of priority areas for plant conservation in Madagascar using Red List criteria: rare and threatened Pandanaceae indicate sites in need of protection
A major problem in establishing effective protocols for conserving Madagascar's biodiversity is the lack of reliable information for the identification of priority sites in need of protection. Analyses of field data and information from herbarium collections for members of the plant family Pandanaceae (85 spp. of Pandanus; 6 spp. of Martellidendron) showed how risk of extinction assessments can inform conservation planning. Application of IUCN Red List categories and criteria showed that 91% of the species are threatened. Mapping occurrence revealed centres of richness and rarity as well as gaps in Madagascar's existing protected area network. Protection of 10 additional sites would be required to encompass the 19 species currently lacking representation in the reserve network, within which east coast littoral forests are particularly under represented and important. The effect of scale on assessments of risk of extinction was explored by applying different grid cell sizes to estimate area of occupancy. Using a grid cell size within the range suggested by IUCN overestimates threatened status if based solely upon specimen data. For poorly inventoried countries such as Madagascar measures of range size based on such data should be complemented with field observations to determine population size, sensitivity to disturbance, and specific threats to habitat and therefore potential population decline. The analysis of such data can make an important contribution to the conservation planning process by identifying threatened species and revealing the highest priority sites for their conservatio
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers âŒ99% of the euchromatic genome and is accurate to an error rate of âŒ1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
Observation of gravitational waves from the coalescence of a 2.5â4.5 M â compact object and a neutron star
We report the observation of a coalescing compact binary with component masses 2.5â4.5 M â and 1.2â2.0 M â (all measurements quoted at the 90% credible level). The gravitational-wave signal GW230529_181500 was observed during the fourth observing run of the LIGOâVirgoâKAGRA detector network on 2023 May 29 by the LIGO Livingston observatory. The primary component of the source has a mass less than 5 M â at 99% credibility. We cannot definitively determine from gravitational-wave data alone whether either component of the source is a neutron star or a black hole. However, given existing estimates of the maximum neutron star mass, we find the most probable interpretation of the source to be the coalescence of a neutron star with a black hole that has a mass between the most massive neutron stars and the least massive black holes observed in the Galaxy. We provisionally estimate a merger rate density of 55â47+127Gpcâ3yrâ1 for compact binary coalescences with properties similar to the source of GW230529_181500; assuming that the source is a neutron starâblack hole merger, GW230529_181500-like sources may make up the majority of neutron starâblack hole coalescences. The discovery of this system implies an increase in the expected rate of neutron starâblack hole mergers with electromagnetic counterparts and provides further evidence for compact objects existing within the purported lower mass gap
