Abstract:
SummaryThe Seychelles Warbler was once a highly threatened single-island endemic species with a population of 26 individuals confined to Cousin Island in the inner Seychelles. Following long-term management of Cousin, the population steadily recovered to around 300- 360 birds. Given the vulnerability of one small island in the Indian Ocean, the possibility of establishing the species on additional islands had been proposed as a priority conservation measure. This paper describes the successful translocation of 29 Seychelles Warblers from Cousin to Aride, summarizes the ecological studies carried out prior to, during and after the translocation and documents the subsequent establishment of the new population. It is considered that the Seychelles Warbler will soon no longer be a globally threatened species.

Abstract:
The distribution of the forest tree Pisonia grandis (Nyctaginaceae) coincides with seabird colonies on small tropical islands. Its seeds are enclosed in a calyx exuding extremely sticky resin which adheres strongly to feathers. Birds are obviously seed-dispersal vectors, but the multi-seeded infructescences frequently entangle birds, often fatally. On Cousin Island, Seychelles, I investigated the production, germination, survival, and tolerance to seawater of Pisonia seeds, and the occurrence of entanglement with birds. Fresh seeds had high germination success (62–87% in experimental trays), but seedling survival in Cousin's forests was low (0.1% of 6020 seeds survived as seedlings after 2–8 mo). Some seeds tolerated 30 min daily immersions in seawater (8–15% germination after 14–28 d treatment), but not continuous immersion in seawater (reduced germination after 5 d and none after 12 d). Inter-island dispersal is likely via living unencumbered seabirds carrying a few seeds, but not on floating carcasses. Seeds attached to carcasses did not have improved germination or survival. Intra-island propagation is almost entirely vegetative, with negligible local seed dispersal. Pisonia plants therefore do not benefit from fatal entanglements. The extreme stickiness of the seeds evidently evolved to resist removal by seabirds and so facilitate long-distance dispersal. The mortality of some potential vectors is an unfortunate consequence, but has little impact on the large populations of tree- and ground-nesting seabirds which nest in or under these trees.

Abstract:
Abstract Maximum diving depths were measured for shearwaters breeding on Cousin Island, Seychelles. Eighty-three percent of 23 Wedge-tailed Shearwaters (Puffinus pacificus) dived, and their mean maximum depth was 14 m (SD = 23 m, range 1–66 m, N = 19). All Audubon's Shearwaters (P. lherminieri) dived, and their mean maximum depth was 15 m (SD = 12 m, range 6–35 m, N = 7). These data contradict the hypothesis that tropical shearwaters should not specialize in underwater foraging. They are capable of exploiting deep prey unavailable to most other tropical seabirds. Five Puffinus species (temperate and tropical) attained allometrically scaled maximum depths comparable to those of penguins and alcids.

Abstract:
SummaryIn the 1950s the Seychelles Warbler Acrocephalus sechellensis was a highly threatened single-island endemic species with a population of 26 individuals confined to Cousin Island in the inner Seychelles. Following long-term management of Cousin, the population steadily recovered to around 300–360 birds. In order to give the species the security of additional breeding populations, some warblers were successfully transferred to the islands of Aride and Cousine in September 1988 and June 1990 respectively. During the three years after the transfer to Aride and the first year after the transfer to Cousine, mean territory quality (measured as insect prey available) on these islands was significantly higher than that on Cousin, leading to higher reproductive success per territory and survival of juveniles and adult birds. In November 1991, all transferred birds were still alive, and 205 young had fledged successfully, bringing the total warbler population to c.585 birds. By then there was enough suitable space still remaining on Aride and Cousine for young birds to establish territories and the rise in warbler numbers is expected to continue. The successful establishment of three self-sustaining and viable breeding populations has ensured that the Seychelles Warbler is no longer a globally threatened species.

Abstract:
SummaryThe once ‘Critically Endangered’ Seychelles Magpie-robin was down to just 12 individuals in 1960 on one island of the granitic Seychelles. In 2015, due to intensive long-term management the population stands at around 280 birds on five islands, marking a significant success for this species. Translocations to the islands of Cousin and Cousine have led to population saturation and stability, a translocation to Denis Island has resulted in a continuing population increase and the founder population on Frégate Island is likewise increasing. The latest translocation to Aride Island in 2002 resulted in population increase then stability but is now showing a steep decline throughout 2014 into 2015. Reasons for this decline are yet unknown though disease, lack of recruitment, the impacts of social conflict and the possibility of genetic issues are discussed. This report summarises the history of management for this species, compiling all available published and unpublished information, to provide a comprehensive account of the Seychelles Magpie-robin recovery.

Abstract:
In this study, we examine a recent sample containing two hawk moth species (Lepidoptera: Sphingidae) from Praslin and Mahé, Seychelles. It was widely accepted that the hawk moth species Temnora peckoveri (Butler, 1876) has a disjunctive range covering Madagascar and the Inner Seychelles. However, the Seychelles population of what was thought to be Temnora peckoveri shares a set of diagnostic morphological differences from both this species and T. fumosa (Walker, 1856) in the male genitalia structure. In particular, it remotely resembles Temnora fumosa based on the structure of aedeagus but differs from T. fumosa and T. peckoveri with respect to the harpe shape. Based on this evidence, we describe Temnora fumosa seychellensis Bolotov & Spitsyn ssp. nov. as a subspecies with restricted range, being endemic to the Inner Seychelles. The range of this subspecies covers Praslin (first record), Mahé, Silhouette, La Digue, Cousine, and Denis. Additionally, we report on recent occurrences of Agrius convolvuli (Linnaeus, 1758) from Praslin (second record) and Mahé. The adult moths were recorded feeding on inflorescences of Dracaena reflexa var. angustifolia Baker (Asparagaceae) for the first time. Finally, we present a complete list of Temnora fumosa seychellensis ssp. nov. and Agrius convolvuli occurrences from Seychelles.

Abstract:
A new species of indotyphlid caecilian amphibian, Hypogeophis montanus sp. nov., is described based on a series of specimens from the Seychelles island of Mahé, collected from two localities in 2013 and 2015. The new species most closely resembles the Seychelles (Mahé) endemic H. brevis in being short (maximum known total length in life ca. 110 mm) and long snouted, but differs by having more vertebrae, a relatively smaller head, and substantially distinct mitochondrial and nuclear gene sequences. Hypogeophis montanus sp. nov. is known from higher elevations (718–731 m) than H. brevis (ca. 350–650 m), and its elevationally restricted distribution on a single small island likely renders it threatened under IUCN Red List criteria. Hypogeophis montanus sp. nov. is the third species of small and long-snouted caecilian reported from the Seychelles. Along with H. brevis and H. pti, H. montanus sp. nov. is among the smallest known species of caecilian and possibly has the smallest global distribution.

Abstract:
Seychelles Black Paradise-flycatcher Terpsiphone corvina is found almost exclusively on the 10 km2 island of La Digue. It is currently considered the second rarest endemic bird in the Seychelles, using the criteria of total population and number of discrete populations. Research reassessing the habitat requirements of the flycatcher was conducted on La Digue from 1999 to 2001. This work was conducted in parallel with assessment and ranking of the suitability of medium-sized islands of the inner Seychelles archipelago for avian ecosystem restoration, using biological, geographical and anthropogenic criteria. Predator eradications on several islands have led to a reduction in the range of alien predators, and future eradications are planned. These developments combined with the findings of recent ecological research and a novel assessment of many islands in the archipelago have led to the opportunity for a reassessment of conservation options for Seychelles Black Paradise-flycatcher. This paper discusses and prioritizes strategies to increase the range and total population and hence improve the conservation status of this species.

Abstract:
An extensive bleaching event in the summer of the year 1997-1998 affected most reefs along East Africa's shores. In the aftermath of that episode, the reefs of Île Alphonse in the Seychelles were examined and it was found that reefs along the seaward slopes of the island lost >95% of their branching coral colonies, with considerably higher survival of massive species. Île Alphonse features a nearly circular shallow lagoon, with steep seaward slopes. Contrary to our expectations, mortality in the warmer lagoon was far lower than of coral colonies on the surrounding slopes, bathed in deeper and cooler waters. We suggest that corals in the lagoon were protected from UV radiation by leachate stemming from seagrass leaves steeped in the lagoon. Our measurements in the lagoon showed a strong attenuation of ultraviolet radiation, not observed in the waters outside the lagoon, and laboratory examination confirmed that the strong UV absorption of substances leached into seawater from decomposing leaves of the seagrassThalassodendron (=Cymodocea) testudinaceum. Our findings demonstrate the synergism between elevated seawater temperature and UV radiation in triggering bleaching on shallow reefs.

Abstract:
Abstract The western Indian Ocean holds five subspecies of the pantropical Audubon's Shearwater (Puffinus lherminieri), but none was known to breed in the Mozambique Channel. Here, I describe a newly discovered population of Audubon's Shearwaters on Europa Island, southern Mozambique Channel. Comparison of geographic variation of morphometric characters showed that the birds of this population belong to the P. l. bailloni subspecies, previously thought to be endemic to the Mascarenes Islands. They were distinct from the three subspecies of the Comoro, Aldabra, and Seychelles group, suggesting that few successful exchanges of individuals occur between north of the Mozambique Channel and Europa Island. This biogeographic pattern is similar to that of two phylogenetically independent pelagic species from Europa Island. This suggests that a common cause related to geographic isolation and oceanic conditions in the Mozambique Channel may explain the apparent isolation of these three seabird populations from Europa Island.

Abstract:
Abstract We describe the main reproductive characteristics (laying date, egg size, hatchling mass, and breeding success), chick growth, and patterns of provisioning in Lesser Noddies (Anous tenuirostris) on Aride Island, Seychelles, 1995–2002. The bulk of the population laid eggs between late May and late June in most years. Both hatching and fledging success varied significantly between years, with fledging success (2–92%) more variable than hatching success (28–91%). Productivity of less than 0.10 chicks per breeding pair occurred in 25% of the years. In 2001, egg volume did not differ significantly between hatched and unhatched eggs. Chick mass at hatching was significantly correlated with an egg volume index, but there were no correlations between egg size and either hatching date or linear growth rate. Around 40% of the Lesser Noddy chicks were fed at dusk. Chicks aged 0–5 and 6–10 days received significantly less food than older chicks. There was evidence of daily and stochastic variation in the foraging success of individual birds. Comparing similar studies, chicks of Lesser Noddies and Sooty Terns (Sterna fuscata) appeared more resistant to fluctuating food supplies than those of Roseate Terns (Sterna dougallii), indicating that, in tropical seas, slow growth and foraging farther offshore are more advantageous than faster growth and inshore feeding. Datas de Postura, Alimentação dos Filhotes e Sucesso Reprodutivo de Anous tenuirostris na Ilha de Aride, Seychelles Resumo. Neste estudo descrevemos as principais características da biologia reprodutiva (datas de postura, tamanho dos ovos, peso dos filhotes ao nascerem e sucesso reprodutivo), crescimento e padrões de alimentação dos filhotes em Tinhosa-de-barrete, Anous tenuirostris, na ilha de Aride, Seychelles, 1995–2002. Na maioria dos anos a postura ocorreu entre o fim de Maio e o fim de Junho. O sucesso de eclosão e o sucesso de sobrevivência das crias variaram significativamente entre anos, apresentando o sucesso de sobrevivência (2–92%) uma maior variação do que o sucesso de eclosão (28–91%). Uma produtividade inferior a 0,10 crias por casal reprodutor ocorreu em 25% dos anos. Em 2001, o volume dos ovos que eclodiram não diferiu significativamente do volume dos ovos que não eclodiram. O peso dos filhotes ao nascerem apresentou uma correlação significativa com o índice de volume dos ovos, mas não se obtiveram correlações entre o tamanho dos ovos e, a data de eclosão e a taxa de crescimento linear dos filhotes. Cerca de 40% dos filhotes de Tinhosa-de-barrete foram alimentados ao anoitecer. Os filhotes com idades entre 0–5 e 6–10 dias receberam significativamente menos alimento do que os filhotes mais velhos. Foram observadas variações diárias e estocásticas no sucesso de alimentação dos indivíduos. A comparação do presente estudo com estudos semelhantes, sugere que as crias de A. tenuirostris e de Sterna fuscata sejam mais resistentes a flutuações na disponibilidade de alimento do que as crias de Sterna dougallii. Isto indica que, em mares tropicais, uma menor taxa de crescimento e uma alimentação em zonas pelágicas são estratégias mais vantajosas do que uma taxa de crescimento rápida e alimentação em zonas costeiras.
