Species distribution modeling has been widely used to address questions related to ecology, biogeography and species conservation on global and regional scales. Here, we study palms (Arecaceae) in a tropical biodiversity hotspot (Thailand) using species distribution modeling to assess range-limiting factors and estimate distribution and diversity patterns based on a comprehensive compilation of occurrence records. We focused on palms as a model group due to their key-stone importance for ecosystem functioning and socio-economics. Different combinations of climatic, non-climatic environmental and spatial predictors were used. The most accurate models as indicated by the ‘area under the receiver operating characteristic curve’ (AUC) statistic were those that combined all predictors. The four strongest single predictors of palm species distributions were, in decreasing order of importance, 1) latitude, 2) precipitation of driest quarter, 3) annual precipitation, and 4) minimum temperature of the coldest month, suggesting rainfall patterns and latitudinal spatial constraints as the main range determinants. Overlaying the predicted distributions revealed that potential palm hotspots are situated in the provinces of Satun and Yala in southern Thailand where vast areas remain relatively open to the discovery of new palm records and perhaps even new species.

Barfod, A. 1988. Inflorescence morphology of some South American Anacardiaceae and the possible phylogenetic trends. - Nord. J. Bot. 8: 3–11. Copenhagen. ISSN 0107–055X. The inflorescences of 15 native and one introduced species of South American Anacardiaceae belonging to the genera Anacardium, Loxopterygium, Mangifera, Mauria, Mosquitoxylon, Schinus, Spondias, Tapirira and Toxicodendron are described according to the terminology of Troll and coworkers. The tribal divisions in the Anacardiaceae are supported by the inflorescence morphology. Tribe Spondia-deae has paniculate inflorescences whereas tribe Anacardieae and tribe Rhoeae both have thyrsoids. Toxicodendron is exceptional for the tribe Rhoeae having axillary panicles. Thyrosids are hypothesized derived from panicles by a two step process including neoteny and enriching by cymose branching.

Abstract Aim In the search for the ideal indicator taxon, fruit feeding butterflies have attracted increased focus for use in ecosystem assessments in the tropics. This study aims to shed light on the usability of fruit feeding butterflies in ecosystem assessments by comparing the effect of two different measures of ecosystem degradation on the fruit feeding butterfly community. Location The Interior biogeographical sub region of the Atlantic Forest, southern Brazil. Methods In this study, the impact of tree cover and urban area on the abundance, richness and diversity of fruit feeding butterflies were investigated. Tree cover was measured within 200 and 1000 m of each trap while urban area was just measured within 1000 m. This was accomplished with the use of standardized trapping methods and geospatial tools that allowed for spatial analysis of the area surrounding each trap. In contrast to the common approach, the grouping of sampling units where based on the specific research question addressed, thus enhancing the statistical significance of the results. Results Within 200 m a moderate amount of tree cover (~35–50% tree cover), were found to be positively correlated with all community metrics, while a high amount of tree cover within both 200 and 1000 m (~>50% tree cover) displayed a pronounced negative correlation with all community metrics. Any amount of urban area within 1000 m (~0–30% urban area) showed a pronounced negative correlation with all community metrics. Main conclusions Considering the effect of tree cover, several commonly used community metrics for fruit feeding butterflies were shown to respond contradictorily to what might be expected. However, regarding urban area, the fruit feeding butterfly community were found to respond as expected and was extraordinarily sensitive to disturbances. These results highlight the need to be critical in the choice of community metrics when utilizing fruit feeding butterflies as indicator taxon, while also demonstrating their sensitivity to habitat changes and potential in future habitat assessments. In addition, grouping trap data in accordance to specific research questions was found to yield very robust results, thus allowing for reduced survey costs in future studies.

ABSTRACT Sustainable management strategies for tropical forest ecosystems require a detailed understanding of the distribution of tropical forest species, limitations on distribution, as well as occurrence patterns in the absence of limitations. In the Americas, many tropical palms (Arecaceae) are locally abundant keystone species that provide a number of non-timber forest products. Here we focus on 10 such species (Aphandra natalia, Attalea phalerata, Euterpe oleracea, Iriartea deltoidea, Mauritia flexousa, Oenocarpus bataua, Phytele- phas aequatorialis, Phytelephas macrocarpa, and Phytelephas seemannii) found in western South America. This study aimed to determine: (i) what variables control potential species distribution, (ii) whether their distribution is spatially constrained and if so, (iii) how their potential ranges compare to their actual ranges. We built species distribution models using Maxent software with three groups of predictor vari- ables: C (climatic), N (non-climatic environmental), S (spatial), and combinations thereof: C, CN and CNS. The CNS predictor variable combination gave superior predictive ability based on median Area Under the Curve (AUC) values and was consistent with available range maps. In contrast, individual C and CN pre- dictor variables gave inferior AUC values and showed less similarity to range maps. We concluded that the CNS model that combined climatic, non-climatic, and spatial variables best represented the actual distribution of the 10 palm species, whereas C and CN models approached their potential distribution. Precipitation during the driest quarter and annual precipitation were the most important predictors of the potential distribution, whereas temperature of the coldest month, soil, and the Normalized Difference Vegetation Index (NDVI) were less important. We found that the actual distributions of palm species were spatially constrained, and that the spatial variables largely coincided with the dispersal barriers of the Andean Cordillera and past climatic fluctuations. The estimated potential range varied from nearly equal to the actual range, to up to 0.55 106 km2 (55.1 106 ha) larger than the actual range, depending on model, threshold settings, and species. We thus concluded that current palm resources in the forests of western South America have major potential for ecological expansion. These results are relevant to cur- rent palm management and resource conservation planning, as well as future strategies that will have to address climate change and increasing human disturbance

Abstract Tea-leaved willow (Salix phylicifolia L.) is native to the Faroe Islands where it has become rare due to intensive grazing and loss of suitable habitats. Based on analysis of amplified fragment length polymorphism (AFLP), we investigated the genetic structure of the extant populations of Faroese S. phylicifolia. Three genetically distinct populations were inferred by Bayesian clustering and several long distance connections were revealed. The patterns suggested imprints of historic introductions and poor gene flow between populations implying risks of drift and inbreeding. The results probably reflect a general issue for plant species on the Faroe Islands that are not well adapted to grazing. It was recommended that future efforts to protect Faroese S. phylicifolia should be focused on enrichment planting in protected areas at a central location on the Faroe Islands. Populations in protected areas may hopefully establish a viable gene pool to the support of peripheral populations in non-protected areas.

Abstract. Semi-arid West Africa has not been integrated into the afforestation/reforestation (AR) carbon market. Most projects implemented under the Clean Development Mechanism (CDM) have focused on carbon emission reductions from industry and energy consumption, whereas only few (only one in West Africa) have been certified for AR carbon sequestration. A proposed mechanism, Reducing Emissions from Deforestation and Degradation (REDD) to be discussed under COP15 aims to reduce emissions by conserving already existing ...

The flora of Tropical Asia is among the richest in the world, yet the actual diversity is estimated to be much higher than previously reported. Myanmar and Thailand are adjacent countries that together occupy more than the half the area of continental Tropical Asia. This geographic area is diverse ecologically, ranging from cool-temperate to tropical climates, and includes from coast, rainforests and high mountain elevations. An updated checklist of aquatic plants, which includes 78 species in 44 genera from 24 families, are presented based on floristic works. This number includes seven species, that have never been listed in the previous floras and checklists. The species (excluding non-indigenous taxa) were categorized by five geographic groups with the exception of to reflect the rich diversity of the countries ' floras.

Trees are rapidly disappearing from agrarian landscapes in many tropical countries, a severe problem to rural populations, who depend on wood and non-timber forest products (NTFP) for their livelihoods. The aim of this study was to determine tree density, diversity, biomass and carbon stock in farmlands in Senegal and to gain insight in the socio-economic determinants of the tree cover. An allometric model was developed to estimate the average above ground biomass (AGB) based on field investigations of 235.5 ha of agricultural fields. In total, 25 tree species were recorded with an average density of 1.6 tree ha-1 and a canopy cover of 1%. The AGB was 8.9 t. ha-1 corresponding to 4.45 t C ha-1. A single species, Cordyla pinnata, accounted for 50% of all the trees censured. Investigations of google Earth images showed considerable change in tree density during the investigated periods (2004, 2009 and 2013). The tree density decreased at the rate of 3% per year-1 from 2004-2009 and 6....
