AfriSAR: Rainforest Canopy Height Derived from PolInSAR and Lidar Data, Gabon
This dataset provides estimates of forest canopy height and canopy height uncertainty for study areas in the Pongara National Park and the Lope National Park, Gabon. Two canopy height products are included: 1) Canopy height was derived from multi-baseline Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) data using an inversion of the random volume over ground (RVoG) model and Kapok, an open source Python library. 2) Canopy height was derived from a fusion of PolInSAR and Land, Vegetation, and Ice Sensor (LVIS) Lidar data. This dataset also includes various intermediate parameters of the PolInSAR data (including radar backscatter, coherence, and viewing and terrain geometry) which provide additional insight into the input data used to invert the RVoG model and accuracy of the canopy height estimates. The AfriSAR campaign was flown from 2016-02-27 to 2016-03-08. AfriSAR data were collected by NASA, in collaboration with the European Space Agency (ESA) and the Gabonese Space Agency.

Rainforest and cloud forest Scolytodes (Curculionidae, Scolytinae, Hexacolini) from the Arthropods of La Selva inventory in Costa Rica: new species, new synonymy, new records
<p>Quantitative collecting efforts over the last several decades in Costa Rica have resulted in many new species of insects. The Arthropods of La Selva projects included collecting from a typical lowland Neotropical forest and up an altitudinal transect, and has provided many valuable samples of insects, spiders and mites potentially new to science. We describe 18 new species in the bark beetle genus <em>Scolytodes</em> Ferrari, 1867, 14 of which were collected during this project: <em>S. angulus</em> Jordal & Kirkendall, <strong>sp. nov</strong>., <em>S. sufflatus</em> Jordal & Kirkendall, <strong>sp. nov</strong>., <em>S. squamatifrons</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. comosus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. spatulatus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. seriatus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. profundus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. catinus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. fimbriatus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. sulcifrons</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. planifrons</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. porosus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. mundus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. callosus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. parvipilus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. plenus</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, <em>S. niger</em> Jordal & Kirkendall, <strong>sp. nov.</strong>, and <em>S. simplex</em> Jordal & Kirkendall, <strong>sp. nov.</strong> One species, <em>Scolytodes minutissimus</em> Schedl, 1952, is redescribed to match the holotype. We give new Costa Rica records for <em>S. costabilis</em> Wood, 1974, which is the correct name for <em>S. obesus</em> Wood, 1975 (<strong>syn. nov</strong>.). We report Costa Rica as a new country record for six species: <em>Scolytodes clusiacolens</em> Wood, 1967, <em>S. crinalis</em> Wood, 1978, <em>S. culcitatus</em> (Blandford, 1897), <em>S. libidus</em> Wood, 1978, <em>S. reticulatus</em> (Wood, 1961), and <em>S. spadix</em> (Blackman, 1943). From a closely related genus, we provide the first record for Central America (and only the second collection) of <em>Pycnarthrum fulgidum</em> Wood, 1977.</p>
Data from: Clade-age-dependent diversification under high species turnover shapes species richness disparities among tropical rainforest lineages of Bulbophyllum (Orchidaceae)
Background: Tropical rainforests (TRFs) harbour almost half of the world's vascular plant species diversity while covering only about 6–7% of land. However, why species richness varies amongst the Earth's major TRF regions remains poorly understood. Here we investigate the evolutionary processes shaping continental species richness disparities of the pantropical, epiphytic and mostly TRF-dwelling orchid genus Bulbophyllum (c. 1,948 spp. in total; Asia-Pacific region: c. 1,564 spp.; Madagascar: 210; Africa: 80; Neotropics: 94) using diversification analyses based on a time-calibrated molecular phylogeny, coupled with ecological niche modelling (ENM) of geographic distributions under present and past (Last Glacial Maximum) conditions. Results: Our results suggest an early-to-late Miocene scenario of 'out-of-Asia-Pacific' origin and progressive, dispersal-mediated diversification in Madagascar, Africa and the Neotropics, respectively. Species richness disparities amongst these four TRF lineages are best explained by a time-for-speciation effect rather than differences in net diversification or diversity-dependent diversification due to present or past spatial-bioclimatic limits. All four lineages of experienced dramatic range expansions during the LGM, which conflicts with the common notion that TRFs mostly fragmented/contracted during glacial periods. Conclusions: Most species of at least the Madagascan, African and Neotropical lineages originated during the Quaternary. Their diversification under high species turnover (i.e. high rates of speciation and extinction) might relate to climate-induced range fluctuations during this time period combined with various intrinsic features commonly invoked to foster rapid population turnover in tropical orchids (e.g., epiphytism, specialization on pollinators and mycorrhizal fungi, dispersal by wind). Further (e.g., phylogenomic and ecological) research within each Bulbophyllum lineage but also other pantropical TRF taxa is required to provide a better understanding of how evolutionary processes as well as past and current environmental conditions drive tropical biodiversity and account for regional differences in species richness patterns on a global scale.
Data from: Intra-specific relatedness, spatial clustering and reduced demographic performance in tropical rainforest trees
Intra-specific negative density dependence promotes species coexistence by regulating population sizes. Patterns consistent with such density dependence are frequently reported in diverse tropical tree communities. Empirical evidence demonstrating whether intra-specific variation is related to these patterns, however, is lacking. The present study addresses this important knowledge gap by genotyping all individuals of a tropical tree in a long-term forest dynamics plot in tropical China. We show that related individuals are often spatially clustered, but having closely related neighbors reduces the growth performance of focal trees. We infer from the evidence, that dispersal limitation and negative density dependence are operating simultaneously to impact the spatial distributions of genotypes in a natural population. Furthermore, dispersal limitation decreases local intra-specific genetic diversity and increases negative density dependence thereby promoting niche differences and species co-existence as predicted by theory.
