Structural parameters of vegetation and quantification of aboveground biomass (AGB) are important in forest monitoring to understand the vital cycle of ecosystems. This activity is even more challenging in seasonally dry tropical forests such as the Caatinga biome. The feasibility of using the terrestrial laser scanner (TLS) to measure structural parameters of plants and estimate aboveground biomass was investigated as an alternative to traditional methods. The study was conducted in an area of caatinga vegetation in the municipality of Petrolina, PE, Brazil, where three experimental subareas were selected to obtain measurements, cutting, and weighing of plants with a soil surface level diameter greater than 2.5 cm, totaling 97 plants. Scans were performed with the light detection and ranging (LiDAR) technology using TLS to obtain a three-dimensional point cloud. The correlation coefficient (r2) for plant height measured in the field and obtained by TLS was 0.80. The measures of trunk diameter at soil surfacelevel and at heights of 40 and 130 cm showed r2of 0.79, 0.78, and 0.76, respectively. New exponential allometric equations were generated using input variables obtained in the field and point cloud TLS. These results demonstrate the feasibility and potential of using LiDAR-TLS in dry forests, such as caatinga vegetation. This emphasizes the need to deepen approaches, tools, and techniques using this technology throughout the year to detect variations due to senescence and, therefore, the carbon cycle MenosStructural parameters of vegetation and quantification of aboveground biomass (AGB) are important in forest monitoring to understand the vital cycle of ecosystems.

Abstract: The genus Lymania belongs to the Bromeliaceae family and currently has ten endemic species in Northeast Brazil, restricted to the Atlantic Forest domain, the vast majority threatened with extinction and with ornamental potential. Studies of pollen morphology and viability provide important information for taxonomic, reproductive, and species conservation. The aim of this study was to evaluate the morphology and viability of pollen grains of nine threatened Lymania species endemic to the Northeast region of Brazil and with ornamental potential. Pollen morphological characters were observed using Scanning Electron Microscopy (SEM) and Light Microscopy (LM). For the histochemical tests, two dyes were used: Alexander's solution and fluorescein diacetate, at three stages of floral development (pre-anthesis, anthesis, and post-anthesis). The pollen grains collected in these stages were germinated in vitro in two culture media (BM and SM). We observed that all species have monad pollen grains except for L. languida, with medium-sized grains arranged in tetrads, with oblate to suboblate shape, bilateral symmetry, triporate or biporate, semitectate or eutectate exine and reticulate-heterobrochate, psilate or perforate ornamentation. Most Lymania species showed higher germination percentage, pollen tube growth and viability when pollen was collected at anthesis. The SM culture medium and the pollen grain sampling at the floral anthesis stage were the most suitable for the Lymania species. Our investigation of the structure of pollen grains and pollen viability of these species provides important data for taxonomy, as well as for controlled crosses, obtaining seeds, or conservation trials, especially regarding threatened species.
