Abstract In the United Nations Decade on Ecosystem Restoration 1 , large knowledge gaps persist how to increase biodiversity and ecosystem functioning in cash crop-dominated tropical landscapes 2 . Here, we present findings from a large-scale, 5-year restoration experiment an oil palm landscape enriched with 52 tree islands, encompassing assessments of ten indicators 19 functioning. Overall, functioning, as well multidiversity multifunctionality, were higher islands compared conventionally...
Introduction High-throughput sequencing (HTS) provides an efficient and cost-effective way to generate large amounts of sequence data, providing a very powerful tool analyze biodiversity soil organisms. However, marker-based methods the resulting datasets come with range challenges disputes, including incomplete reference databases, controversial similarity thresholds for delimitating taxa, downstream compositional data analysis. Methods Here, we use HTS from nematode experiment explore...
In monoculture-dominated landscapes, recovering biodiversity is a priority, but effective restoration strategies have yet to be identified. this study, we experimentally tested passive and active recover taxonomic, phylogenetic, functional diversity of woody plants within 52 tree islands established in an oil palm landscape. Large higher initial planted catalyzed recovery, particularly at the landscape level. At local scale, results demonstrated that greater planting begets native recruits,...
Abstract Cross‐kingdom associations play a fundamental role in ecological processes. Yet our understanding of plant–fungal co‐occurrences tropical rainforests and the potential impacts land‐use change shaping species connections remain limited. By using amplicon sequencing on DNA from roots their associated fungal communities, we aim to understand impact rainforest transformation composition structure root–fungal networks human‐modified landscapes Sumatra, Indonesia. Each type supports...
DNA barcoding has been used as a universal tool for phylogenetic inferences and diversity assessments, especially in poorly studied species regions. The aim of this study was to contrast morphological taxonomy barcoding, using the three frequently markers matK, rbcL, trnL-F, assess efficiency identification dipterocarps Sumatra, Indonesia. chloroplast gene matK most polymorphic among these with an average interspecific genetic distance 0.020. results molecular data were mostly agreement...
Oscillations of periods with low and high temperatures during the Quaternary in northern hemisphere have influenced genetic composition birds Palearctic. During last glaciation, ending about 12,000 years ago, a wide area Palearctic was under lasting ice and, consequently, breeding sites for most bird species were not available. At same time, diversity habitats accessible subtropical tropical zones providing grounds refugia birds. As result long-term climatic oscillations, migration systems...
Abstract Background Intense conversion of tropical forests into agricultural systems contributes to habitat loss and the decline ecosystem functions. Plant-pollinator interactions buffer process forest fragmentation, ensuring gene flow across isolated patches by pollen transfer. In this study, we identified composition grains stored in pot-pollen stingless bees, Tetragonula laeviceps , via dual-locus DNA metabarcoding (ITS2 rbcL ) light microscopy, compared taxonomic coverage sampled...
Este estudo objetivou verificar a distribuição temporal e espacial de Eretmochelys imbricata (Linnaeus, 1766) aspectos sua biologia reprodutiva, tais como tempo incubação, sucesso reprodutivo, biometria das fêmeas, número ninhos fecundidade. Os dados foram coletados 2007 2010 nas praias Muro Alto, Cupe, Merepe, Porto Galinhas Maracaípe, todas elas localizadas no município do Ipojuca, estado Pernambuco, Brasil. Foram analisados comparativamente parâmetros relativos à reprodutiva áreas...
Eretmochelys imbricata Linneus 1766 was the subject of trade due to egg collection and consumption flesh females, being fishery one main impacts towards coastal area. The pathogens are also worrying factors mortality sea turtles especially those caused by fungi; these can cause death embryos cutaneous mycoses. This study aimed investigate mycoflora isolated from soil, eggshells stillbirths E. in three beaches Ipojuca (Brazil). We recorded data on reproductive biology species after incubation...
We conducted a large‐scale phylogenetic and biogeographical inference of the Poliptila gnatcatchers investigated evolutionary history two closely related neotropical bird species linked to open habitats, Polioptila dumicola plumbea . A Bayesian was employed based on NADH subunit 2 gene reconstruct relationship gnatcatchers, ancestral area reconstructions were estimated using BioGeoBEARS. For phylogeographic analysis, we analyzed mitochondrial genes, cytochrome b ND2, 102 individuals from P....
We focus on reconstructing a spatiotemporal scenario of diversification widespread South American species, the Pectoral Sparrow Arremon taciturnus (Aves: Passerellidae). This species is widely distributed in both humid and dry forests America therefore provides an interesting model for understanding connection between different biomes America. examined nucleotide sequences mitochondrial genes Cytochrome b (cyt‐b) NADH subunit 2 (ND2) from 107 specimens, one nuclear marker (intron 7...
The knowledge of natural history the Brazilian species turtles is still insipient because most information about these animals are restricted to a few records occurrence, which in general sparse literature or even museums. paucity prevents broader approaches on various ecological and evolutionary aspects, primordial for conservation planning management group. large geographical extent, environmental complexity, degradation biomes Northeast Brazil make systematization biological data from...
While the need for biodiversity research is growing, paradoxically, global taxonomical expertise decreasing as a result of neglected funding young academics in taxonomy. Non-destructive approaches DNA barcoding are necessary more efficient use this dwindling to fill gaps, and identify incorrect entries sequence databases like BOLD or GenBank. They because morphological re-examination species vouchers still possible post-DNA barcoding. Diptera with comprehensive representation consideration...
Sea turtle hatchlings, in natural abiotic conditions, emerge from their nests at night and go directly to the sea, following moonlight's reflection ocean. Increased human activities such as tourism artificial lights on coasts, however, have interfered with ability of sea neonates find correct destination, negatively affecting survival rates. Here we endeavored assess influence hatchlings Eretmochelys imbricata (Linnaeus, 1766) south coast state Pernambuco, Brazil. To that end, 10 experiments...
Abstract Optimizing restoration outcomes is crucial for enhancing multifaceted diversity, resilience, and ecosystem functioning in monoculture-dominated landscapes globally. Here, we experimentally tested the performance of passive active strategies to recover taxonomic, phylogenetic, functional diversity by establishing 52 tree islands an oil palm landscape. Tree via natural regeneration was shaped local rather than landscape properties, with planted species island size driving higher...
Molecular biodiversity surveys have been increasingly applied in hyperdiverse tropical regions as an efficient tool for rapid species assessment of partially undiscovered fauna and flora. This is done by overcoming shortfalls knowledge or availability reproductive structures during the sampling period, which often represents a bottleneck accurate specimens’ identification. DNA sequencing technology intensifying discovery, combination with morphological identification, has filling gaps...

Abstract DNA barcoding is a popular tool for species identification of insect samples, with important applications plant protection. However, Barcode Life Database queries related to tachinid samples can produce ambiguous results due contradictory assignments. Therefore, we applied Bayesian phylogenetic inference 811 Tachina Meigen, 1803 COI-5P sequences containing all assignments Index Numbers. Based on assignment, the assemble by automatic partitioning (ASAP) analysis, MonoPhy test and...
