  Comparing the Diversity of Nematodes and other Microbial Metazoa across Different Habitats in the Shipley-Skinner Reserve, Descrição: Our goal is to carry out a baseline study of microbial metazoan soil communities within Shipley-Skinner Reserve, with an emphasis on free-living nematodes. We will assess metazoan diversity and community assemblages across different sites in the reserve, including dominant habitat types (e.g., coastal Sage Scrub, non-native grasslands, and chaparral) as well as other distinct but smaller scale habitats (e.g., coast live oak woodland, southern willow scrub and live oak, and cottonwood willow riparian forests). Nematodes will be identified based on morphological taxonomy (i.e., light microscopy) and molecular (i.e., single-specimen DNA barcoding and environmental sequencing) approaches; nematode abundance and diversity will be compared among different habitats, so that associations between nematode communities and habitat types can be determined. Since environmental sequencing approaches typically use PCR primers that target a broad range of taxa (using conserved primer regions that target the 18S rRNA gene), we will be able to assess diversity and community patterns in >20 metazoan phyla in addition to nematodes. Owing to the number of distinct microhabitats in the Shipley-Skinner Reserve, varying with elevation, moisture, vegetation, and soil type, we expect to observe high levels of metazoan diversity including endemic species, particularly for soil nematodes.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Tiago José Pereira - Integrante / Holly M.

  Assessing benthic meiofaunal community structure in the Alaskan Arctic: A high-throughput DNA sequencing approach, Descrição: We conducted the first baseline surveys of benthic metazoan meiofauna in the Chukchi and Beaufort seas using high-throughput gene sequencing of environmental DNA extracts from sediment samples. Despite their importance to sediment biogeochemical processes and marine food webs, meiofauna are notoriously difficult to characterize because components of the fauna are poorly preserved in sediment samples, lack obvious morphological features, and are extremely small in size (~45 m ? 1 mm); thus, they have been largely ignored in many regions including the Arctic. We demonstrate the utility of DNA-based approaches as an alternative to the standard microscopy techniques for rapid assessment of meiofaunal community structure. We used amplicon sequencing of the 18S rRNA gene to provide a baseline assessment of metazoan eukaryotic community structure in sediments from 120 locations distributed throughout the NE Chukchi and US and Canadian Beaufort Sea shelf and slope, and generated a morphology-based inventory of the Nematoda at a subset of these sites based on expert taxonomic identifications. Morphology data is compared with the results of 18S amplicon surveys to determine that similar information is obtained through both approaches. Moreover, the Nematoda 18S dataset is correlated with the full Metazoa 18S dataset, suggesting this group may reflect important environmental drivers governing the assembly of whole communities in this region. This dataset was very recently finalized and is still undergoing analysis and synthesis. The results presented here offer a broad overview of the taxonomic composition of the sequence dataset, and examine broad-scale regional patterns in community structure.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Tiago José Pereira - Integrante / Taruna Schuelke - Integrante / Holly M.

  ARTS: Overcoming the nematode taxonomic impediment through integration of novel tools for species discovery and phylogeny: Cephaloboidea as a case-study, Descrição: Our existence depends on soil, soil organisms, and their processes. Yet nematodes, arguably the most abundant and diverse metazoans in soil, remain its least known component. Most nematode species are undescribed and there is a paucity of biodiversity specialists to address the challenge. Considering these circumstances, new approaches and methodologies are needed to overcome the taxonomic impediment. To address these broad goals we focus on a model system of the widespread, diverse and complex Cephaloboidea, a group for which we have developed considerable experience through NSF PEET research. A key objective herein is to develop and implement a novel, efficient and reliable molecular-based approach for nematode species discovery (molecular prospecting) through a reverse-taxonomy (RT) approach. RT involves obtaining high-resolution digital images and nucleotide sequence identifiers for individual specimens, providing linkages that permit reciprocal verification of potential species via morphology and DNA sequences. The increased efficiency of RT for discovering potential species can overcome one major impediment in nematode taxonomy. Taxa discovered by molecular prospecting will serve as the basis for testing hypotheses of species (species delimitation), using multiple genetic loci and comparative morphology to evaluate lineage independence. Challenges of minute nematode morphology are addressed with novel, relatively simpler approaches for broad application.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Tiago José Pereira - Coordenador / Mundo-Ocampo, Manuel - Integrante / CARES, JUVENIL E. - Integrante / Steve Nadler - Integrante / Mirayana Marecelino Barros - Integrante.

  Diversity and systematics of tylenchid nematodes (Tylenchina) in the Anza-Borrego State Park, Descrição: Our goal is to inventory nematode diversity on Anza-Borrego State Park by sampling soil nematodes at different sites (still to be defined but emphasizing diverse habitats) and recording morphological and molecular data; vouchers will be deposited in the UCR Nematode Collection (UCRNC). Although all diversity will be recorded, we will focus mostly on nematodes from the suborder Tylenchina. Results will allow comparison of current nematode diversity with previous records for this area in the UCRNC (taxonomic museum). In addition, this study will increase the baseline for understanding the nematode diversity in the Anza-Borrego State Park as a starting point for future biodiversity studies which can monitor ecological disturbance such as climate change (globally) and fires (locally). Undescribed new species from this study are anticipated based on previous collections and these will be described and published. Material from the collection will also be incorporated in ongoing phylogenetic studies on Tylenchina.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Tiago José Pereira - Coordenador / Manuel Mundo-Ocampo - Integrante / BALDWIN, JAMES G. - Integrante.

  A preliminary assessment of terrestrial nematode diversity from undisturbed ecosystems of Baja California, northwestern Mexico, Descrição: As a seed project with great promise for Federal funding, we propose three field trips in different sites in Baja California, Mexico and with two goals: 1) to collect soil nematodes and 2) to explore the implications of these collections for potential collaborations with scientists at CICESE in Ensenada. The key objective is to develop preliminary data on the fruitfulness of this region for collecting, from relatively undisturbed habitats, soil nematodes (e.g. Tylenchina) otherwise not available for evolutionary, phylogenetic and taxonomic studies. This study will provide insight on soil nematode diversity in these unique Mexican ecosystems that have thus far been largely unstudied in this regard.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Doutorado: (1) . , Integrantes: Tiago José Pereira - Integrante / Manuel Mundo-Ocampo - Coordenador / BALDWIN, JAMES G. - Integrante.

  PEET: Training the next generation of nematode taxonomists: applying the tools of modern monography across free-living and parasitic Tylenchina, Descrição: The great significance, abundance, genetic diversity and key role of the Phylum Nematoda in basic biology, biodiversity, ecosystems, agriculture, veterinary science and medicine contrasts starkly with the embryonic state of nematode taxonomy and the paucity of taxonomic specialists. The primary objective of this PEET is to address this gap by leveraging complementary strengths of the Departments of Nematology at UCR and UCD, including two major taxonomic collections, to provide professional training in morphological and molecular nematode systematics. Building upon our previous PEET successes we will develop a much-needed monograph of the monophyletic suborder Tylenchina (sensu De Ley and Blaxter, 2002: composed of infraorders Tylenchomorpha, Cephalobomorpha, Panagrolaimomorpha and Drilonematomorpha), which includes a range of morphologically disparate free-living microbivores as well as plant and animal parasitic taxa.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Doutorado: (1) . , Integrantes: Tiago José Pereira - Integrante / Mundo-Ocampo, Manuel - Integrante / BALDWIN, JAMES G. - Coordenador / Oleksandr Holovachov - Integrante / Steve Nadler - Integrante / Paul de Ley - Integrante / Irma De Ley - Integrante.
