Effects of weir‐induced habitat fragmentation on the diversity and community composition of benthic macroinvertebrates in an agricultural stream

open access: yesEntomological Research, Volume 54, Issue 9, September 2024.
Abstract This research delves into the effects of weir‐induced habitat fragmentation on the diversity and structure of benthic macroinvertebrate communities in Topyeong Stream in the Republic of Korea. Through comprehensive zonation, environmental assessments and analyses of macroinvertebrate populations, the study brings to light the significant ...

Marine sediment infauna‐based environmental assessment using metabarcoding identifies potential impact indicator species

open access: yesEnvironmental DNA, Volume 6, Issue 3, May–June 2024.
Intertidal infaunal community data are obtained via: (1) morphological identification of macroinvertebrates from sediment cores, (2) cytochrome c oxidase subunit I (COI) DNA metabarcoding of the same pooled macroinvertebrate specimens, and (3) 18S ribosomal RNA (18S) DNA metabarcoding of benthic meiofauna from small volume sediment surface scrapes.

DNA metabarcoding reveals seasonal changes in diet composition across four arthropod‐eating lizard species (Phrynosomatidae: Sceloporus)

open access: yesIntegrative Zoology, Volume 19, Issue 3, Page 480-495, May 2024.
By applying DNA metabarcoding approach, we explored the seasonal diet variation among four Sceloporus lizard species (S. aeneus, S. bicanthalis, S. grammicus, and S. spinosus) inhabiting a mountainous region in central Mexico. Our results demonstrated that these species are generalist predators feeding on different arthropod orders such as Coleoptera ...

Diet in phenotypically divergent sympatric species of African weakly electric fish (genus: Campylomormyrus)—A hybrid capture/HTS metabarcoding approach

open access: yesMolecular Ecology, Volume 33, Issue 4, February 2024.
Abstract Ecological speciation within the mormyrid genus Campylomormyrus resulted in sympatric species exhibiting divergence in their feeding apparatus and electric organ discharge (EOD). This study documents the overall diet of the genus Campylomormyrus and examines the hypothesis that the Campylomormyrus radiation is caused by adaptation to different

Is There Good Simulation Basic Training for End-To-Side Vascular Microanastomoses? [PDF]

open access: yes, 2018
Background: Microvascular anastomosis is the cornerstone of free tissue transfers. Irrespective of the microsurgical technique that one seeks to integrate or improve, the time commitment in the laboratory is significant. After extensive previous training
