Impact of Forest Fragmentation and Associated Edge Effects on Tropical Forest Biodiversity in North West Madagascar, Assessed via Ecoacoustics

Animal Conservation, Volume 29, Issue 3, Page 249-260, June 2026.
Deforestation in the tropics is a major threat to forest‐specialist animals, many of which are already threatened with extinction. We assessed how forest fragmentation and its associated edge‐effects impact animal biodiversity in Northwest Madagascar using soundscape analysis and acoustic indices.

Comparison of DNA extraction kits for PCR-DGGE analysis of human intestinal microbial communities from fecal specimens

Nutrition Journal, 2010
Background The influence of diet on intestinal microflora has been investigated mainly using conventional microbiological approaches. Although these studies have advanced knowledge on human intestinal microflora, it is imperative that new methods are ...

Changes in the microbiome and metabolome in captive red kangaroos (Osphranter rufus) affected by macropod progressive periodontal disease

Australian Veterinary Journal, Volume 104, Issue 6, Page 365-375, June 2026.
Macropod progressive periodontal disease (MPPD) is a severe oral condition frequently observed in captive macropods, particularly red kangaroos (Osphranter rufus), yet its underlying biological features remain poorly understood. In this exploratory descriptive study, we investigated oral and fecal microbiomes and metabolomic profiles in captive red ...

The Elusive Fraction of Marine Plankton Diversity: Size, Abundance and Taxonomic Composition of 0.2 μm‐Filterable Prokaryotes Across Three Contrasting Coastal Environments

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The existence of prokaryotes escaping filtration through 0.2‐μm filters has been known for decades. Such ‘filterable’ prokaryotes (hereafter ‘FP’) might include true ultra‐small groups (i.e., ultramicrobacteria), but also cells that miniaturize temporally as a physiological strategy to persist under unfavourable conditions, representing a ...

Comparing Freshwater eDNA With Conventional Survey Methods to Detect Vertebrate Biodiversity in a Malagasy Tropical Rainforest

Environmental DNA, Volume 8, Issue 3, May–June 2026.
This study compares the efficacy of conventional surveys of vertebrate taxa to eDNA metabarcoding of freshwater samples from a tropical rainforest ecosystem in the Makira Forest Protected Area (MFPA), Madagascar. We demonstrate high but taxa‐varying efficacy of eDNA metabarcoding detections, reinforcing its use as a complementary biodiversity survey ...

Cell Lysis Method Affects Assessment of Microbial Diversity Based on Ribotyping Analysis

Microbiology Indonesia, 2010
The microbial community in Kawah Hujan, Kamojang, West Java, Indonesia, was analyzed using 16S-rRNA-gene-sequencing combining with denaturing-gradient-gel electrophoresis (DGGE) technique.

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

Journal of Integrative Plant Biology, Volume 68, Issue 5, Page 1399-1420, May 2026.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

Mutations in the low density lipoprotein receptor gene of familial hypercholesterolemic patients detected by denaturing gradient gel electrophoresis and direct sequencing.

Journal of Lipid Research, 1995
Familial hypercholesterolemia (FH) results from mutations in the low density lipoprotein receptor (LDLR) gene. We applied denaturing gradient gel electrophoresis (DGGE) to screen for sequence variations in the coding and splice site consensus sequences ...

DGGE-based detection method for Quahog Parasite Unknown (QPX) [PDF]

Diseases of Aquatic Organisms, 2006
Quahog Parasite Unknown (QPX) is a significant cause of hard clam Mercenaria mercenaria mortality along the northeast coast of the United States. It infects both wild and cultured clams, often annually in plots that are heavily farmed. Subclinically infected clams can be identified by histological examination of the mantle tissue, but there is ...
