Ecological indicators for qualitative assessment of Ojarud River: A case study. [PDF]
The results of this study exposed a sizable alteration in the diversity and abundance of macro‐invertebrate from the sensitive families to resistant and tolerant taxa under the contamination stress resulting from the point source pollution in the Ojarud River.

Multi-marker DNA metabarcoding reveals spatial and sexual variation in the diet of a scarce woodland bird. [PDF]
Hawfinch (Coccothraustes coccothraustes) have been declining in the UK since the 1970s. Using DNA metabarcoding, we wanted to increase ecological knowledge associated with Hawfinch, to aid their recovery. We found 49 and 90 prey taxa in the diet, which can improve our knowledge of why Hawfinch persist within certain areas of the UK. Abstract Avian diet

Orally Administered Edible Snail Extract Powder Enhances Skin Hydration via Hyaluronic Acid Synthesis and Barrier Gene Modulation in SKH-1 Hairless Mice. [PDF]
Immunohistochemical staining of dorsal skin tissues for HAS2, HYAL1, and TGF‐β1. Oral administration of SEP increased the expression of HAS2 and TGF‐β1 in a dose‐dependent manner, while reducing HYAL1 expression. These findings indicate that SEP promotes hyaluronic acid synthesis and extracellular matrix remodeling. The results support the moisturizing

Life history and population ecology of Radix swinhoei (Lymnaeidae) in nearshore regions of a hypereutrophic plateau lake. [PDF]
The life history traits (life span and growth), annual secondary production, and population size structure of Asia widespread pulmonate Radix swinhoei were carefully and systematically examined across 1 year in nearshore regions of a hypereutrophic plateau lake, Lake Dianchi. The maximum potential life span of R.

Spatio-Temporal Variation in Diet Among Age and Sex Cohorts of a Model Generalist Bird Species, the Great Tit <i>Parus major</i>: New Insights Revealed by DNA Metabarcoding. [PDF]
Identifying the sources of intraspecific dietary variation is central to understanding how populations adapt to environmental variation, and yet these sources are poorly understood in a key model species in avian ecology, the great tit. Here we use DNA metabarcoding to describe the diet of great tits at an unprecedented level of detail and reveal ...

Abundance, Distribution, and Diversity of Freshwater Snail and Prevalences of Their Infection by Cercaria of Fasciola gigantica and Schistosoma spp at Mayo-Vreck River, Far North Region of Cameroon. [PDF]
Malacological and parasitological studies were conducted from April 2020 to March 2021 to determine the abundance and distribution of molluscs and cercariae of Schistosoma spp and Fasciola gigantica. Collected molluscs are exposed to strong light to induce cercarial release. Mollusc densities were higher at station 1 (Gamak) than in station 8 (Patakai),

Molecular assessment of food web dynamics identifies critical periods for managing resilience in biological pest control. [PDF]
Abstract Food webs are not static over time, but our knowledge of their dynamics is extremely scarce due to methodological challenges. In turn, this significantly limits our ability to mechanistically understand the temporal changes that trophic networks annually undergo.

Target‐capture probes for phylogenomics of the Caenogastropoda
Abstract Target‐capture approaches have facilitated a rapid growth in the field of phylogenomics but few probe sets exist for molluscs, an exceptionally rich phylum with unparalleled ecological and morphological diversity. We designed and tested the first universal probe set using Phyluce to capture ultraconserved elements (UCEs) and exon loci from the

Haldane's rule: when hybrids from one sex are absent, rare or sterile, that sex is always the heterogametic sex. Abstract Haldane's rule is one of the ‘two rules of speciation’. It states that if one sex is ‘absent, rare or sterile’ in a hybrid population, then that sex will be heterogametic.
