The objectives this study focus on understanding structure, connectivity, responses ENs construction land, crucial for maintaining sustainability. Employing circuit theory, Minimum Cumulative Resistance (MCR) model, complex network analysis methods, constructed evolution...

Abstract Botanical molluscicides for controlling the invasive snail Pomacea canaliculata have attracted worldwide attention because of their cost and environmental friendliness. Aqueous extracts from discarded tobacco leaf ( Nicotiana tobacum ) were evaluated molluscicidal activity against different-sized P. under laboratory conditions. The results showed that over 90% snails died in 1 g/L extract within 4 days, survival was inversely proportional to size, concentration length exposure time....

The present study aimed to verify the labelling compliance, accuracy of trade names, and molecularly identify 74 pre-packaged grilled fish products purchased online on Taobao, largest e-commerce platform in China. compliance was assessed light Chinese standard GB7718-2011 for foods. Products identification performed by DNA barcoding targeting two mitochondrial genes (COI cytb) while, name, analysing results obtained using 'common name search tool' available FAO FishBase portal. reported...

Pomacea canaliculata is native to South America and has become a widely distributed agricultural environmental pest in southern China. Previous studies have primarily focused on the tolerance of P. various factors, compared non-native invasive with natives or non-invasive congeners. However, there been no research concentrated variation innate growth reproductive characteristics between its invaded areas. To address this gap, we conducted first comparison experiment from their area...

Surimi-based products (SBP), such as fish cakes, being processed generally composed by mixture of species, are particularly susceptible to species substitution fraud. In this study, 56 cakes (FCP) purchased on the Chinese e-commerce were analyzed using DNA barcoding (COI and cytb) identify dominant compare it trade name reported label. Part them also metabarcoding (16S rRNA), including positive negative control samples, better evaluate their composition. Overall, 12 different names labels,...

The behavior of invasive species under predation risk has been studied extensively, but their growth and reproductive responses have rarely investigated. We conducted experiments with juveniles adults the freshwater snail Pomacea canaliculata, we observed changes in reproduction response to from a caged predator (Trachemys scripta elegans). P. canaliculata produced eggs earlier presence predators injured conspecifics compared control group (no risk), although total number egg masses laid by...

The apple snails Pomacea canaliculata, diffusa and maculate (Gastropoda: Caenogastropoda: Ampullariidae) are invasive pests causing massive economic losses ecological damage. We sequenced characterized the complete mitochondrial genomes of these to conduct phylogenetic analyses based on comparisons with protein coding sequences 47 Caenogastropoda species. gene arrangements, distribution content were canonically identical consistent typical Mollusca except for tRNA-Gln absent in P. diffusa....

All them are encoded on heavy strand except 7 genes light strand. Overall nucleotide compositions 44.51% A, 26.74% T, 20.48% C and 8.28% G. start with ATG initiation codon ATP6 ATA ND4 TTG, types termination codons TAA (ATP6, ND2, COX1, COX2, ATP8, ND1, ND6, Cytb, COX3, ND4) TAG (ND4L, ND5, ND3). There 29 intergenic...

Abstract Background Despite the medical importance of mosquitoes genus Anopheles in transmission malaria and other human diseases, its phylogenetic relationships are not settled, characteristics mitochondrial genome (mitogenome) thoroughly understood. Methods The present study sequenced analyzed complete mitogenomes An. peditaeniatus nitidus , investigated characteristics, inferred 76 spp. Results 15,416 15,418 bp long, respectively, both include 13 PCGs, 22 tRNAs, two tRNAs one control...

Sushi and sashimi are seafood products that widely consumed around the world, including also China. Currently they sold through alternative channels such as e-commerce. In this study, 60 Japanese Seafood Products (JSPs) suitable for sushi preparations (fish meat or roe), purchased in Chinese e-commerce, were analyzed. Initially, trade name accuracy compliance of labeling with standard pre-packaged food evaluated. Then, species composition JSPs was assessed by molecular analysis two genetic...

Sinamma Lin & Li, 2014 is a small tetrablemmid genus distributed in China, with three currently known species: oxycera from Guangxi Zhuang Autonomous Region and S. quadrata Tong 2022 yingae Guangdong Province. While examining spider specimens obtained by sifting leaf litter Danxiashan National Nature Reserve Province of we discovered new species the , danxia sp. nov. which described here.

The golden apple snail Pomacea canaliculata is invasive in South China and poses serious harm to agricultural production aquatic ecosystems. In the present study, we investigated predatory potential of spotted green pufferfish Tetraodon nigroviridis (50 mm body length) on snails various sizes fresh brackish water (4.5 ppt salinity). survival damage rates 50 were estimated at 1, 3, 5 7 days. rate snails, including 10 adult (20–35 shell height), decreased less than 25% presence pufferfish,...

Abstract Pomacea canaliculata , a freshwater snail from South America, has rapidly established natural populations south to north subtropical region in China, since its original introductions the 1980s. Low temperature winter is limiting factor geographic expansion and successfully establishment for apple populations. There have been some studies on population level of low tolerance P. yet little quantified about life‐history traits responses cold temperatures. Whether these vary with...

Invasive species have had substantial impacts on global mangrove forests. Apple snails (Pomacea canaliculata) invaded forests in China. To clarify the potential detritivorous diet of P. canaliculata, growth and feeding indicators invasive juvenile collected from mangroves Guangzhou, China, were studied using decaying leaf litter five species, including Acanthus ilicifolius, Acrostichum aureum, Kandelia candel, Aegiceras corniculatum, Sonneratia apetala. The survival ratio specific rate...

As the frequency of droughts increases with climate change, tolerance aquatic organisms to abiotic stressors will become critical determinants survival. Pomacea canaliculata has a widely distributed agricultural and environmental pest in southern China. To evaluate their adaptation under drought condition, survival, feeding, behavior, antioxidant system changes female male P. were investigated during stress rewatering process through an indoor simulation experiment. The results showed that...

Morphological traits measurement still plays a key role in description, identification, classification and phylogenetics of species. However, the traditional morphological method is inefficient often destructive to studied organism. In this study, we propose test an X-ray-based technique for non-destructive studies fish. We use approach attempt discriminate four species from genus Megalobrama on basis their morphometric meristic traits. The results showed that there were significant...

After excision of shell from Pomacea canaliculata, survival rates, repair process, haemocyte response, and calcium content were observed quantified for three weeks. The following experimental treatments used: black-colored individuals with large (BL-group) or small (BS-group) heights, yellow-colored (YL-group) (YS-group) heights. rates in BL-, YL-, BS-, YS-groups after making partial excisions snail shells were, respectively, 93.59, 94.87, 92.31, 96.15%. Freshly regenerated could be seen at...
