Many animals build shelters to avoid predation, but some predators cope with these shelters to prey on them. To explore the behavioral interactions between shelter-building prey and their predators, we investigated the shelter defenses of t...
Fecal DNA Metabarcoding Analyses Imply Seasonally Opportunistic Feeding by the Japanese Marten, Martes melampus (Mammalia: Carnivora), in Southwestern Honshu Island, Japan [0.03%]

An understanding of the food web in forest ecosystems is essential to ensuring that society lives in harmony with nature; however, this can be challenging in areas mainly composed of forest environments, such as in the Japanese Archipelago....
Cnidopsins Characterized as Bistable Opsins From a Reef-Building Coral, Acropora tenuis [0.03%]
来自造礁石珊瑚Acropora tenuis的双稳态视黄醛色素（Cnidopsin）的鉴定

Yukiya Kakeyama et al.
Many cnidarian animals possess multiple opsins, including a type known as cnidopsin, which is found throughout the phylum Cnidaria and is divided into several subgroups. Previous studies have suggested that cnidopsins from jellyfish and cor...
Luticola nematophagus gen. et sp. nov. (Platyhelminthes: Rhabdocoela), a Terrestrial Ascophorine Flatworm from China and Its Biological Characteristics [0.03%]

Symbiosis is a key driver of evolution in life-history traits and reproductive strategies. Some symbiotic microorganisms manipulate host reproduction to enhance their own transmission, a phenomenon well studied in insects but less understoo...
Copy Number Variation in the Amylase Gene (AMY) in the Brown Bear (Ursus arctos), Based on Whole Genome Resequencing Data [0.03%]
基于全基因组重测序数据的棕熊淀粉酶基因（AMY）拷贝数变异分析
Naoko Kotani,Yu Endo,Naoki Osada et al.
Naoko Kotani et al.
Copy number variation (CNV) in gene loci in animals can be driven by adaption to the environment. The relationship between CNV in genes for amylase (AMY), which hydrolyzes starch, and dietary adaptation has been well studied. Copy number (C...
Co-Occurrence of Gastropods of the Genus Melanella (Mollusca: Eulimidae) Parasitizing the Black Sea Cucumber Holothuria leucospilota in Central Japan: Implications for Their Geographic Distribution and Parasitic Ecology [0.03%]
日本中部海域发现的黑色海参Holothuria leucospilota体内共生帽贝属Melanella物种共存：对帽贝属地理分布与寄生生态的意义分析

Snails of the family Eulimidae are parasites of echinoderms in all five extant classes. Despite long years of taxonomic research on Eulimidae in Japan, their local species richness remains to be investigated, and few studies have focused on...
Anemonefish Chromatophore Distribution and Organization Revealed by TEM Studies [0.03%]
透射电镜研究揭示的海葵鱼色素细胞分布与排列规律
Minato Miyake,Hsiao-Chian Chen,Pauline Salis et al.
Minato Miyake et al.
Anemonefish have a characteristic vertical white barred color pattern on an orange background made by a specific distribution of three types of pigment cells: melanophores, xanthophores, and iridophores. This color pattern is an interesting...
A Combined Genome-Wide SNP and mtDNA Approach Reveals the Phylogenetic Relationships of the Genus Chalcorana [0.03%]
基于SNP和线粒体全基因组的联合分析揭示类树蛙属系统的种间关系
Yuri Suzuki,Masafumi Matsui,Misbahul Munir et al.
Yuri Suzuki et al.
Using mitochondrial DNA and genome-wide SNP, phylogenetic relationships in Chalcorana were investigated. Phylogenetic analyses based on subregions of mtDNA found possible lineages of several cryptic species, but did not support the phylogen...
