Background: Entomological surveillance is a vital component of vector control programmes as it helps to determine the geographical distribution, density, and species populations in areas at risk arboviral diseases. Moreover, calculating Stegomyia indices an integral Aedes which are high dengue. Methodology: In year 2018, entomological was carried out dengue endemic district Punjab identify diff...

An assessment of the stock status and historical changes in abundance Coilia mystus C. nasus Yangtze River Estuary, China, was carried out based on field surveys conducted 2019–2020 published length-frequency (L/F) data from earlier periods. These two species’ current past relative biomasses (B/BMSY) were estimated using a length-based Bayesian biomass estimation method (LBB). The LLB also thei...

Abstract. Paujiah E, Dhahiyat Y, Herawati T, Iskandar, Haryono, Zulfahmi I, Fahri. 2023. Length-weight relationships and condition factors of brackish water catfish, Mystus gulio (Hamilton, 1822) from three different estuaries, West Java, Indonesia. Biodiversitas 24: 2855-2864. This study investigated the biometric catfish (Mystus Hamilton collected estuaries in Cianjur District, Java Province,...

to relinquish its shell, allowing the attacker to evict it by pulling it out through the aperture; or the attacker may give up, and release the defender, without effecting an eviction. If the attacker is successful, it will perform the usual investigatory activities on the vacated shell and decide whether to occupy it permanently. During this process the evicted defender is left without a shell...

The species-group name Pagurus longitarsus was proposed by De Haan (1849: 211, pl. 50, fig. 3) for a species of hermit crab collected from Japan (see Yamaguchi & Baba 1993: 272, 273). Dana (1852b: 464) transferred Pagurus longitarsus to the genus Clibanarius Dana, 1852 (first established in Dana 1852a). Dana (1852b: 464) also suggested that Pagurus longitarsus De Haan, 1849, and Pagurus asper H...

Phylogenetic and geographic evidence suggest that many parthenogenetic organisms have evolved recently and have spread rapidly. These patterns play a critical role in our understanding of the relative merits of sexual versus asexual reproductive modes, yet their interpretation is often hampered by a lack of detail. Here we present a detailed phylogeographic study of a vertebrate parthenogen, th...

This study describes the daily activity in a simulated high tide situation of four species of hermit crabs (Pagurus criniticornis, Clibanarius antillensis, C. sclopetarius, and C. vittatus) that coexist in an intertidal flat in southeastern Brazil. Observations were done in two-hour intervals during two subsequent days (48 h) in three replicate pools with thirty crabs each. Among species (betwe...
