Comparing five species of pipefish, egg size was significantly larger in species with brood pouches (Syngnathus typhle, Syngnathus acus and Syngnathus rostellatus) than in species without brood pouches (Entelurus aequoreus and Nerophis ophidion). Egg size correlated positively with female body size in species with brood pouches, but was similar across female sizes in the species lacking pouches...
In this research, gut lengths and numerical occurrence of gut contents (NO%) of Syngnathus acus, Syngnathus typhle and Nerophis ophidion were examined. The specimens were captured with beach seine net in different habitats (vegetated and sandy-vegetated etc.) at the coasts of Aegean Sea between 2006-and 2008. The zooplanktonic preys were mostly consumed by Syngnathus acus and Nerophis ophidion,...
نی ماهی سیاه راه راهِ دریای خزر (syngnathus nigrolinatus caspius)، تاکنون تنها گونه ثبت شده از خانواده syngnathidae در دریای خزر می باشد. در این تحقیق 50 قطعه نی ماهی در آب لب شور حوضه خلیج گرگان (جنوب شرقی دریای خزر) صید و مورد ارزیابی قرار گرفته شد. 21 فاکتور ریخت سنجی و 6 فاکتور شمارشی بررسی و پارامتر های پویایی شناسی شامل طول بی نهایت، سن صفر، نرخ رشد لحظه ای و فاکتور وضعیت جمعیت های این ماه...
This article documents the addition of 512 microsatellite marker loci and nine pairs of Single Nucleotide Polymorphism (SNP) sequencing primers to the Molecular Ecology Resources Database. Loci were developed for the following species: Alcippe morrisonia morrisonia, Bashania fangiana, Bashania fargesii, Chaetodon vagabundus, Colletes floralis, Coluber constrictor flaviventris, Coptotermes gestr...
The embryonic and larval development of the pipefish Syngnathus abaster is described, based on ex situ observations. The full development sequence lasted 24–32 days (at 18–19 C), which was shortened to 21 days at higher temperatures (21–22 C). Newborn juveniles, with a uniform dark brown colouration, immediately assumed a benthic spatial distribution. This vertical distribution pattern remained...
The aim of this study was to evaluate the benthic diatom composition from the estuary sediment in the Pernambuco State, based on 32 samples. Samples were collected monthly from September through December 1999 (dry period) and from April through July 2000 (rainy period) during four pre established sampling stations. Results indicated 19 families and 31 specific and infraspecific taxa. Eight new ...
