And Migration

An age-dependent generalization of the Jolly–Seber mark–recapture model for fish populations subject to birth, death, and migration is illustrated using data from a study on northern pike (Esox lucius) in Dorset, England. These data show strong evidence of differential survival with age. We estimate the average annual survival rate to be 50% for the pike aged 2 or more years and 34% for those of age 1 yr. We believe that this age-dependent mark–recapture model could be very useful for a wide range of fisheries research and management problems. Often in fisheries work the assumption that survival is independent of age has not been examined critically. We present guidelines helpful in designing mark–recapture studies. This includes a useful design which increases precision and also allows population size estimation to be robust to unequal catchability (heterogeneity or trap response) within an age-class.

ABSTRACT Estimating population parameters is essential for understanding the ecology of species, which ultimately helps to assess their conservation status. The seahorse Hippocampus reidi is directly exposed to anthropogenic threats along the Brazilian coast, but the species still figures as Data Deficient (DD) at IUCN’s Red List. To provide better information on the ecology of this species, we studied how population parameters vary over time in a natural subtropical environment. By combing mark-recapture models for open and closed populations, we estimated abundance, survival rate, emigration probability, and capture probability. We marked 111 individuals, which showed a 1:1 sex ratio, and an average size of 10.5 cm. The population showed high survival rate, low temporary emigration probability and variable capture probability and abundance. Our models considering relevant biological criteria illuminate the relatively poorly known population ecology and life history of seahorses. It is our hope that this study inspires the use of mark-recapture methods in other populations of H. reidi in a collective effort to properly assess their conservation status.

Lobster pasir (Panulirus homarus) merupakan salah satu jenis lobster yang memiliki nilai ekonomis penting dan banyak ditangkap di Indonesia. Salah satu cara untuk mengetahui pertumbuhan, tingkat kelangsungan hidup dan pergerakan lobster di alam adalah dengan menggunakan metode Capture-mark-recapture (CMR). Tiga jenis tag yang biasa dipakai untuk penandaan lobster adalah T-bar, streamer, dan Visual Implant Elastomer (VIE). Percobaan penandaan dilakukan di kolam penampungan di Teluk Gerupuk, Lombok Tengah. Penelitian  ini bertujuan untuk mendapatkan jenis tag yang efektif untuk mengetahui tingkat kelangsungan hidup pada lobster pasir. Penelitian dilakukan dengan menggunakan tiga jenis tag, yaitu T-bar (70 ekor), streamer (76 ekor), dan Visual Implant Elastomer (VIE) (10 ekor) pada dua kelompok ukuran lobster (>20-60 gram dan >60-100 gram). Semua sampel dipelihara dalam bak selama 30 hari yang dilakukan Agustus-September 2015. Hasil penelitian menunjukkan bahwa VIE (60%) memiliki tingkat kelangsungan hidup tertinggi diikuti oleh T-bar (34 %) dan steamer (13 %). Untuk keperluan monitoring di alam, disarankan menggunakan T-bar karena penerapannya praktis dan mudah dideteksi. Panulirus homarus (Spiny Lobster) is one of the lobster species that has an important economic value and highly catched in Indonesia. Capture-mark-recapture (CMR) methods are widely used to study the estimation of population parameters such as abundance, growth, distribution and survival of the wild organism. Three effective techniques commonly used for decapods tagging are  T-bar, streamer, and Visual Implant Elastomer (VIE). Tagging experiments conducted in ponds in the Gulf Gerupuk, Central Lombok. This study aims to determine the effective type of tags and to determine the survival rate of spiny lobster. The study was conducted using three types of tags, T-bar (70 lobsters), streamer (76 lobsters), and Visual Implant Elastomer (VIE) (10 lobsters) divided in two groups size of lobster (> 20-60 grams and> 60- 100 grams). All samples were maintained in the tank for 30 days in August-September, 2015. The results showed that VIE (60%) has the highest survival rate followed by the T-bar (34%) and streamer (13%). For monitoring purposes in nature T-bar are advised to use because of their more practical applicated and easily detected.

Abstract. This article analyses if and to what extent gender differences exist in abdominal aortic aneurysm (AAA) therapy. For this purpose Medline (PubMed) was searched from January 1999 to January 2018. Keywords were: “abdominal aortic aneurysm”, “gender”, “prevalence”, “EVAR”, and “open surgery of abdominal aortic aneurysm”. Regardless of open or endovascular treatment of abdominal aortic aneurysms, women have a higher rate of complications and longer hospitalizations compared to men. The majority of studies showed that women have a lower survival rate for surgical and endovascular treatment of abdominal aneurysms after both elective and emergency interventions. Women receive less surgical/interventional and protective medical treatment. Women seem to have a higher risk of rupture, a lower survival rate in AAA, and a higher rate of complications, regardless of endovascular or open treatment. The gender differences may be due to a higher age of women at diagnosis and therapy associated with higher comorbidity, but also because of genetic, hormonal, anatomical, biological, and socio-cultural differences. Strategies for treatment in female patients must be further defined to optimize outcome.
