  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by:  Tayfun Kurt Abstract This study introduces a new integrated approach to drought susceptibility mapping in the Medina Region of Saudi Arabia by combining geomorphometric and hydrological indicators derived from high-resolution ALOS PALSAR DEM data. Using QGIS 3.42, key topographic parameters such as slope, aspect, Topographic Wetness Index (TWI), Stream Power Index (SPI), and the Drought Geomorphological Unit-based Index (Drought Index) were extracted and harmonized within a GIS-based Multi-Criteria Decision Analysis (MCDA) framework. The integrated analysis enabled the identification of spatial patterns of drought risk and delineation of high-susceptibility zones. The results offer actionable insights for targeted drought mitigation, sustainable water resource planning, and environmental management in hyper-arid regions where conventional climatic data are limited. This approach demonstrates th...

Benefits of publishing with Juniper Publishers

Publishing with Juniper publishers offers several important benefits for authors, researchers, and the broader community. Here are some key advantages: 1. Increased Visibility and Reach Open Access articles are freely available online, making them accessible to anyone with an internet connection. This typically results in higher readership and greater exposure, especially in developing countries or institutions without subscription access. 2. Higher Citation Rates Studies have shown that Juniper articles often receive more citations than paywalled articles, due to their wider availability. 3. Faster and Broader Impact Juniper publishers speed up the dissemination of research findings, leading to quicker uptake by practitioners, policymakers, and fellow researchers. This can be particularly important in fields like medicine, public health, and environmental science. 4. Compliance with Funders' Requirements Many funding bodies and institutions strongly encourage Juniper Publishers to...

Controlling Factors of the Population Dynamics of Two Dominant Bivalves of the Macro-benthic Community on the Sandy Tidal Flats

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by:  Hiroaki Tsutsumi Abstract The edible short-neck clam, Ruditapes philipinnarum , is one of the most dominant species in the macro-benthic community on the sandy tidal flats that face Ariake Bay in Kumamoto Prefecture, western Japan. Until the 1970s, over 40,000 tons of the clams were collected per year on the tidal flats. However, the dense patches disappeared, and the clam-harvesting fishery has suffered from extremely poor catches of less than 500 tons per year over the past three decades. We conducted environmental assessments of the sediment and did quantitative surveys of the macro-benthic community on Midori River Tidal Flats located in Kumamoto between April 2017 and April 2019 and tried to find the reasons why the clam population markedly declined. Asian mussels ( Arcuatula senhousia ) and short-neck clams predominated the macro-benthic community on the tidal flats. Howeve...

What Indicators Could be Useful to Understand the Development of Digestive Tract, During the Early Ontogeny of Teleost Fish?

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Cuenca-Soria C A Abstract Nowadays, the most of studies about the digestive physiology and structure changes during the initial ontogeny of cultured fish, have been focused to describe the indicators (associated with those changes), punctual and reclusively. Moreover, there are not enough indicators, when the digestive morphological and functional changes, are described in certain fish in particular. The present review, try to describe and compile the indicators of digestive morpho functional development, attending the feed habits, as well as the kind of ontogeny that undergo the teleost fish, which, it almost not be considered. The review tries to explain, the importance of show possible synergy between biochemistry (enzymology), histological, histochemical, molecular, mainly genomic aspects (among others); towards an integral and reliable description of the morpho functional changes...
