The Length-Weight Relationship and Condition Factor of the Red Cornetfish, Fistularia petimba Lacepède, 1803 in the Southeastern Mediterranean Coast of Türkiye (İskenderun Bay)

Turkish Journal of Bioscience and Collections, 2023
Objective: In fisheries biology, length-weight relationship data are commonly used and helpful for determining the weight of an individual fish of known total length or total weight from length-frequency distribution.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Voices From the Coast: Stakeholder Participation and Perception on Creating a Marine Protected Area

Business Strategy and the Environment, EarlyView.
ABSTRACT This study explores participatory processes in the context of marine conservation, with a specific focus on recent initiatives undertaken by the Apulia region in Italy to establish a new Marine Protected Area (MPA). Employing a qualitative cross‐sectional methodology, the study investigates how local communities perceive and engage with the ...

Estimating dietary protein, energy, and amino acid requirements of European catfish (Silurus glanis Linnaeus, 1758) across different growth stages using a bioenergetic approach

Aquaculture and Fisheries
There is a lack of information about the nutritional requirements of European catfish (Silurus glanis) for aquaculture. This study aimed to fill this gap using a bioenergetic factorial model. To develop the model, a series of sub-studies were carried out.

Viability and Management Targets of Mediterranean Demersal Fisheries: The Case of the Aegean Sea.

PLoS ONE, 2016
Management of the Mediterranean demersal stocks has proven challenging mainly due to the multi-species character of the fisheries. In the present work, we focus on the multi-species demersal fisheries of the Aegean Sea (eastern Mediterranean) aiming to ...

Stochastic and deterministic processes influencing mountain mire diatom communities across spatial scales

Ecography, EarlyView.
Understanding how deterministic and stochastic processes influence the shape of microorganism community assembly across different spatial scales is essential for disentangling biodiversity patterns. Mires are nutrient‐poor and heterogeneous wetlands that form isolated habitats supporting highly diverse diatom assemblages, particularly in mountainous ...

Ecosystem Models and Effort Simulations of an Untrawled Gulf in the Central Aegean Sea

Frontiers in Marine Science, 2019
Ecosystem models can be used as fisheries management tools in the context of a holistic approach and view of assessing the status of aquatic ecosystems and proposing plans of action. The Ecopath with Ecosim modeling suite has been widely used to describe

Fisheries Mismanagement in the Mediterranean: A Greek Tragedy [PDF]

Fisheries and Aquaculture Journal, 2014
One of the main objectives of fisheries management is the reduction of fishing capacity and effort at a global scale [1], since the global fishing fleet is at least twice higher than should have been to allow for fish stock replenishment [2], and locally, in cases where overexploitation is evident [3].

Latitudinal effect on the structure of snake–prey interaction networks is mediated by snake species richness

Ecography, EarlyView.
Despite the growing number of studies on trophic networks in recent decades, there are still important gaps in our understanding of how these networks are structured across broad environmental gradients. These gaps are even greater in some groups of terrestrial vertebrates, such as snakes, requiring a cohesive synthesis of their broader trophic ...
