Gender and marine protected areas: a case study of Danajon Bank, Philippines.

Abstract In this paper, we examine the role of gender in community-based management of marine protected areas (MPAs) in the Central Philippines. MPAs are a common conservation and fisheries management tool in this area, but the relationship between gendered fishing practices and participatory MPA management is rarely considered. In this region, women and men’s fishing … Read more Gender and marine protected areas: a case study of Danajon Bank, Philippines.

Changes in the trade of bycatch species corresponding to CITES regulations: the case of dried seahorse trade in Thailand.

Abstract Exploitation for trade is one of the biggest threats to many species, especially for marine fishes. Trade regulations should, therefore, be effective in helping conserve marine fish populations. The Convention of International Trade in Endangered Species of Wild Fauna and Flora (CITES), one of the few multilateral environmental agreements with enforcement capacity, has embraced … Read more Changes in the trade of bycatch species corresponding to CITES regulations: the case of dried seahorse trade in Thailand.

Identifying key environmental variables of two seahorse species (H. guttulatus and H. hippocampus) in the Ria Formosa lagoon, South Portugal

Recent findings reported a significant decrease in abundance of two seahorse species (Hippocampus guttulatus and H. hippocampus) in the Ria Formosa lagoon (South Portugal) and no direct causes have been, so far, clearly identified. This study aimed to describe fluctuations in the local seahorse populations through monthly surveys over a course of a year, in … Read more Identifying key environmental variables of two seahorse species (H. guttulatus and H. hippocampus) in the Ria Formosa lagoon, South Portugal

Costs and benefits of changing sampling methods in long-term monitoring of marine protected areas

To confirm their effectiveness, long-term monitoring of marine protected areas (MPAs) is critical. Such longitudinal sampling can, however, pose problems of methodology, particularly as more preferred tools may evolve over time. My research sought to understand how two commonly used methods, line intercept transect (LIT) and photoquadrat (PQ), which were used sequentially in MPA monitoring, … Read more Costs and benefits of changing sampling methods in long-term monitoring of marine protected areas

Predicting distributions, habitat preferences and associated conservation implications for a genus of rare fishes, seahorses (Hippocampus sp)

Aim: To identify useful sources of species data and appropriate habitat variables for species distribution modelling on rare species, with seahorses as an example, deriving ecological knowledge and spatially explicit maps to advance global seahorse conservation. Location: The shallow seas. Methods: We applied a typical species distribution model (SDM), maximum entropy, to examine the utility … Read more Predicting distributions, habitat preferences and associated conservation implications for a genus of rare fishes, seahorses (Hippocampus sp)

Shifting gears: Diversification, intensification, and effort increases in small-scale fisheries (1950-2010)

Locally sustainable resource extraction activities, at times, transform into ecologically detrimental enterprises. Understanding such transitions is a primary challenge for conservation and management of many ecosystems. In marine systems, over-exploitation of small-scale fisheries creates problems such as reduced biodiversity and lower catches. However, long-term documentation of how governance and associated changes in fishing gears may … Read more Shifting gears: Diversification, intensification, and effort increases in small-scale fisheries (1950-2010)

Reporting time period matters: quantifying catch rates and exploring recall bias from fisher interviews in Thailand

Catch rates reported by fishers are commonly used to understand the status of a fishery, but the reliability of fisher reported data is affected by how they recall such information. Recalling catch may be influenced by the choice of reporting time period. Using interview data from fishers in Thailand, we investigated (1) how the time … Read more Reporting time period matters: quantifying catch rates and exploring recall bias from fisher interviews in Thailand

A synthesis of European seahorse taxonomy, population structure, and habitat use as a basis for assessment, monitoring and conservation

Accurate taxonomy, population demography, and habitat descriptors inform species threat assessments and the design of effective conservation measures. Here we combine published studies with new genetic, morphological and habitat data that were collected from seahorse populations located along the European and North African coastlines to help inform management decisions for European seahorses. This study confirms … Read more A synthesis of European seahorse taxonomy, population structure, and habitat use as a basis for assessment, monitoring and conservation

Seahorse exploitation and trade in Viet Nam

The Convention on International Trade in Endangered Species of wild Fauna and Flora (CITES) decided to implement export controls for all seahorses in 2002, the first such controls for any marine fishes. Viet Nam had difficulties implementing CITES regulations and was eventually subject to an export trade suspension in 2013. To help address gaps in … Read more Seahorse exploitation and trade in Viet Nam
