Determination of zooplankton characteristics in the presence of surface feeding basking sharks Cetorhinus maximus
Zooplankton samples were taken in the presence (n 68) and absence (n = 65) of surface f e e d ~ n g zooplanktlvorous basking sharks Cetorh~nus mavimus off Plymouth, southwest England, from May to mid-August, 1995-96 A prelim~nary study In 1995 showed zooplankton density (g m-3) to be 46% higher in samples taken near feeding sharks Calanoid copepods predominated In all samples but were 84 O,rl m...
متن کاملLow worldwide genetic diversity in the basking shark (Cetorhinus maximus).
The basking shark (Cetorhinus maximus) is found in temperate waters throughout the world's oceans, and has been subjected to extensive exploitation in some regions. However, little is known about its current abundance and genetic status. Here, we investigate the diversity of the mitochondrial DNA control region among samples from the western North Atlantic, eastern North Atlantic, Mediterranean...
متن کاملHabitat suitability modelling and niche theory
1. The concept of the ecological niche relates a set of environmental variables to the fitness of species, while habitat suitability models (HSMs) relate environmental variables to the likelihood of occurrence of the species. In spite of this relationship, the concepts are weakly linked in the literature, and there is a strong need for better integration. 2. We selectively reviewed the literatu...
متن کاملSeasonal Variation in the Spatial Distribution of Basking Sharks (Cetorhinus maximus) in the Lower Bay of Fundy, Canada
The local distribution of basking sharks in the Bay of Fundy (BoF) is unknown despite frequent occurrences in the area from May to November. Defining this species' spatial habitat use is critical for accurately assessing its Special Concern conservation status in Atlantic Canada. We developed maximum entropy distribution models for the lower BoF and the northeast Gulf of Maine (GoM) to describe...
متن کاملmodelling of persian gazelle (gazella subgutturosa subgutturosa) habitat suitability using ecological niche factor analysis method in gharaviz no hunting area
gharaviz no hunting area is known as one of the most important habitats of persian gazelle (gazella subgutturosa subgutturosa) in west zagros mountains. developing models to predict the distribution of wildlife is suitable tool for conservation and management. in this approach, the boundary of the study area was considered the distribution area and then were compared with actual region. field d...
