2. 1. Habitat structure, degradation and management effects on coral reef fish communities

   Author : Saleh A.S. Yahya; Martin Gullström; Sören Nylin; Narriman Jiddawi; Yunus Mgaya; Gunilla Rosenqvist; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fish assemblages; climate change; coral degradation; Indian Ocean; patch reefs; coral bleaching; resilience; zoologisk ekologi; Animal Ecology;

   Abstract : Coral reefs are among the most diverse and productive ecosystems on earth, and are critical to the survival of tropical marine ecosystems and sustenance of local human populations. However, coral reefs are quite vulnerable to disturbances, both natural and anthropogenic. READ MORE

4. 2. Evolution of eyes: Pax, gene duplications & morphology

   Author : Karin Nordström; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal morphology; Djurs anatomi och morfologi; Animal anatomy; tetraploidization; planula; phototransduction; pax; paired domain; mutagenesis; cnidaria; eye evolution;

   Abstract : During the course of evolution animal complexity and diversity is generated. The last couple of years it has become increasingly clear that morphologically diverse animals share a great deal of their genomic contents, and it must be the expression of regulatory genes in new setting, rather than the generation of new genes, that are fundamental for the generation of diversity.

5. 3. Fish community patterns in Tanzanian mangrove creeks

   Author : Augustine Mwandya; Martin Gullström; Olof Lindén; Stockholms universitet; []
   Keywords : Mangrove ecosystems; fish assemblages; Mugil cephalus; population genetics; spatial and seasonal variability; human disturbance; East Africa; NATURAL SCIENCES; NATURVETENSKAP; Animal Ecology; zooekologi;

   Abstract : Human beings have exploited the biota of mangrove systems for centuries and fish continue to be one of the main products harvested from these habitats. The assumption of mangroves functioning as recruitment areas for juvenile fish from neighbouring habitats such as seagrass beds and coral reefs is a common argument for conservation and management of mangrove ecosystems.

6. 4. Migration of Sea Turtles from Caribbean Costa Rica: Implications for Management

   Author : Sebastian Troëng; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; conservation; predation; remigration; annual survival probability; mtDNA; satellite telemetry; tagging; Costa Rica; Tortuguero; endangered; migration; Djurekologi; sea turtles;

   Abstract : Tortuguero National Park in Costa Rica hosts nesting by four species of highly migratory and endangered sea turtles (green, hawksbill, leatherback and loggerhead turtles). Sea turtle research at Tortuguero has been continuous since Dr. Archie Carr began studies in the 1950?s. READ MORE

7. 5. Ecotoxicological studies on giant clams (Tridacnidae) : Environmental problems and future concerns

   Author : Eva Blidberg; Michael Tedengren; David Klumpp; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; giant clam; larval; physiology; zooxanthellae; Biology; Biologi;

   Abstract : Giant clams (Tridacnidae; Bivalvia) are described as important framework builders on coral reefs in the Indo-Pacific region. They are phototrophic as they are associated with primary producing zooxanthellae. Populations are low due to over-exploitation and most species are now endangered in many areas. READ MORE
