In infrapopulations of helminth parasites, density-dependent effects, through some form of intra- and interspecific competition, play an important role in shaping and regulating the infrapopulations. The mechanisms responsible for these processes have often been observed in laboratory studies and rarely studied under natural conditions. Here, 24 natural infrapopulations (77-447 individuals) of ...

Prey traits linking consumer diversity to ecosystem function remain poorly understood. On tropical coral reefs, herbivores promote coral dominance by suppressing competing macroalgae, but the roles of herbivore identity and diversity, macroalgal defenses, and their interactions in affecting reef resilience and function are unclear. We studied adjacent pairs of no-take marine reserves and fished...

The fisheries of Hawaii and other u.S.-associated islands in the Pacific Ocean are characterized by high diversity, both in the species exploited and the human cultures that exploit them. The commercial sector has undergone rapid growth in recent years, but recreational and subsistence sectors remain important. Information on these fisheries is generally not available in published form. This pa...

Streptococcus iniae is one of the few Gram positive streptococcal species capable of hydrolyzing starch. The starch hydrolysis test is essential for its identification. The biochemical reaction for starch in multi-test systems (API 20 Strep and API CH 50) is starch acidification, not starch hydrolysis. Furthermore, API systems do not contain S. iniae in their databases, yet fish disease researc...
