Does habitat complexity influence fish recruitment?

Habitat complexity modifies post-settlement mortality and recruitment dynamics of a marine fish.

For species that have an open population structure, local population size may be strongly influenced by a combination of propagule supply and post-settlement survival. While it is widely recognized that supply of larvae (or recruits) is variable and that variable recruitment may affect the relative contribution of pre- and post-settlement factors, less effort has been made to quantify how varia...

Lake Habitat: Acres of “Prime” Fish Habitat

Does habitat or depth influence catch rates of pelagic species?

The efficiency of a pelagic longline fishing operation and the species composition of the resulting catch is influenced primarily by the relationship between the distribution of hooks and species vulnerability, with vulnerability described by either depth or some suite of environmental variables. We therefore fitted longline catch rate models to determine whether catch is estimated better by ve...

Does cigarette smoking influence acne?

Introduction: Acne is a common problem in adolescent and youngage groups, for which several risk factors have been suggested.One of the risk factors is smoking. In studies on the relationshipbetween smoking and acne, conflicting results have been obtained.Method: This study was conducted on 133 male patients whowere visited at the dermatology clinic of Imam Reza hospital dueto acne as the case ...

Predictability of reef fish recruitment in a highly variable nursery habitat.

There has been a lengthy debate on whether the abundance of adult reef fishes depends on prerecruitment or postrecruitment processes; however, we still do not have the ability to predict the magnitude of local fish recruitment. Here we show that the success of the leopard grouper (Mycteroperca rosacea) recruitment in the Gulf of California, Mexico, is determined by the availability of nursery h...
