Juvenile Coral Abundance Has Decreased by More Than 50% in Only Three Decades on a Small Caribbean Island [PDF]

open access: yesDiversity, 2011
A comparison of the community structure of juvenile hermatypic corals of 2 to 37 m depth at the fringing reefs of Curaçao between 1975 and 2005 shows a decline of 54.7% in juvenile coral abundance and a shift in species composition.

The relationship between physical and biological habitat conditions and hermatypic coral recruits abundance within insular reefs (Colombian Caribbean)

open access: yesRevista de Biología Tropical, 2012
Little evidence exists on the dependence between the presence and abundance of juvenile hermatypic corals and the conditions of their habitats, despite that juveniles contribute with the understanding of the community structure and its reproductive ...

Vertical distribution and abundance of juvenile cephalopods in Aegean Sea

open access: yesScientia Marina, 2003
This study was carried out in northern (Saros Bay) and southern (Gökova Bay) parts of the Aegean Sea. In pelagic samplings, Hamburg Plankton Net (HPN) was used. Samplings were done out at four different periods of a 24 hour day; sunrise, noon, sunset and midnight. Horizontal hauls were carried out at depths of 100, 350 and 650 m.

Host Abundance, Juvenile Survival, and Oviposition Preference in Battus philenor [PDF]

open access: yesEvolution, 1980
Many phytophagous insects are highly specific with respect to the plants on which they lay eggs, restricting oviposition to plant species within one family or group of related families (Brower and Brower, 1964; Ehrlich and Raven, 1964; Eastop, 1973), or even to species or groups of species within a particular family or genus (Singer, 1971; Janzen, 1974;

Linking stress coping styles with brain mRNA abundance of selected transcripts for Senegalese sole (Solea senegalensis) juveniles [PDF]

open access: yes, 2019
In fish, proactive and reactive individual stress copying styles (SCS) have been used to resolve variation in molecular expression data. Stress coping styles have been previously described in several stages of Solea senegalensis by validating for the ...

Belowground Distribution and Abundance of Botrychium Gametophytes and Juvenile Sporophytes

open access: yesAmerican Fern Journal, 2002
Abstract A significant portion of the stages of the life history of Botrychium, the gametophyte and juvenile sporophytes, are spent belowground. Surveys were conducted to determine the distribution and abundance of belowground gametophytes, juvenile sporophytes and gemmae of eight species of Botrychium.
