Identification and characterization of nursery areas of red mullet Mullus barbatus in the Central Tyrrhenian Sea [PDF]

open access: yes, 2017
Red Mullet Mullus barbatus is an important target of fishing activities in the central Tyrrhenian Sea, so it is essential to identify its critical habitats in order to manage this resource efficiently.

The German Bight (North Sea) is a nursery area for both locally and externally produced sprat juveniles [PDF]

open access: yes, 2009
To better understand the role of the German Bight (GB) as a nursery area for juvenile North Sea sprat Sprattus sprattus we sought to determine whether the area may receive only locally or also externally produced offspring.

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;

First insights into coral recruit and juvenile abundances at remote Aldabra Atoll, Seychelles

open access: yesPLOS ONE, 2021
Coral recruitment and successive growth are essential for post-disturbance reef recovery. As coral recruit and juvenile abundances vary across locations and under different environmental regimes, their assessment at remote, undisturbed reefs improves our understanding of early life stage dynamics of corals.

A two-species stage-structured model for West Nile virus transmission [PDF]

open access: yes, 2017
We develop a host–vector model of West Nile virus (WNV) transmission that incorporates multiple avian host species as well as host stage-structure (juvenile and adult stages), allowing for both species-specific and stage-specific biting rates of vectors ...

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.

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

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.

Morphological abnormalities in some dominant fish species from the polluted site of the Pozim River (Udmurt Republic, Russia)

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2021
Morphological abnormalities resulting from the anthropogenic load on juveniles of five cyprinid species (common roach (Rutilus rutilus Linnaeus, 1758), common rudd (Scardinius erythrophthalmus Linnaeus, 1758), ide (Leuciscus idus Linnaeus, 1758 ...

AMPHIBIAN AND REPTILE COLONIZATION OF RECLAIMED COAL SPOIL GRASSLANDS [PDF]

open access: yes, 2014
While habitat loss is a major driver of amphibian and reptile declines globally, a subset of post-industrial landscapes, reclaimed and restored, are creating habitat for these animals.

Egg size and food abundance interactively affect juvenile growth and behaviour [PDF]

open access: yesFunctional Ecology, 2010
Summary1. Comparative evidence from several animal taxa suggests that juveniles hatching from larger eggs have fitness benefits when growing up in a harsh environment, whereas under benign conditions egg size should be of less importance. However, the physiological and behavioural mechanisms responsible for these context‐dependent fitness differences ...
