Larval transport
"Larval transport .. is.. the mean
horizontal translocation of larvae between points along a
specified one-dimensional axis per unit time (with units L
/ time)". "This definition does not consider timing and
magnitude of spawning, larval abundance, mortality,
or
settlement (discussed in Pineda et al., 2007). It
acknowledges the separation of pelagic and benthic
habitats, and accommodates the mechanistic resolution of
the fundamental biological-physical processes accounting
for larval translocation along a spatial dimension of
interest (e.g., alongshore, cross-shore)" .(See
Pineda and
Reyns, 2018, and also
Pineda, Hare and Sponaugle, 2007)
Larval dispersal
"Larval dispersal refers to the spread
of larvae from a spawning source to a settlement site.
This definition is consistent with the terrestrial
literature (natal dispersal in Clobert et al., 2001; Begon
et al., 2006) that describes seed dispersal as the
probability density function of the number of seeds versus
distance from the adult source (i.e., the dispersal
kernel) (Nathan and Muller-Landau, 2000; see Gerrodette,
1981, for a rare marine example)."
(See Scheltema, 1986 and
Pineda, Hare and Sponaugle, 2007)
Population connectivity
"Population connectivity has been
defined as the exchange of individuals among
geographically separated subpopulations...By this
definition, if the exchange is measured at the time of
settlement, connectivity is essentially larval dispersal
from one population to another"
(See Cowen et al., 2007, Oceanography,
and Pineda, Hare and Sponaugle, 2007)
Reproductive population
connectivity
The dispersal of individuals among
subpopulations that survive to reproduce (see
Pineda, Hare and Sponaugle, 2007)
Nearshore
"The nearshore zone includes (a) the
shallow waters where surface and bottom Ekman layers
interact, the nearshore of Mitchum and Clarke (1986), and
the inner shelf of Lentz (1995), and (b), the surfzone.

ARE BARNACLES BORING?
Trevor Noah on the Daily Show -Comedy Central
A poem by Pablo Neruda:
| PICOROCO |
| El picoroco encarcelado |
| está en una torre terrible, |
| saca una garra azul, |
| palpita desesperado en el tormento. |
| |
| Es tierno adentro de su torre: |
| blanco como harina de mar |
pero nadie alcanza el secreto
de su frío castillo gótico.
|
THE PICOROCO
The picoroco imprisoned
in a terrible tower,
extends a blue claw, palpitates,
desperate
in the storm.
The picoroco is tender
inside its tower:
white as flour of the sea
but no one can reach the secret
of its
cold gothic castle.
(English translation
by M. Jacketti, D. Maloney and C. Zlotchew) |
