In west coast groundfish stock assessments, biological productivity is largely defined by a single parameter, i.e., steepness (h) of the Beverton-Holt spawner-recruit curve, which ranges from 0.20 (no compensation) to 1.00 (complete compensation). A steepness of 0.20 implies no latent surplus production and a total lack of resilience to the effects of exploitation, whereas a value of 1.0 implie...

a r t i c l e i n f o Slow-moving landslides exhibit persistent downslope motion with variations in velocity driven by transient stress perturbations along the sliding surface. Here, we use satellite InSAR and high-resolution topographic data to identify 50 slow-moving landslides in the Northern California Coast Ranges, and monitor their seasonal kinematics over 4 years. These landslides have s...

Long-distance migration is a behavior that is exhibited by many animal groups. The evolution of novel migration routes can play an important role in range expansions, ecological interactions, and speciation. New migration routes may evolve in response to selection in favor of reducing distance between breeding and wintering areas, or avoiding navigational barriers. Many migratory changes are li...

The majority of weather station records indicate that surface air temperatures have been warming in California between 1950 and 2005. Temperature data from the mid-1990s to the present were analyzed for stations on California Central Coast near Big Sur (Monterey County) to better understand potential for climate change in this biologically unique region. Results showed that daily temperatures i...

The beautiful coast of Kerala is as much a part of the unique dynamics of Kerala's social history as its natural history. The several ports on the coast facilitated commercial and cultural links of a population confined between the idyllic Western Ghats ranges and the Arabian Sea. These links extended to almost all the major ancient civilizations in the world. The fortuitous winds blowing over ...

We investigated the current geographic distribution of species of Ameivula and Contomastix along the Brazilian coast. We also estimated population sizes and conservation status of species from both genera and recorded potential sources of habitat degradation. Fieldwork was carried out in 12 areas of restinga (coastal sandy plain) from northeastern (Rio Grande do Norte) to southern Brazil (Santa...

Species distribution models were constructed for ten Ixodes species and Amblyomma cajennense for a region including Mexico and Texas. The model was based on a maximum entropy algorithm that used environmental layers to predict the relative probability of presence for each taxon. For Mexico, species geographic ranges were predicted by restricting the models to cells which have a higher probabili...

The fouling barnacle Amphibalanus improvisus is a cosmopolitan biomonitor of trace metal bioavailability in coastal waters of reduced salinity such as estuaries or the Baltic Sea. Bioavailability of Ag, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn to A. improvisus was investigated in July 2014 at 15 sites along the Iranian coast of the understudied, yet biologically unique, Caspian Sea. In gene...
