The North Shore Mosquito Abatement District applies extended release larvicides including methoprene-based Altosid® XR Extended Residual Briquets to approximately 40,000 catch basins in the southern half of the District's operational area at the beginning of each season. Treatments begin in May and typically again 9 to 10 wk later when larvicide efficacy appears to wane. In 2013 spinosad-based ...

Ecohydrology 2016; 1–13 Abstract Despite controversy about effects of plantation forestry on streamflow, streamflow response to forest plantations over multiple decades is not well understood. Analysis of 60‐year records of daily streamflow from eight paired‐basin experiments in the Pacific Northwest of the United States (Oregon) revealed that the conversion of old‐growth forest to Douglas‐fir ...

The amount of water held in individual wetland basins depends not only on local climate patterns but also on groundwater flow regime, soil permeability, and basin size. Most wetland basins in the northern prairies hold water in some years and are dry in others. To assess the potential effect of climate change on the number of wetland basins holding water in a given year, one must first determin...

In order to draw patterns in helminth parasite composition and species richness in Mexican freshwater fishes we analyse a presence-absence matrix representing every species of adult helminth parasites of freshwater fishes from 23 Mexican hydrological basins. We examine the distributional patterns of the helminth parasites with regard to the main hydrological basins of the country, and in doing ...

The relative importance of contemporary and historical processes is central for understanding biodiversity patterns. While several studies show that past conditions can partly explain the current biodiversity patterns, the role of history remains elusive. We reconstructed palaeo-drainage basins under lower sea level conditions (Last Glacial Maximum) to test whether the historical connectivity b...

Regional differences in clay mineralogy are found in British Lower Palaeozoic slate belts formed during Caledonian terrane amalgamation. Extensional basins in Wales, the northern Lake District and the Isle of Man are characterized by a greater diversity of species in clay mineral assemblages. Slates that evolved in these basins contain both the Kand Na-rich products of the 2:1 dioctahedral reac...

We investigate the well known Newton method to find roots of entire holomorphic functions. Our main result is that the immediate basin of attraction for every root is simply connected and unbounded. We also introduce “virtual immediate basins” in which the dynamics converges to infinity; we prove that these are simply connected as well.

The purpose of this work is to study the dynamics of a discrete bidimensional dynamical system which depends on a real parameter. This system is obtained by a perturbation of a holomorphic polynomial whose Julia set is well known. The attractors of the initial system, as well as their attractive basins, are determined. Different types of bifurcations are identified.

The study of peak-ring basins and other impact crater morphologies transitional between complex craters and multi-ring basins is important to our understanding of the mechanisms for basin formation on the terrestrial planets. Mercury has the largest population, and the largest population per area, of peak-ring basins and protobasins in the inner solar system and thus provides important data for...

Valley networks are mapped from mosaics composed of 100 m/pixel THEMIS images for 8 sites in Martian highlands. The sites are subdivided into individual drainage basins using 500 m/pixel DEMs co-registered with image mosaics. Terrain parameters are calculated for each basin with area > 10 km. Drainage densities of individual basins are 0 0.29 km−1. There is a moderate (r=0.5) correlation betwee...
