Statement to Water Resources Subcommittee of House Committee on Public Works and Transportation for a Hearing, May 24 and 25, 1978, Washington, D.C. regarding Secondary Treatment Waivers and Ocean Outfalls [PDF]

open access: yes, 1978
The principal technical reason for having a waiver provision for secondary treatment for municipal discharges is that for some outfall systems the dilution is so high that very good ambient water quality can be achieved with less than secondary ...

Characterizing morphology of Egregia menziesii (Laminariales) in California over 2 centuries using historical and contemporary herbarium specimens

open access: yesJournal of Phycology, EarlyView.
Abstract The canopy‐forming feather boa kelp Egregia menziesii exhibits remarkable morphological variability across its geographic range. Regional morphotypes of Egregia were once considered separate species, but they were not determined to be genetically distinct; instead, their morphology was thought to reflect local physical or environmental ...

Genetic Basis of UV Bullseye Size Variations in Turnip Rape (Brassica rapa subsp. oleifera)

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Floral ultraviolet (UV) patterns are visible to bee pollinators and can affect crop yields by impacting pollinator visitation. However, the mechanisms underlying the intraspecific variations of UV bullseye size remain largely unknown. We analyse the ecological consequences and genetic basis of floral UV bullseye size variation in an important ...

A review of the ecological effectiveness of subtidal marine reserves in Central California, Part I: Synopsis of scientific investigations [PDF]

open access: yes, 2004
Marine reserves, often referred to as no-take MPAs, are defined as areas within which human activities that can result in the removal or alteration of biotic and abiotic components of an ecosystem are prohibited or greatly restricted (NRC 2001 ...

Effects of temperature on sexual competition in three kelp species, Pterygophora californica, Nereocystis luetkeana, and Macrocystis pyrifera: Implications for range shifts in foundation species

open access: yesPhycological Research, EarlyView.
SUMMARY Kelp forests are threatened by rising ocean temperatures. However, the effects of warming on early life stage interactions among co‐occurring kelp species, particularly competitive dynamics and reproductive timing, remain poorly understood. This study investigates the effects of temperature on embryonic sporophyte competitive interactions and ...

Benthic fauna dynamics following large‐scale seagrass restoration in an exposed environment

open access: yesRestoration Ecology, EarlyView.
Seagrass meadows are vital habitats, modifying hydrodynamic energy flows and sustaining biodiversity in the benthic environment. As such, there is a growing interest in using seagrass as a nature‐based solution for coastal adaptation. However, planting seagrass in hydrodynamically exposed environments is challenging, and the trajectories and timescales

Ground-water resources of the lower Hillsboro Canal area, Southeastern Florida [PDF]

open access: yes, 1970
This study was done to determine the amount and kinds of water being produced from the lower Hillsboro Canal Area in Palm Beach and Broward counties. All of the potable ground water being produced from the Biscayne aquifer is developed from the canal
