Bull trout (Salvelinus confluentus) exhibit binge‐feeding and digestive flexibility during seasonal resource pulses associated with salmon migrations

open access: yesJournal of Fish Biology, EarlyView.
Abstract Resource pulses are infrequent, ephemeral events of resource hyperabundance that can represent important feeding opportunities for consumers. To capitalize on pulsed resources, consumers can exhibit behavioural and physiological traits including binge‐feeding and phenotypic plasticity of digestive physiology, although expression of these ...

Método de Levantamento Topo-Batimétrico do Perfil do Sistema Praia-Antepraia

open access: yesRevista Brasileira de Geomorfologia, 2004
É apresentada uma metodologia de levantamento topo-batimétrico visando o acoplamento do perfil da praia ao perfil submarino da antepraia, a partir de um mesmo datum vertical de referência em terra, transposto por nivelamento para o ajuste do ecobatimetro,

Evaluating Conflict, Interest Advancement, and Representation in Collaborative Governance

open access: yesPublic Administration, EarlyView.
ABSTRACT Representation, conflict among stakeholders, and how both shape outputs are of growing interest in collaborative governance research. As individuals negotiate diverse viewpoints, conflict is expected, yet gaps remain in understanding if conflict, or lack thereof, helps explain output prioritization.

Intercontinental height datum connection with GOCE and GPS-levelling data

open access: yesJournal of Geodetic Science, 2012
In this study an attempt is made to establish height system datum connections based upon a gravity field and steady-state ocean circulation explorer (GOCE) gravity field model and a set of global positioning system (GPS) and levelling data. The procedure

Evaluation of grace-based combined geopotential model over the Baltic countries

open access: yesGeodesy and Cartography, 2012
Nowadays, many geodetic and engineering applications require that the two essential components of the vertical positioning – the height and the corresponding reference surface (geoid), are determined precisely.

Utilizing Airborne LiDAR and UAV Photogrammetry Techniques in Local Geoid Model Determination and Validation

open access: yesISPRS International Journal of Geo-Information, 2020
This investigation evaluates the performance of digital terrain models (DTMs) generated in different vertical datums by aerial LiDAR and unmanned aerial vehicle (UAV) photogrammetry techniques, for the determination and validation of local geoid models ...

Shorebird responses to fine‐scale water level fluctuations and macrofauna biomass in a newly constructed freshwater wetland

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Restoration of marine and freshwater wetlands for shorebirds is essential for the recovery of their declining populations. An ongoing approach is to restore shorebird habitats by large‐scale engineering, expecting the return of birds once suitable abiotic conditions are (re)established.

A restriction isomorphism for cycles of relative dimension zero

open access: yes, 2016
We study the restriction map to the closed fiber of a regular projective scheme over an excellent henselian discrete valuation ring, for a cohomological version of the Chow group of relative zero-cycles. Our main result extends the work of Saito--Sato to

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs

open access: yesSedimentology, EarlyView.
ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

WAVE EQUATION DATUMING TO CORRECT TOPOGRAPHY EFFECT ON FOOTHILL SEISMIC DATA

open access: yesEarth Sciences Research Journal, 2005
The current seismic processing applies Static Corrections to overcome the effects associated to rough topography, based in the assumption that velocity in near surface is lower than in the substratum, which force going up rays travel near to vertical ...
