Modeling groundwater flow in bedrock can be particularly challenging due to heterogeneities associated with fracture zones. However, fracture zones can be difficult to map, particularly in forested areas where tree cover obscures land surface features ...

Estimating the spatial and temporal distribution of species richness within Sequoia and Kings Canyon National Parks. [PDF]
Evidence for significant losses of species richness or biodiversity, even within protected natural areas, is mounting. Managers are increasingly being asked to monitor biodiversity, yet estimating biodiversity is often prohibitively expensive.

Rapid submarine ice melting in the grounding zones of ice shelves in West Antarctica. [PDF]
Enhanced submarine ice-shelf melting strongly controls ice loss in the Amundsen Sea embayment (ASE) of West Antarctica, but its magnitude is not well known in the critical grounding zones of the ASE's major glaciers.

Experimental salt marsh islands: a model system for novel metacommunity experiments [PDF]
Shallow tidal coasts are characterised by shifting tidal flats and emerging or eroding islands above the high tide line. Salt marsh vegetation colonising new habitats distant from existing marshes are an ideal model to investigate metacommunity theory ...

VARIATION IN THE FLOWERING PHENOLOGY OF AN EPIPHYTIC BROMELIAD ALONG AN ELEVATIONAL GRADIENT
Elevational patterns in flowering phenology have been reported for trees, shrubs and herbs. However, for vascular epiphytes that rely on atmospheric sources for humidity and nutrients, and depend on phorophyte microhabitat, elevational patterns of ...

DIGITAL EXTRACTION AND CHANGE ANALYSIS OF ALTITUDINAL NATURAL ZONES IN TIANSHAN TOMUR NATURAL HERITAGE SITE [PDF]
The Tomur Natural Heritage Site possesses the most typical altitudinal natural zones on the south slope of the Tianshan Mountains. Five altitudinal zones have developed on the south faced slope, including: warm temperate desert zone, mountain steppe zone,

Agroecological, climatic, land elevation and socio-economic determinants of pesticide use at the farm level in Bangladesh [PDF]
This study examines the influence of agroecology, climate, land elevation and socio-economic factors on pesticide use at the farm level using a large survey data of 2083 farms from 17 districts covering 10 agroecological zones in Bangladesh by applying a

A phased creation of digital elevation model for hydrodynamic modeling in flat zones
Hydrodynamic modeling of rivers with flood simulation requires an accurate description of the riverbed and inundation morphology. Depending on a geodetic survey method and data collected, the digital elevation models with different accuracy can be created.
