UAVs unveil the role of small scale vegetation structure on wader nest survival

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
In this study, we combine high‐resolution vegetation structural metrics derived from unmanned aerial vehicle (UAV) imagery with on‐field wader nest survival monitoring. We show that the immediate vegetation height and heterogeneity within a 2‐meter buffer surrounding the clutch of the recorded ground‐nesting wader species positively influenced its ...

Throughfall and temporal trends of rainfall redistribution in an open tropical rainforest, south-western Amazonia (Rondônia, Brazil)

open access: yes, 2005
International audienceThroughfall volumes and incident rainfall were measured between 23 August and 2 December 2004 as well as from 6 January to 15 April 2005 for individual rain events of differing intensities and magnitudes in an open tropical ...

Rainfall partitioning in mixed oak forest with dwarf bamboo (Sasa paniculata) undergrowth. [PDF]

open access: yes, 1996
Throughfall measurements in a 60-year-old white oak (Konara) stand (Quercus serrata THUNB.) with under growing dwarf bamboo (Sasa paniculata) were carried out during two periods totaling eleven months, from August to November 1993 and from May to ...

Programmed unmanned aerial vehicles show great potential for monitoring marine megafauna in specific areas of interest

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

SWAP Version 3.2. Theory description and user manual [PDF]

open access: yes
SWAP 3.2 simulates transport of water, solutes and heat in the vadose zone. It describes a domain from the top of canopy into the groundwater which may be in interaction with a surface water system.

Fungsi Hidrologi Kebun Karet (Hevea Brasiliensis Muell. Arg) Dalam Mereduksi Besaran Curah Hujan Bersih (Hydrological Function of Rubber Plantation (Hevea Brasiliensis Muell. Arg) to Reducing the Magnitude of Net Rainfall) [PDF]

open access: yes, 2012
Forest conversion resulted in loss of various forest functions, mainly the hydrological function changes. Mostly of the conversion of forests were to be oil palm and rubber plantations.

Hyperspectral species maps and LiDAR‐based structured population models show future forest fire frequency may compromise forest resilience

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Monitoring forest recovery from disturbances at scale requires tracking tree dynamics, yet traditional ground‐based approaches are resource‐intensive. We present a pipeline to parameterize integral projection models (IPMs) using LiDAR data and hyperspectral‐based species maps to assess post‐fire recovery across large, forested areas at the Caribou ...

The Montado agroforestry system microclimatic specificity in the context of global change [PDF]

open access: yes, 2009
The effects of oak trees on microclimatic parameters in Quercus rotundifolia Lam. woodland in the Alentejo, Southern Portugal, are reported. Results show that oak tree create a marked differentiation in the grass matrix, between open and undercanopy ...

Monitoring feral pigs (Sus scrofa): Complementarity between autonomous sensing methods increases detection probability

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Invasive alien species are a major threat for biodiversity worldwide and effective monitoring is paramount to inform management. In this study we used a multi‐season occupancy model to assess probability of detection between camera traps and passive acoustic recorders for feral pigs (Sus scrofa) during 1 year of data collection.
