Leaf area index (LAI) has frequently been measured in the field using traditional optical methods such as digital hemispherical photography (DHP). However, DHP retrieved LAI, there is always contribution of woody components due to difficulty distinguishing and foliar materials. In addition, leaf angle distribution which strongly affects estimation LAI either ignored while convergent 57.5°, or inversed simultaneously with multiple directions. Terrestrial laser scanning (TLS) provides a...
Abstract The greatest threat to the protected Eurasian lynx ( Lynx ) in Central Europe is human‐induced mortality. As availability of prey often peaks human‐modified areas, have balance successful hunting with risk encounters humans. We hypothesized that minimize this by adjusting habitat choices phases day and over seasons. predicted (1) due avoidance human‐dominated areas during daytime, range use higher at nighttime, (2) drives selection night, whereas high cover, terrain inaccessibility,...
With the launch of Sentinel-2 satellites, a European capacity has been created to ensure continuity Landsat and SPOT observations. In contrast previous sensors, Sentinel-2′s multispectral imager (MSI) incorporates three additional spectral bands in red-edge (RE) region, which are expected improve mapping vegetation traits. The objective this study was compare MSI Landsat-8 OLI data for estimation leaf area index (LAI) temperate, deciduous broadleaf forests. We used hemispherical photography...
Restricting movements to familiar areas should increase individual fitness as it provides animals with information about the spatial distribution of resources and predation risk. While benefits familiarity for locating have been reported previously, potential value avoidance has accorded less attention. It suggested that be beneficial anti-predator behaviour when direct cues risk are unclear do not allow prey identify well-defined refuges. However, our knowledge, this hypothesis yet tested....
Abstract Survival and cause‐specific mortality rates are vital for evidence‐based population forecasting conservation, particularly large carnivores, whose populations often vulnerable to human‐caused mortalities. It is therefore important know the relationship between anthropogenic natural causes evaluate whether they additive or compensatory. Further, relation survival environmental covariates could reveal specific landscape characteristics influence demographic performance. We used...
The quantification of leaf area index (LAI) is essential for modeling the interaction between atmosphere and biosphere. airborne LiDAR has emerged as an effective tool mapping plant (PAI) in a landscape consisting both woody materials. However, discrimination materials estimation LAI (eLAI) have, to date, rarely been studied at scale. We applied voxel matching algorithm estimate eLAI deciduous forests using simulated field data under leaf-on leaf-off conditions. classified points either or...
Abstract Large carnivores promote crucial ecosystem processes but are increasingly threatened by human persecution and habitat destruction. Successful conservation of this guild requires information on long-term population dynamics obtained through demographic surveys. We used camera traps to monitor Eurasian lynx between 2009 2018 in a strictly protected area the Bohemian Forest Ecosystem, located core distribution Bohemian–Bavarian–Austrian population. Thereby, we estimated sex-specific...
ABSTRACT Robust monitoring, providing information on population status, is fundamental for successful conservation planning. However, this can be hard to achieve species that are elusive and occur at low densities, such as felids. These often keystones of functioning ecosystems threatened by habitat loss human persecution. When individually identified visible characteristics, example via camera‐trapping, observations individuals used in combination with capture–recapture methods calculate...
Scavengers benefit from carrion and simultaneously provide essential ecosystem services. To assess benefits risks that might bring, it is crucial to understand ecosystem-specific scavenger communities. Carrion research has mostly focussed on ungulate carcasses rarely explored the effects of carnivore carcasses, which can be critical understanding disease transmission pathways. Therefore, using red fox, roe deer we investigated factors affect facultative vertebrate assemblages visiting...
Abstract Conservation genetics can provide data needed by conservation practitioners for their decisions regarding the management of vulnerable or endangered species, such as sun bear Helarctos malayanus . Throughout its range, is threatened loss and fragmentation habitat illegal trade both live bears parts. Sharply declining population numbers sizes, a lack natural dispersal between populations all threaten genetic diversity remaining this species. In first study using microsatellite...
Many felid species are of high conservation concern, and with increasing human disturbance the situation is worsening. Small isolated populations at risk genetic impoverishment decreasing within-species biodiversity. Movement known to be a key behavioural trait that shapes both demographic dynamics affects population survival. However, we have limited knowledge on how different manifestations movement behaviour translate processes. In this study, aimed 1) understand potential effects...
Abstract High human‐caused mortality due to wildlife‐vehicle‐collisions and illegal killing leads frequent cases of orphaned Eurasian lynx juveniles. Under natural conditions, this would result in starvation the young. To avoid this, wildlife managers conventionally rear animals captivity release them later. However, measure is an undesirable outcome for species conservation, managers, alike. Increased awareness by means must often intervene endangered populations. In study, we report first...
<title>Abstract</title> Wildlife tagging provides critical insights into animal movement ecology, physiology, and behavior amid global ecosystem changes. However, the stress induced by capture, handling, can impact post-release locomotion activity and, consequently, interpretation of study results. We analyzed post-tagging effects on 1585 individuals 42 terrestrial mammal species using collar-collected GPS accelerometer data. Species-specific displacements overall dynamic body acceleration,...
Abstract The estimation of foraging parameters is fundamental for understanding predator ecology. Predation and feeding can vary with multiple factors, such as prey availability, presence kleptoparasites human disturbance. However, our knowledge mostly limited to local scales, which prevents studying effects environmental factors across larger ecological gradients. Here, we compared inter‐kill intervals handling times Eurasian lynx ( Lynx ) a large latitudinal gradient, from subarctic the...

Abstract Large carnivores are crucial for ecosystems but increasingly threatened by human persecution and habitat destruction. Successful conservation of this guild requires information on long-term population dynamics through the demographic surveys. We camera trapped Eurasian lynx between 2009 2018 in two strictly protected areas Bohemian Forest Ecosystem, estimating sex-specific parameters using spatial capture-recapture (SCR) models as well relative abundance index its prey species a...
Leaf angle distribution (LAD) is an important canopy structure metric. It controls the flux of radiation, carbon and water, has therefore been used in many radiative transfer, meteorological hydrological models. However, LAD too tedious to measure using conventional manual methods. Terrestrial laser scanning (TLS) recently proposed estimate due its ability record unprecedented detailed plant 3D structure. previous research was restricted a controlled environment with simple In this research,...
