Flashcards in Monitoring Biodviersty Deck (76)
Why do we monitor
Changes over time to stress. (Climate change)
Responses to specific interventions. (Wild fire management)
Recovery of a species (reintrudrion)
Why can biodiversity itself not be applied to real world problems
It is too broad and vague a concept
Why is biodiversity so broad
It’s the number of genes, species ecosystem but also processes like interspecific interactions, natural disturbances, nutrient cycles
What are the different ways to monitoring the impacts on dendribates (frog)
Climate factors controlling vegetation and patterns of species richness across regions.
Habitat availability and landscape linkages.
Climate controls on regional and local disturbance regimes.
Physiological tolerances of individual species.
Dispersal capacities of individual species.
Genetic variations within and among different populations of a species.
What are the parts of the the conceptual figure of biodiversity
What does structural mean
Physical organisation or patterns like habitat complexity.
What does compositional mean
Identity and richness like species diversity and genetic diversity
What does functional mean
Ecological and evolutionary processes like gene flow and nutrient cyclin
What is the conceptual figure of biodiversity at the regional scale
C: distribution, richness, endemism.
S: heterogeneity, fragmentation, patch size.
F: disturbance processes, hydrological processes
What is the conceptual figure of biodiversity at the community (ecosystem scale)
C: relatively abundance and proportions of threatened species.
S: soil, vegetation, horizontal/ vertical heterogeneity.
F: herbivory, productivity.
What is the conceptual figure of biodiversity at the population (species) level
C: abundance, biomass.
S/ range, population structure.
F: population fluctuation and phenology
What is the conceptual figure of biodiversity at the genetic scale
C: allelic diversity, presence of specific alleles.
S: population size, heterozygosity.
F: inbreeding depression, geneflow.
What makes a good indicator species
Sensitive to detect change.
Widely relevant/ disturbed.
Provides continuous assessment over wide range.
Results are independent of sample size.
Easy to measure.
Differentiates between natural and anthropogenically induced change.
Relevant to ecologically significant issues.
What are the different indicators in Brazil
Birds and dung beetles are well studied and perform important ecological functions.
What does resolution do
It’s about scale and precision and tells us what tools
What are the range of methods to monitoring
Example of field measurements
Example of remote sensing
What are the analyses of monitoring
Examples of indicies
Heterogentiy, connnectivity, diversity
What are conservation drones
Low cost unmanned aerial vehicles
What do conservations drones do
Monitor and map terrestrial and aquatic ecosystems.
Support enforcement of protected areas.
Example of conservation drones
Drones to monitor organgutabs who make their nests on top of trees
What are camera traps
Remotely activated camera equipped with a motion, infrared or light sensor as a trigger
Why do we use camera traps
Detected elusive species e.g low density, nocturnal or shy. Can get to remote or inhospitable sites and good for Mark-recapture studies
Example of camera trapping
Sri Lankan leopards.
To monitor: population size and trends. Home range and territoriality. Feeding ecology. Landscape connectivity.
Why should we conserve birds and butterflies
Good indicators of environmental change.
Important to the ecosystem.
Example of a charity organisation for birds
RSPB - royal society for the protection of birds
BTo - British trust for ornithology
Facts of the RSPB
Leading charity for the last 110 years.
UK headquarters, 3 national offices, 9 regional offices, 175 local groups.
A million current members.
