Therefore, how to precisely model the tropospheric biases is very critical and challenging for long baseline precise RTK with triple-frequency GNSS signals.
We additionally selected the HoxD locus, a GC-rich target that is challenging for long PCR and unusually depleted in repetitive sequences [Greally, 2002], as well as an interval from the MHC class II region that was well characterized in the semen donor selected for the survey [Kauppi et al., 2003, 2004, 2005; Jeffreys et al., 2001].
The lack of precise, consistent and up-to-date forest details is challenging for long-term prognoses.
Determining how ecological filters (e.g., climate, soils, biotic interactions) influence where species succeed in heterogeneous landscapes is challenging for long-lived species (e.g., trees), because filters can vary over space and change slowly through time.
