1/ TMS microclimate logger
After 10 years of development and testing, we published the official description of the new TMS microclimate logger. TMS logger represents substantial innovation and overcomes several major drawbacks of other available microclimate loggers. TMS logger accurately measures air, surface and soil temperature, and soil moisture and has an extremely large memory and durable batteries. TMS logger is therefore highly suitable for long-term microclimate measurements in demanding field conditions.
TMS microclimate logger resembles a small herbaceous plant. This original design thus allows measuring air and soil temperatures and soil moisture at the plant-relevant scale.

2/ Life and death of Picea abies after bark-beetle outbreak
Large-scale stand-replacing disturbances are increasingly frequent, especially in vast coniferous forests of the Northern Hemisphere. Despite ongoing intensive research we still lack studies that disentangle processes driving forest regeneration and facilitate decision-making of forest managers, who are responsible for post-disturbance stand recovery. We followed the fate of 2552 individual seedlings for 12 years after a large-scale bark-beetle outbreak that caused complete canopy dieback in mountain Norway spruce (Picea abies) forests in SE Germany. We showed that most seedlings originated directly within the three-year dieback of canopy trees induced by bark-beetle outbreak. Our study thus highlights the so far unrecognized importance of “disturbance-related” regeneration at the expense of advance regeneration for stand recovery after bark-beetle outbreaks. We also showed that seedling mortality, and not the seedling growth rate, is the key process behind microsite specificity for tree regeneration.
