Tree growth is better explained by absorptive fine root traits than by transport fine root traits.

Although the interest in root traits has increased in recent years, we still have limited knowledge of (i) whether functionally different fine roots-absorptive versus transport roots-have similar trait coordination and (ii) how they help to explain plant performance, such as growth. We measured traits of 25 European broadleaved tree species growing in a research arboretum to study (i) the coordination of root traits within absorptive and transport fine roots and (ii) the degree of trait-tree growth relationships. To do so, we combined a suite of morphological and anatomical traits for each of the absorptive and transport roots.

Anthropogenic Impacts on Coral-Algal Interactions of the Subtropical Lagoonal Reef, Norfolk Island.

Reef building corals are important in subtropical marine ecoregions, shaping ecosystems and providing habitats for fish and benthic species. Algal communities contribute substantially to the benthic population structure across subtropical coral reefs, however increasing algal cover on subtropical reefs is also linked to degraded ecosystems as has been shown on tropical systems. As such, the dynamics of coral-algal interactions on subtropical reefs are also likely to be an indicator of ecosystem health on subtropical ecosystems.

Promoting Reasonable Career Expectations and Maximizing Professional Fulfillment for Academic Oncologists: ASCO Recommendations for Academic Medical Centers.

In this statement, ASCO encourages academic medical centers to change their policies and expectations to enhance and promote the professional fulfillment of academic medical oncologists. The statement includes three recommendations directed to academic medical centers to further this goal: (1) establish reasonable clinical workloads for academic medical oncologists, (2) provide resources to enable medical oncologists to participate in and conduct research, and (3) develop and apply their standards for clinical workloads and research support, as well as career advancement and leadership opportunities, fairly and equitably across academic medical oncologists. Overall, improved career satisfaction is likely to result in retention of oncologists in the workforce.

Methane emissions from the Nord Stream subsea pipeline leaks.

The amount of methane released to the atmosphere from the Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range of estimates. A lack of information regarding the temporal variation in atmospheric emissions has made it challenging to reconcile pipeline volumetric (bottom-up) estimates with measurement-based (top-down) estimates. Here we simulate pipeline rupture emission rates and integrate these with methane dissolution and sea-surface outgassing estimates to model the evolution of atmospheric emissions from the leaks.
