Maximum Clade Credibility (MCC) tree showing clade divergence times in millions of years. Coloured squares represent ancestral ranges depicted in the map, upper left; A, Betic, B, Rifean/ Kabylia, C, Middle Atlas, D, High Atlas. Coloured branches correspond to arrows in the lower left maps (1, 2), which indicate diversification route of Magrebmelia throughout the western Mediterranean Basin since the Early Miocene [East lineage (red) and South lineage (purple)], based on biogeographical reconstructions of western Mediterranean Pimelia (MasPeinado et al., 2018). Populations morphologically assignable to P. xauenensis but related to P. mauritanica are indicated by specimen numbers. Maps 1–2 modified from Andeweg (2002); Meulenkamp & Sissingh (2003).
Thermal stabilisation of the short DNA duplexes by acridine-4-carboxamide derivatives
<p>The short oligodeoxynucleotide (ODN) probes are suitable for good discrimination of point mutations, however, they suffer from low melting temperatures. In this work, the strategy of using acridine-4-carboxamide intercalators to improve thermal stabilization is investigated. The study of large series of acridines revealed that optimal stabilization is achieved upon decoration of acridine by secondary carboxamide carrying sterically not demanding basic function bound through two-carbon linker. Presence of secondary carboxamides plays a key role in stabilization of the duplex. Two highly active intercalators were attached to short probes (13 or 18 bases; designed as a part of HFE gene) by click chemistry into positions 7 and/or 13 and proved to increase the melting temperate (T<sub>m</sub>) of the duplex by almost 8°C for the best combination. The acridines interact with both single- and double-stranded DNAs with substantially preferred interaction for the latter. The study of interaction suggested higher affinity of the acridines toward the GC- than AT-rich sequences. Good discrimination of two types of point mutations was shown.</p>

Soil carbon is mostly grass-derived in tropical savannas, even under woody encroachment
<p>Tropical savannas have been increasingly targeted for carbon (C) sequestration from afforestation, assuming large gains in soil organic C (SOC) with increasing tree cover. Because savanna SOC is also derived from grasses, this assumption may not reflect real changes in SOC under afforestation, but grass contributions to SOC and changes in SOC with increasing tree cover remain poorly synthesized. Here, we combine a case study from Kruger National Park, South Africa, with data synthesized from tropical savannas globally to show that grass-derived C constitutes more than half of total SOC to a soil depth of 1-meter, even in soils directly under trees. The largest SOC concentrations were associated with the largest grass contributions (> 70% of total SOC). Regionally and across the tropics, SOC concentration was not explained by tree cover. Both SOC gain and loss were observed following increasing tree cover, and on average SOC storage within 1-meter profile only increased by a negligible and non-significant 6% (SE = 4%, n = 44). These results underscore the substantial contribution of grasses to SOC and the considerable uncertainty in SOC responses to increasing tree cover, challenging the widespread assumption that afforestation universally and substantially enhances SOC storage across tropical savannas.</p>
