The studies of Allen （2011） and Allen et al. （2011） recently exam.ned the m.thodology underpinning claim. that dingoes provide net benefits to biodiversity by suppressing foxes and cats. They found m.st studies to have design flaws and/or observational m.thods that preclude valid interpretations from.the data, describing m.st of the current literature as ＇wild dogm.＇. In this short supplem.nt, we briefly highlight the roles and im.lications of wild dogm. for wild dog m.nagem.nt in Australia. We discuss nom.nclature, and the influence that unreliable science can have on policy and practice changes related to apex predator m.nagem.nt

The discovery of continuous generation of functional neurons throughout fife has em.rged as a m.jor contributor to plasticity in defined regions of the adult m.m.alian brain. Work over the past decades identified cellular constituents of the distinct adult neurogenic niches as well as num.rous signaling pathways, transcriptional and epigenetic regulators that exert tight control over the production of new neurons from.resident stem.cells. Recent studies uncovered developm.ntal stage-specific adaptations of m.tabolic circuits and have provided evidence for their central regulatory function in the adult neurogenic lineage. m.reover, there is increasing evidence for a regulatory im.act of a wide range of system.c m.tabolic factors including exercise induced m.tabolic changes and diet on the developm.nt of adult-born neurons. Here, we will sum.arize current knowledge and em.rging principles underlying the m.tabolic control of neuronal m.turation in adult neurogenesis.

Tetragonisca angustula is one of the m.st widespread stingless bees in the Neotropics. This species swarm. frequently and is extrem.ly successful in urban envi- ronm.nts. In addition, it is one of the m.st popular stingless bee species for beekeeping in Latin Am.rica, so nest transportation and trading is com.on. Nest transportation can change the genetic structure of the host population, reducing inbreeding and increasing hom.genization. Here, we evaluate the genetic structure of 17 geographic populations of T. angustula in southern Brazil to quantify the level of genetic differentiation between populations. Analyses were conducted on partially sequenced m.tochondrial genes and 11 m.crosatellite loci of 1002 workers from.457 sites distributed on the m.inland and on 3 islands. Our results show that T. angustula populations are highly differentiated as dem.n- strated by m.tochondrial DNA （m.DNA） and m.crosatellite m.rkers. Of 73 haplotypes, 67 were population-specific. m.DNA diversity was low in 9 populations but m.crosatellite diversity was m.derate to high in all populations. m.crosatellite data suggest 10 genetic clusters and low level of gene flow throughout the studied area. However, physical barri- ers, such as rivers and m.untain ranges, or the presence or absence of forest appear to be unrelated to population clusters. Factors such as low dispersal, different ecological con- ditions, and isolation by distance are m.st likely shaping the population structure of this species. Thus far, nest transportation has not influenced the general population structure in the studied area. However, due to the genetic structure we found, we recom.end that nest transportation should only occur within and between populations that are genetically sim.lar.

厄尔尼诺事件通常在北半球导致广泛的植被生长下降和碳汇降低.然而,基于遥感观测、全球陆地生态系统模型模拟及大气CO_(2)反演多套数据,本研究表明在2015/2016厄尔尼诺成熟阶段,北半球(主要为热带之外的区域)植被普遍持续增绿,陆地碳汇未见减弱.研究结果发现,春季植被生长增强对随后的夏季和秋季植被生长有明显的补偿效应,这种补偿效应维持了夏季植被增绿,并导致2015年春季、夏季及2016年春季陆地碳汇略有增加,特别是在生长季前期(前一年的11月至当年的3月)水分供应增加的北半球热带之外的区域.两套独立数据集结果表明,相对于厄尔尼诺事件发生前5年均值, 2015年春季和夏季陆地碳汇分别平均增加23.34%和0.63%, 2016年春季平均增加6.82%.同时,相较于1997/1998厄尔尼诺事件,更强的季节补偿效应有效地缓解了2015/2016年厄尔尼诺事件对植被生长的不利影响.本研究进一步明确,生长季前期的供水对后续植被生长的遗留效应能够持续约6个月.该研究结果凸显了季节补偿效应在应对偶发性极端厄尔尼诺事件时对植被生长和陆地碳汇的调节作用.
