A phylogeographic study of the stoneplant Conophytum (Aizoaceae; Ruschioideae; Ruschieae) in the Bushmanland Inselberg Region (South Africa) suggests anemochory
The Bushmanland Inselberg Region (BIR) of South Africa provides an ideal system to study population interactions, as these inselbergs function as islands of Succulent Karoo surrounded by Nama Karoo vegetation. The population genetics of four Conophytum taxa endemic to the quartz-associated habitats of inselbergs in the BIR were investigated using...Powell, Robyn ; Magee, Anthony ; Forest, Felix ; Cowan, Robyn ; Boatwright, Stephen

Adapting legume crops to climate change using genomic approaches
Our agricultural system and hence food security is threatened by combination of events, such as increasing population, the impacts of climate change, and the need to a more sustainable development. Evolutionary adaptation may help some species to overcome environmental changes through new selection pressures driven by climate change. However, success...Mousavi‐Derazmahalleh, Mahsa ; Bayer, Philipp ; Hane, James ; Valliyodan, Babu ; Nguyen, Henry …

Acaricidal activity of cashew nut shell liquid associated with essential oils from Cordia verbenacea and Psidium guajava on Rhipicephalus microplus
The aim of this study was to assess the effectiveness of cashew nut shell liquid (CNSL), Cordia verbenacea and Psidium guajava, both alone and in association against Rhipicephalus microplus. Larval packet and adult immersion tests were conducted in concentrations ranging from 3.1 at 100.0mg mL−1. CNSL was effective against engorged females (99.6%) at 100.0mg mL−1 and against larvae (99.2 %)...de Carvahlo Castro, K ; Costa-Júnior, L ; Lima, D ; Canuto, K ; Sousa De Brito, E …

An allometry between seed kernel and seed coat shows greater investment in physical defense in small seeds
Premise of the Study Numerous studies have treated the mass of a whole seed as an integrated unit, although the components seed kernel and seed coat play different roles and are subject to different evolutionary selection pressures. In this study, we provided the first global-scale quantification of the relative biomass...Wu, La-Mei ; Chen, Si-Chong ; Wang, Bo

Adaptive significance of functional germination traits in crop wild relatives of Brassica
Functional germination traits contribute to both niche competitiveness and crop yield outcomes. However, there is little understanding of the adaptive significance of the germination thermal- and hydro-parameters in crop wild relatives (CWRs), yet these species are anticipated to be the source of adaptive traits for future agriculture. Seeds of 10...Castillo-Lorenzo, E ; Finch-Savage, WE ; Seal, C ; Pritchard, Hugh

Ancient polyploidy and genome evolution in palms
Mechanisms of genome evolution are fundamental to our understanding of adaptation and the generation and maintenance of biodiversity, yet genome dynamics are still poorly characterized in many clades. Strong correlations between variation in genomic attributes and species diversity across the plant tree of life suggest that polyploidy or other mechanisms...Barrett, Craig ; McKain, Michael ; Sinn, Brandon ; Ge, Xue-Jun ; Zhang, Yuqu …

Advanced understanding of phylogenetic relationships, morphological evolution and biogeographic history of the mega-diverse plant genus Myrcia and its relatives (Myrtaceae: Myrteae)
Myrcia is the largest exclusively Neotropical genus of the plant family Myrtaceae with c. 770 species. Although several studies have elucidated the relationships within particular sections of the genus, to date no phylogeny has been produced that includes a broad taxonomic and geographic representation. Here we present a phylogenetic hypothesis...Amorim, Bruno ; Vasconcelos, Thais ; Souza, Gustavo ; Alves, Marccus ; Antonelli, Alexandre …

Atmospheric nitrogen deposition impacts on the structure and function of forest mycorrhizal communities: A review
Humans have dramatically increased atmospheric nitrogen (N) deposition globally. At the coarsest resolution, N deposition is correlated with shifts from ectomycorrhizal (EcM) to arbuscular mycorrhizal (AM) tree dominance. At finer resolution, ectomycorrhizal fungal (EcMF) and arbuscular mycorrhizal fungal (AMF) communities respond strongly to long-term N deposition with the disappearance of...Lilleskov, Erik ; Kuyper, Thomas ; Bidartondo, Martin ; Hobbie, Erik

Biodiversity seen through the perspective of insects: 10 simple rules on methodological choices and experimental design for genomic studies
Massively parallel DNA sequencing opens up opportunities for bridging multiple temporal and spatial dimensions in biodiversity research, thanks to its efficiency to recover millions of nucleotide polymorphisms. Here, we identify the current status, discuss the main challenges, and look into future perspectives on biodiversity genomics focusing on insects, which arguably...Matos-Maraví, Pável ; Duarte Ritter, Camila ; Barnes, Christopher ; Nielsen, Martin ; Olsson, Urban …

Belowground Biodiversity Relates Positively to Ecosystem Services of European Forests
Biodiversity of ecosystems is an important driver for the supply of ecosystem services to people. Soils often have a larger biodiversity per unit surface area than what can be observed aboveground.

C4 anatomy can evolve via a single developmental change
C4 photosynthesis is a complex trait that boosts productivity in warm environments. Paradoxically, it evolved independently in numerous plant lineages, despite requiring specialised leaf anatomy. The anatomical modifications underlying C4 evolution have previously been evaluated through interspecific comparisons, which capture numerous changes besides those needed for C4 functionality. Here, we...Lundgren, Marjorie ; Dunning, Luke ; Olofsson, Jill ; Moreno-Villena, Jose ; Bouvier, Jacques …

Coenocytic growth phases in land plant development: a paleo-evo-devo perspective
Premise of research.?The evolutionary origin of the seed habit coincided with profound physiological and structural changes associated with underlying developmental patterns. A coenocyte is formed during megagametophyte development in many vascular plants, including some lycophytes and all spermatophytes; this structure compares closely with similar free-nuclear growth phases during embryo development...Rudall, Paula ; Bateman, Richard
