Diversity of scale insects (Hemiptera, Coccomorpha) in ten varieties of olive trees (Olea europaea L.) in Southern Brazil Anais da ABC (AABC)
WOLFF,VERA R.S.; EFROM,CAIO F.S.; SILVA,DANIELE C. DA; TONIETTO,ADILSON.
Abstract Olive production (Olea europaea L.) is a recent activity in Brazil and studies on the adaptability of olive trees varieties in the States are required. One of the problems that can hamper the development of olive trees is the incidence of pests, such as scale insects (Hemiptera, Coccomorpha). In this study, the associated scale insect species were found in ten varieties in an olive grove located at the Research Center of the Serra do Sudeste Region (30º33’15”S, 52º23’45”W) in Brazil. The surveys were carried out twice in each season (2013-2014). Six species of armored scale insect (Diaspididae) and two soft scales (Coccidae) were determined. Saissetia oleae (Coccidae) with 88.15% and Aspidiotus nerii (Diaspididae) with 5.85% occurred in all...

Stability and adaptability analysis of Tabapuã bulls for performance traits according to the herd level Arq. Bras. Med. Vet. Zootec.
Marçal,M.F.; Ferraz Filho,P.B.; Souza,J.C.; Silva,L.O.C.; Gomes,F.J.; Freitas,J.A..
In order to study the stability and adaptability of Tabapuã cattle for the characteristic weight at 120 days of maternal effect, we used methods based on linear regression. The analysis included differences in the expected progeny of five sire sin herds located in four farms in the states of Bahia, (herds 1and 2), Paraná (herd 3) and Minas Gerais (herd 4). The results show that the performance of bulls depend largely on the genetic variability of the matrices for different characteristics in herds studied, allowing the recommendation of a specific breeding herd. Analyses of adaptability and stability discriminated performance differences in herds. Bulls were identified as adapted and perfectly stable, bulls with general adaptation, and with specific...

Prediction of Hevea progeny performance in the presence of genotype-environment interaction BABT
Gonçalves,Paulo de Souza; Moraes,Mário Luiz Teixeira de; Silva,Marcelo de Almeida; Gouvêa,Lígia Regina Lima; Aguiar,Adriano Tosoni da Eira; Costa,Reginaldo Brito da.
Twenty two open-pollinated Hevea progenies from different parental clones of the Asian origin were tested at five sites in the Northwestern São Paulo State Brazil to investigate the progeny girth growth, rubber yield, bark thickness and plant height. Except for the rubber yield, the analysis of variance indicated highly significant (p<0.01) genotype x environment interaction and heterogeneity of regressions among the progenies. However, the regression stability analysis identified only a few interacting progenies which had regression coefficients significantly different from the expected value of one. The linear regressions of the progeny mean performance at each test on an environmental index (mean of all the progenies in each test) showed the general...

Visualizing Adaptation of Genotypes with a Ternary Plot Chilean J. Agric. Res.
Kozak,Marcin.
Adaptation can be studied through various methods, some of which are based on adaptation or stability measures while others on complex models and graphs. In this adaptation measure based on quantiles is presented; the measure is three-dimensional and can be pictured with a ternary (trilinear) plot. A simple algorithm for constructing such a plot is presented and the interpretation of the plot is discussed. By means of this graphical tool one can picture and interpret the specific and wide adaptation of genotypes to environments, offering complementary information to that of other methods of analyzing genotype-by-environment data.

Factor analysis and SREG GGE biplot for the genotype × environment interaction stratification in maize Ciência Rural
Fritsche-Neto,Roberto; Miranda,Glauco Vieira; DeLima,Rodrigo Oliveira; Souza,Heraldo Namorato de.
The objective of this study was to evaluate the use of SREG GGE biplot methodology and factor analysis to stratify the genotype×environment interaction in maize. Forty-nine early maize hybrids were evaluated in nine environments. The experimental design used was a 7×7 square lattice with two replicates. Each plot consisted of two 5m long rows spaced 0.90m apart. Grain yield data were used to perform the analysis. The results indicated the existence of two mega-environments in the State of Minas Gerais, Brazil, for early maize hybrids. The stratification of the environment by factor analysis was more selective to join the similarity the according with cultivar performance. However, this approach did not identify specific genotype x environment interactions,...

ABSTRACT: Using genotypes adapted to different regions is one of the main ways to increase Brazilian bean yield. The aim of the present study was to assess the genotypic performance of Carioca beans through mixed models. Fourteen Carioca bean genotypes were assessed in four locations in Pernambuco State (Arcoverde, Caruaru, Belém de São Francisco and São João counties) in 2015. The experiments followed a completely randomized block design, with three repetitions. Genetic parameters were estimated according to the REML/BLUP methodology, whereas genotype selection was based on the harmonic mean of relative performance of genetic values method (MHPRVG). The mean genotype heritability had moderate magnitude, high selective accuracy, besides allowing selection...

Social-Ecological Transformation for Ecosystem Management: the Development of Adaptive Co-management of a Wetland Landscape in Southern Sweden Ecology and Society
Olsson, Per; Center for Transdisciplinary Environmental Research; potto@system.ecology.su.se; Folke, Carl; ;; Hahn, Thomas; ;.
We analyze the emergence of an adaptive co-management system for wetland landscape governance in southern Sweden, a process where unconnected management by several actors in the landscape was mobilized, renewed, and reconfigured into ecosystem management within about a decade. Our analysis highlights the social mechanisms behind the transformation toward ecosystem management. The self-organizing process was triggered by perceived threats among members of various local stewardship associations and local government to the area&#8217;s cultural and ecological values. These threats challenged the development of ecosystem services in the area. We show how one individual, a key leader, played an instrumental role in directing change and transforming...

Resilience Thinking: Integrating Resilience, Adaptability and Transformability Ecology and Society
Folke, Carl; Stockholm Resilience Centre, Stockholm University; Beijer Institute of Ecological Economics, Royal Swedish Academy of Sciences; carl.folke@beijer.kva.se; Carpenter, Stephen R; Center for Limnology, University of Wisconsin; srcarpen@wisc.edu; Walker, Brian; CSIRO Sustainable Ecosystems; Stockholm Resilience Centre, Stockholm University; Brian.Walker@csiro.au; Scheffer, Marten; Aquatic Ecology and Water Quality Management Group, Wageningen Agricultural University; Marten.Scheffer@wur.nl; Chapin, Terry; Institute of Arctic Biology, University of Alaska Fairbanks; fschapiniii@alaska.edu.
Resilience thinking addresses the dynamics and development of complex social&#8211;ecological systems (SES). Three aspects are central: resilience, adaptability and transformability. These aspects interrelate across multiple scales. Resilience in this context is the capacity of a SES to continually change and adapt yet remain within critical thresholds. Adaptability is part of resilience. It represents the capacity to adjust responses to changing external drivers and internal processes and thereby allow for development along the current trajectory (stability domain). Transformability is the capacity to cross thresholds into new development trajectories. Transformational change at smaller scales enables resilience at larger scales. The capacity to...

Prescriptions for adaptive comanagement: the case of flood management in the German Rhine basin Ecology and Society
Becker, Gert; VU University Amsterdam, Institute for Environmental Studies; g.becker@vu.nl; Huitema, Dave; VU University Amsterdam, Institute for Environmental Studies; Netherlands Open University, Faculty of Management, Science and Technology; dave.huitema@ivm.vu.nl; Aerts, Jeroen C.J.H.; VU University Amsterdam, Institute for Environmental Studies; jeroen.aerts@vu.nl.
Centrally administered bureaucracies are ill suited to managing the environmental resources of complex social-ecological systems. Therefore management approaches are required that can better deal with its complexity and uncertainty, which are further exacerbated by developments such as climate change. Adaptive comanagement (ACM) has emerged as a relatively novel governance approach and potential solution to the challenges arising. Adaptive comanagement hinges on certain institutional prescriptions intended to enhance the adaptability of management by improving the comprehension of and response to the complex context and surprises of social-ecological systems. The ACM literature describes that for enhanced adaptability, institutional arrangements should be...

Relationship between leaf stages and epistasis for resistance to Stagonospora nodorum in durum wheat Genet. Mol. Biol.
Bnejdi,Fethi; Saadoun,Mourad; Naouari,Mouna; El Gazzah,Mohamed.
Ten varieties and eight generations (2F1, 2F2, 2B1 and 2B2) of durum wheat derived from two crosses were evaluated for resistance to natural infection by Stagonospora nodorum blotch (SNB) at the 2-3 and 6-7 leaf stages at two sites over two years. There were significant differences in the incidence of SNB between leaf stages in most of the wheat varieties, with resistance being most evident at the 6-7 leaf stage. Separate analyses of the mean values for each generation showed that the genetic mechanism of defense against the pathogen depended upon the leaf stage. At the 2-3 leaf stage, only additive and dominance effects were implicated in the control of SNB for the two crosses at the two sites and for the two replications. For the 6-7 leaf stage,...

People and the changing nature of coral reefs ArchiMer
Hoegh-guldberg, Ove; Pendleton, Linwood; Kaup, Anne.
Coral reefs are biodiverse and productive ecosystems but are threatened by local and global stresses. The resulting loss of coral reefs is threatening coastal food and livelihoods. Climate projections suggest that coral reefs will continue to undergo major changes even if the goals of the Paris Agreement (Dec 2015) are successfully implemented. Ecological changes include modified food webs, shifts in community structure, reduced habitat complexity, decreased fecundity and recruitment, changes to fisheries productivity/opportunity, and a shift in the carbonate budget of some ecosystems toward dissolution and erosion of calcium carbonate stocks. Broad estimates of the long-term (present value) of services provided by the ocean’s ecological assets exist and...

Nesting ecology of a neotropical solitary wasp (Hymenoptera: Sphecidae) in Panamá Neotropical Entomology
Giovanetti,Manuela.
Cerceris is a very interesting genus, providing species living in all continents, in different climatic conditions, showing behaviors ranging from solitary to social. About the nesting habit of this genus, many authors described nest characteristics and prey, providing useful material for comparison. Yet, the majority of species studied so far live in temperate regions and we lack information about the tropical ones. The high number of species and their wide distribution suggest a phylogenetic adaptability that merit to be studied deeper. I investigated nest and prey of a tropical species, Cerceris binodis Spinola, on Barro Colorado Nature Monument in Panamá. The study was performed during three dry seasons, marking and excavating nests, observing...

Multivariate analyses of genotype x environment interaction of popcorn PAB
Miranda,Glauco Vieira; Souza,Leandro Vagno de; Guimarães,Lauro José Moreira; Namorato,Heraldo; Oliveira,Lucimar Rodrigues; Soares,Marcelo Oliveira.
The objectives of this work were to evaluate the genotype x environment (GxE) interaction for popcorn and to compare two multivariate analyses methods. Nine popcorn cultivars were sown on four dates one month apart during each of the agricultural years 1998/1999 and 1999/2000. The experiments were carried out using randomized block designs, with four replicates. The cv. Zélia contributed the least to the GxE interaction. The cv. Viçosa performed similarly to cv. Rosa-claro. Optimization of GxE was obtained for cv. CMS 42 for a favorable mega-environment, and for cv. CMS 43 for an unfavorable environment. Multivariate analysis supported the results from the method of Eberhart &amp; Russell. The graphic analysis of the Additive Main effects and...

Key locations for soybean genotype assessment in Central Brazil PAB
Pacheco,Roberto Miranda; Duarte,João Batista; Souza,Plínio Itamar Mello de; Silva,Sérgio Abud da; Nunes Junior,José.
The objective of this work was to identify key locations for the establishment of soybean (Glycine max) genetic breeding programs, in the Central Region of Brazil. Grain yield data of three maturity groups of soybean genotypes, from regional trials conducted over three years, at 18 locations in Brazilian Cerrado were used. A key location for the early phases of the breeding program was defined as the site that best classifies the winning genotypes in the region. Key locations for the final phases were defined as those sites that best represent each environmental stratum, in relation to the adaptability of the respective winning genotype. This adaptability was estimated by additive main effects and multiplicative interaction (AMMI) model analysis, using the...
