Impacts of precipitation and temperature on crop yields in the Pampas por Veron, Santiago Ramón, De Abelleyra, Diego, Lobell, David B.

“…A parallel analysis was conducted on a per county basis by adjusting a linear model to the first difference (i.e., subtracting from each value the previous year value) in yield and first difference in weather variables to estimate crop sensitivity to interannual changes in P, T, and DTR. …”

Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey por Kymmell, David

“…I tested the relations between these variables using a multiple regression analysis with zero‐inflated generalized linear models. Results & discussion: In two of the three areas I did not find a difference in patch utilization between the burned and the control site for mountain hare. …”

Environmental and genetic parameters of growth, reproductive and survival performance of Afar and blackhead Somali sheep at Werer Agricultural Research Centre, Ethiopia por Yacob, Y.

“…Data collected on flocks of Afar (1976 to 1991) and Black Head Somali (1977 to 1987) at Were research center were used to study the effect of environmental factors on ewe reproductive performance, lamb survival and early growth traits (Birth, weaning, six month and yearling and pre and post-weaning daily gain) in addition genetic analyses were carried out to estimate genetic parameters (heritability, repeatability and genetic and phenotypic correlations) for early growth traits. General linear model procedures were used in the non-genetic analysis using a linear model that included the effect of year, sex, type of birth, parity, ewe age, and ewe and sire body weights at mating and their possible interactions for all traits plus regressions on age at weaning, six-month and yearling weights. …”

Prevalence and risk factors for shedding of Cryptosporidium spp. oocysts in dairy calves of Buenos Aires Province, Argentina por Garro, Carlos Javier, Morici, Gabriel Edgardo, Utges, María E., Tomazic, Mariela Luján, Schnittger, Leonhard

“…Putative risk factors were tested for association using generalized linear mixed models (GLMMs). Oocyst shedding calves were found in 67% (CI95% = 49–84) of herds (corresponding to a true herd prevalence of 98%) and 16% (CI95% = 13–19) of calves (corresponding to a true calve prevalence of 8%). …”

Combined application of the EM-DEA and EX-ACT approaches for integrated assessment of resource use efficiency, sustainability and carbon footprint of smallholder maize production p... por Mwambo, F.M., Fürst, C., Martius, C., Jiménez Martinez, M., Nyarko, B.K., Borgemeister, C.

“…However, the relationship between the yield and urea intensity was not always linear. A system that used more renewable or fewer resources to produce a yield equal to that of its peer was considered more efficient and sustainable in relative terms. …”

Frog body condition: Basic assumptions, comparison of methods and characterization of natural variability with field data from Leptodactylus Latrans por Brodeur, Celine Marie, Damonte, María Jimena, Vera Candioti, Josefina, Poliserpi, Maria Belen, D´andrea, María Florencia, Bahl, María Florencia

“…A truly size-independent SMI value was more easily obtained when defining the scaling exponent through a non-linear regression of mass on length rather than when performing a standardized major axis regression of lnweight on lnlength. …”

Dominance and rarity in tree communities across the globe: patterns, predictors and threats por Hordijk, Iris, Bialic-Murphy, Lalasia, Lauber, Thomas, Routh, Devin, Poorter, Lourens, Rivers, Malin C., Steege, Hans ter, Liang, Jingjing, Reich, Peter B., de-Miguel, Sergio, Peri, Pablo Luis, Crowther, Thomas W.

“…We mapped global community dominance and rarity using machine learning models and evaluated the ecological and anthropogenic predictors with linear models. Extinction risk, for example threatened status, of geographically widespread dominant and rare species was evaluated. …”

Plant spacing assessment in cocoa (Theobroma cacao L.) agroforestry systems in the Colombian Pacific region por Perez Zuñiga, Jose Ives, Rojas Molina, Jairo, Zabala Perilla, Andrés Felipe

“…In the second phase, an analysis of optimal plant spacing was conducted using the results from the characterization phase. Thus, a linear programming model was developed that utilizes the three plant densities most used by producers (3x3 m, 3.5x3.5 m, and 4x4 m). …”
