“…Aumento en el costo de producción. Debido a que se deben controlar para disminuir las pérdidas de rendimiento del cultivo, el productor debe invertir dinero en la compra de herbicidas y en la implementación de múltiples M a n u s c r i t o a c e p t a d o estrategias de manejo de malezas (Pardo et al, 2020). Entre mayor sea la magnitud del problema de malezas, mayores serán los costos de su manejo (Korres et al, 2020).…”

Introducción. La percepción de que las plantas nativas de campos agrícolas no aportan nada bueno a los sistemas productivos y deben ser eliminadas en su totalidad, ha provocado múltiples problemas agronómicos, ambientales y sociales en los agroecosistemas alrededor del mundo, tales como selección de plantas resistentes a herbicidas, contaminación de cuerpos de agua, pérdida de biodiversidad, aumento en las poblaciones de insectos plaga y afectación de la salud de trabajadores agrícolas debido al uso intensivo de herbicidas. Objetivo. Analizar el origen de las malezas en la agricultura, las características biológicas que las hacen perjudiciales para las actividades del hombre y sus funciones ecológicas en el agroecosistema, así como proponer la aplicación del concepto de biodiversidad funcional para el manejo agroecológico de la vegetación en campos agrícolas. Desarrollo. En este momento de cambio hacia una producción agrícola con un menor uso de plaguicidas, el manejo de las malezas sigue siendo un gran reto. Para lograr que el manejo integrado de malezas avance hacia estrategias agroecológicas que permitan una reducción del uso de herbicidas es necesario promover las interacciones bióticas benéficas que regulan de forma natural a las malezas. El estudio y aplicación de la biodiversidad funcional en los agroecosistemas surge entonces como una necesidad para manejar la vegetación de forma tal que se minimicen los efectos negativos de las malezas en los cultivos y se maximicen los servicios agroecosistémicos de las arvenses. Conclusión. La diferenciación entre malezas y arvenses como parte de un manejo agroecológico de los sistemas de cultivo permitiría mantener un balance positivo productividad-biodiversidad en los agroecosistemas.

“…In the 1950s, plastic mulches began to be used, due to their ability to increase the soil temperature [4]. Soil covers enhance total yields, control soil erosion, and suppress weed growth [1,[5][6][7][8]. In addition, mulches, by influencing the temperature and improving the physical structure of the soil, produce a microclimate that improves the productivity in the use of water and fertilizers [9] and modifies the energy balance of the soil [10].…”

The use of mulching in agriculture suppresses the weeds around crop plants, enhances the nutrients status of soil, controls the soil structure and temperature, and reduces soil water evaporation. Excessive use of low-density polyethylene mulches is contributing to the accumulation of high amounts of plastic wastes, an environmental problem for agricultural ecosystems. Fragments of plastic from such wastes can be found in soils, in water resources, and in organisms, including humans. The objective of this work was to study the economic viability of the use of different hydromulches in an artichoke crop. Three blends were prepared by mixing paper pulp (recycled from used paper) and cardboard (from paper mills) with different additives: wheat straw (WS), rice hulls (RH), and substrate used for mushroom cultivation (MS). These were compared with low-density polyethylene (Pe), a treatment without mulching on bare soil where hand weeding was performed (HW), and a treatment without mulching on bare soil where herbicide was applied (H). The results indicate that the use of hydromulch in an artichoke crop represents a good alternative for reducing plastic waste in agriculture. The net profits of the hydromulch treatments (MS, WS, RH) were higher than for HW and H, and slightly lower than for Pe. The most profitable treatment was Pe (€0.69 m−3), followed by RH (€0.59 m−3), WS (€0.58 m−3), MS (€0.47 m−3), HW (€0.36 m−3), and H (€0.32 m−3). A sensitivity analysis showed a probability of negative results of 0.04 in Pe, 0.13 in SM, 0.08 in WS, and 0.07 in RH, so the probability that the grower will make a profit is greater than 0.9 with the use of mulch (except mushroom substrate) or polyethylene.

Parapatric Genetic Lineages Persist in a Multiply Introduced Non-native Bush-Cricket

et al. 2022

To understand colonization success of an invasive species we need to know the origin of the founders, where and when they were introduced, and how they spread from the introduction site(s) through the landscape. Admixture of different genetic lineages from multiple introductions is generally hypothesized to be beneficial to invasive species thanks to adaptive variation and heterozygosity-fitness correlations. In this study, population genetic and landscape data was gathered for Roesel’s bush-cricket, Roeseliana roeselii a small bush-cricket common in central and eastern Europe that currently is expanding its range in northern Europe. We examined how colonization history and landscape structure affect the spread of the species and its population genetic structure, as a consequence of multiple introductions. Using comprehensive information of the species ecology and dispersal, together with genetic structure inferred from samples from 29 locations in central Sweden (we employed data published by Preuss et al., 2015), we found that two parapatric founding lineages have coexisted with very little gene flow during a long time span. An isolation-by-distance pattern and a decrease of genetic diversity toward marginal areas were more pronounced in the lineage situated in forest dominated landscapes. Our findings are in strong contrast to the hypothesis that different genetic lineages will admix when introduced to the same area. The presence of the separate lineages decades after introduction and without physical barriers for gene flow shows that some mechanism prevents them from admixture. One possibility is that the lineages with different genetic setups have adapted independently to local conditions and their admixture resulted in loss of locally adapted genotypes and hybrid offspring, less viable than the respective ancestral genotypes. However, an alternative post-mating reproductive barrier and hybrid breakdown phenomenon should also be considered. Our data indicate that besides landscape characteristics, human transportation of agricultural goods may play an important role for the overall spatial genetic pattern of the species in the study area by aiding the spread of the species.
