“…Functionally differences were observed for TNT and RDX in terms of representative species count (Figure 4) and CWM values, yet there were no significant impacts for Comp B plots. Similar response patterns have been observed at the individual scale for both morphological and physiological characteristics [70]. TNT appears to influence belowground structures and photosynthetic operation while RDX impacts aboveground structures as well as photosynthetic operation [70]- [72].…”

“…Similar response patterns have been observed at the individual scale for both morphological and physiological characteristics [70]. TNT appears to influence belowground structures and photosynthetic operation while RDX impacts aboveground structures as well as photosynthetic operation [70]- [72]. Unlike the two constituent compounds, Comp B tends to produce reduced impacts, requiring larger concentrations to induce the same level of impairment at the species level.…”

Natural selection processes are constantly influencing vegetation community composition. In the presence of anthropogenic contaminants additional forces act as filters controlling persistence of naturally occurring species. Classical species diversity and richness metrics can miss subtle changes under disturbance regimes while species composition and functional characteristics may be able to detect them. Our study was designed to investigate legacy impacts of explosives contaminated soils in an experimental minefield on vegetative communities using ecological metrics. As hypothesized, species diversity and richness showed no change in the presence of explosive compounds while species composition provided clear separation of groups and functional trait dominance was also observed to change. Overall, presence of anthropogenic contaminates have led to community composition and functional shifts for vegetation after initial contamination. The responses in species composition and functional diversity/richness were a result of new tolerant species filling open niches in contaminated plots. More work is needed to confirm this in varied systems and in the presence of diverse contaminants.

Energy demand of greenhouses is an important factor for their economics and photovoltaics can be considered an alternative solution to cover their electrical and heating needs. On the other hand, plants cultivated under different solar radiation intensities usually appear different physiological adaptations. The objective of this research was to investigate the effect of photovoltaic panels' induced partial shading on growth and physiological characteristics of lettuce (Lactuca sativa L.) and rocket (Eruca sativa Mill.) plants. Our results indicate that lettuce productivity and the corresponding photosynthetic rate were not affected under the photovoltaic cultivation in comparison with the reference one. On the other hand, the rocket cultivation was less productive and showed lower photosynthetic rate under photovoltaic panels than in the reference greenhouse. The different physiological response between lettuce and rocket seems to be associated with the effect of environmental factors such as solar radiation intensity, temperature and humidity apart from the possible inherent characteristics of each plant species.

“…Además, otras características de crecimiento (planta, longitud del tallo y raíz y longitud de la hoja, ancho y superficie), las cuales se incrementaron hasta un 13% mediante el sombreado, lo que coincide con estudios previos en diferentes cultivares de lechuga (Marrou et al, 2013;Tani et al, 2014). Se observó relaciones negativas entre la conductancia estomática y la fotosíntesis (Via et al, 2014) y la conductancia y transpiración (Bunce, 1996). Los estomas juegan un papel esencial en el intercambio de gases de las hojas, controlando tanto las pérdidas de agua como la absorción de CO 2 .…”

Objetivo. Evaluar agronómica y fisiológicamente el desarrollo de cultivares de lechuga en condiciones protegidas. Materiales y métodos. Bajo un diseño en bloques completamente al azar se evaluó el crecimiento, las características agronómicas y fisiológicas de cinco cultivares de lechuga en dos sistemas de agricultura protegida y en condiciones de campo abierto. Resultados. Los cultivares White Boston y Romana Parris Island Coss en casa malla y campo abierto tuvieron los mayores valores en variables fisiológicas (fotosíntesis cerca de 25.00 µmol CO2 m2 /s, transpiración mayor a 7.00 mmol agua m 2 /s y conductancia estomática mayor a 1.50 mmol agua m 2 /s), lo que provocó los mayores valores en biomasa fresca área y raíz (95.90 y 3.55 g, respectivamente). La variable fotosíntesis en plantas sembradas en campo abierto alcanzaron valores de 22.29 µmol CO2 m 2 /s, comparado con casa malla e invernadero con 17.14 y 14.16 µmol CO2 m 2 /s. Conclusiones. La capacidad de estos cultivares de lechuga a tolerar estrés por calor se debió a mecanismos morfológicos y fisiológicos, entre ellos, hoja de larga vida, control estomático y alto potencial fotosintético.
