On June 22 nd , the alga was in the early stages of growth, while on August 31 st , it was fully grown.
Sites L1, L2 and L3 showed D. As stated previously, downstream of the Lumbreras discharge, the massive growth disappeared due to higher phosphate levels, according to our previous studies [ 10 ] carried out in the Lumbreras River , although isolated mats of filaments were found at sites L4 and L5 on August 31 st Fig 2. Consequently, the varying amounts of filaments of D. Water was collected, filtered and kept frozen until the levels of Soluble Reactive Phosphorus SRP could be analysed in the laboratory following the acidic molybdate method [ 31 ] using a spectrophotometer Shimadzu UV At each site and on both dates, an area of 3—5 streambed cobbles larger than 10 cm and continuously covered by flowing water were brushed with a toothbrush 75 cm 2 of each cobble to collect diatoms into a ml plastic jar, thus producing a single, pooled sample.
Cobbles were randomly chosen at each site, and the area was measured with a plastic sample sheet. In order to determine the biomass of the D. The identification of macroinvertebrates was generally made to genus level, except for some Diptera subfamilies and Oligochaeta.
Where necessary, sub-sampling was done in the sorting process, and at least individuals per sample were counted. For the macroinvertebrate assemblage, four biological traits locomotion, substrate preferences, feeding habits and food were considered, containing 35 categories obtained from Tachet et al. The traits in this database have an affinity score assigned for each taxa ranging from 0 to 5, from null affinity to high affinity, respectively [ 45 ].
The functional structure was calculated mostly based on genus level, always in line with the dataset requirements established by Tachet et al. Exponential regressions between D.

The DISTLM routine was based on the forward selection procedure and the AIC selection criteria [ 47 ], to obtain the environmental variables that accounted for further variation. Every studied site showed on both sampling dates high dissolved oxygen concentration values ranging from 8. The only physicochemical variable which showed noticeable differences among sites was SRP, especially after Lumbreras sewage discharge, increasing from 0. IHF index increased from 53 to 72 along the longitudinal profile of Lumbreras River.
The relative abundance of D. The taxonomic composition of the diatom assemblage, excluding D. Diatom species were grouped by genus in order to achieve more consistent results in the regression analysis of the D. Vaucheriae Kützing Lange-Bertalot, F. Lange-Bertalot, F. Among them, 5 taxa had a significant relationship with the biomass of D. Achnanthidium spp. The relative abundance of Cocconeis placentula and Gomphonema spp. Diatom assemblage diversity, measured using the Shannon diversity index, was also negatively related to the D.
Lower right Exponential regressions between D. Diatom assemblages located downstream of the Lumbreras sewage discharge sites L4, L5, L6 and L7 yielded similar results in both June and August, while the upstream diatom assemblages of sites L1, L2 and L3, all of which were affected by the massive growth, differ between dates due to the increase in D. Conversely, the ribbon forming Fragilaria capucina and several species of Gomphonema stand out by its contrary position to D.
Distance-based redundancy analysis dbRDA plot resulted from the DISTLM analysis that considered the diatom assemblage species level and the environmental variables at each site studied. The four groups of sites are represented by different symbols according to the sampling data and the site location along the longitudinal profile of the river.
Diatom species with a Spearman correlation coefficient of higher than 0. Regarding the functional structure of the diatom assemblage, four of the eight biological traits studied were shown to have a significant relationship to the biomass of the D. The relationship was positive for pioneer diatoms, while a higher biomass of filamentous mats was associated with a decrease in diatom size, and lower relative abundance levels of attached and colonial diatoms.
Regarding the taxonomic composition of the macroinvertebrate assemblage, 56 taxa were identified, generally to genus or sub-family level in Diptera. To achieve more consistent results in the regression analysis, different taxa were grouped to family level or higher, resulting in the identification of 39 taxa. The assemblage was clearly dominated by Baetidae Siphlonurus sp. The five which were discovered to have a significant relationship with the D.
Chironomidae, Oligochaeta and Hydra showed positive correlations; their density clearly increased in sites affected by the massive growth Fig 6. In contrast, Heptageniidae and Simuliidae negatively correlated with D. Finally, the relationship between D. Macroinvertebrate assemblage showed an important variability among sites and dates, according to the DISTLM analysis mostly based on genus or subfamilies densities Fig 7.
Accordingly, the sites were grouped on the dbRDA graph in line with how severe the D. Distance-based redundancy analysis dbRDA plot resulted from the DISTLM analysis, considering the macroinvertebrate assemblages mostly genus or subfamily level and the environmental variables studied at each site. The four groups of sites are represented using different symbols, according to the sampling data and the site location along the longitudinal profile of the river.
Regarding the functional structure of the macroinvertebrate assemblage mostly based on genus or subfamily level , and analyzed on the base of biological traits, 13 categories demonstrated a significant correlation with D. A higher density of filaments in the river substrate was associated with a decrease in the percentage of crawlers, shredders, scrapers and taxa adapted to live in the coarse substrate, as boulders, cobbles and pebbles Fig 8.
The number of predators and taxa adapted to live on macrophytes correlated positively with an increase in D. The main environmental variable related to macroinvertebrate and diatom assemblages variation among sites resulted D. Development of D. The remaining studied variables did not play an important role for river community alteration, since every studied sites showed similar and high dissolved oxygen concentration, low temperature and conductivity and slightly alkaline waters, according to other rivers affected by D.
Bhatt et al. Massive D. The increase in D. The increased biomass of the D. This finding is in accordance with our first hypothesis. Among these taxa, and taking into account the physical structure of the filamentous mats, those of greater size were especially affected, as has been seen in other studies [ 16 , 49 ]. Thus, in river sections with massive D. Diagram of the trophic interactions related to increased D. Circumference size represents the density of each kind of organism. The arrows represent the intensity of trophic interactions, increasing from the thinner dotted arrow to the thicker continuous one.
The main organisms included in each category are: Small diatoms A. Other taxa significantly affected by a high biomass of filaments, as we hypothesized, are those that live fixed to the substrate, such as Simuliidae, as there is a significant reduction in the area of substrate surface where they can fix themselves [ 22 , 50 ].
In spite of this, the newly formed filamentous framework favors smaller opportunistic taxa that are capable of adapting to the new environmental conditions such as Chironomidae and Oligochaeta, which also benefit from less competition for food, a consequence of the general decrease in the numbers of the organisms mentioned previously, and are further favored by the increase in the amount of FPOM Fine Particulate Organic Matter accumulated between the filaments due to reduced water velocity.
Aside from chironomids and Oligochaeta, the new environmental conditions created by D. Moreover, their small size compared to other predators [ 44 ] allows Hydra to better adapt to filamentous environments, and they benefits further from the increase in oligochaete and chironomid numbers, upon which they prey. Nevertheless, Hydra are not as efficient in the control of their populations as large predators are. The large predator Perlidae, a common family in the Lumbreras River, was completely absent at site L1, where the filamentous mats reached the highest densities.
El deseo de Dios es que podamos disfrutar la misma vida de victoria. Por tanto, nosotros todos A menudo nosotros queremos hacer todo y ganar todas las batallas para Dios de una vez. De igual modo, Dios sabia cuales batallas pelear y cuando pelearlas. Estas no eran solamente ciudades cananeas en la región, sino que eran fuertes militares.
Dios sabía lo que estaba haciendo al seleccionar batallas en particular para pelear, y cuando era necesario pelearlas. Esto también es verdad mientras peleamos contra nuestros enemigos espirituales. Podemos ganar solamente mientras vemos al Señor peleando por nosotros.
Él provee la victoria y nosotros caminamos en ella. Llegamos a darnos cuenta de que la victoria fue ganada en la cruz, y ahora necesitamos vivir a la luz de esa victoria. Romanos Decepcionarse de sí mismo es confiar en sí mismo. Eso muestra que hemos intentado pelear la batalla con nuestros recursos, y no en la victoria del Señor.
Este era un lugar de fe total. Compromiso y comunión con Dios, y el lugar donde Israel fue conquistado por Dios.
