“…However, the mechanism by which excessive N influences lichens is currently under debate. An indirect effect of atmospheric ammonia on tree bark pH (van Herk, 2001) has been suggested; an effect that can be confounded/or correlated with the influence of dust, especially relevant in Mediterranean areas (Branquinho et al, 2008;Loppi and Pirintsos, 2000). Nevertheless it remains inconclusive if the change in bark pH is merely a consequence of pollution to which lichens are directly responding (Spier et al, 2010).…”

“…However, unlike these previous works done in Mediterranean ecosystems, we monitored [NH 3 ] atm for a full year, allowing us to fully account for Mediterranean climate seasonality and variability in [NH 3 ] atm . Moreover, other environmental factors that could influence lichens, such as industrial pollutants or regional climate (Giordani and Incerti, 2008;Pinho et al, 2008a), dust (Loppi and Pirintsos, 2000;Pinho et al, 2008b) or land-use intensity (Pinho et al, 2008;Stofer et al, 2006) were constant throughout our study site. Thus we were able to provide more accurate estimates of CLEs and CLOs for semi-natural areas for the first time for European Mediterranean ecosystems.…”

“…The establishment of CLEs for ammonia has been mostly grounded on empirical work (Bobbink et al, 2011;Fenn et al, 2008), quantifying the effect of increasing [NH 3 ] atm on a receptor (Cape et al, 2009). In fact, due to lichens dependence on atmospheric nutrition, lichens respond directly to atmospheric pollution, making them ideal to establish thresholds of airborne N. Lichens have frequently been used to assess the effects of industrial pollution (Augusto et al, 2009;Branquinho et al, 2008;Giordani, 2007;Pinho et al, 2004) providing spatially explicit information on the effects of those pollutants (Pinho et al, 2008a, b). For both CLOs and CLEs, lichen communities have been used as one of the most sensitive receptors; recent proposal for revision of CLEs was mainly based on alterations in lichen communities (Cape et al, 2009;Fenn et al, 2008) and the most recent CLOs established for a large number of ecosystems were also based on lichens (Bobbink et al, 2011).…”

Abstract. Nitrogen (N) has emerged in recent years as a key factor associated with global changes, with impacts on biodiversity, ecosystems functioning and human health. In order to ameliorate the effects of excessive N, safety thresholds such as critical loads (deposition fluxes) and levels (concentrations) can be established. Few studies have assessed these thresholds for semi-natural Mediterranean ecosystems. Our objective was therefore to determine the critical loads of N deposition and long-term critical levels of atmospheric ammonia for semi-natural Mediterranean evergreen woodlands. We have considered changes in epiphytic lichen communities, one of the most sensitive comunity indicators of excessive N in the atmosphere. Based on a classification of lichen species according to their tolerance to N we grouped species into response functional groups, which we used as a tool to determine the critical loads and levels. This was done for a Mediterranean climate in evergreen cork-oak woodlands, based on the relation between lichen functional diversity and modelled N deposition for critical loads and measured annual atmospheric ammonia concentrations for critical levels, evaluated downwind from a reduced N source (a cattle barn). Modelling the highly significant relationship between lichen functional groups and annual atmospheric ammonia concentration showed the critical level to be below 1.9 µg m −3 , in agreement with recent studies for other ecosystems. Modelling the highly significant relationship between lichen functional groups and N deposition showed that the critical load was lower than 26 kg (N) ha −1 yr −1 , which is within the upper range established for other semi-natural ecosystems. Taking into account the high sensitivity of lichen communities to excessive N, these values should aid development of policies to protect Mediterranean woodlands from the initial effects of excessive N.

“…Humans are changing the availability of other micronutrients other than sodium, and it is likely that similar effects hold true for those micronutrients. For instance, given that calcium affects the abundance and development of birds, snails, and worms (72)(73)(74), anthropogenic changes in calcium (75,76) may be particularly relevant for these taxa. Our results highlight the need for more comprehensive descriptions of how nutrition is changing in the face of humans and the diverse responses across traits and species to such changes.…”

The development of organisms is changing drastically because of anthropogenic changes in once-limited nutrients. Although the importance of changing macronutrients, such as nitrogen and phosphorus, is well-established, it is less clear how anthropogenic changes in micronutrients will affect organismal development, potentially changing dynamics of selection. We use butterflies as a study system to test whether changes in sodium availability due to road salt runoff have significant effects on the development of sodium-limited traits, such as neural and muscle tissue. We first document how road salt runoff can elevate sodium concentrations in the tissue of some plant groups by 1.5-30 times. Using monarch butterflies reared on roadside-and prairie-collected milkweed, we then show that road salt runoff can result in increased muscle mass (in males) and neural investment (in females). Finally, we use an artificial diet manipulation in cabbage white butterflies to show that variation in sodium chloride per se positively affects male flight muscle and female brain size. Variation in sodium not only has different effects depending on sex, but also can have opposing effects on the same tissue: across both species, males increase investment in flight muscle with increasing sodium, whereas females show the opposite pattern. Taken together, our results show that anthropogenic changes in sodium availability can affect the development of traits in roadside-feeding herbivores. This research suggests that changing micronutrient availability could alter selection on foraging behavior for some roadside-developing invertebrates.nutritional ecology | Danaus plexippus | Pieris rapae | ecological stoichiometry

The aim of this research was to determine the concentrations of calcium, iron, manganese, zinc, potassium and sodium in the water and leaves of Aechmea blanchetiana (Baker) L.B species collected between the cities of Ilhéus and Itacaré, Bahia, Brazil and verify if the metals found in the water can be absorbed by the leaves. Flame atomic absorption spectrometry (F AAS) and flame photometry were used for the determination of metals. pH measurements, dissolved oxygen and water temperature were also made. The results obtained were used in an exploratory analysis. Principal component analysis (PCA) showed clearly the distinct formation of two clusters and the correlation analysis indicated that the leaves of A. blanchetiana seem to absorb iron, calcium, manganese and zinc from the water tank.Keywords: Bromeliaceae; Aechmea blanchetiana; metals; water and leaves. INTRODUÇÃOA Aechmea blanchetiana (Baker) L.B é uma espécie da família Bromeliaceae Juss., um importante táxon vegetal, com 58 gêneros e 3.172 espécies.1 O embricamento das folhas em forma de roseta, em muitas espécies, forma um reservatório (fitotelma) onde se acumula água e nutrientes, por isso essas bromélias são conhecidas como bromélias-tanque. Este microhabitat é utilizado como abrigo e para reprodução por diversos organismos, como algas, bactérias, anfíbios, rép-teis e insetos, sendo inclusive o único ambiente onde algumas espécies podem sobreviver.2 Esses organismos deixam restos de suas atividades metabólicas no reservatório, tornando-o um local rico em nutrientes e um importante microhabitat nos ecossistemas dos quais fazem parte.3 Na família Bromeliaceae a captação de nutrientes também ocorre pelos tricomas foliares, especialmente as bromélias epífitas, que utilizam essas estruturas como única forma de obtenção de água e nutrientes. 4 Estes tricomas acabam absorvendo também poluentes atmosféricos e, por isso, são muito úteis para o biomonitoramento de contaminação atmosférica. 5,6 Essa característica faz com que esses organismos sejam bastante utilizados como uma ferramenta efetiva e de baixo custo para a avaliação da deposição de elementos traço. 7,8 Zampieri et al. avaliaram a absorção e translocação de Ca, Co, Fe, K e Zn em Aechmea blanchetiana com plantas cultivadas in vitro em meios de cultivo contendo diferentes concentrações de Zn. A espécie apresentou tolerância a altos níveis do metal, possibilitando a utilização no biomonitoramento de áreas contaminadas por Zn. Giampaoli et al. estudaram o crescimento e desenvolvimento de Aechmea blanchetiana com plantas in vitro na presença de Cu e Zn. Acúmulo significante ocorreu para os dois elementos, caracterizando a espécie como capaz de bioacumular esses metais.10 Além de absorver água e nutrientes, alguns autores citam as bromélias como fontes de criadouros de Aedes aegypti. 11,12O uso de organismos vivos na caracterização ambiental tem sido cada vez mais frequente, uma vez que estes auxiliam no mapeamento espacial e temporal da poluição atmosférica e das oscilações naturais ocorridas nos ecossiste...
