Analysis of organic acids has become increasingly important due to their role in the physiological activity of plants, and many separation methods have been developed for the simultaneous determination of these compounds in plant samples. Herein, ultra fast liquid chromatography and photodiode array detection (UFLC-PDA) was applied to the analysis of organic acids in young shoots, leaves, aerial parts and flowering shoots, as well as in flowers and fruits, of thirty five plant species, according to their traditional use. The studied plants were divided in three groups: traditionally cultivated food plants, wild edible plants and wild medicinal plants. Most of the species were characterized for the first time. Among all the analysed species, Rumex acetosella leaves and aerial parts revealed the highest content of total organic acids. Overall, the organic acids found in the studied plant species make them suitable to be used as food additives such as antioxidants (e.g. ascorbic acid) or acidulants (e.g. citric and malic acids).

The incidence of Listeria monocytogenes in three cheese manufacturing plants from the northeastern region of Sao Paulo, Brazil, was evaluated from October 2008 to September 2009. L. monocytogenes was found in samples from two plants, at percentages of 13.3% (n = 128) and 9.6% (n = 114). Samples of raw and pasteurized milk, water, and Minas Frescal cheese were negative for L. monocyto genes, although the pathogen was isolated from the surface of Prato cheese and in brine from one of the plants evaluated. L. monocytogenes was also isolated from different sites of the facilities, mainly in non food contact surfaces such as drains, floors, and platforms. Serotype 4b was the most predominant in the plants studied. The results of this study indicate the need for control strategies to prevent the dispersion of L. monocytogenes in the environment of cheese manufacturing plants.; Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)

Nas ultimas décadas, a elevação do consumo e do custo dos fertilizantes minerais tem preocupado o setor agrícola mundial. Portanto, o uso do lodo de esgoto tratado (biossólido) como adubo está sendo incentivado em diversos países, visto que aumenta a produtividade e gera benefícios pela reciclagem da matéria orgânica e nutrientes contidos em sua composição. Ainda assim, a presença de elementos potencialmente tóxicos (ex. metais pesados) no lodo e a falta de conhecimento sobre o seu efeito residual no ambiente, principalmente, em casos onde há a alteração do uso agrícola do solo, têm contribuído para a sua disposição final em aterros sanitários. Esta pesquisa pressupõe que o uso agrícola do lodo de esgoto, mesmo algum tempo após a sua aplicação ao solo, continua exercendo efeito residual favorável sobre a produtividade (biomassa) e a ciclagem de nutrientes em plantios de eucalipto, bem como em culturas de plantas alimentícias. No município de Itatinga-SP, foram instalados três experimentos com povoamentos de Eucalyptus grandis, sendo: (1) Prática de desbaste em dois talhões de eucalipto plantados em 1998, sobre Latossolo Vermelho-Amarelo (LVA) e Latossolo Vermelho Escuro (LVE), e adubados com 20 t ha-1 lodo de esgoto; (2) Prática da talhadia (condução de rebrota) em parcelas cultivadas com eucalipto e adubadas (em 2003) com 10...

The objective of this study was to conduct an inventory of food plants cultivated and collected from the native and ruderal vegetation in the Atlantic Forest region by the rural population residing in the Santa Virginia Nucleus of the Serra do Mar State Park (Puruba and Guaricanga neighborhoods) and surroundings (Vargem Grande neighborhood). The 23 interviewees were sampled to meet the following criteria: originating from the rural area of the municipalities where the Nucleus is located; more than 45 years old; close familiarity with working the land. A total of 146 botanical species were identified, distributed among 43 botanical families, with the families Solanaceae and Cucurbitaceae being the most represented and basically horticultural. The Shannon-Wiener diversity index and Pielou evenness were 1.90 (base 10) and 0.95, respectively, for the group residing in the Nucleus and 1.97 and 0.92 for the population located in the area surrounding the Nucleus. The two groups of neighborhoods presented similarity regarding the food plants cited (75%), and about 17% of the plants cited are native to the Atlantic Forest. We found significant richness and variety of species cultivated in the yards and fields which serve to complement the diet...

Phytophagous hemipterans (heteropterans) are, in general, polyphagous, feeding on a wide array of plants. Among these, less preferred plant food sources are also explored as food and/or shelter. To illustrate this, I will discuss the feeding behavior of the southern green stink bug, Nezara viridula (L.) (Pentatomidae) on less preferred plants in Northern Paraná state. This bug feeds on several uncultivated-wild, and on cultivated plants, which are less preferred, changing its feeding behavior, from a typical seed/fruit sucking habit, to leaf/stem feeding, with consequences for its nymphal and adult performance. Other seed suckers, such as Euschistus heros (F.) and Dichelops melacanthus (Dallas) (Pentatomidae) and Neomegalotomus parvus Westwood (Alydidae), also change their feeding behavior from seeds to vegetative tissues (leaf, stems) when feeding on less preferred food plants. These and other mentioned examples demonstrate that for this feeding guild in particular, the less preferred food plant sources play an important role in the life history of these bugs, and that this fact is, in general, underestimated.

To determine the feeding habits of the Amazonian manatee Trichechus inunguis in some Central Amazonian rivers and lakes, we compared plant epidermis found in the stomach contents and/or faeces of animals with a reference collection of plants present in the studied areas. Twenty five samples from digestive tracts of animals found dead and 25 faeces samples found floating were analyzed. From these samples, 24 aquatic macrophytes were identified. The Gramineae family was identified in 96% of the samples, Paspalum repens and Echinochloa polystachya being the most abundant in the samples. The second most frequent family was the Pontederiaceae primarily Eichhornia crassipes. During the high water period, the animals showed a more selective diet (eight identified species). In the low water period, when food was more scarce, the animals showed a larger diversity of species in their diet (21 species of plants). Differences in the diet among the two studied areas reflected the physiographics characteristics of the region. Amazonian manatees fed mostly on emergent plants.

Several recent studies suggest that the level of generalization (measured as percentage connectance) of plant-pollinator networks has several ecological correlates, e.g. latitude and altitude. Here we report on levels of generalization in 27 two-mode networks of social bees and their food plants in various Brazilian habitats and urban environments. Social bees are generalist foragers and are among the most abundant flower visitors in Brazil. They probably account for 30-50% of all plant - flower visitor interactions. Connectance was significantly influenced by habitat. Cerrado forests showed lower connectance than the dry dune habitats, with Atlantic rain forest and urban sites taking intermediate position and arid Caatinga being similar to dunes. This shows that generalization in a plant - flower visitor community can be influenced by habitat even within a group of generalist flower visitors, in our case social bees. We show that the strength of the interactions is not different between Cerrado and semi-arid habitats (dunes and Caatinga) and discuss other explanations for our findings.

Plants have served as sources of food and medicines for human beings since their advent. During famines or conditions of food scarcity, people throughout the world depend on unconventional plant items to satiate their hunger and meet their nutritional needs. Malnourished people often suffer from various diseases, much more than people eating a balanced diet. We are hypothesizing that the unconventional food plants that people eat during times of scarcity of their normal diet are also medicinal plants and thus can play a role in satiating hunger, meeting nutritional needs, and serving therapeutic purposes. Towards testing our hypothesis, surveys were carried out among the low income people of four villages in Lalmonirhat and Nilphamari districts of Bangladesh. People and particularly the low income people of these two districts suffer each year from a seasonal famine known as Monga. Over 200 informants from 167 households in the villages were interviewed with the help of a semistructured questionnaire and the guided field-walk method. The informants mentioned a total of 34 plant species that they consumed during Monga. Published literature shows that all the species consumed had ethnomedicinal uses. It is concluded that famine food plants also serve as ethnomedicinal plants.

Previous studies of desert tortoise foraging ecology in the western Mojave Desert suggest that these animals are selective herbivores, which alter their diet according to the temporal availability of preferred food plants. These studies, however, did not estimate availability of potential food plants by taking into account the spatial and temporal variability in ephemeral plant abundance that occurs within the spring season. In this study, we observed 18 free-ranging adult tortoises take 35,388 bites during the spring foraging season. We also estimated the relative abundance of potential food plants by stratifying our sampling across different phenological periods of the 3-month long spring season and by different habitats and microhabitats. This methodology allowed us to conduct statistical tests comparing tortoise diet against plant abundance. Our results show that tortoises choose food plants non-randomly throughout the foraging season, a finding that corroborates the hypothesis that desert tortoises rely on key plants during different phenological periods of spring. Moreover, tortoises only consumed plants in a succulent state until the last few weeks of spring, at which time most annuals and herbaceous perennials had dried and most tortoises had ceased foraging. Many species of food plants—including several frequently eaten species—were not detected in our plant surveys...

Plant recovery rates after herbivory are thought to be a key factor driving recursion by herbivores to sites and plants to optimise resource-use but have not been investigated as an explanation for recursion in large herbivores. We investigated the relationship between plant recovery and recursion by elephants (Elephas maximus borneensis) in the Lower Kinabatangan Wildlife Sanctuary, Sabah. We identified 182 recently eaten food plants, from 30 species, along 14 × 50 m transects and measured their recovery growth each month over nine months or until they were re-browsed by elephants. The monthly growth in leaf and branch or shoot length for each plant was used to calculate the time required (months) for each species to recover to its pre-eaten length. Elephant returned to all but two transects with 10 eaten plants, a further 26 plants died leaving 146 plants that could be re-eaten. Recursion occurred to 58% of all plants and 12 of the 30 species. Seventy-seven percent of the re-eaten plants were grasses. Recovery times to all plants varied from two to twenty months depending on the species. Recursion to all grasses coincided with plant recovery whereas recursion to most browsed plants occurred four to twelve months before they had recovered to their previous length. The small sample size of many browsed plants that received recursion and uneven plant species distribution across transects limits our ability to generalise for most browsed species but a prominent pattern in plant-scale recursion did emerge. Plant recovery time was a good predictor of time to recursion but varied as a function of growth form (grass...

Survival and growth of larvae of the velvetbean caterpillar (VBC), Anticarsia gemmatalis Hiũbner, in the laboratory on four early season weedy legume species, three of which have not been reported previously as food plants, indicated that these could serve as larval food plants in the field. Larval development on white sweetclover, Melilotus alba Desrousseaux, black medic, Medicago lupulina L., and a vetch, Vicia angustifolia L., was similar to that on cultivated soybean, Glycine max (L.) Merrill, except that survival on V. angustifolia was very low. Compared with the other species, significantly greater weight gain and growth rate occurred on white clover, Trifolium repens L., associated with a significantly higher efficiency of conversion of ingested food to biomass (ECI), which was the product of a high approximate digestibility (AD) and a high efficiency of conversion of digested food to biomass (ECD). Approximately 50% greater food consumption on G. max and Medicago lupulina was associated with similarly low ECI values, which resulted from a low AD (G. max) or a low ECD (Medicago lupulina). Nitrogen content of G. max foliage was significantly less...

This study was carried out in the four rural communities (Pedrinhas, Ladeira, Caroba and Cajueiro) surrounding the National Park of Serra de Itabaiana - PARNASI, in order to assess which botanical species are recognized by local specialists as wild food plants. The methodology was based on stages of observation, questionnaires, performance-guided tours, and a floristic inventory. There were 31 specialties divided into three categories of emic wild food plants, those being for human consumption, for domestic animals and for wildlife animals as food. We totaled 86 species, 67% being native and 33% exotic. They were made up of the following families: Myrtaceae (16 spp.), Anacardiaceae (8 spp.), Arecaceae (8 spp.), Fabaceae (7 spp.), Annonaceae (5 spp.), and Malpighiaceae (5 spp.). 59 wild food species were identified for human use. The most cited were: cashew (Anacardium ocidentale L.), murici (Byrsonima sericea DC.), and jackfruit (Artocarpus heterophyllus Lam.). In the category of species for domestic animals, 22 species were cited, those being jackfruit (A. heterophyllus), ingá (Inga sp.), and mimosa (Mimosa sp.). In the category for wildlife animals, 26 species were cited, including angelim (Andira nitida Mart. ex Benth.), murici (B. sericea) and embaúba (Cecropia pachystachya Trécul). It was observed that specialists from the surrounding communities to PARNASI have a vast knowledge of wild food plant resources used for different purposes. As far as human consumption was concerned...

We used classical culture techniques to explore gut bacteria and changes associated with dietary change in the highly polyphagous, tropical caterpillar Automeris zugana (Saturniidae). Fifty-five third instar wild-caught sibs feeding on Annona purpurea (Annonaceae) in the Área de Conservación Guanacaste (ACG) in northwestern Costa Rica were divided into eight groups. Each of seven groups was reared to the ultimate instar on another species of food plant normally used by A. zugana. Some pupae were also analyzed for the presence of bacteria. Aerobic bacterial cultures were obtained from all 33 caterpillar guts and the eight pupae inventoried. There was no clear pattern in species composition of cultivated bacteria among the eight diets, and each caterpillar on a given food plant carried only a small fraction of the total set of species isolated from the set of caterpillars feeding on that food plant. Taken as a whole, the larvae and pupae contained 22 species of cultivable bacteria in 12 genera. Enterobacter, present in 81.8% of the samples, was the genus most frequently isolated from the caterpillars, followed by Micrococcus and Bacillus. Bacillus thuringiensis was isolated from 30.3% of the dissected caterpillars, but found in caterpillars feeding on only half of the species of food plants

The volume of secretion obtained from adult Zonocerus variegatus (Orthoptera: Pyrgomorphidae)was influenced by the type of food plants. Insects fed on leaves of cassava Manihot esculenta, bitter leaves Vernonia amygdalina, and a mixture of M. esculenta and Acalypha wilkesiana gave a good volume of secretion while Chromolaena odorata, Elaeis guinensis, Aspilia africana and Citrus sinensis did not favour secretion production. No significant difference was recorded in the volume of secretion obtained from Z. variegatus from the two seasons irrespective of the food plant. Similarly, food plants gave no significant difference on the volume of secretion between the two seasons.
