“…In order to study the gut content, we introduced each specimen in a vial with Hertwigs' liquid and heated them in an oven at 65°C for 20-24 h, following the methodology of Bello and Cabrera (1999) used in other studies of larval feeding (e.g., Derka et al, 2004;Tierno de Figueroa et al, 2006;Fenoglio et al, 2007). By using a microscope with an ocular micrometer, we estimated the percentage of the absolute gut content (at 409) as the total area occupied by the content in the whole digestive tract, and the relative gut content (at 4009) as the area occupied for each component within the total gut content.…”

Life history and larval feeding of some species of Ephemeroptera and Plecoptera (Insecta) in the Sierra Nevada (Southern Iberian Peninsula)

We monitored two high mountain streams from the Sierra Nevada (Southern Spain) monthly throughout an annual cycle, measuring and analyzing physical and chemical parameters. Temperature was hourly registered. We studied life cycles and larval feeding of four mayfly species [Serratella ignita (Poda, 1761), Serratella spinosa nevadensis (AlbaTercedor, 1981), Alainites muticus (Linnaeus, 1758), and Baetis alpinus Pictet, 1843] and two stonefly species [Amphinemura triangularis (Ris, 1902) and Capnioneura mitis Despax, 1932]. Some species changed their strategies (growth rate, life cycle duration, and/or voltinism) in accordance with different conditions (depending on the altitude and temperature). The gut content data showed that species fed mainly on detritus (as collector-gatherers or as shredders), except B. alpinus that behaved as a scraper in one of the streams. Differences in the larval diet of the same species in different streams, and even through its life, support the idea of not using general models to extrapolate the function of a species from a higher taxonomical level.

“…Ten individuals per species and habitat were used in the present study (for further details on distribution and characteristics of habitats see Vázquez-Luis et al, 2008). Therefore, the gut contents of a total of 240 specimens of 14 amphipod species were examined following the methodology proposed by Bello & Cabrera (1999) with slight variations (Tierno de Figueroa et al, 2006;Guerra-García & Tierno de Figueroa, 2009). Each individual was added to a vial with Hertwig's liquid (consisting of 270 g of chloral hydrate, 19 ml of chloridric acid 1 N, 150 ml of distilled water and 60 ml of glycerin) and heated in an oven at 658C for 3 to 6 hours, depending on the cuticle thickness of the specimens.…”

Does the invasion ofCaulerpa racemosavar.cylindraceaaffect the feeding habits of amphipods (Crustacea: Amphipoda)?

Ecological interactions involving introduced seaweeds constitute an important research gap, since they could alter the trophic dynamics of native populations, but indirect effects on trophic levels are poorly known. The seaweedCaulerpa racemosais one of the most notable invaders in the Mediterranean Sea. It is well known thatC. racemosamodifies the amphipod community with respect to native habitats, but nothing is known regarding the common use of the same trophic resources. Therefore, the aim of this study was to assess if the feeding habits of amphipods associated with algal habitats are affected by the spread of the invasiveC. racemosa, through stomach content analysis of amphipods living in both native and invaded seaweed assemblages. A total of 240 specimens of 14 species of amphipods were examined. Ten species were present in both studied habitats (native and invaded), while two were exclusive to native and invaded habitats, respectively. Ten individuals of each species at each habitat were selected and their gut contents were examined. A total of 11 different items was found in the gut contents: detritus; vegetal detritus; algae; animal tissue; Oligochaeta; Polychaeta; Foraminifera; Crustacea; Sipuncula; diatoms; and non-identified items. The expansion ofC. racemosainto the native algal community changes the feeding habits of herbivorous amphipods, since their preferred food (epiphytic algae) is not available in the new habitat produced byC. racemosa. This community change occurs because of the presence of caulerpenyne inC. racemosa, which retards the growth of epiphytic algae. Nevertheless, other species are not affected or benefited by the invasion, such as detritivorous species whose main food source and habitat remains available. Altogether, slight changes in the trophodynamism of amphipod assemblages have been detected, which are not seen as relevant in an initial stage. However, they might be promoting some indirect effects in the energetic budget of populations, which may affect the life history. Further studies on food-web interactions in the ecosystems affected by invasive species are necessary.

“…The gut examination methodology used in this study has been applied previously by entomologists (Tierno de Figueroa et al 2006) and was successfully used for amphipods (Navarro-Barranco et al 2013;Vazquez-Luis et al 2013;Guerra-García et al 2014). Gut content analyses are an accurate direct indicator, which is an advantage compared with indirect indicators, such as stable isotope and fatty acid analyses.…”
