Putting the elephant back in the herd: elephant relative quantity judgments match those of other species.
Abstract The ability to discriminate between quantities has been observed in many species. Typically, when an animal is given a choice between two sets of food, accurate performance (i.e., choosing the larger amount) decreases as the ratio between two quantities increases. A recent study reported that elephants did not exhibit ratio effects, suggesting that elephants may process quantitative information in a qualitatively different way from all other nonhuman species that have been tested (Irie-Sugimoto et al. in Anim Cogn 12:193-199, 2009). However, the results of this study were confounded by several methodologic...

The subspecies concept in butterflies: has its application in taxonomy and conservation biology outlived its usefulness?
Subspecies lie at the interface between systematics and population genetics, and represent a unit of biological organization in zoology that is widely used in the disciplines of taxonomy and conservation biology. In this review, we explore the utility of subspecies in relation to their application in systematics and biodiversity conservation, and briefly summarize species concepts and criteria for their diagnosis, particularly from an invertebrate perspective. The subspecies concept was originally conceived as a formal means of documenting geographical variation within species based on morphological characters; however, th...

Capuchin monkeys (Cebus apella) let lesser rewards pass them by to get better rewards.
This study introduced a new task that could be used comparatively to measure self-control in an intuitive context that involved responses that required no explicit training. Capuchin monkeys (Cebus apella) were given a choice between two food items that were presented on a mechanized, revolving tray that moved those foods sequentially toward the monkeys. A monkey could grab the first item or wait for the second, but was only allowed one item. Most monkeys in the study waited for a more highly preferred food item or a larger amount of the same food item when those came later, and they inhibited the prepotent response to gra...

As it stands, House of Lords reform would probably do away with most of the scientists and doctors in the upper chamberWe live in a society that is, to a large extent, created by science and technology. Without them, we'd have no modern healthcare, communications, transport or agriculture. Music, art, literature and film all rely on technology for their transmission. And yet our political system generally fails to recognise the impact of science.

Toral lateral line units of goldfish, Carassius auratus, are sensitive to the position and vibration direction of a vibrating sphere
Abstract We recorded the responses of lateral line units in the midbrain torus semicircularis of goldfish, Carassius auratus, to a 50-Hz vibrating sphere and determined the unit’s spatial receptive fields for various distances between fish and sphere and for different directions of sphere vibration. All but one unit responded to the vibrating sphere with an increase in discharge rate. Only a proportion (25 %) of the units exhibited phase-locked responses. Receptive fields were narrow or broad and contained one, two or more areas of increased discharge rate. The data show that the receptive fields of to...

Molecular diversity, metabolic transformation, and evolution of carotenoid feather pigments in cotingas (Aves: Cotingidae)
Abstract Carotenoid pigments were extracted from 29 feather patches from 25 species of cotingas (Cotingidae) representing all lineages of the family with carotenoid plumage coloration. Using high-performance liquid chromatography (HPLC), mass spectrometry, chemical analysis, and 1H-NMR, 16 different carotenoid molecules were documented in the plumages of the cotinga family. These included common dietary xanthophylls (lutein and zeaxanthin), canary xanthophylls A and B, four well known and broadly distributed avian ketocarotenoids (canthaxanthin, astaxanthin, α-doradexanthin, and adonixanthin), rhodoxanthin,...

Commensal bacteria coated by secretory immunoglobulin A and immunoglobulin G in the gastrointestinal tract of pigs and calves
In this study, we evaluated the distribution of S‐IgA‐coated commensal intestinal bacteria in each portion of the gastrointestinal tracts of pigs and calves. Immunoglobulin G (IgG)‐coated bacteria were also analyzed because a considerable amount of IgG is secreted in the gastrointestinal tracts of pigs, and in particular, calves. S‐IgA‐ or IgG‐coated bacteria were detected in all the segments of the gastrointestinal tracts of pigs and calves. The proportion of S‐IgA‐coated bacteria to total bacteria (i.e. S‐IgA coating ratio) varied in the segments of the gastrointestinal tract in pigs, whereas those of c...

Objectives and applications of phenotyping network set‐up for livestock
ABSTRACTProviding phenotypic information, which is accurate, reliable, repeatable and comparable across countries or laboratories, is critical to gain a better understanding of the relationship between genes and phenotypes. So far, it is indeed extremely difficult to combine different sources of phenotypic data from multiple origins, partly because of the variability in the methods of phenotyping. The phenotyping program of livestock involves the definition of complex phenotypes obtained from data integration at different levels (from molecules to herds), the implementation of the latest technologies to accurately characte...

The involvement of N‐glycosylation of zona glycoproteins during meiotic maturation in sperm–zona pellucida interactions of porcine denuded oocytes
ABSTRACTThe present study was conducted to delineate whether N‐glycosylation of zona pellucida (ZP) glycoproteins occurred during meiotic maturation and whether this N‐glycosylation played a role in sperm–ZP interactions of porcine cumulus denuded oocytes (DOs). After mechanical removal of cumulus cells from cumulus oocyte complexes (COCs), DOs were cultured for 44 h in in vitro maturation (IVM) culture. The experiments were carried out to determine the effects of tunicamycin, a specific N‐glycosylation inhibitor, for various intervals during IVM on sperm–ZP interactions in porcine DOs. The results determined t...

ABSTRACTWe assessed fumonisin production during the ensiling of rice grain. Rice grain was harvested at the full‐ripe stage and prepared as rough rice, crushed rough rice, brown rice or crushed brown rice. Each material was ensiled under six conditions: (1) no fungus, anaerobic; (2) no fungus, aerobic; (3) water added, anaerobic; (4) water and fumonisin‐producing fungus added, anaerobic; (5) water and fumonisin‐producing fungus added, aerobic; or (6) fumonisin‐producing fungus added to autoclaved material, aerobic. After 40 days of ensilage, we analyzed the silage fermentative quality and fumonisin concentration....

Distribution of protein disulfide isomerase during maturation of pig oocytes
In this study, we investigated the time course and illustrated the possible functional role of ER distribution during maturation of porcine oocytes by immunostaining with protein disulfide isomerase (PDI). PDI forms clusters in the cytoplasm of oocytes. After immunostaining, PDI clusters were identified throughout the cytoplasm from the GV to metaphase I (MI) stage; however, at the MII stage, the PDI formed large clusters (1–2 µm) in the animal pole around the first polar body. PDI distribution was prevented by bacitracin, a PDI inhibitor. Our experiments indicated that, during porcine oocyte maturation, PDI undergoes...

Patterns of functional enzyme activity in fungus farming ambrosia beetles
Conclusion: Similar to closely related fungi associated with bark beetles in phloem, the microbial symbionts of ambrosia beetles do not degrade cellulose. Instead, their enzyme activity is directed mainly towards comparatively more easily accessible hemicellulose components of the ray-parenchyma cells in the wood xylem. Furthermore, the detection of xylanolytic enzymes exclusively in larvae and not in adults indicates that larvae (pre-) digest plant cell wall structures exclusively in larvae (which feed on fungus colonized wood) and not in adults (which feed only on fungi). This implies that in X. saxesenii and likely also...

Fish immune responses against endoparasitic nematodes – experimental models
AbstractVertebrates mount a series of immune reactions when invaded by helminths but antihelmintic immune strategies allow, in many cases, the first invaders of the non‐immune host to survive for prolonged periods, whereas subsequent larval invaders of the same parasite species face increased host resistance and thereby decreased colonization success. This concomitant immunity may represent a trade‐off between adverse side effects (associated with killing of large helminths in the host tissue) and the need for future protection against invasion. Encapsulation and isolation of large live endoparasitic larvae may be asso...

Peracetic acid is effective for controlling fungus on channel catfish eggs
This study determined the effectiveness of PAA for fungus control on channel catfish, Ictalurus punctatus (Rafinesque), eggs. The study consisted of five PAA concentrations (2.5, 5, 10, 15 and 20 mg L−1) and an untreated control in a flow‐through system. A single spawn was used for each replication (N = 4). Eggs were treated twice daily until the embryos developed eyes. When hatching was complete for all viable eggs, fry were counted to determine the percent survival in each treatment. Fungal growth was severe in the untreated controls resulting in 11% survival. Treatments of 2.5, 5 and 10 mg L−1 PAA were...
