Human–Nature Relationship in Mediterranean Streams: Integrating Different Types of Knowledge to Improve Water Management Ecology and Society
Clemente, Adelaide; Environmental Biology Centre, Faculty of Sciences, University of Lisbon; maclemente@fc.ul.pt; Nielsen, Kurt Aagaard; Department of Environmental, Social and Spatial Change, University of Roskilde; aagaard@ruc.dk; Branquinho, Cristina; Environmental Biology Centre, Faculty of Sciences, University of Lisbon; cmbranquinho@fc.ul.pt.
The social and ecological systems of Mediterranean streams are intrinsically linked as a result of long human occupation. In this region, these links vary greatly across small distances due to geomorphology, resulting in great diversity across space, which poses particular challenges for understanding and managing these systems. This demands (i) interdisciplinary integration of knowledge that focuses on the social–ecological interactions, while according due consideration to the whole; and also (ii) transdisciplinary integration, integrating lay and expert knowledge to understand local specificities. To address these needs—a focus on interactions and local knowledge—the research presented here studies the...

Oil gland and oil pores in billfishes: in search of a function ArchiMer
Dhellemmes, F.; Hansen, M. J.; Bouet, S. D.; Videler, J. J.; Domenici, P.; Steffensen, J. F.; Hildebrandt, T.; Fritsch, G.; Bach, Pascal; Sabarros, Philippe; Krüger, A.; Kurvers, R. H. J. M.; Krause, J..
Billfishes are well known for their distinctive elongated rostra, i.e. bills. The functional significance of billfish rostra has been frequently discussed and the recent discovery of an oil gland (glandula oleofera) at the base of the rostrum in swordfish, Xiphias gladius, has added an interesting facet to this discussion regarding the potential co-evolution of gland and rostra. Here, we investigated the oil gland and oil pores (through which the oil is brought to the skin surface) of four billfish species – swordfish, Atlantic blue marlin (Makaira nigricans), Indo-Pacific sailfish (Istiophorus platypterus) and striped marlin (Kajikia audax) – and provide detailed evidence for the presence of an oil gland in the last three. All four species had a high...

In memoriam Prof. Dr J.T. Wiebes (1931-1999), evolutionary biologist and systematic entomologist Naturalis
Bruggen, A.C. van; Achterberg, C. van.
Born on 13 September 1931 in Rotterdam, Jacobus Theodorus [Koos] Wiebes read biology at Leiden University where he obtained his Ph.D. in 1963 on studies of Indo-Australian fig wasps. He started working on spiders (Lycosidae, Pisauridae) and beetles (Carabidae, Cetoniidae, Helodidae), but he earned his scientific reputation as a specialist in fig wasps (Hymenoptera: Agaonidae, Torymidae), their parasitoids and intricate host relationships (1961-1994: 89 papers). He served for many years on the staff of the Rijksmuseum van Natuurlijke Historie, Leiden (1955-1970, initially as assistant, later as curator of Coleoptera and as assistant director since 1965), to return as director of the newly merged national zoology and geology museums (ad interim 1982-1984,...

Agricultural Sustainability and the Introduction of Genetically Modified Organisms (GMOs) AgEcon
Tisdell, Clement A..
In order to cater for the predicted growth in global population and aspirations for increased living standards, the world needs to increase substantially its level of agricultural production and sustain agriculture’s increased productivity. New technologies may enable this to occur but they also bring with them increased sustainability problems. There are many complex dimensions to achieving agricultural sustainability such as deciding on what agricultural attributes are worth sustaining and considering what trade-offs in objectives are required. These issues are discussed from a conceptual point of view. It is also shown using economic theory that market-based agriculture limits the opportunity for individual farmers to adopt sustainable agricultural...

Biting the hand that feeds you: wedge-billed hummingbird is a nectar robber of a sicklebill-adapted Andean bellflower Acta Amazonica
BOEHM,Mannfred M.A..
ABSTRACT I report on nectar robbing behavior of the wedge-billed hummingbird, Schistes geoffroyi (Trochilidae) on the Andean bellflower, Centropogon granulosus (Campanulaceae). Many species of Centropogon are characterized by an abruptly curved corolla tube which is likely specialized for pollination by sicklebill hummingbirds (Eutoxeres), as evident from the matching curvature of flower and bill. Nectar robbing has been documented for some Centropogon spp., but not for sicklebill pollinated C. granulosus. Given recent developments and interest in the Centropogon-sicklebill mutualism, it is pertinent to document any natural history observations that may underlie the ecology and evolution of this pollination system. The establishment of wedge-billed...

Plant-insect interactions: an evolutionary arms race between two distinct defense mechanisms Braz. J. Plant Physiol.
Mello,Marcia O.; Silva-Filho,Marcio C..
In this review, plant-insect interaction is discussed as a dynamic system, subjected to continual variation and change. Plants developed different mechanisms to reduce insect attack, including specific responses that activate different metabolic pathways which considerably alter their chemical and physical aspects. On the other hand, insects developed several strategies to overcome plant defense barriers, allowing them to feed, grow and reproduce on their host plants. This review foccuses on several aspects of this complex interaction between plants and insects, including chemical-derived substances, protein-derived molecules and volatile compounds of plants whereas metabolization, sequestration or avoidance are in turn employed by the insects.
