(Ediciones INTA, 2017-12)Referentes nacionales y extranjeros reconocen las contribuciones del Dr. Joaquín Mueller a la producción ovina nacional y destacan su pasión profesional, compromiso con el productor, compañerismo con sus colegas y generosidad ... -
Flexible foraging decisions made by workers of the social wasp Vespula germanica (Hymenoptera: Vespidae) in response to different resources: influence of ontogenetic shifts and colony feedback
(Wiley, 2022-04)Decisions made by foraging animals conform a complex process based on the integration of information from multiple external environmental stimuli and internal physiological signals, which in turn are modulated by individual ... -
Flight capabilities of invasive yellowjacket Vespula germanica drones: the effect of kinship and nutrition
(Wiley, 2024-01)Dispersal is a multifactorial process which may influence, among several others, population dynamics, inbreeding likelihood, and mate competition. For species that disperse by flight, many studies have suggested that ... -
Following the star: Inflorescence heliotropism
(Elsevier, 2018-03)Plant movements in response to directional solar radiation, known as “heliotropism” are frequently observed in nature. Although there is a considerable amount of literature on these movements in vegetative organs, knowledge ... -
Food and Host Searching Decisions Made by Ibalia leucospoides (Hymenoptera: Ibaliidae), a Parasitoid of Sirex noctilio (Hymenoptera:Siricidae)
(2012-07)During their adult life, parasitoids—insects that lay eggs in or on other arthropods eventually killing them- spend a significant proportion of their lifetime searching for hosts, this behavior will determine their future ... -
Food habits of Oligoryzomys longicaudatus (Rodentia) in a steppe–forest transitional area of Argentinean Patagonia
(Asociación Argentina de Ecología, 2014)We described the spatial and seasonal variation of feeding habits of Oligoryzomys longicaudatus in four environments of the steppe-forest transition zone of Argentinean Patagonia. Composition of fecal pellets collected ... -
Food partitioning between the Mara (Dolichotis patagonum) and the introduced hare (Lepus europaeus) in the Monte desert, Argentina
(Taylor & Francis, 1997)In the semiarid Monte desert, Río Negro province, the mara (Dolichotis patagonum) and the European hare (Lepus europaeus), which was introduced about hundred years ago, today occur sympatrically, as in many regions of ... -
Foot-and-Mouth Disease: Optimization, Reproducibility, and Scalability of High-Yield Production of Virus-Like Particles for a Next-Generation Vaccine
(Frontiers Media S.A., 2020-09)Inactivated Foot-and-Mouth Disease (FMD) vaccine has proven to be effective in the control of the disease. However, its production has some disadvantages, including the costly biosafety facilities required for the production ... -
Forage ofering and seasonal intake comparisons to evaluate European rabbit threat in Nothofagus forests of southern Patagonia
(Springer Nature, 2022-07-05)Background: The European rabbit (Oryctolagus cuniculus L. 1758) was introduced into diferent regions of the world, generating signifcant trade-ofs that critically impacted native vegetation. Here, we evaluate the rabbit’s ... -
Foraging behavior interactions between two non-native social wasps, Vespula germanica and V. vulgaris (Hymenoptera: Vespidae) : implications for invasion success?
(2016-01)Vespula vulgaris is an invasive scavenging social wasp that has very recently arrived in Patagonia (Argentina), a territory previously invaded – 35 yrs earlier – by another wasp, Vespula germanica. Although V. vulgaris ... -
Foraging niche separation of social wasps in an invaded area: Implications for their management
(Wiley Online Library, 2019-10)Foraging niche separation may be a mechanism to promote coexistence of two competing species by concentrating intraspecific competition relative to interspecific competition. The present study investigated foraging behaviour ... -
Forest active restoration for silvopastoral use in Northwestern Patagonia: relative importance of the nurse effect
(Springer, 2023-03)Ecological interactions, such as facilitation among plant species, has been identified as key for restoration actions. The stress-gradient hypothesis predicts that facilitation increases under harsh environments, but ... -
Forest Health in the Southern Cone of America: State of the Art and Perspectives on Regional Efforts
(MDPI, 2023-04)The plantation and natural forests of South America have been highly impacted by native and exotic pests in recent decades. The interaction of emerging invasive pests, climate change, and timber markets will define the ... -
From farm scale to village scale trade-offs : cereal crop residues use in an agro-pastoral system of the Sudanian zone of Burkina Faso
(2015-03)Traditionally, cereal crop harvest residues are communally grazed by the ruminant herds of villagers and transhumant pastoralists in the agro-pastoral systems which predominate in the savannah zone of West Africa. We ... -
From traditional knowledge to novel adaptations of transhumant pastoralists the in face of new challenges in North Patagonia
(Elsevier, 2018-10)Transhumant pastoralism is a mobile livelihood strategy in many mountainous, arid and semi-arid regions worldwide. The knowledge of pastoral communities and their lifestyle are strongly rooted in the historical evolution ... -
Functional and histopathological changes induced by intraparenchymal injection of kainic acid in the rat cervical spinal cord
(Elsevier, 2015-05)Kainic acid (KA) is an analog of the neurotransmitter glutamate and is widely used as an excitotoxic agent to lesion spinal cord networks, thus, providing an interesting model to learn basic mechanisms of spinal cord injury. ... -
Functional diversity of phytochrome family in the control of light and gibberellin-mediated germination in Arabidopsis
(Wiley, 2014-03)In several species, seed germination is regulated by light in a way that restricts seedling emergence to the environmental conditions that are likely to be favourable for the success of the new individual, and therefore, ... -
Functional farm household typologies through archetypal responses to disturbances
(Elsevier, 2020-02)Methods to construct farm household typologies may differ in their approach but they share a common feature: they rely mostly on structural farm data. Methods to build functional typologies are far less abundant. Households ... -
Functional Traits Mediate the Natural Enemy Response to Land Use at the Local Scale
(MDPI, 2023-05)Arthropods are key nodes for the provision of ecosystem services such as pest control, but their response to land-use change is highly variable depending on the scale of analysis and the natural enemies’ life histories. ... -
