Laringuectomía total y traqueostomía permanente en un perro, por un adenocarcinoma laríngeo infraglótico

Perra Rottweiler de 8 años de edad con historial de cansancio progresivo y dificultad respiratoria. Tras una exploración física y radiológica se sospechó la presencia de una masa en la luz de la laringe que se confirmó con la exploración directa. Se realizó una citología y el informe anatomopatológico indicó que presumiblemente se trataba de una neoplasia de carácter maligno. Se realizó una laringuectomía total conjuntamente con una traqueostomía permanente. La evolución fue satisfactoria pero a los 12 días del alta, el paciente falleció de muerte súbita

Colonisation in social species: the importance of breeding experience for dispersal in overcoming information barriers

Este artículo contiene 7 páginas, 3 figuras, 1 tabla.Studying colonisation is crucial to understand metapopulations, evolutionary ecology and species resilience to global change. Unfortunately, few empirical data are available because field monitoring that includes empty patches at large spatiotemporal scales is required. We examine the colonisation dynamics of a long-lived seabird over 34 years in the western Mediterranean by comparing population and individual data from both source colony and the newly-formed colonies. Since social information is not available, we hypothesize that colonisation should follow particular dispersal dynamics and personal information must be crucial in decision making. We test if adverse breeding conditions trigger colonisation events, if personal information plays a role in colonisation and if colonisers experience greater fitness. Our results show a temporal mismatch between colonisation events and both density-dependence and perturbations at the source colony, probably because colonisers needed a longer prospecting period to compensate for the lack of public information. Colonisers were mostly experienced individuals gaining higher breeding success in the new colony. Our results highlight the demographic value that experienced individuals can have on metapopulation dynamics of social longlived organisms.FPU (ref. FPU2012-000869), IBISES (ref.

The role of calcium in constraining egg synthesis in the Audouin’s Gull (Ichthyaetus audouinii)

Understanding how resources are allocated to form eggs is crucial to our better understanding of avian reproductive strategies. However, little is currently known about how egg synthesis in wild birds might be constrained by the availability of specific micronutrients. Here, we investigated the potential role of calcium (Ca) in constraining egg synthesis in the Audouin’s Gull (Ichthyaetus audouinii (Payraudeau, 1826)). In particular, we evaluated the relationship between plasma Ca levels (mg/dL) in incubating females (as an indicator of the physiological response of females to increased Ca demand associated with clutch production) and several fitness-related egg traits such as egg size (i.e., egg volume), egg shape, and eggshell thickness from three-egg clutches. Egg size was positively related with incubating female plasma Ca levels, with the slope of this relationship being significantly higher for later-laid eggs. The observational nature of this study and reversed timing precludes causal inferences, but observed relationships supported the constraining role of Ca in egg synthesis and suggested that Ca may also have a role in modulating the intraclutch pattern of egg-size variation typical of this gull species.Peer reviewe

The bioenergy-fertilizer nexus: a challenge achievable from municipal wastewater

Several billion tons of liquid and solid waste are produced every year globally, contributing to soil and water pollution, greenhouse gas emissions and loss of important nutrients, like C, N and P in the environment. On the other hand, soils are facing a strong reduction of organic matter content while agricultural, food and productive processes mainly rely on external inputs, i.e. mineral fertilizers and chemical pesticides. Biological Wastewater Treatment (WWT) systems play an important role in improving water quality and human health. When properly treated, wastewater is a valuable resource to reduce pollution and combat water scarcity. This chapter aims to give a brief overview of the conventional biological WWT plant and its treatment steps, with a specific focus on the solid residues of WWT plant, i.e. sewage sludge (SS), which could be also valorised by anaerobic digestion (AD), converting it into valuable commercial products: biogas and fertilizers, applying hence the important concept of the Circular Economy. Moreover, we show the effects of application of AD residues (i.e. digestate) on soils with a high risk of desertification, such as with a prevalent sandy texture, with low soil organic matter and high depletion of macronutrients. Results demonstrate fertilizers' effect on poor soils, an issue that is nowadays a persistent environmental problem, with the advancing of desertification and the even more frequent presence of arid soils. The etiological agents of this phenomenon deal with deforestation, urban expansion, unsustainable soil management and climate change, issues that Vietnam and Europe try to solve with different approaches. As result, these soils, even distant, show common features in terms of structure (erosion, compaction), chemical composition (loss of organic carbon, nutrient imbalance) and biodiversity that need to be addressed
