IntroductionA population’s demographic “type” is characterized by the shape of its age distribution. This structure provides insights into its behavioral ecology, such as how elderly individuals contribute to the s...

Amphibian populations are declining globally. In this scenario, detailed informationon their ecology is crucial to determine the status and extinction risk of their populations and,therefore, better plan conservation act...

Aun cuando solo quedan menos de 500 ejemplares de huemul patagonico (Hippocamelus bisulcus) en Argentina, existe escasa información sobre su ecología y dinámicas poblacionales. Por primera vez en la historia de Argent...

ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their eco...

The aim of this paper is to expand the current knowledge on the distribution, ecology and morphology of Pseudostaurosira cataractarum (Hustedt) C.E. Wetzel, E. Morales et Ector. We analysed several freshwater diatom asse...

A rising human impact alters landscape patterns and determines the agriculture–ecology–economy nexus (AEEN), which further threatens the sustainability of social–ecological system (SES). However, the mechanisms thr...

For large herbivores, predation-risk, habitat structure and population density are often reported as major determinants of group size variation within and between species. However, whether the underlying causes of these ...

The choice of sampling method is essential in the development of a population genetic study. This choice influences the type of samples that can be obtained and, therefore, the quality of the extracted DNA. Sampling meth...

Abstract Obtaining accurate population measures of endangered species is critical for effective conservation and management actions and to evaluate their success over time. However, determining the population size and de...

In recent decades, escalating climate change, continuous population growth, rapid urbanization, and extensive agricultural development have placed increasing pressure on global ecosystems. Particularly in China, intensiv...

Abstract Adélie penguin (Pygoscelis adeliae) colonies can be detected from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery, as the contrast between their guano and the surrounding te...

The article presents a concise biography of the outstanding botanist and educator, Professor Alexey Aleksandrovich Uranov, founder of the scientific school of plant population biology. Memoirs of A. A. Uranov’s student...

Forests play an important role in water and carbon cycles in semiarid regions such as the Mediterranean ecosystems. Previous research in the Chilean Mediterranean forests revealed a break point in 1980 in regional tree-r...

Selenium (Se) is required at a fundamental physiological level in all animals. Adequate levels of Se are necessary for proper bone metabolism, iodine metabolism, immune function, reproductive success, and recruitment. Se...

The effectiveness of ecological researches on small mammals strongly depends on trapping techniques to survey communities and populations accurately. The main goal of this study was to assess the efficiency of three type...

Dr. Carla Riva-Rossi has over 25 years’ experience studying the evolutionary ecology of anadromous fishes. She received an MS in biological sciences from the Facultad de Ciencias Naturales, Universidad Nacional de la P...

Peninsula Valdes, Argentinian Patagonia, is an area used as a trophic stopover by several shorebird species. These shorebirds are characterized by made long migrations and their survival depend for the sites where they s...

Benthic cyanobacteria research in high mountain reservoirs remains limited, mainly due to their complexity and knowledge gaps that persist in relation to their ecology in tropical regions. This study aimed to explore the...

Transformation of grape must into wine is a process that may vary according to the consumers' requirements. Application of cold soak prior to alcoholic fermentation is a common practice in cellars in order to enhance fla...

Identifying the factors that promote the success of biological invasions is a key pursuit in ecology. To date, the link between animal personality and invasiveness has rarely been studied. Here, we examined in the labora...

Recent studies of the Middle and Upper Paleolithic in the northwestern Caucasus are focused on the research of relations between natural (climate and environment) and social (behavior and adaptations) factors that govern...

Understanding the knowledge, attitudes and perceptions of the local communities towards the target species before implementing any awareness-based programmes is essential for the success and long-term protection of the s...
