Ecology and sustainability are increasingly approached as a coupled socio-ecological agenda for balancing human needs, ecosystem integrity, and long-term resilience within ecological limits Rapid climate risks, accelerat...

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 Background Movement to spawn in offshore waters provides numerous benefits to inshore marine fish and crustacean species, but there is often limited empirical data on the behaviour and ecology of this key aspect...

Trophic studies are key components in animal ecology and fisheries research. Although stomach samples are often obtained from fisheries, diet studies that consider the influence of fisheries on dietary results are still ...

We conducted a study on the habitat use, food, and feeding ecology of the lesser known Tamdil Leaf-litter Frog Leptobrachella tamdil at its type locality. The places occupied by L. tamdil in the wild are characterised by...

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...

We provide a checklist of angiosperms collected in the Paraná River Delta Region during the 1990s and early 2000s. Plants were taxonomically identified and classified according to their origin (native/endemic and exotic...

Question: A set of easily‐measured (‘soft’) plant traits has been identified as potentially useful predictors of ecosystem functioning in previous studies. Here we aimed to discover whether the screening techniques...

This paper highlights the importance of islands for proposing and testing hypotheses in stream ecology, and therefore, advocates for implementing reference studies in Gorgona Island (Colombian Pacific). It firstly summar...

Monitoring the body condition of ungulates is an important aspect of understanding their ecology as it provides information about habitat conditions, seasonality of nutritional stress, disease susceptibility, and prey se...

Anastrepha fraterculus sp.1 males are sexually stimulated by the aroma of fruit of its native host Psidium guajava (guava). Other hosts, which are exotic to A. fraterculus, do not enhance male sexual behavior. Here we ev...

The genus Arachniodes (Dryopteridaceae) is mainly distributed in tropical Asia, with Indian records largely confined to the Himalaya, northeastern India, and southern Western Ghats. No confirmed report existed from the n...

Identifying the prey species is crucial for successful conservation and landscape-level management of large predators whose feeding ecology is incompletely known. Assessment of faecal samples is a viable method for achie...

La emergencia y la magnitud que los problemas ambientales han ganado en las tres ultimas décadas han posibilitado una gran producción científica acerca del tema de la ecología y el medio ambiente, principalmente en r...

With their ground-nesting habits, the Red-wattled Lapwing Vanellus indicus are particularly vulnerable to urbanization, which ffects their nesting behaviour, reproductive success, and habitat use. The present study was...

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...

Phosphorus (as phosphate, Pi) and iron (Fe) are critical nutrients in plants that are often poorly available in the soil and can be microbially affected. This work aimed to evaluate how plant-rhizobacteria interaction ch...

Desde la época en que emerge la problemática ambiental contemporánea, esta ha devenido en objeto de análisis e intervención tanto para la ecología (en tanto área de la biología) como para distintos organismos int...

Introduction: Land-use changes have transformed many Mediterranean ecosystems in ways that can adversely affect ectotherms such as reptiles. Range-edge reptile populations may be especially sensitive to such changes, as ...

Abstract Background Representatives of the phylum Methanobacteriota occur in various anoxic environments, but only members of the genera Methanosphaera and Methanobrevibacter exclusively colonize the digestive tract of a...

Abstract Alcoholic Heart Disease (AHD) involves gut microbiota dysbiosis, metabolic disturbances, and circadian disruption, yet their interconnections remain unclear. Using a murine AHD model, we integrated echocardiogra...

Understanding the spatial ecology of wide-ranging marine megafauna is essential for identifying critical habitats and designing effective conservation strategies. Whale sharks undertake extensive movements far beyond wel...

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...

In studies on the reproduction and germination of species with indehiscent fruits containing a single seed, it is often assumed that all fruits that reach maturity contain a seed capable of generating a new plant. This i...
