Abstract National‐scale benthic marine habitat maps underpin monitoring and conservation of vulnerable marine and coastal ecosystems. Cloud‐based satellite remote sensing can streamline these processes over spatial s...

Se denomina imposex a la aparición de caracteres sexuales secundarios en hembras de neogasterópodos producidos por laexposición a tributil-estaño (TBT). No existen hasta la fecha reportes de este fenómeno en el Cari...

ABSTRACT The biochemical defense mechanisms of amphibians involve cutaneous secretions of bioactive molecules with antimicrobial activity. This study evaluated the in vitro activity of methanolic extracts from cutaneous ...

Marine reserves (areas closed to fishing) have been advocated for the management of many species, including the rock scallop Spondylus calcifer in the northern Gulf of California (NGC), Mexico. We developed an explicit c...

Being the main oil-bearing basin of Argentina, the Neuquén Basin contains a well-documented stratigraphic record of continental and marine sedimentation during the Jurassic and Cretaceous in the western margin of Gondwa...

Marine communities are changing at an accelerated rate because of anthropogenic stressors such as global warming and overfishing. Community compositional change over time (temporal β diversity) is mainly driven by the r...

Cystoliths are phytoliths of silica and calcium carbonate and are produced in a few groups of dicotyledonous angiosperms. Anatomical and, more recently, phytolith studies have recorded them in different families. In the ...

Feeding decisions under predation risk can be a key in the life of scavenger organisms, and tuned recognition of predation alarm cues and flexibility in the response are fundamental. The effect of injured conspecifics on...

The importance of small-scale heterogeneity in local factors which overrides that of larger-scales factors, suggest that local factors play a major role in determining the richness and prevalence of larval digeneans in i...

We describe qualitatively and quantitatively the copulatory pattern of Ctenomys talarum (tuco-tuco) and evaluate it according to that expected for induced ovulators. Mating trials were performed in an experimental appara...

The Chubut River is a Patagonian river that flows from the Andes to the Atlantic Ocean, and is interrupted by a dam built at the middle valley. To investigate the sedimentary history of the lower river basin, a sediment ...

Glucocorticoids participate in the behavioral and physiological responses generated under stressful circumstances coming from different sources—physical and/or psychological. In mammals, the increases of these hormones...

Microplastics are currently considered widespread marine pollutants, accumulating in sediments and shorelines around the world. Spatial distribution of microplastics in marine sediments is consequence of a combination of...

The pattern of somatic growth reflects the variable allocation of energy and materials throughout ontogeny, with direct impact on an individual’s fitness, and is therefore expected to be adaptive with regard to the dif...

The Pampeano aquifer formed by loess-like sediments provides water to cities and for agricultural uses in the Pampean plain, which is the most productive area in Argentina. Studies on the mechanisms through which this gr...

In marine science and engineering, growing volumes of imaging data are used in exploration and monitoring. The process of manual annotation of this data (i.e. marking and describing objects of interest with labels), to e...

The Late Quaternary North Sea basin represents a highly dynamic shelf system, altered by glaciations, deglaciations, and the recent Early Holocene marine transgression. However, detailed studies on the timing of the mari...

Nest survival is an important part of breeding success in grassland ecosystems, and the location of nests can determine vulnerability to different predators. We conducted an experiment with artificial nests to evaluate j...

The monophyletic group Caviomorpha constitutes the most diverse rodent clade in terms of locomotion, ecology and diet. Caviomorph species show considerable variation in cranio-mandibular morphology that has been linked t...

From molecular determination we can confirm that the stranded bird analyzed corresponded toa Thalassarche steadi individual. This identification method has been previously implemented in themolecular determination of shy...

During ontogeny, complex adaptations undergo changes that sometimes entail different functional capabilities. This fact constrains the behaviour of organisms at each developmental stage. Rodents have ever-growing incisor...

Abstract Anthropogenic emissions may drive the isotopically light zinc that pervades the low-latitude upper ocean, but major gaps in our understanding of oceanic zinc cycling have hindered the unequivocal detection of an...

Is it possible to contribute carbon neutral by yeasts inhabiting in aquatic environments of our neighborhood? In COP26, held from October to November in 2021, various concrete attempts by participating countries were pro...

Introduction: In recent decades, Caribbean coral reefs have lost many vital marine species due to diseases. The well-documented mass mortality event of the long-spined black sea urchin Diadema antillarum in the early 198...
