El monitoreo acústico pasivo (PAM), mediante el uso de grabadores autónomos, es un método no invasivo que permite obtener información de forma continua, simultánea y en diversas condiciones ambientales. Estas características favorecen su uso para monitoreos ecológicos, pero su efectividad aún presenta desafíos propios de una disciplina en desarroll...

Diadumene lineata is one of the most widely distributed sea anemones in the world. It is usually found in estuaries, gulfs and bays over a broad range of substrates such as oysters, rocks, seaweeds and docks. In this study, we report the presence of D. lineata in a rocky outcrop located on an open ocean sandy beach on the Argentinian coast. We anal...

We developed an inexpensive light instrument (ILI) and protocol for the measurement of photosynthetically active radiation (PAR) at discrete depths underwater. We tested the accuracy of the ILI against a submersible radiometer (RAD) and a Secchi disk method. The ILI consists of a PAR sensor (HOBO MX2202; Onset) attached to a flat disk that ensures...

Relations among polycyclic aromatic hydrocarbons (PAHs), biomarkers of oxidative stress (lipid peroxidation, glutathione, and glutathione S-transferase activity), and the possible influence of environmental factors (temperature, pH, and salinity) were assessed in situ for specimens of Ramnogaster arcuata, a native estuarine fish. PAH levels found i...

This study explores the effect of different wind events (direction and duration) on the surf zone zooplankton community in a temperate sandy beach. Samplings were realized on the surf zone of Pehuen Co sandy beach during 17 wind events from May 17th, 2017, to July 19th, 2019. Biological samples were taken before and after the events. The identifica...

Climatic variability and anthropogenic pressures impact the structure and dynamics of pelagic ecosystems and copepods are good indicators of such changes. This investigation aims to explore the interannual pattern of the mesozooplankton community, in relation to environmental variables in the Bahía Blanca Estuary during winter-spring from last two...

Biological invasions represent one of the most significant threats to the conservation of biological diversity. Understanding the population dynamics of an invasive species is essential to detecting key components that allow the development of an effective management strategy. South American Pampas are particularly vulnerable to the invasion by ali...

In the southwestern Atlantic Shelf, in northern Patagonia, the coastal-inner shelf area of El Rincón (38°-41°S) is relevant due to retention processes and the occurrence of a mid-shelf front (MSF), which provide favorable habitat for the anchovy Engraulis anchoita, from which other commercial species feed on. Here, we assess the protistan plankton...

Natural regeneration is a critical step for the dispersal of alien plants and the establishment of new invasive foci. The adequate timing and location of germination, as well as the survival of the seedlings, have direct effects on the recruitment of the population, and are expected to depend on habitat characteristics. Understanding the dynamics o...

The driving forces behind many soil processes are microorganisms and they are able to respond immediately to environmental changes. The soil microbial community impacts on many soil properties. More than one-third of the terrestrial ecosystems are semiarid. However, a limited number of studies have been conducted to characterize soil fungal communi...

Shallow biogenic gas deposits located in the surface of the seabed may affect abundance, diversity, biomass and structure of benthic communities. Nevertheless, the magnitude and responsible variables of this effect still not clear. For this, the current study applies sedimentological metrics to the different community patterns associated with gas p...

Biological invasions are one of the most important challenges for protected areas around the world, both because of the seriousness of their effects and because of the costs and difficulties associated with their control. Some features of the biology of invasive species, such as growth rate and reproduction, can be particularly important when organ...

Surf zones of sandy beaches are poorly studied in comparison to estuarine and continental shelf waters, specifically because of the difficulties experienced in sampling in high-energy environments. The zooplankton of these areas, therefore, has received less attention than that in other coastal systems. The aim of this study was to investigate the...

Invasiveness has usually been studied as a species-level attribute; nevertheless, phenotypic differences between individuals in a population can lead to significant variations in colonization ability. In this paper, we analyse the potential effects of sex morphs of Prunus mahaleb L., a gynodioecius fleshy-fruited tree, on its invasiveness in natura...

Plants with animal-dispersed fruits seem to overcome the barriers that limit their spread into new habitats more easily than other invasive plants and, at the same time, they pose special difficulties for containment, control or eradication. The effects of animals on plant propagules can be very diverse, with positive, neutral or negative consequen...

Irrigation regime applied in the experimental garden trial. It shows the total amount of water used per month for Prunus mahaleb stones sown at Jardín Botánico Pillahuincó, Ernesto Tornquist Provincial Park. (DOCX)

Data set of the germination test carried out in the experimental garden. It contains the occurrence of seedling emergence (Emergence, binary), for each individual seed initially sown (ID), for the different treatments considered (Treatment) and days after sowing (Days). (CSV)

Data set of the percentage of pulp vestiges observed on stones treated by dispersers. It contains the estimated percentage of the stone surface that was covered with pulp vestiges (pulp.vestiges), using five categories (0%, under 25%, 25–50%, 50–75%, above 75%), for the different species (Species). (CSV)

Images of stones treated by different dispersers. The pictures show different amounts of pulp vestiges adhered to the stone surface for Prunus mahaleb treated by different dispersers: Acromyrmex lundi (A), Tyrannus savana (B), Mimus saturninus (C), Pitangus sulphuratus (D), Patagioenas maculosa (E), Lycalopex gymnocercus (F), hand-peeled stones (G)...

Data set of the germination test carried out under laboratory conditions. It contains the number of germinated seeds from a total of 20 initial seeds (Ngerminated), for each replicate (Replicate), for the different treatments considered (Treatment) and days after sowing (Days). (CSV)

Soil microorganisms are vital for ecosystem functioning because of the role they play in soil nutrient cycling. Agricultural practices and the intensification of land use have a negative effect on microbial activities and fungal biomass has been widely used as an indicator of soil health. The aim of this study was to analyze fungal biomass in soils...

http://onlinelibrary.wiley.com/doi/10.1111/wre.12171/abstract Prunus mahaleb (Saint Lucie's cherry) is a fleshy-fruited small rosaceous tree, native to the Mediterranean region that has been extensively used as a rootstock species for commercial orchard trees. It has been widely introduced in several countries, becoming invasive in many regions, i...

Natural grasslands are one of the ecosystems that have suffered the most intense series of human changes, even though they have not received enough conservation efforts. The proliferation of invasive shrubs and trees over grasslands and savannas around the world has been one of their severest modifications during the last century. The last remnants...

Throughout human history, people have developed the faculty to appreciate and create music. Musical thinking implies the development of cognitive and emotional faculties by complex neural processes. How could such a complex behavior as music be originated by evolution? This article reviews the main evolutionary approaches that have been proposed to...

A lo largo de la historia evolutiva del humano, surgió una facultad que actualmente y a nivel universal nos permite apreciar y crear música. El pensamiento musical implica un desarrollo de las facultades cognitivas y emocionales de un individuo a través de procesos mentales complejos. ¿Cómo pudo originarse un comportamiento así en el curso de la ev...

Invasive success of many fleshy-fruited plants has been linked to opportunistic interactions with generalist frugivores. Prunus mahaleb is a small tree, producing large quantities of little, bright black, sugary drupes that are consumed by vertebrates. It is native to the Mediterranean region but has become invasive in several countries. This study...
