Background and aims: Macroptilium is an herbaceous legume genus with eighteen currently accepted species, seven of them with economic importance due to their use as forage, green fertilizer and in medicine. The genus is ...

The Miridae (Hemiptera: Heteroptera) are one of the most species rich families of insects, with about 11 100 described species. Mirinae is the largest subfamily and its endemism becomes evident at the tribal level and be...

The distribution of the recent Lymnaeidae across continents and zoogeo-graphical regions of the world is reviewed, with a brief characteristic of the geo-graphical distribution of each extant lymnaeid genus. The quantita...

Species of Pleurobranchus (Mollusca: Gastropoda: Heterobranchia: Nudipleura: Pleurobranchidae) are commonly found worldwide, but there is a substantial amount of confusion regarding the ranges and identification of indiv...

Recent studies have described widespread statigraphic units of Late Pleistocene and Holocene age in the western part of the Amazon Basin. The recognition of deltaic sedimentation in the uppermost these units near Rio Bra...

Abstract The family Anisakidae includes parasite genera that are important for public health due to their zoonotic potential. Among these, the genus Anisakis contains some of the most prevalent parasites found in fish th...

Abstract In Brazil there are several records of parasitic nematodes of fish with zoonotic potential, especially those belonging to the family Anisakidae. This study considers the morphology, morphometry and prevalence o...

In recent years, the evolutionary history of the catfish genus Hypostomus has attracted much interest. However, the identification of species of this genus is challenging, given the complex taxonomy of the group and the ...

ABSTRACT Soil, topography, and climate have been identified as strong drivers of functional composition turnover of plant communities, setting the dominant (“optimal”) community weighted mean (CWM) trait values. Thes...

Biogeographic studies have generally relied on methods that use a few, large predefined areas, which may overlook fine-scale patterns. Here we test previous hypotheses about the biogeographic history of a diverse bat c...

The presence of three Gomphoneis species from Chubut Province in Argentina is documented with light and scanning electron microscopy. Two of the taxa, G. patagoniana and G. eriense var. variabilis, are part of the Hercul...

The trigoniid group "Pseudo-Quadratae" was introduced for Cretaceous descendents of Myophorellidae with a convergent resemblance to Tethyan Quadratotrigoniinae (= Quadratae). Subsequently it was made the basis of the sub...

To analyse speciation within the large Neotropical genus Campsurus Eaton, we examined apparent subgroupings by morphological methods using discrete and continuous character states. In this report, the albifilum group is ...

Pliocene marine mollusk faunas from Chile are mainly known from the Coquimbo Formation of central Chile. Three new early to middle Pliocene mollusk faunas from Mejillones Peninsula (northern Chile), the Navidad area (cen...

During the Jurassic the teleost fishes went through their first important radiation and colonization of continental environments. Due to a bias in the geological record, Jurassic fresh-water deposits are very scarce, and...

The West Indies are a natural laboratory for the study of biogeography and evolution, especially for mammals. The modality of their arrival in the Caribbean islands is a highly controversial issue, and palaeontological e...

Adapisoriculidae, a family of primitive eutherian, insectivore-like small mammals, is known from Europe, mainland Asia, India and Africa (Morocco, Namibia) but not thus far from the New World. Previous discoveries of thi...

Honey bees critically impact global food security as pollinators in agricultural systems worldwide (Aizen and Harder, 2009; Potts et al., 2016). They are also considered one of the most successful invasive organisms, hav...

Gastropoda, with approximately 80,000 living species, is the largest class of Mollusca. Among gastropods, apple snails (family Ampullariidae) are globally distributed in tropical and subtropical freshwater ecosystems and...

Este trabajo pretende identificar el impacto generado por la práctica del turismo en los Esteros del Iberá (Pcia. de Corrientes). El área presenta una diversidad de paisajes originados en complejas interrelaciones e...

ABSTRACT The Amazonian megadiversity remains understudied and underestimated due to the region’s vast size, environmental heterogeneity, and inaccessibility. With increasing threats to the biome, it is crucial to map c...

Fog oasis is an ecosystem composed of abundant and seasonal xerophilous herbaceous vegetation, which are exclusively distributed as vegetation patches throughout the coastal deserts of Peru and Chile. Fog oases present a...

THE study of Gondwanan non-avian theropods has beenoutstandingly prolific in the last three decades and hasshown that the taxonomic and morphological diversity ofthe group is comparable to that of Laurasia. The MesozoicG...

Abstract Accurate prediction of compressive strength is important for the efficient design of sustainable concrete incorporating palm oil fuel ash (POFA). This study developed a hybrid artificial neural network model opt...
