Eco‐evolutionary dynamics of partially migratory metapopulations in spatially and seasonally varying environments

open access: yesJournal of Animal Ecology, EarlyView.
Partial seasonal migration is rarely considered in a metapopulation context. Here, Haaland et al. use an eco‐evolutionary model revealing how partially migratory metapopulations may arise and be maintained, and how seasonal migrants may cause effects of local extreme climatic events to percolate through metapopulations across diverging temporal and ...

The importance of physiology on insect geographical distribution [PDF]

open access: yes, 2015
Hallar la explicación de los patrones de distribución de especies a gran escala es un tema muy importante en ecología. Existen muchos trabajos mostrando correlaciones entre factores abióticos, latitud y/o altitud y distribución de especies.

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

open access: yesArchaeometry, EarlyView.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

Longevity and Growth of the Crabs Callinectes sapidus and Callinectes rathbunae (Decapoda: Portunidae) in Paraíso Tabasco Mexico

open access: yesActa Zoologica, EarlyView.
ABSTRACT Individual growth models are important in fisheries of natural populations and can be incorporated in production models to estimate their maximum sustainable yield. Blue crab species, Callinectes sapidus and Callinectes rathbunae were obtained in the Mecoacán lagoon, Paraíso, Tabasco Mexico by “nasa” and “yahual” nets. Biometric values such as

Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

open access: yesEcological Entomology, EarlyView.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .

Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

open access: yesJournal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...

The emergence of pathogens on fish in an impacted estuary and the role of non‐native piranhas in a potential bacterial infectious outbreak

open access: yesJournal of Fish Biology, EarlyView.
Abstract As many tropical aquatic ecosystems worldwide, the Doce River estuary (DRE, southeastern Brazil) has increasingly faced multiple anthropogenic threats, including deforestation, mining, species introduction and water management. The 2015 collapse of the Fundão iron ore tailings dam severely changed water properties and increased heavy metal ...
