Tree Squirrels Selectively Disperse High‐Quality Acorns Away From Tree Trunks

open access: yesIntegrative Zoology, EarlyView.
Acorn quality and squirrel feeding behavior significantly structured spatial dispersal patterns of two Californian oak species. Non‐infested acorns were preferentially selected for embryo excision and dispersed farther than infested ones. Acorns were fully consumed near tree trunks, signaling rapid feeding in safe refuges, whereas non‐eaten, partially ...

The Australian Hydromyine Rodents—Their Interspecific Diversity and Reproductive Biology: A Review

open access: yesIntegrative Zoology, EarlyView.
There are two major groups, the Rattus species and the Hydromyini, in Australia. Clearly, the hydromyine rodents, unlike the Rattus genus, exhibit a diverse array of reproductive biological traits in both males and females, the full evolutionary significance of which has yet to be ascertained.

The stability of various community types in sand dune ecosystems of northeastern China

open access: yesRevista de la Facultad de Ciencias Agrarias, 2017
The stability of artificial, sand-binding communities has not yet fully studied. A similarity index was developed to evaluate the stability of artificial communities in shifting and semi-fixed sand dunes. This similarity index consisted of 8 indicators (

Some Tuco‐Tucos Hide More Than Others: An Integrative Approach Reveals Cryptic Diversity in Ctenomys (Rodentia: Ctenomyidae) From Central Argentina

open access: yesIntegrative Zoology, EarlyView.
Here, we adopt an integrative framework (molecular phylogenetics and geometric morphometrics) to reassess patterns of diversity and differentiation across this region. We analyzed cytochrome b sequences and quantified cranial shape variation. Our analyses indicate the presence of three species groups (mendocinus, talarum, and tucumanus) and two ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

open access: yesArchaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.
