Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Identifying Priority Areas for Biodiversity and Soil Accumulation Ecosystem Service Management in Tropical Forests with High Global Conservation Priority

open access: yesJournal of Landscape Ecology
The Mira River watershed in northern Ecuador is located within the Tropical Andes and Tumbes-Chocó-Magdalena hotspots. This landscape provides many ecosystem services necessary for human well-being.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Estimating the Resilience Value of Soil Biodiversity in Agriculture: A Stochastic Simulation Approach [PDF]

open access: yes
Characteristic of ecosystems is that different organisms can have similar functions and hence provide similar ecosystem services. Consequently functional diversity can maintain the rate of services despite environmental fluctuations.

Organic farming systems benefit biodiversity and natural pest regulation in white cabbage [PDF]

open access: yes, 2010
Natural regulation of cabbage root flies works well in experimental organic cropping systems of white cabbage. Low input and complex organic systems benefit functional biodiversity by providing good living conditions to several groups of natural enemies.

Automated pre-processing strategies for species occurrence data used in biodiversity modelling [PDF]

open access: yes, 2010
To construct Biodiversity richness maps from Environmental Niche Models (ENMs) of thousands of species is time consuming. A separate species occurrence data pre-processing phase enables the experimenter to control test AUC score variance due to species ...

The role of soil community biodiversity in insect biodiversity [PDF]

open access: yesInsect Conservation and Diversity, 2010
Abstract.  1. This study demonstrates that feedback loops between plants and insects contribute to both plant and insect diversity. Synthesis of several studies reveals that both bottom‐up and top‐down forces are important for plant and insect communities. 2.
