Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

open access: yesIntegrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Uncovering the Process of Sexual Segregation: Male Early‐Life Individual Tactics Shape Its Onset and Affect Phenotypic Quality in a Large Mammal

open access: yesIntegrative Zoology, EarlyView.
Early‐life traits significantly influence sexual segregation patterns and phenotypic quality in male fallow deer. Males in better condition and those more risk‐prone left natal groups earlier with fewer returns to natal groups. However, males with frequent excursions back to natal groups compensated for initial body condition disadvantages.

Goby gummies: A customizable and edible assay to quantify predation in aquatic ecosystems

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Predation is a critical ecosystem process that shapes the structure and functioning of biological communities. However, due to its intermittent nature, fast pace and general unpredictability, predation is difficult to observe and quantify. Therefore, we commonly rely on indirect metrics or proxies of predation, which reflect the outcome of ...

Integration of LIDAR and IFSAR for mapping [PDF]

open access: yes, 2004
LiDAR and IfSAR data is now widely used for a number of applications, particularly those needing a digital elevation model. The data is often complementary to other data such as aerial imagery and high resolution satellite data.

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

open access: yesAnimal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Mapping Palaeolithic Imprints: Spatial Analysis of Hand Stencils in El Castillo Cave (Spain) Through Geomatic Techniques

open access: yesArchaeometry, EarlyView.
ABSTRACT We present the application of a new quantitative approach to space study in Palaeolithic cave art. Using GIS, we analysed the distribution and position of hand stencils in El Castillo cave to track the gestures and behaviours of Palaeolithic societies.

A Newly Discovered Tablet‐Making Facility in Nineveh: Insights From Scientific Analysis

open access: yesArchaeometry, EarlyView.
ABSTRACT This paper addresses the question of tablet technology in the Neo‐Assyrian capital city of Nineveh. Recent excavations in the lower town of Nineveh by the Iraqi–Italian Archaeological Expedition uncovered an exceptional assemblage of more than 200 tablets from an elite residence that appears to have included a scriptorium.
