On the compatibility of single‐scan terrestrial LiDAR with digital photogrammetry and field inventory metrics of vegetation structure in forest and agroforestry landscapes

Remote Sensing in Ecology and Conservation, EarlyView.
The single‐scan approach to terrestrial laser scanning (TLS) and the self‐terrain‐normalized form of drone‐based digital aerial photogrammetry (DAP) offer practical options for rapid assessment of the vegetation structure in tropical landscapes.

Comparison of Norway spruce (Picea abies [L.] Karst.), Scots pine (Pinus sylvestris L.) and European larch (Larix decidua Mill.) stem shape by means of geometrical methods

Journal of Forest Science, 2006
In this article the stem shape is compared in three coniferous tree species: Norway spruce, Scots pine and European larch. Stem is investigated by means of geometrical methods.

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

Journal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Traditional and Geometric Morphometrics and Invariant Shape Descriptors of Catfish Otoliths in the Yucatán Peninsula: Tools for Species Identification and Individual Size Estimation at Maya Archaeological Sites

Archaeometry, EarlyView.
ABSTRACT This study investigates the use of otolith shape analysis for species identification and size estimation in Ariopsis felis and Bagre marinus, based on 181 modern otoliths obtained from a scientific collection and recent sampling in the coastal regions of Campeche and Yucatán, as well as 39 archaeological otoliths corresponding to the Early ...

Maxillary first premolar shape (and not size) as an indicator of sexual dimorphism: A 2D geomorphometric study [version 3; peer review: 2 approved, 1 not approved]

F1000Research
Introduction The primary aim of the study is to evaluate the morphological form of the maxillary first premolar using 2D geomorphometry and evaluate the sexually dimorphic characteristics.
