Effects of heterogeneity on the ecological diversity and redundancy of forest fauna

open access: yesBasic and Applied Ecology, 2023
Heterogeneity in forests might promote biodiversity not only through an increase in niche volume but also through other processes, such as an increase in resources and their spatial distribution.

Landscape-scale connectivity and fragment size determine species composition of grassland fragments

open access: yesBasic and Applied Ecology, 2022
As a consequence of agricultural intensification and habitat fragmentation since the mid-20th century, biological diversity has declined considerably throughout the world, particularly in Europe. We assessed how habitat and landscape-scale heterogeneity,

Prey preferences of specialized jumping spiders (Araneae : Salticidae). [PDF]

open access: yes, 1996
I studied prey preferences of two groups of specialized jumping spiders (Salticidae), ant-eating ('myrmicophagic') species and spider-eating ('araneophagic') species, in the laboratory. Spiders and ants have in common being unusual and dangerous prey for

The central nervous system of whip spiders (Amblypygi): large mushroom bodies receive olfactory and visual input

open access: yes, 2020
Whip spiders (Amblypygi) are known for their nocturnal navigational abilities, which rely on chemosensory and tactile cues and, to a lesser degree, on vision.

Continual Learning for Multimodal Data Fusion of a Soft Gripper

open access: yesAdvanced Robotics Research, EarlyView.
Models trained on a single data modality often struggle to generalize when exposed to a different modality. This work introduces a continual learning algorithm capable of incrementally learning different data modalities by leveraging both class‐incremental and domain‐incremental learning scenarios in an artificial environment where labeled data is ...

Preliminary Survey for Spiders on Antigua, West Indies

open access: yes, 2009
Spiders have a worldwide distribution that comprises all land environments except at the polar extremes. There are now 40,700 named, described species of spiders (Platnick, 2009), thought to represent about one-fifth of the true total.

Expression of posterior Hox genes and opisthosomal appendage development in a mygalomorph spider

open access: yes, 2023
Spiders represent an evolutionary successful group of chelicerate arthropods. The body of spiders is subdivided into two regions (tagmata). The anterior tagma, the prosoma, bears the head appendages and four pairs of walking legs.
