Keep the bees off the trees: The particular vulnerability of species in the periphery of mutualistic networks to shock perturbations [PDF]

arXiv
We study the phenomenon of multistability in mutualistic networks of plants and pollinators, where one desired state in which all species coexist competes with multiple states in which some species are gone extinct. In this setting, we examine the relation between the endangerment of pollinator species and their position within the mutualistic network.

Wildlife trade and endangered species protection [PDF]

Markets for endangered species potentially generate incentives for both legal supply and poaching. To deter poaching, governments can spend on enforcement or increase legal harvesting to reduce the return from poaching.

Mapping savannah woody vegetation at the species level with multispecral drone and hyperspectral EnMAP data [PDF]

arXiv
Savannahs are vital ecosystems whose sustainability is endangered by the spread of woody plants. This research targets the accurate mapping of fractional woody cover (FWC) at the species level in a South African savannah, using EnMAP hyperspectral data.

Comparative Mitogenomics and Phylogenetic Implications for Nine Species of the Subfamily Meconematinae (Orthoptera: Tettigoniidae)

Insects
Currently, the subfamily Meconematinae encompasses 1029 species, but whole-mitochondrial-genome assemblies have only been made available for 13. In this study, the whole mitochondrial genomes (mitogenomes) of nine additional species in the subfamily ...
