Hunting as anthropogenic sink of biomass or source of carrion? A brief case study based on German hunting bags

open access: yesWildlife Biology, EarlyView.
Dead biomass is a crucial nutrient source for ecosystems. Although hunting residues can subsidize numerous scavenging organisms and are known to drive important zoogeochemical processes at very different scales in the ecosystem, this has received little attention.

Extending the fossil record of late Oligocene non-biting midges (Chironomidae, Diptera) of New Zealand [PDF]

open access: yesPeerJ
Background The modern chironomid fauna of New Zealand is diverse, highly endemic and reflects a complex biogeographical history. This fauna has been important for developing phylogenetic and biogeographic concepts including Brundin’s writings on ...

Fossil Insects of the Dakota Group

open access: yesNature, 1882
THERE are till now, as far as I know, no fossil insects out of the Dakota group published. Among a large number of fossils belonging to this group, and collected by Mr. Chas. H. Sternberg, some of the leaves show insect galls and mines, the latter mostly of a decided Tineid and Tortricid character. Perhaps a list of those plants may be of interest. The

Facing Truths About Population Management

open access: yesZoo Biology, EarlyView.
Populations of wildlife, and domestic animals have large sinks for surplus animals. By contrast, zoos don't. Humans in industrialized societies are socialized with companion animals, i.e. surplus (i.e., typically denied reproduction) originating from unseen breeding cores.

Optimization of Wind‐PV Co‐Generation Systems Using Artificial Bee Colony and Back‐to‐Back Voltage Source Converter

open access: yesIET Smart Energy Systems, EarlyView.
The Graphical Abstract depicts the proposed Artificial Bee Colony algorithm‐based optimal tuning of PI controllers for back‐to‐back Voltage Source Converters in a hybrid wind–PV system. ABSTRACT This paper proposes a hybrid model‐based back‐to‐back voltage‐source converter (B2B‐VSC) system comprising a Photovoltaic (PV) array and a Permanent Magnet ...

Niche occupancy of Jamaican bat caves: Diversity increases isotopic niche packing

open access: yesJournal of Animal Ecology, EarlyView.
Tropical bat caves are home to hundreds of thousands of bats of multiple species. In Jamaica, we found that isotopic niche packing is the likely mechanism of coexistence at more diverse sites. Abstract There are over 1000 documented caves across Jamaica, many of them used by diverse communities of bats.

Overlooked diversity of the predatory fungus gnat Macrocera in Baltic amber

open access: yesActa Palaeontologica Polonica
The genus Macrocera (Diptera: Keroplatidae) is highly diverse, comprising over 200 species distributed worldwide, yet it remains poorly documented in the extensive sciaroid fossil record.

The emergence and complexification of symbolic practices in the Homo lineage: an archaeological and cognitive perspective Émergence et complexification des pratiques symboliques dans la lignée Homo : une approche archéologique et cognitive

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Recent archaeological discoveries, reviewed in this essay, challenge traditional views on the emergence of human symbolic cognition. Once believed to have originated in Europe around 40,000 years ago, new evidence shows it emerged much earlier across diverse regions.
