Climate change impacts on bumblebees converge across continents
TLDR
Using long-term observations across Europe and North America over 110 years, testing for climate change–related range shifts in bumblebee species across the full extents of their latitudinal and thermal limits and movements along elevation gradients found cross-continentally consistent trends in failures to track warming through time at species’ northern range limits.

A Review of Hypotheses of Decline of the Endangered American Burying Beetle (Silphidae: Nicrophorus americanus Olivier)
TLDR
It is found that although progress has been made during the past 12 years, even the most well supported hypothesis requires a number of important studies to be completed or extended before one can confidently explain the decline of this species and predict the success of conservation efforts.

Inferring species membership using DNA sequences with back-propagation neural networks.
TLDR
An artificial intelligence-based approach - inferring species membership via DNA barcoding with back-propagation neural networks (named BP-based species identification) - is proposed as a new advance to the spectrum of available methods.

Software manual for PAUPRat: A tool to implement Parsimony Ratchet searches using PAUP*
TLDR
This manual provides a basic introduction to the Parsimony Ratchet and information on how to use PAUPRat, a search strategy that is surprisingly efficient at finding shortest trees for data sets too large for traditional heuristic search methods.
Host shift by the burying beetle, Nicrophorus pustulatus, a parasitoid of snake eggs
TLDR
The efficient use of snake eggs, the ability to regulate brood size and the different responses to snake eggs and carrion suggest that N. pustulatus is well adapted to exploiting snake eggs for breeding.

The reproductive biology of Ptomascopus morio , a brood parasite of Nicrophorus
TLDR
Findings suggest that after the female parent adjusts clutch size to the size of the resource, the only parental benefit is clearing the carcass of fly larvae.

Detection of Francisella tularensis in Alaskan Mosquitoes (Diptera: Culicidae) and Assessment of a Laboratory Model for Transmission
TLDR
It is suggested that although Francisella DNA can be detected in a significant portion of wild-caught mosquitoes, transmission of Francisella is either very inefficient or is species dependent for the Francisella strain or the arthropod vector.
