A new paper projecting Joshua tree habitat under future climate based on incredibly high-resolution distribution data, from Joshua Tree Genome Project collaborators at USGS. They estimate up to 80% loss of suitable habitat by 2100 under the worst-case climate scenario.
#JoshuaTree #science

Map of projected future habitat probabilities for Joshua tree populations based on random forest models of presence and absence, for the years 2071-2100 under SSP3-7.0. Parts of the trees' current range, indicated as outlines, are colored to indicate high probability of presence, but many parts are colored to indicate lower probability

A scatterplot of estimated future suitable habitat area in 2021-2040, 2041-2070, and 2071-2020, under three different future climate scenarios and based on modeling from different baseline time frames. In general, less suitable habitat is projected in the latest time period, and less is projected under more sever climate change

Ich werde nicht sagen was passiert ist, aber Ich bitte die Heimvolkshochschule Hustedt ihre Ferienzeiten irgendwo außer ihrem Telefonbeantworter zu hinterlegen (z.B. Google Maps oder der Webseite) ansonsten fährt man 2 Stunden um seinen dort vergessenen Laptop abzuholen und fährt nun zwei Stunden wieder zurück, ohne Laptop.
Rein hypothetisch könnte das einem Menschen widerfahren.

An extension of the SM with vector-like quarks and hypothetical heavy bosons: model independent parametrisation at NLO order
A model independent parameterization of an extension of the Standard Model including vector-like quarks, new heavy gauge bosons and an extra scalar, involving a minimal number of free parameters, is introduced. Theoretical constraints on the model couplings and hypothetical particle masses are established by making use of perturbative unitarity. The production of heavy charged and neutral gauge bosons which subsequently decay to vector-like quarks at the LHC are investigated at both leading-ord…

Modeling Habitat Shifts: Integrating Convolutional Neural Networks and Tabular Data for Species Migration Prediction
Due to climate-induced changes, many habitats are experiencing range shifts away from their traditional geographic locations (Piguet, 2011). We propose a solution to accurately model whether bird species are present in a specific habitat through the combination of Convolutional Neural Networks (CNNs) (O'Shea, 2015) and tabular data. Our approach makes use of satellite imagery and environmental features (e.g., temperature, precipitation, elevation) to predict bird presence across various climate…

The proposed sell-off of federal lands in the Senate budget bill includes a LOT of Joshua tree habitat—the trees grow in some of the largest areas of undeveloped land in the lower 48 states
The place where eastern and western Joshua trees hybridize, north of Creech AFB, is included
