Hechtia mixtecana sp. nov. (Hechtioideae; Bromeliaceae), from Oaxaca, Mexico

open access: yesNordic Journal of Botany, Volume 2026, Issue 5, May 2026.
Botanical explorations carried out in the state of Oaxaca, Mexico, led to the discovery of a new Bromeliaceae: Hechtia mixtecana,which is here described and illustrated. The new taxon is compared with the morphologically similar Hechtia fragilis, Hechtia lyman‐smithii, and Hechtia minuta.

Search for higgsinos decaying to two Higgs bosons and missing transverse momentum in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2022
Results are presented from a search for physics beyond the standard model in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV in channels with two Higgs bosons, each decaying via the process H → b b ¯ $$ \overline{\mathrm{b}} $$ , and large missing ...

Effects of Warming on Growth and Leaf Colonization by Litter Mat‐Forming Fungi in a Wet Tropical Forest in Puerto Rico

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
We took advantage of a long‐running field warming experiment, the Tropical Responses to Altered Climate Experiment (TRACE) located in the Luquillo Experimental Forest in Puerto Rico to evaluate the effects of +4°C warming on relative growth rates (RGR) and time to leaf colonization of a recently senesced leaf for drought‐tolerant species Marasmius ...

Measurement of double-parton scattering in inclusive production of four jets with low transverse momentum in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2022
A measurement of inclusive four-jet production in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The transverse momenta of jets within |η| < 4.7 are required to exceed 35, 30, 25, and 20 GeV for the first-, second-, third ...

Indirect effects of fast‐growing urban development on wildlife in a coastal protected area of Costa Rica

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 3, April 2026.
We studied the effects of urban growth on wildlife near Parque Nacional Marino las Baulas, Costa Rica. Since 1991, buildings increased 1007%, mainly in the buffer zone. We identified eight native species extracting garbage from containers, with raccoons (Procyon lotor) comprising most detections (84%), and four other species being potential sea turtle ...

The “Pesticide Chip”: Chemical Legacies and Agrarian Futures in Costa Rica

open access: yesAntipode, Volume 58, Issue 2, March 2026.
Abstract For decades, agro‐industrial capital has adopted cascading chemical and biotechnical interventions, or fixes, to secure accumulation through the cultivation of monocrops. We develop a framework that centres on how monocrop‐induced susceptibility to pests and pathogens—and the patchwork of fixes to address these—produces uneven chemical ...

White piedra of scalp hair by Trichosporon inkin

open access: yesIndian Journal of Dermatology, Venereology, and Leprology, 2011
White piedra is a rare fungal infection of hair and is reported to be all the more rare on scalp. Trichosporon inkin is usually associated with white piedra of pubic hair. We report a case of white piedra of scalp hair caused by T. inkin. This is the first case reported from India and the fifth case reported worldwide.

Laguna Fuente de Piedra: An example of a dolomite factory recording ~50,000 years of depositional and paleoclimatic evolution

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.

Water Parameters and Hydrodynamics in Rivers and Caves Hosting Astyanax mexicanus Populations Reveal Macro‐, Meso‐ and Microhabitat Characteristics

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...

Comparative genomic analysis of clinically relevant human skin-associated fungi

open access: yesNature Communications
Fungal skin infections represent a significant global health burden, affecting approximately one billion people annually. Despite their prevalence and major global health impact, the molecular mechanisms underlying pathogenicity remain largely ...
