Tiny Patch, Big Value: A Small Dry Forest Patch Supports Wildlife Conservation in Guanacaste, Costa Rica

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
This study highlights the biodiversity value of the Murren Reserve, a small tropical dry forest patch in Guanacaste, Costa Rica. Using camera traps and opportunistic observations, researchers documented 32 wildlife species, including federally endangered species like the ocelot (Leopardus pardalis) and puma (Puma concolor), as well as 73 plant species.

Drainage in irrigated deserts: Efficient design, installation, and maintenance of drainage systems essential to avoid crop damage by high soil salinity

open access: yesCalifornia Agriculture, 1957
Subsurface drainage is vital in irrigated desert areas and much research on the problem has been and is being done in the Coachella, the Imperial, and the Palo Verde valleys of California.

Public support for puma reintroduction in the eastern United States

open access: yesConservation Science and Practice, Volume 7, Issue 8, August 2025.
We conducted research to assess attitudes about puma reintroduction across eastern states. Both habitat and public support warrant serious consideration of puma restoration. One pathway to creating potential institutional support lies in including locally extirpated species in State Wildlife Action Plans (SWAPs), which are currently under 10‐year ...

Extrinsic CPT Violation in Neutrino Oscillations in Matter

open access: yes, 2003
We investigate matter-induced (or extrinsic) CPT violation effects in neutrino oscillations in matter. Especially, we present approximate analytical formulas for the CPT-violating probability differences for three flavor neutrino oscillations in matter ...

Establishment patterns of saguaro cactus (Carnegiea gigantea) at the microsite scale help explain saguaro regeneration and distributions in heterogenous, regional habitats

open access: yesAmerican Journal of Botany, Volume 112, Issue 6, June 2025.
Abstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.

Metal-loaded organic scintillators for neutrino physics

open access: yes, 2016
Organic liquid scintillators are used in many neutrino physics experiments of the past and present. In particular for low energy neutrinos when realtime and energy information are required, liquid scintillators have several advantages compared to other ...

Changes in composition and structure of a tropical dry forest following intermittent Cattle grazing

open access: yesRevista de Biología Tropical, 2002
In northwestern Costa Rica, cattle are being used as a "management tool" to reduce the amount of combustible material, mainly dominated by Hyparrhenia rufa, an African grass.

California Water Reallocation: Where\u27d You Get That? [PDF]

open access: yes, 2017
When thirsty, Californians often avoid going to the market for more water. Instead, they might borrow some from their rich neighbors, they might sue them or more commonly, they simply take more from users without much of a voice (e.g.

Second-order corrections to neutrino two-flavor oscillation parameters in the wave packet approach

open access: yes, 2006
We report about an analytic study involving the {\em intermediate} wave packet formalism for quantifying the physically relevant information which appear in the neutrino two-flavor conversion formula and help us to obtain more precise limits and ranges ...
