Scott Collins to Present Wed 1/28 Bio Seminar: Effect of Drought and Rainfall Seasonality on Desert Grassland Ecosystems

Dr. Scott Collins will present a talk entitled "Effect of Drought and Rainfall Seasonality on Desert Grassland Ecosystems" at the weekly Biology Department Brown Bag Seminar on Wednesday, 1/28. This talk will include data from projects at the Sevilleta LTER and will begin at noon in 100 Castetter Hall on the University of New Mexico, Albuquerque campus.

Hope to see you there!


Met Central - 2014 Annual Summary

In many ways 2014 seemed to be a carbon copy of 2013. The only good news with respect to non-monsoon precipitation was that it was not as bad as 2013 - actually only the 6th lowest in Sev's 26 year history. As in 2013 monsoon moisture came relatively early although the monsoon contest qualifying storm did not arrive until July 29. With a slightly wetter than normal July, a slightly drier than normal August and a considerably wetter than normal September, the monsoons came in at 151 mm - about 115% of normal. This was still well behind 2013 monsoon of 208 mm.

December 2014 Met Central - Very warm early Very cold late

December had about 3 distinct parts . Early December was extremely warm with daytime highs running near or above 60o F for the first 12 days of the month with one new daily record high set on the 3rd. Then temperatures tumbled back down near normal with a few more warm excursions until Christmas day. Then some really cold air arrived and stuck around through the end of the year.

BEMP Intern Gary Johnston to Work With 10+ Years of Jackrabbit Data from Sevilleta LTER

This spring, UNM Bosque Ecosystem Monitoring Program (BEMP) intern Gary Johnston will work with the Sevilleta Long-Term Ecological Research (LTER) network and the Valles Caldera National Preserve to process over 10 years of jackrabbit survey data as part of an independent study (Biol 499).

November 2014 - Met Central - Yo-Yo Temperatures

November temperatures came in just about average for the month although few of the daily temperatures actually ran at normal. November started warm but a cooling storm brought some early moisture to NM. Unseasonable warmth returned until the 12th when a Polar Express brought extremely cold temperature down through the eastern side of the state with only some of it leaking through into the central part of the state.

Sevilleta LTER Overview

The Sevilleta LTER (SEV) studies fundamental ecological concepts and theories through a comprehensive and interdisciplinary research program guided by the general question:how do abiotic drivers and constraints affect the pulse dynamics and stability of aridland populations, communities and ecosystems?   We focus intensively on Chihuahuan desert grassland and shrubland, juniper savanna and pinon-juniper (PJ) woodland around the Sevilleta National Wildlife Refuge in the Rio Grande Valley in central New Mexico.
