Recent and Rapid Assembly of an Island Species-Area Relationship Threatened by Human Disturbance. [PDF]

open access: yesEcol Lett
The island species–area relationship (ISAR), traditionally studied in millions of years old oceanic archipelagos, remains poorly understood in much younger insular systems. Using fish communities from 79 postglacial peri‐Alpine lakes, we show that classical ISAR patterns can emerge rapidly, contrary to expectations given their young age (< 15,000 years)

Mixed Bat-Hummingbird Pollination Assures Reproductive Success in a Highly Variable Upper Montane Species. [PDF]

open access: yesEcol Evol
We investigated the reproductive biology of Callianthe sellowiana, a high‐altitude Atlantic Forest species with traits associated with both bat and hummingbird pollination. Our results show that both pollinator groups are equally effective, and reproductive success is enhanced when both are present, highlighting the functional and temporal ...

Seasonal variation in soil and plant water potentials in a Bolivian tropical moist and dry forest [PDF]

open access: yes, 2010
We determined seasonal variation in soil matric potentials (¿soil) along a topographical gradient and with soil depth in a Bolivian tropical dry (1160 mm y-1 rain) and moist forest (1580 mm y-1).

Comparative measurements of carbon dioxide fluxes from two nearby towers in a central Amazonian rainforest: the Manaus LBA site [PDF]

open access: yes, 2002
Forests around Manaus have staged the oldest and the longest forest-atmosphere CO2 exchange studies made anywhere in the Amazon. Since July 1999 the exchange of CO2, water, and energy, as well as weather variables, have been measured almost continuously ...

Alkaline Bromodeoxyuridine (BrdU) Comet Assay to Detect Replication-Associated DNA Damage. [PDF]

open access: yesCurr Protoc
Abstract DNA replication is often challenged by endogenous and exogenous sources of DNA damage, which can stall replication forks and result in single‐stranded DNA (ssDNA) gaps, double‐strand breaks (DSBs), and genomic instability. Detecting DNA damage specifically in newly synthesized DNA strands is essential for understanding how eukaryotic cells ...

Framed sheaves on projective space and Quot schemes [PDF]

open access: yes, 2020
We prove that, given integers $m\geq 3$, $r\geq 1$ and $n\geq 0$, the moduli space of torsion free sheaves on $\mathbb P^m$ with Chern character $(r,0,\ldots,0,-n)$ that are trivial along a hyperplane $D \subset \mathbb P^m$ is isomorphic to the Quot ...
